Money, Commodities, Balls, and How Much Deflation is Enough?

Money: How Much Deflation is Enough?

Once again, we see that the cure for all of the world’s ills is quantitative easing. Since there is apparently no downside to QE, it is a shame that we didn’t figure this out earlier. The S&P could have been at 200,000, rather than just 2,000, if only governments and central banks had figured out a century ago that running large deficits, combined with having a central bank purchase large amounts of that debt in the open market, was the key to rallying assets without limit.

That paragraph is obviously tongue-in-cheek, but on a narrow time-scale it really looks like it is true. The Fed pursued quantitative easing with no yet-obvious downside, and stocks blasted off to heights rarely seen before; the Bank of Japan’s QE has added 94% to the Nikkei in the slightly more than two years since Abe was elected; and today’s announcement by the ECB of a full-scale QE program boosted share values by 1-2% from Europe to the United States.

The ECB’s program, to be sure, was above expectations. Rather than the €50bln per month that had been mooted over the last couple of days with little currency-market reaction, the ECB pledged €60bln. And they promised to continue until September 2016, making the total value of QE around €1.1 trillion. (That’s about $1.3 trillion at today’s exchange rate, but of course if it works then it will be much less than $1.3 trillion at the September 2016 exchange rate). To be sure, a central bank always has the prerogative to change its mind, but on the risks of a sudden change in policy please see “Swiss National Bank”. It really is remarkable that Draghi was able to drag the Bundesbank kicking and screaming into this policy choice, and it is certain to end the threat of primary deflation in Europe just as it did in the U.S. and in Japan. It will likely also have similar effects on growth, which is to say “next to nothing.” But in Europe, deflation risks stemming from slow money growth had been a risk (see chart, source Bloomberg).

Interestingly, y/y money growth had already been accelerating as of late last year – the ECB releases M2 with a very long lag – but this puts the dot on the exclamation point. The ECB has said “enough!” There will be no core deflation in Europe.

Commodities: How Much Deflation is Enough?

Last week, in “Commodities Re-Thunk” and “Little Update on Commodities Re-Thunk”, I presented the results of using a generalization of the Erb & Harvey approach to forecast expected long-term real returns for commodities. It occurred to me that, since I have previously played with long-term real equity returns, and we have the real yield on 10-year TIPS as well, that it would be interesting to see if using these figures might produce a useful strategy for switching between assets (which doesn’t change the fact that I am a long-term investor; this is still based on long-term values. We merely want to put our assets in whatever offers the best long term value at the moment so as to maximize our expected long-term return).

The answer is yes. Now, I did a more-elegant version of what I am about to show, but the chart below shows the results of switching 100% of your assets between stocks, commodities, and TIPS based on which asset class had the highest expected real yield at a given month-end. Each line is an asset class, except for the blue line which shows the strategy result.

realswitch

The labels at the top show the asset class that dominated for a long period of time. In 2005 there were a couple of quick crossovers that had little impact, but by and large there were three main periods: from 1999-2005, commodities offered excellent expected real returns; from mid-2005 through early-2008 the strategy would have been primarily in TIPS, and subsequent to that the strategy would have been primarily in equities. Fascinating to me is that the overall strategy does so well even though it would have been invested in equities throughout the crash in 2008. The crash in commodities was worse.

Now what is really interesting is that there is a vertical line at the far right-hand side of the chart. That is because at the end of December, the expected real return to commodities finally exceeded that of equities for the first time in a very long time. For this “selling out” strategy, that means you should be entirely out of stocks and TIPS and entirely in commodities.

As I said, that is the coarse version of this approach. My more-elegant version optimized the portfolio to have a constant expected risk in real terms. It was much less risky as a result (10.5% annualized monthly standard deviation compared to 15.5% for the strategy shown above), had lower turnover, but still sported returns over this period of 9.5% compounded compared to 11.2% for the strategy above. I am not, in other words, suggesting that investors put 100% of their assets in commodities. But this method (along with lots of other signals) is now suggesting that it is time to put more into commodities.

Balls: How Much Deflation is Enough?

Being a football fan, I can’t keep from weighing in on one mystery about deflate-gate (incidentally, why do we need to put ‘gate’ on the end of every scandal? It wasn’t Water-gate, it was the Watergate Hotel that proved Nixon’s undoing. “Gate” is not a modifier). Really, this part isn’t such a mystery but I have seen much commentary on this point: “How did the balls get deflated during the game since they were approved before the game?”

The answer is really simple in the real world: the official picked up one of the balls, said “fine”, and put them back in the bag. He has a million things to do before the championship game and in years of refereeing he has probably never found even one ball out of spec. This sort of error happens everywhere there are low reject rates, and it’s why good quality control is very difficult. (Now, if you fired the ref every time a bad ball got through, you damn betcha those balls would be measured with NASA-like precision – which is perhaps a bad metaphor, since similar issues contributed to the Challenger disaster). The real mystery to me is: if the Patriots truly think they are the better team, why would they cheat, even a little? As with the CHF/EUR cross that we discussed yesterday, the downside is far worse than the gain on the upside.

Or, is it? The NFL will have a chance to establish the cost of recidivism in cheating. Maybe the Patriots were simply betting that the downside “tail” to their risky behavior was fairly short. If the NFL wants to put a stop to nickel-and-dime cheats, it can do that by dropping the hammer here.

Commodities Re-Thunk

January 13, 2015 12 comments

I want to talk about commodities today.

To be sure, I have talked a lot about commodities over the last year. Below I reprise one of the charts I have run in the past (source: Bloomberg), which shows that commodities are incredibly cheap compared to the GDP-adjusted quantity of money. It was a great deal, near all-time lows this last summer…until it started creating new lows.

gdpadjcommod

Such an analysis makes sense. The relative prices of two items are at least somewhat related to their relative scarcities. We will trade a lot of sand for one diamond, because there’s a lot of sand and very few diamonds. But if diamonds suddenly rained down from the sky for some reason, the price of diamonds relative to sand would plummet. We would see this as a decline in the dollar price of diamonds relative to the dollar price of sand, which would presumably be stable, but the dollar in such a case plays only the role of a “unit of account” to compare these two assets. The price of diamonds falls, in dollars, because there are lots more diamonds and no change in the amount of dollars. But if the positions were reversed, and there were lots more dollars, then the price of dollars should fall relative to the price of diamonds. We call that inflation. And that’s the reasoning behind this chart: over a long period of time, nominal commodities prices should grow with as the number of dollars increases.

Obviously, this has sent a poor signal for a while, and I have been looking for some other reasonable way to compute the expected return on commodities.[1] Some time ago, I ran across an article by Erb and Harvey called The Golden Dilemma (I first mentioned it in this article). In it was a terrific chart (their Exhibit 5) which showed that the current real price of gold – simply, gold divided by the CPI price index – is a terrific predictor of the subsequent 10-year real return to gold. That chart is approximately reproduced, albeit updated, below. The data in my case spans 1975-present.

realgoldproj

The vertical line indicates the current price of gold (I’ve normalized the whole series so that the x-axis is in 2015 dollars). And the chart indicates that over the next ten years, you can expect something like a -6% annualized real return to a long-only position in gold. Now, that might happen as a result of heavy inflation that gold doesn’t keep up with, so that the nominal return to gold might still beat other asset classes. But it would seem to indicate that it isn’t a great time to buy gold for the long-term.

This chart was so magnificent and made so much sense – essentially, this is a way to think about the “P/E ratio” for a commodity” that I wondered if it generalized to other commodities. The answer is that it does quite well, although in the case of many commodities we don’t have enough history to fill out a clean curve. No commodities work as well as does gold; I attribute this to the role that gold has historically played in investors’ minds as an inflation hedge. But for example, look at Wheat (I am using data 1970-present).

realwheatproj

There is lots of data on agricultural commodities, because we’ve been trading them lots longer. By contrast, Comex Copper only goes back to 1988 or so:

realcopperproj

Copper arguably is still somewhat expensive, although over the next ten years we will probably see the lower-right portion of this chart fill in (since we have traded higher prices, but only within the last ten years so we can’t plot the subsequent return).

Now the one I know you’re waiting for: Crude oil. It’s much sloppier (this is 1983-present, by the way), but encouraging in that it suggests from these prices crude oil ought to at least keep up with inflation over the next decade. But do you know anyone who is playing oil for the next decade?

realcrudeproj

For the sake of space, here is a table of 27 tradable commodities and the best-fit projection for their next 10 years of real returns. Note that most of these fit a logarithmic curve pretty reasonably; Gold is rather the exception in that the historical record is more convex (better expectation from these levels than a pure fit would indicate; see above).

tableofproj

I thought it was worth looking at in aggregate, so the chart below shows the average projected returns (calculated using only the data available at each point) versus the actual subsequent real returns of the S&P GSCI Excess Return index which measures only the return of the front futures contract.

realindexproj

The fit is probably better in reality, because the actual returns are the actual returns of the commodities which were in the index at the time, which kept changing. At the beginning of our series, for example, I am projecting returns for 20 commodities but the 10-year return compares an index that has 20 commodities in 1998 to one that has 26 in 2008. Also, I simply equal-weighted the index while the S&P GSCI is production-weighted. And so on. But the salient point is that investing in spot commodities has been basically not pretty for a while, with negative expected real returns for the spot commodities (again, note that investing in commodity indices adds a collateral return plus an estimate 3-4% rebalancing return over time to these spot returns).

Commodities are, no surprise, cheaper than they have been in a long while. But what is somewhat surprising is that, compared to the first chart in this article, commodities don’t look nearly as cheap. What does that mean?

The first chart in this article compares commodities to the quantity of money; the subsequent charts compare commodities to the price level. In short, the quantity of money is much higher than has historically been consistent with this price level. This makes commodities divided by M2 look much better than commodities divided by the price level. But it merely circles back to what we already knew – that monetary velocity is very low. If money velocity were to return to historical norms, then both of these sets of charts would show a similar story with respect to valuation. The price level would be higher, making the real price of commodities even lower unless they adjusted upwards as well. (This is, in fact, what I expect will eventually happen).

So which method would I tend to favor, to consider relative value in commodities? Probably the one I have detailed here. There is one less step involved. If it turns out that velocity reverts higher, then it is likely that commodities real returns will be better than projected by this method; but this approach ignores that question.

Even so, a projected real return now of -2% to spot commodities, plus a collateral return equal to about 1.9% (the 10-year note rate) and a rebalancing return of 3-4% produces an expected real return of 2.9%-3.9% over the next decade. This is low, and lower than I have been using as my assumption for a while, but it is far higher than the expected real returns available in equities of around 1.2% annualized, and it has upside risk if money velocity does in fact mean-revert.

I will add one final point. This column is never meant to be a “timing” column. I am a value guy, which means I am always seen to be wrong at the time (and often reviled, which goes with the territory of being a contrarian). This says absolutely nothing about what the returns to commodities will be over the next month and very little about returns over the next year. But this analysis is useful for comparing other asset classes on similar long-term horizons, and for using useful projections of expected real returns in asset allocation exercises.

[1] In what follows, I will focus on the expected return to individual spot commodities. But remember that an important part of the expected return to commodity indices is in rebalancing and collateral return. Physical commodities should have a zero (or less) real return over time, but commodity indices still have a significantly positive return.

Winter is Coming … But Not Here, Not Yet

January 12, 2015 5 comments

We began 2014 with the perspective that the economy was limping along, barely surviving. A recession looked possible simply because the expansion was long in the tooth, but there weren’t any signs of it yet. Equity markets were priced for robust growth, which was clearly not likely to happen, but commodities and fixed-income markets were priced for disaster which was also not likely to happen. The investing risks were clearly tilted against stocks and bonds, given starting valuations, but although the economic landscape appeared weak it was not horrible.

Beginning 2015, the economic news is much better – at least, domestically. Unemployment is back to near levels associated with mid-cycle expansions, although there are still far too many people not in the workforce and a still-disturbing number of people who say they “want a job now” and would take one if offered (see chart, source Bloomberg).

More encouraging still, commercial bank credit growth is back to near 8% y/y, which is consistent with the booms of the past 30 years (see chart, source FRB). And this number excludes peer-to-peer lending and other sorts of credit growth that occur outside of the commercial bank framework, which is likely additive on a multi-year time frame.

The dollar is up and commodities are down, both of which are good for the US economy generally although bad for some groups of course (notably the oil patch). But the US is a net consumer of commodities, so commodity bear markets are good for US growth.

Outside of the US, though, things are looking decidedly worse. Although European core inflation recently surprised on the high side, it is still only at 0.8% and with GrExit a real possibility it is very hard to get bullish economically on the continent. China’s growth is softening. Emerging markets are not behaving well, especially the dollarized economies.

This recent development of the US as an island of relative tranquility in a sea of disquiet is interesting to me. Why are interest rates in the US so low, given that our economy is growing? 30-year interest rates at 2.5% and 10-year rates at 1.90%, with core inflation at 1.7% (and median inflation, as I like to point out because it isn’t influenced by outliers, at 2.3%) seems dissonant as the economy grows at 2.5%-3% and inflation in the US seems reasonably floored in the long run at 1.5%-2.0% as long as the Fed is credible.

This isn’t a new phenomenon, but I think the causes are new. Over the last five years, nominal interest rates were lower than they ought otherwise have been because the Fed was buying trillions of Treasuries and squeezing investors who needed to own fixed income. But the Fed is no longer buying and the Treasury is still issuing them. So I believe the causes of low interest rates now are different than the causes were over the last half-decade. Specifically, the causes of low interest rates in the last five years were sluggish global growth and extensive central bank QE; the causes currently are flight-to-quality related.

It seems weird to talk about a “flight to quality” in US bonds without stocks also plunging. But we have an analog for this period. Here is where I depart totally into intuition, which is in this case driven by experience. This period of interest rates declining while growth rises, as the economy continues a rebound after a long recession, with commodities declining and stocks rising, feels to me like late 1997. It feels like “Asian Contagion.”

Back in 1997, there was a lot of concern about how the Asian financial crisis would spill into US markets. Rates dropped (100bps in the 10y between July 1, 1997 and January 12, 1998), commodities dropped (the index now known as the Bloomberg Commodity Index fell 25% between October 1997 and June 1998), the S&P rallied (+23% from November 1997-April 1998), and GDP growth printed 5.2%, 3.1%, 4.0%, and 3.9% from 1997Q3 to 1998Q3. Meanwhile, Asian markets and economies were all but collapsing.

There was much fear at the time about the impact that the Asian Contagion would have on the US, but this country never caught a cold partly because (a) interest rates were depressed by the flight-to-quality and (b) declining commodities, especially energy, are bullish for US growth overall. We did not, of course, escape unscathed – later in 1998, a certain large hedge fund (which was small compared to some hedge funds today) threatened to cause large losses at some money center banks, and the Fed stepped in to save the day. That was a painful period in the equity market, but the effect from the Asian crisis was indirect rather than direct.

The parallels aren’t perfect; for one thing, bond yields are much lower and equity multiples much higher than their equivalents of the time, and commodities had already fallen very far before the recent slide. I would be reluctant to expect another hundred basis point rally in bonds and another large rally in stocks from these levels, although 1997-1999 saw these things. But history doesn’t repeat – it rhymes. I seem to hear this rhyme today.

Why does it matter? I think it matters because if I am right it means we are witnessing the end of long-term crisis-related markets, but they are masked by the arrival of short-term crisis-related markets. This means the unwind that we would have expected from the Fed’s ending of the purchase program – a slow return to normalcy – might instead end up looking like the unwind that we can get from short-term flight-to-quality crisis flows, which can be much more rapid. Again, this is all speculation and intuition, and I present no proof that I am right. I am merely proposing this speculation for my readers’ consumption and consideration.

The Dollar and Commodities – Just Friends

June 11, 2014 4 comments

The recent, aggressive ECB ease, combined with some mild Fed growls about increasing rates “at some point,” ought to be good news for the dollar against the Euro. And so it has been, although as you see in this weekly chart (source: Bloomberg) the weakening of the Euro has been (a) mild and (b) started more than a month before the ECB actually took action. (Note that the units here are dollars per Euro).

eur

Even though the ECB did considerably more than expected, much of that was in the form of a promise; until the body takes concrete steps towards implementing some of the new QE forms, the decline in the Euro is likely to be relatively slow and steady. Similarly, although the Yen has stopped weakening in 2014, I expect that trend has further to go as long as the Bank of Japan doesn’t lose its nerve with easing. In any event, both of those central banks seem at the moment to be more dovish than the Fed, which augurs for dollar strength.

Is that bad for commodities? The conventional wisdom is that since many commodities trade in dollars, a strong dollar implies weak commodities and vice versa.

There is some support for this view. The chart below (source: Bloomberg) shows weekly levels of the dollar index versus the DJ-UBS index, going back to 1996 or so. The correlation is okay, at -0.725.

dollarcommod

Note, though, that this is a correlation of levels. If you look at a correlation of changes, which is what you would need to use dollar movements as a trading model for commodities, it is effectively zero. (These two series aren’t lovers, moving together always, but just friends coming together to the same place from time to time). Moreover, the regression of levels says that commodities are currently 15% or so cheap – the red smudge on the chart shows the current levels (yet another way that commodities appear to be cheap). Finally, the beta is quite low: if the dollar index rose 20%, it would correlate with roughly a 20% decline in commodities…if commodities preserved the same level of cheapness. To be sure, that is a sizeable drop but a 20% rise in the dollar would put it at levels not seen in more than a decade.

In any event, be careful not to confuse the nominal dollar price of commodities with the real price (I’ve made this argument from time to time in many contexts – see for example here, here, and here). Although changing the value of the dollar will diminish the price of commodities in dollars relative to what they would otherwise would be, if the global price level rises then the price of commodities will rise with it – they just may rise less than they otherwise would. And, since commodities typically experience their highest inflation “beta” at the beginning of an increase in inflation, it is reasonable to expect that commodities’ rise will be enough to cause any dollar-inspired softness to be completely obscured.

You still want to be long commodities if we are in an inflationary upswing, regardless of what the Fed does. And, needless to say, I am somewhat skeptical that the Fed will do anything particularly aggressive on the tightening side!

After All, Tomorrow Is Another Day

“I can’t think about that right now. If I do, I’ll go crazy. I’ll think about that tomorrow.” – Chancellor Merkel

Actually, that quote is from Scarlett O’Hara in Gone With The Wind, but it may as well apply to the EU leaders who announced today that the much-heralded summit meeting this weekend would be delayed until ‘no later than’ next Wednesday. The cited reason is that there are still some issues to be worked through before “final agreement” can be reached. I don’t know about you, but that sounds like the NBA labor dispute. If they knew when they were going to reach a final agreement, then they would have reached an agreement. Methinks this is more an admission that the issues aren’t so easily brushed aside as the early-week rumors of a resolution suggested. The good news is that this means we don’t have to trade down into the weekend and then up on Monday (or up into the weekend and then down on Monday) on the basis of expectations set and dashed.

Europe is still hogging the headlines. The Philly Fed index was great, printing +8.7 versus -9.4 expected (-17.5 last month), on strength in New Orders and Shipments. The Number of Employees subindex, curiously, declined. This has been a wild year for Philly Fed. In March it reached a 27-year high at 43.4; in August it reached a 3-year low at -30.7. Remember that this is a relative-strength indicator: respondents describe how conditions are relative to the prior month. The huge swings show great instability in the rate of growth, due to everything from tsunamis and nuclear meltdowns to Middle Eastern riots to large-scale government intervention. I wonder if the significance of Philly Fed right now is less about its level and more about its volatility. It must be hard to make long-term investment decisions in a business when conditions are changing so violently from one month to the next.

Philly Fed has not given much insight recently, but I wonder if the volatility implies something about visibility?

This may also be the reason behind the strong TIPS auction. While the level of real yields is awful, part of TIPS’ appeal is in the option-like character of inflation. That is, if you are wrong owning TIPS here compared to nominal bonds, then you lose a little bit (we’re not going to have -5% inflation for 30 years, and even if we did you’d get par back), but if inflation develops there’s no reason it can’t be +5% or more. So again, the uncertainty about the economy may contribute to the bid. Put another way, there may be interest from nominal bondholders who are more interested in getting a 1% real yield with certainty than some chance of a +2% real yield and some chance of a -3% real yield over the holding period of the bond.

On the flip side of inflation, copper was killed today, falling more than 5%. “Doc Copper” is 34% below its highs (see Chart) and at the lowest level in a year. I think copper doesn’t have the leading indicator character that it used to have (at least in legend), and I think that it isn’t likely to stay down with the world awash in cash (M2 is still rising at 15.2% annualized over the last 26 weeks), but it is a warning sign that should be recognized.

Doc Copper is feeling a little run-down himself these days.

It may seem odd, after looking at copper, to address the question, “Are Commodities In A Bubble?” True to form, perhaps, I am less interested in the answer than in a way to attack the question. Commodities are not like capital market assets such as stocks and bonds which represent an ongoing source of value and a stream of income. A bond pays a coupon or interest at maturity; a stock pays dividends or (hopefully) increases in value over time as the company retains earnings. Because these instruments have definable cashflows, even if they are speculative, they can be analyzed with tools such as net present value analysis or a dividend discount model. But commodities have no ‘yield to maturity.’ You get no dividend from Zinc. And that means we can analyze the current value of a commodity with respect to its supply and demand but otherwise relative value tools are scarce.

But wait, analyzing the current value of a commodity with respect to its supply and demand is already done through the mechanism of price discovery. In transparent markets, it is hard to argue that any particular price represents in itself a ‘bubble’ or ‘deep value.’ Unless there is some reason that prevents the market from clearing normally, the spot price will be driven by the utility of the good for the purposes of consumption.

(As an aside, the demand from commodity index funds that acquire risk through futures contracts does not, cannot, affect the spot price in a meaningful way. This is because for every long contract there is a short contract, and commodity index funds generally roll so as to never take delivery. This may affect futures prices and contangoes/backwardations, but not spot prices. On the other hand, ETFs that hold physical commodities may, by removing commodities from circulation, affect the spot price over time. But this is not a key part of what I am talking about today.)

So what should we mark commodities against? I choose: money.

Commodities, by their nature, should have a zero real return over (a long period of) time. A pile of copper remains a pile of copper. A bar of gold remains a bar of gold. Thus, if the price of a commodity changes over a long period of time, it is probably more accurate to say that it is the unit of account that is changing value. An ounce of gold doesn’t go from $500 to $1000; a dollar goes from 1/500th of an ounce of gold to 1/1000th ounce of gold. This is, of course, the argument of hard-money adherents. I don’t understand why only gold will do – and don’t want to conduct that argument – but the general point is reasonable.

So we want to compare commodities over time to money. Is the price of commodities out of line given the amount of money in circulation?

This is a harder question to answer than it sounds like. The absolute amount of M2 money has grown enormously over a long period of time. In 1959, M2 was $298bln. In 1989, M2 was $3.2trillion. In 2009, $8.5 trillion. Obviously, commodities prices have not grown anything like that amount. This is because the amount of money must grow over time to maintain a constant price level, if GDP is to keep rising. Remember MV≡PQ. If velocity is stable, and prices are stable, then M must grow with output. Of course, velocity is not stable, although M2 velocity happens now to be back in the general range it inhabited from 1960-1990. And of course, in principle, the Fed doesn’t want prices to be precisely stable, either, since a small amount of inflation is seen to have much lower costs and risks than a small amount of deflation. So if we plot M/Q, we expect to see it rise slowly over time. In fact we do, as the chart below shows (incidentally, don’t be concerned about the units on any of these costs. They are artificial; it’s the trend that matters. For example, the chart below shows how many dollars are in circulation for every dollar of output, but the axis units will be different if I use, say, 1982 dollars rather than 2005 dollars as we have here).

M2 compared to real GDP

So again, charts of commodities ought to look something like the chart above. There is more money in the system, but it’s really how much more money there is relatively since a larger economy needs more money just to keep prices stable.

I compare “economy-adjusted money” to commodity prices in the chart below using the CRB (which I use mainly because it has a long price history). I think a case can be made that commodities may have been ‘bubbly’ in the 1970s and perhaps in 2008 they were starting to get there, but it’s hard to look at this chart and see a big bubble now.

CRB compared to economy-adjusted money

Now, certain commodities might be. This is perhaps not as good a way to compare value for individual commodities because for them we also need to consider more microeconomic demand and supply and, especially, long-term changes in the supply dynamic, but we can get an idea of general trend. Live Cattle and Wheat certainly don’t look bubbly. Note that if we didn’t adjust Live Cattle, it looks very much like the M2/GDP chart: it slopes upward and to the right. Ditto Wheat, although to a lesser extent. Adjusted by “economy-adjusted money,” both of these look about fair.

Wheat and Live Cattle (chosen for random illustration)

Crude oil between 1986 and 2003 was pretty stable, and started to look expensive thereafter. To be fair, there are some questions about long-term supply in oil (Peak Oil and all that). I won’t say anything about Gold, because whatever I say makes somebody mad. You judge. I’ve written before about how it makes some sense to think about Gold as an in-the-money straddle on inflation.

Gold and Crude Oil have more interesting stories (and they always do).

Finally, and perhaps surprisingly, I threw in two financial assets that are often thought  of as inflation hedges for different reasons. The chart below shows the adjusted ratios of stock prices and median existing home sales prices to economy-adjusted money. Home prices look pretty reasonable on a long time scale; stocks less so, but of all of these charts I have the least intuition about how stocks should look through this lens.

Is this a reasonable way to 'deflate' financial assets?

So my overall perspective is that the symptom of high prices of certain commodities and of commodities in general in no way should produce a diagnosis of a bubble in commodities. Feel free to disagree and comment…I’m not saying this is the final word on the subject!
