Would Warren Buffett buy green pieces of paper?


Noah Smith has an interesting post in which he asks: "Is money fundamentally worth nothing more than the paper it's printed on?"

He goes into some soul searching on the definition of "fundamental." His concern with definitions is helpful. The recent debt super-debate was largely blown out proportion due to definitional differences, in my opinion.

If anyone is worthy of describing the word fundamental, it's the sage of Omaha. In deciding whether to purchase a stock or not, Warren Buffett conceptualizes the problem by imagining that he'll never be able to sell it again. He's stuck with it forever. If you abstract from an asset's ability to be exchanged onwards, what you're left with is pure fundamental value. This applies to commodities and consumer goods as well as it does to financial assets.

The definition of fundamental having been dealt with, we're left with a thorny problem. The word money is still undefined. As Neil Wallace pointed out, "monetary theories should not contain an undefined object labeled money." Is Noah talking about gold, cattle, gold-backed bank notes, bitcoin, yap stones, Federal Reserve notes?

In nomadic societies, cattle were highly liquid. What was a cow's fundamental value? Assume that it could never be exchanged again. What remains is the cow's fundamental value — it might be eaten, it could be used to make clothing, it can help rear more cows, it can help in the fields etc. Take another form of "money". In the 1800s, most bank notes were issued with gold redemption clauses. What was a gold-backed bank note's fundamental value? Assume that a note can never be exchanged onwards, and you're left with a security with some fine print on it that says that the issuing bank will redeem it for gold. Its fundamental value is the value of the underlying metal.

I'm going to assume that by green pieces of paper, Noah is specifically interested in the fundamental value of fiat money, perhaps Federal Reserve notes. Assume that a specific FR note, say the one in your wallet, can never be exchanged onwards. What is it worth?

This isn't an economic question. It's a question of security analysis. What does the fine print of your FR Note say? FR notes are liabilities of the Federal Reserve. They carry a "first and paramount lien" on the assets of the Federal Reserve. Having a first lien means that an FR note holder ranks higher than all other Federal Reserve creditors. In other words, your note is an excellent claim. What are the Fed's assets? They have a bunch of government bonds, some gold,* and a few foreign currency denominated assets. These assets aren't paid out on demand. Rather, as a note holder you'd have to wait for the Federal Reserve to be wound up before you could get their hands on these assets. So the fundamental value of an non-exchangeable FR note is the distant possibility that the note holder gets to exercise their senior claim on underlying Federal Reserve assets. That possibility is worth some non-zero value.

see chart in scribd.

This all reminds me of an old conversation I had with Nick Rowe. See here. In that conversation, Nick uses the same Buffetian concept of fundamental value as I use in this post, and argues that fiat money has no fundamental value. I argue the opposite.

Ok, that's my answer to Noah's question.

An interesting thought game is to consider what would happen if all FR notes are no longer exchangable. Say that for some reason or other, no one will accept notes anymore. The price of FR notes would immediately plunge towards their fundamental value. But a large component of a note's fundamental value is derived from the underlying value of the bonds which the Fed holds on its balance sheet. Because these bonds promise to pay a fixed quantity of dollars, the bonds themselves would simultaneously plunge in value along with the notes. And as the bonds plunge in value, the notes do too. And as the notes fall in value, the bonds plunge again etc. etc. until they both spiral to zero.

What halts this spiral is that the Fed holds more than just nominal bonds. It also owns some US dollar assets that pay an inflation-linked return, namely Treasury Inflations Protected notes. At the same time they hold gold. Lastly, they hold foreign denominated bonds whose value would be protected. At some much lower price for FR notes, the Warren Buffetts of the world calculate that the value of a note's senior claim on gold, TIPS, and forex is probably worth more than the market price of notes, and they step in to buy. The death spiral ends.


*the Fed doesn't actually own gold. It owns claims to gold. See this article.

Shadow banks want in from the cold

Remember when shadow banks regularly outcompeted stodgy banks because they could evade onerous regulatory requirements? Not any more. In negative rate land, regulatory requirements are a blessing for banks. Shadow banks want in, not out. In the old days, central banks imposed a tax on banks by requiring them to maintain reserves that paid zero percent interest. This tax was particularly burdensome during the inflationary 1970s when short term rates rose into the teens. The result was that banks had troubles passing on higher rates to savers, helping to drive the growth of the nascent U.S. money market mutual fund industry. Unlike banks, MMMFs didn't face reserve requirements and could therefore offer higher deposit rates to their customers. To help level the playing field between regulated banks and so-called shadow banks, a number of central banks (including the Bank of Canada) removed the tax by no longer setting a reserve requirement. While the Federal Reserve didn't go as f...

The bond-stock conundrum

Here's a conundrum. Many commentators have been trying to puzzle out why stocks have been continually hitting new highs at the same time that bond yields have been hitting new lows. See here , here , here , and here . On the surface, equity markets and bond markets seem to be saying two different things about the future. Stronger equities indicate a bright future while rising bond prices (and falling yields) portend a bleak one. Since these two predictions can't both be right, either the bond market or the stock market is terribly wrong. It's the I'm with stupid theory of the bond and equity bull markets. I hope to show in this post that investor stupidity isn't the only way to explain today's concurrent bull market pattern. Improvements in financial market liquidity and declining expectations surrounding the pace of consumer price inflation can both account for why stocks and equities are moving higher together. More on these two factors later. 1. I'm with...

Does QE actually reduce inflation?

There's a counterintuitive meme floating around in the blogosphere that quantitative easing doesn't do what we commonly suppose. Somehow QE reduces inflation or causes deflation, rather than increasing inflation. Among others, here are Nick Rowe , Bob Murphy , David Glasner , Stephen Williamson , David Andolfatto , Frances Coppola , and Bill Woolsey discussing the subject. Over the holidays I've been trying to wrap my head around this idea. Here are my rough thoughts, many of which may have been cribbed from the above sources, though I've lost track from which ones. Let's be clear at the outset. Inflation is a rise in the general price level, deflation is a fall in prices. QE is when a central bank purchases assets at market prices with newly issued reserves. In equilibrium, the expected returns on all goods and assets must be equal. If they aren't equal then people will rebalance towards superior yielding assets until the prices of these assets have risen high...
