Money Is Not a Store of Value

Mark Thoma takes us to David Andolfatto on why Bitcoins and gold “make lousy money”:

Imagine having gone to work for gold a few weeks ago, only to see the purchasing power of your wages drop by 10% in one day. Imagine having purchased something using Bitcoin, only to watch the purchasing power of your spent Bitcoin rise by 100% the next day. It would be frustrating.

And why stable inflation isn’t so bad after all:

Is it important for a monetary instrument to hold its value over long periods of time? I used to think so. But now I’m not so sure. While I do not necessarily like the idea of inflation eating away at the value of fiat money, I don’t think that a low and stable inflation rate is such a big deal. Money is not meant to be a long-term store of value, after all. Once you receive your wages, you are free to purchase gold, bitcoin, or any other asset you wish. (Inflation does hurt those on fixed nominal payments, but the remedy for that is simply to index those payments to inflation. No big deal.)

The point Andolfatto is making here is actually intimately connected to a piece by Tim Duy a few days back arguing that the Federal Reserve can only successfully achieve two of: low inflation, full employment, and financial stability. The import of Duy’s argument is that we would have to tolerate significant asset inflation – increasing risk of financial instability – to increase employment without increasing consumer prices.

A lot of what he talked about concerns recent financial dynamics, but it’s worthwhile studying Medieval monetary policy in both considering the veracity of this claim and applying it to Andolfatto’s dilemma. And a new paper by Anthony Hotson at Vox is the perfect place to start. Today we control consumer price inflation, or a basket of goods that the government thinks represent our living expenses. Ipso facto, assets like equity are excluded (they aren’t necessary to live, after all). Back in the good ol’ days, under the gold and silver standards, governments controlled asset inflation. But to do this they had to let consumer prices go haywire:


Or as Hotson explains this dynamic:

There was no parallel in medieval monetary policy to the modern preoccupation with the price of ordinary commodities, as measured by consumer price indices. Indeed, when faced with a change in the relative price of bullion and ordinary commodities, the authorities would resolutely keep bullion prices pegged and allow ordinary commodity prices to adjust. Relative price changes could be significant, not least as a result of new mining discoveries in the Spanish Americas.

This provides pretty solid backing to Duy’s argument that if we provide asset price stability, consumer prices will become highly volatile. And as Andolfatto argues, when the real value of money is highly uncertain on a daily basis – as the annual (light orange) data indicates – it fails to become unit of exchange. Of course there is stability vis-a-vis the money value of bullion, but this is hardly useful on a day-to-day basis.

But my conclusion is slightly different than Andolfatto’s:

If the existence of a gold reserve does not prevent a government from reneging on its promises, then why bother with a gold standard at all? The key issue for any monetary system is credibility of the agencies responsible for managing the economy’s money supply in a socially responsible manner. A popular design in many countries is a politically independent central bank, mandated to achieve some measure of price-level stability. And whatever faults one might ascribe to the U.S. Federal Reserve Bank, as the data above shows, since the early 1980s, the Fed has at least managed to keep inflation relatively low and relatively stable.

He speaks, rightly, that gold is not inherently better than fiat. Because we are using government-issued banknotes, revaluation can cause significant inflation, as did FDR. Arguably, it’s a lot easier to create inflation under a gold standard than with fiat currency. But the gold standard has an even more fundamental flaw, which is that by stabilizing bullion prices, consumer inflation can become highly volatile.

So with the gold standard, the Dollar note becomes what Bitcoin is today, if slightly less volatile. And asset inflation hawks should note that the gold standard only guaranteed the price of gold. If the Fed were to manage asset inflation altogether the consequences to consumer prices would be untold.

Indeed, consumer inflation could be solved by dropping the full employment mandate, and that is his chilling conclusion:

 If Kocherlakota is correct and monetary policy can only pursue the dual mandate in the context of financial – and, by extension – macroeconomic instability, then we really need to consider which part of the dual mandate needs to be loosened to reduce the reliance on financial instability.  My fear is that if Fed policy makers were asked this question, they would unanimously answer that it is the full-employment portion of the mandate that should be jettisoned.

Let’s pay heed to history. Jeremy Stein is smart, and knows that bankers are on a binge of cheap money right now. This might be a reason for expansionary fiscal policy.* But unless we renege on consumer price stability or full employment, now is not the time to cut back.  We save and invest in assets (perhaps gold and Bitcoins). It is important to maintain short term price stability of currency, but not its status as a store of value.

*An interesting question is whether this brings doubt to the “Krugman condition”. Even Krugman, the poster child of fiscal policy, believes it is justified only at the zero lower bound. If financial instability is of key concern, might there be conditions where of tight money and deficits come hand-in-hand?

  1. Deep down…

    Money is not a govt. creation. Nor is monetary policy a good tool for social policy.

    Money is a creation of the haves. Govt. is a creation of the haves. Essentially, the 1/3 of the folks who actually create marginal value, and pay the tab, are the final veto on what money is for. Not the Fed, not the elected officials. The haves.

    Surely you understand that if the Dollar sees 5% inflation per year, BitCoin adoption grows fast, and at 10% it grows even faster.

    So really whats being discussed is how much can you annoy the haves with maco game play without them turning on you, finding you and reducing the quality of your life…. because there is an exact moment when theory meets reality, and the haves throw their weight around, and the economists are paid no mind.

    Thats WHY a far better approach to fiscal policy is GI CYB, where we totally divorce wages from social safety net, and directly show the haves that everyone is being put to use by the private sector.

    This increases haves and the havenots happiness. It increases economic mobility.

    Whats more, it allows you to not say silly things about money, for outlandish effect.

    If you want to shock the world and win the nobel prize, GI CYB is the NGDPLT of Fiscal policy.

    Model it up, put your name on it, you can thank me later.

    If you really want to shock everyone, CODE IT UP as Open Source, and put it on github for any state to use. It’s just a job board on steroids.

  2. “It is important to maintain short term price stability of currency, but not its status as a store of value”. Yes, if you are concerned (only) about daily shopping bills and money’s exchange function; but Hotson’s study shows that is not the historic attitude to money. Maybe they were onto something. If you enter into a loan contract, the sum of the risks borne by debtors and creditors is reduced if the parties are confident in the value of money over the contract period. It is not surprising that investment horizons shortened under fiat money, or inflation targeting, with its two-year+ horizon. I agree that targeting all assets may be impossible and counterproductive. But I have suggested a money tied to a diversified equity basket. Then, the long-term real value of money rises as consumer prices gradually fall with the growth of productivity et al- deflation will lose its horrors because it will be linked to higher standards of living. Long term contracts will be encouraged and money will be perfectly liquid; for more on this, please see “Three kinds of money” post here:

  3. You really make it seem so еasy with yoսr presentation but I find this
    topic to be actually something that I think I would never understand.
    It seems too complex and ѵerʏ broad for me.
    І am looking forward for your next post, I will trу to get the hang of it!
