Dr David Andolfatto, who is Vice President of the St. Louis Fed, has been one of the most forward-looking people at central banks around the world when it comes to crypto-currencies. Here he speaks with Max Rangeley, Editor at The Cobden Centre, and gives his views on what Bitcoin means for commerce, finance, and the dollar itself.
Max: How have you found the reactions to Bitcoin within the Fed?
David: Bitcoin is barely on the radar screen for most Fed researchers and policymakers. This is to be expected, given the large size of the Fed’s balance sheet and the debate over how to conduct monetary policy with the existence of large excess reserves. But I am aware of a small group of researchers scattered throughout the Fed system that seem interested in the Bitcoin phenomenon. Some, like Francois Velde of the Chicago Fed, have written nice primers on the phenomenon. I am also aware of a cryptocurrency workshop that meets monthly at the New York Fed. The reaction of most people (who study it) might be described as “academic agnosticism” in the sense that people are curious, but not enthusiastically in favor or against the idea.
Max: How do you see Bitcoin being used in the future? Do you foresee private currencies being commonly used on the high street alongside state-backed currencies, or remaining largely online phenomena?
David: Who can say how the future will evolve, especially in this space? My best guess is that Bitcoin will find a niche market. It’s cool to use bitcoin to pay for your Starbucks latte on university campuses (this is what my university is doing). It may very well find a place on the high street, at least among some shops catering to the “cool” crowd. But for advanced economies, at least, it is hard to see how consumers will benefit directly by using bitcoins instead of dollars or pounds. As Satoshi Nakamoto wrote in his seminal 2008 paper introducing Bitcoin, “…the [current] system works well enough for most transactions…”
Max: If the use of private currencies became more widespread, do you think that central banks would ever track monetary aggregates in circulation, even if just approximately, much as M2, M3 etc are tracked now?
David: Anything is possible, but I doubt it. One issue is that there many of these “wildcat” currencies, with more appearing every day (every online game has its own currency for example, as do most social media sites). In a sense, these currencies are “local” monies (much like the local currencies that have always existed, like the Ithaca hour, for example). I’m not sure how a statistical agency could keep track of all these little local currencies, or whether it would even be worthwhile to do so. But who knows?
Max: If private currencies were to become widely used around the world, do you think that this could have an effect on the business cycle, since central banks would not have as much control over monetary factors?
David: I do not think it would have much of an effect on the business cycle, which I think is rooted more in “real” and “financial” factors, rather than “monetary” factors, per se.
Max: You mentioned in your presentation on Bitcoin that although supply is fixed, demand can fluctuate significantly, which causes volatility, would you say this is a weakness inherent in private currencies, or is there the possibility that algorithms could evolve to incorporate a degree of elasticity?
David: Remember that Bitcoin is *more* than a private currency: it is a payment system and monetary policy with *no trusted intermediary* involved. Most private currencies entail the use of trusted third parties. EVE online, for example, an online game founded in 2003 has evidently managed its money supply in a manner that keeps its value relatively stable. It may be possible to code an “elastic money supply” rule in the Bitcoin protocol, but it is not immediately clear to me how this might work. Injecting new money into the system would be easy. The tricky part would be in how to destroy money (having the algorithm debit Bitcoin wallets that are secured by private keys).
Max: You mentioned that you welcome the competition for central banks; if private currencies became widely used, could it chip away at American supremacy, a degree of which is based on the dollar, the so-called “exorbitant privilege”?
David: In my view, America supremacy is not based on the dollar. The status of the dollar simply reflects American supremacy, which is based fundamentally on the structure of that economy (something “real” not “monetary”). The America dollar already faces stiff competition from a variety of alternative candidates, including the Yen, the Euro, and gold. If gold cannot displace the USD, why would we expect Bitcoin to?
