Oh no, there's been an error
This article first appeared on the MacroMania blog. Economic exchange depends critically on secure and trustworthy payment systems. Because payment systems are fundamentally about recording and communicating information, it should come as no surprise that payment systems have evolved in tandem with advancements in electronic data storage and communications.
One exciting development of late is Bitcoin--an algorithmic-based, communally-operated money and payment system. I thought I'd take some time to gather my thoughts on Bitcoin and to ponder how central banks might respond to this innovation. Bitcoin is open-source software designed to govern a money and payment system without the aid of conventional intermediaries like chartered and central banks. The role of chartered banks as payment processors is replaced by a communal consensus protocol mining , where transaction histories are recorded on an open ledger the blockchain.
The role of a central bank is replaced by a "fixed" money supply rule Note: nothing is truly "fixed" in Bitcoin since the community could, in principle, "vote" to change program parameters at subsequent dates. This is true, of course, for any system of governance. Bitcoin is about as close as we have come to digital cash. And because the Bitcoin is in relatively fixed supply or so we think , people sometimes refer to Bitcoin as managing a digital-gold system.
Let's think about cash for a minute. Cash is a bearer instrument ownership is equated with possession. Cash payments are made in a P2P manner, without the aid of an intermediary. When I buy my morning coffee, I debit my wallet of cash and the merchant credits her register by the same amount. There is a finality to the transaction unless my coffee is cold and the merchant values my future business. To the extent that cash is difficult to counterfeit, it solves the double-spend problem.
The use of a cash-based payment system is "permissionless" no application process is needed to open a cash wallet, no personal information needs to be relinquished to open an account.
Relatedly, cash is "censorship-resistant," meaning that you can basically spend it as you see fit. Finally, cash is distributed on an invisible ledger, permitting a degree of anonymity. Cash transactions need not leave a paper trail. The digital money issued by banks is different from cash in several respects. One main difference is that transactions between any two traders must be intermediated by a bank. Transactors implicitly trust the bank to do the proper book-keeping and it is this trust that "solves" the double-spend problem for digital bank money.
Bank money is not permissionless. One has to make an application for a bank account and, in the process, relinquish a great deal of personal information that one trusts the bank to keep secure. Bank money is not censorship resistant—banks may not process certain types of payment requests on your behalf.
Of course, bank money leaves a digital trail albeit on a system of closed ledgers with your identity clearly attached to a particular transaction history. So what are the benefits of Bitcoin? The benefits are likely to vary from person to person, but in general, I'd say the following. First, it's monetary policy reduces the "hot potato" motive of economizing on money balances—that is, it offers the prospect of being a decent long-run store of value.
The public key is like an account number and the private key is like a password. Account balances remain secure as long as the private key remains secure. Third, like cash, no personal information is necessary to open an account, so no need to worry about securing private information.
Fifth, Bitcoin can offer a greater degree of anonymity than bank deposit money, but less so than cash unlike cash, the blockchain ledger is visible and public. Sixth, the entire money supply blockchain lives on a replicated distributed ledger—it lives simultaneously everywhere—so that "sending money somewhere" means updating the ledger on all computers everywhere.
There are no banks, there are no borders. As I said, the extent to which consumers value these benefits likely depends on a host of factors. I see potentially large benefits to relatively poor individuals who have limited access to conventional banking services. It is estimated that up to one in four U. The benefits are likely to be greater for poor individuals living in high inflation regimes that do not have access to interest-bearing inflation protected accounts.
First, it is not a unit of account. Because of its monetary policy and its unstable demand, its value is quite volatile over short periods of time, making it inconvenient as a payment instrument even if it is a good long-run store of value. Second, it has the same security properties as cash--losing or forgetting your private key is like losing your wallet.
One could employ the services of a third-party in this regard, but if so, then why not just use a bank? Third, although the user cost of Bitcoin is presently low, the social cost primarily in the form of electricity is high relative to the cost of operating trusted ledgers.
Fourth, because of its cash-like properties, Bitcoin can also help facilitate illicit trade. Of course, the same is true of cash. First, the threat of Bitcoin and of currency substitutes in general places constraints on monetary policy.
In jurisdictions that finance large amounts government spending through the inflation tax, such a constraint may become binding. Second, to the extent that Bitcoin becomes a significant payment instrument or even the unit of account , it might open the door to financial instability.
Experience demonstrates the private sector's desire for maturity transformation or, more generally, the willingness to act on incentives that make funding illiquid assets with short-term debt a preferred balance sheet structure.
The same incentives would presumably be in place in a Bitcoin economy. In principle, demand-like liabilities should trade at a risk premium. But in practice, they may not. Especially in times of economic complacency, they are likely to be viewed as close to perfect substitutes in terms of their money properties, just like bank money and cash today and the way U.
The question is, what happens if and when there is a "bank-run" or "roll-over crisis" on such a system? The situation is exacerbated if Bitcoin is not the unit of account think of European banks issuing loans denominated in USD. Central banks and fiscal authorities would have to think about what, if anything, to do in such circumstances. One solution may be to impose narrow banking restrictions for banks and other entities engaged in Bitcoin-denominated maturity transformation.
My own recommendation is for central banks to consider offering digital money services possibly even a cryptocurrency at the retail and wholesale level. There is no reason why, in principle, a central bank could not offer online accounts, the same way the U. Treasury presently does www.
These accounts would obviously not have to be insured. They would provide firms with a safe place to manage their cash without resorting to the banking or shadow banking sector.
They would give monetary policy an additional instrument—the ability to pay interest on low-denomination money possibly at a negative rate. To the extent paper money is displaced, there would be large cost savings as well.
It's hard for me to see what the downsides are in having a central bank supply digital money. Critics might argue that it leaves people exposed to potentially poor monetary policy. This may be true and, for these people, currency substitutes should be available including Bitcoin. In terms of payments, critics might argue that central bank accounts will be permissioned accounts, requiring the release of personal information, application efforts, that KYC restrictions will apply so not censorship resistant and so on.
To address these concerns, a central bank could go one step further and issue a cryptocurrency Fedcoin offered at a fixed exchange rate where payments are cleared using a Bitcoin-inspired anonymous communal consensus algorithm. I don't think we can expect anything like this in the near future, but it is technologically possible. Of course, people will complain that Fedcoin will inspire illicit trade, etc. But again, the same is true of regular central bank issued cash.

Federal Bank VP: Bitcoin Threat Means Banks Must 'Adapt or Die'
By St. Louis Federal Reserve. The St. Using economic theory, Andolfatto and Spewak see Bitcoin bound between the ultra-bull and ultra-bear forecasts: a non-zero bottom, but no ridiculous tops. Looking at the bullish case, the tandem find that the more altcoins enter the market, the more downward pressure is put on the exchange rate between Bitcoin and altcoins.
St. Louis Fed Economist: Bitcoin Could Be A Good Threat To Central Banks
We use cookies to improve the experience, here is our policy. Since the rise of digital currencies and cryptocurrencies, central banks are considering the role these new forms of money may play in our evolving digital economy. One of the ideas studied is the notion of a central bank digital currency. While people and companies can hold central bank liabilities in the form of cash, only licensed banks have access to digital cash accounts with central banks. David was previously on the podcast to discuss his idea for Fedcoin, a central bank issued cryptocurrency. In a recent paper, he explores the impact central bank digital currencies may have on the monopolistic banking sector. Sebastien Couture : Hi, welcome to Epicenter. My name is Sebastian Couture.

Is Bitcoin a new revolution? : Interview with David Andolfatto Federal Reserve Bank of St. Louis ①
Bitcoin has been hailed as the future of currency but its detractors say its doomed to failure and extreme volatility because of its lack of regulation and state backing. Now economists are considering an alternative federally backed cryptocurrency fixed to the U. Louis, published a blog post on Feb. The key difference between Andolfatto's Fedcoin and cryptocurrencies like bitcoin is that it would have a fixed exchange rate with the U. This would solve what many say is bitcoin's main problem -- its volatility. Bill Gates pointed out in a recent Reddit AMA that he likes bitcoin but his foundation cannot use the currency for a basic reason.
CAD-coin V Fedcoin: The future of central bank digital currencies
Bitcoin is not an investment as I define it. It is a money or a currency. You can speculate in it and trade in it. But I do not think it has a major place for most people as an investment, just like most people would not have South African Rand as an investment. It does reveal facets of modern money, which we often ignore. Money relies on belief.

The likelihood of the Bitcoin system replacing the Federal Reserve as the main provider of money in the United States and the desirability of such a transformation are the topics of this article. Francois Velde of the Federal Reserve Bank of Chicago has estimated that, as of late , the average volume of bitcoin transactions per minute totaled less than four-tenths of 1 percent of average dollar transactions per minute--actually, not total dollar transactions but only the subset conducted by means of Visa credit card payments Velde In the months since the publication of Velde's article the volume of bitcoin payments has been growing rapidly, but their quantitative extent is still negligible from a macroeconomic perspective.

How hard would it be to track these funds and mark them as fully taxable at any point they are redeemed for dollars or any other currency at an exchange? That is, would it be possible to mark a particular bitcoin as having been paid in ransom so that such tainted coins could not be exchanged for dollars at regulated exchanges without first paying a tax?
