Cryptocurrency and Central Bank E-Money

The Atlanta Fed recently hosted a workshop, "Financial Stability Implications of
New Technology," which was cosponsored by the Center for the Economic
Analysis of Risk at Georgia State University. This macroblog post discusses the
workshop's panel on cryptocurrency and central bank e-money. A companion
Notes from the Vault post provides some highlights from the rest of the
workshop.
The panel began with Douglas Elliot, a partner at Oliver Wyman, discussing
some of the public policy issues associated with cryptoassets. Drawing on a
recent paper he cowrote, Elliot observed that there are "at least four substantial
market segments" that provide long-term support for cryptoassets:
• libertarians and techno-anarchists who, for ideological reasons, want a
currency without a government;
• people who deeply distrust their government's economic management;
• seekers of anonymity, who don't want their names associated with
transactions and investments; and
• technical users who find cryptoassets useful for some blockchain
applications.
Besides these groups are the speculators and investors who hope to benefit
from price appreciation of these assets.
Given the strong interest of these four groups, Elliot argues that cryptoassets are
here to stay, but he also asserts that these assets raise public policy issues that
regulation should address. Some issues, such as anti–money laundering, are
being addressed, but all would benefit from a coordinated global approach.
However, he observes that of the four long-term support groups, only the
technical users are likely to favor such regulations.
Another paper, by University of Chicago professor Gina C. Pieters, analyzed the
extent to which the cryptocurrency market is global using purchases of
cryptocurrency by state-issued currencies. She finds that more than 90 percent
of all cryptocurrency transactions occur using one of three currencies: the U.S.
dollar, the South Korean won, and the Japanese yen. She further finds that the
dominance of these three currencies cannot be explained by economic size,
financial openness, or internet access. Pieters also observed that transactions
involving bitcoin, the largest cryptocurrency by market value, do not necessarily
represent a country's cryptomarket share.
Warren Weber, former Minneapolis Fed economist and a visiting scholar at the
Atlanta Fed, discussed so-called "stable coins," one type of cryptocurrency. The
value of many cryptocurrencies has fluctuated widely in recent years, with the
price of one bitcoin soaring from under $6,000 to more than $19,000 and then
plunging to just over $6,000—all within the period from October 2017 to October
2018. This extreme price volatility creates a significant impediment to Elliot's
technical users who would like some method of buying blockchain services with
a currency controlled by a blockchain. In an attempt to meet this demand, a
number of "stable coins" have been issued or are under development.
Drawing on a preliminary paper, Weber discussed three types of stable coins.
One type backs all of the currency it issues with holdings of a state-issued
currency, such as the U.S. dollar. A potential weakness of these coins is that
they incur operational costs that require payment. Weber observed that interest
earnings might cover part of these expenses if the stable coin issuer holds the
dollars in an interest-bearing asset. Additionally, charging redemption fees might
offset some or all of the expense.
The other two alternatives involve the creation of cryptofinancial entities or crypto
"central banks." Both of these approaches seek to adjust the quantity of the

Weber observed that both of these approaches are subject to the problem that
the cryptocurrency could take on many values depending upon people's
expectations. If people come to expect that a coin will lose its value, neither of
these approaches can prevent the coin from becoming worthless.
The question of whether existing central banks should issue e-money was the
topic of a presentation by Francisco Rivadeneyra of the Bank of Canada.
Summarizing the results of his paper, Rivadeneyra observed that central banks
could provide e-money that looks like a token or a more traditional account. The
potential for central banks to offer widely available account-based services has
long existed. However, after considering the tradeoffs, central banks have
elected not to provide these accounts, and recent technological developments
have not changed this calculus. However, new technologies may have changed
the tradeoff for token-based systems. Many issues will need to be addressed
first, though.
