to advance exploration of a United States Central Bank Digital Currency (CBDC). The purpose of the Project is to encourage research and public discussion on the potential advantages of a digital dollar, convene private sector thought leaders and actors, and propose possible models to support the public sector. The Project will develop a framework for potential, practical steps that can be taken to establish a dollar CBDC.
On his blog, JP Koning reports that
[b]oth the Christmas bump and the sawtooth pattern arising from monthly payrolls are less noticeable than previous years. But these patterns remain more apparent for Canadian dollars than U.S. dollars. Not because Canadians like cash more than Americans. We don’t, and are probably further along the path towards digital payments then they are. Rather, the percentage of U.S. dollars held overseas is much larger than Canadian dollars, so domestic usage of U.S. cash for transactions purposes gets blurred by all its other uses.
On Moneyness, JP Koning discusses the ability or not of the U.S. treasury to enforce financial sanctions overseas. Focusing on the Iran sanctions that ran from 2010 to 2015 (with strong international support) and are scheduled to be reimposed soon (without such support) Koning compares the U.S. sanctions regime to an exclusivity agreement that a large retailer imposes on a manufacturer.
Foreign banks in places like Europe were free to continue providing transactions services to Iran, but if they did so they would not be able to maintain correspondent accounts at U.S. banks. To ensure these rules were enforced, U.S. banks were to be fined and U.S. bank executives incarcerated if found guilty of providing accounts to offenders. Fearful bank executives were very quick to comply by carefully vetting those that they offered correspondent banking services to.
Having a U.S. correspondent account is very important to a non-US bank. If a European bank has a corporate customer who wants to make a U.S. dollar payment, the bank’s correspondent relationship with a U.S. bank allows it to effect that payment. Since the revenues from U.S. dollar payments far exceeds revenues from providing Iranian agencies and corporations with payments services, a typical European bank would have had no choice but to abandon Iran in order to keep its U.S. correspondent account.
But what would happen if Iran were to invoice in EUR rather than USD and make payments using an account at a European bank, bank X say, without direct links to the U.S. and no U.S. correspondent account? The answer to that question depends on whether the U.S. treasury would be prepared to sanction a third financial institution, bank Y say, that collaborates with bank X (or a business partner of bank X) and relies on a U.S. correspondent account. In the most extreme scenario bank Y would be the European Central Bank.
One scheme would be to set up a single sanctions-remote bank that conducts all Iranian business. To defang the U.S. Treasury’s threat “do business with us, or them, but not both!”, this bank should not be dependent on U.S. dollar business. Without a U.S. correspondent, the Treasury’s threat to disconnect it from the correspondent network packs no punch. … Crude oil buyers from all over Europe could have their banks wire payments to [bank X’s] account via the ECB’s large value payments sytem, Target2. [Bank X] could also open accounts for companies in India, China, and elsewhere who want to buy Iranian crude oil with euros.
… There is also the extreme possibility that the U.S. would impose travel bans on the ECB itself, in an effort to force ECB officials to remove [bank X] from Target2. Here is one such threat: “Treasury this week designated the governor of Iran’s central bank—does any European country think Treasury can’t designate their own central bank governor too?” Look, the idea of preventing Mario Draghi from travelling to the U.S., or blocking his U.S. assets, sounds so unhinged that it’s not even worth entertaining.
The reason Iran and its trading partners were not able to break sanctions between 2010 and 2015, according to Koning, is that Europe (specifically the German chancellor Angela Merkel) supported the U.S. administration and imposed its own sanctions on bank X, cutting it off the SWIFT and Target2 networks.
From the NZZ:
In a speech, Hyun Song Shin points out that CIP increasingly fails to hold: the Dollar interest rate implied by FX swaps vis-a-vis the Euro, Yen, Pound or Swiss Franc is “too high.” Moreover, the deviation is negatively correlated with the Dollar’s spot exchange rate: When the Dollar appreciates, the deviation from CIP widens.
Shin argues that bank behavior explains the deviation:
… the US dollar is used widely throughout the global banking system, even when neither the lender nor the borrower is a US resident. … The consequence of the dollar’s international role in transactions is that the global banking system runs on dollars.
… key feature of the risk-taking channel is that when the dollar depreciates, banks lend more in US dollars to borrowers outside the United States. Similarly, when the dollar appreciates, banks lend less, or even shrink outright the lending of dollars. In this sense, the value of the dollar is a barometer of risk-taking and global credit conditions.
… The breakdown of covered interest parity is a symptom of tighter dollar credit conditions putting a squeeze on accumulated dollar liabilities built up during the previous period of easy dollar credit. During the period of dollar weakness, global banks were able to supply hedging services to institutional investors at reasonable cost, as cross-border dollar credit was growing strongly and easily obtained. However, as the dollar strengthens, the banking sector finds it more challenging to roll over the dollar credit previously supplied.
One way to summarise the finding is that there is a “triangle” that links a stronger dollar, more subdued dollar cross-border flows, and a widening of the cross-currency basis against the dollar.
With the Euro’s rising role as an international funding currency CIP deviations also show up for the Euro.
… the risk-taking channel for the euro is starting to show the tell-tale negative relationship between a weaker currency value and expanding cross-border lending in that currency; it was not there before the crisis, but has emerged since the crisis.
The financial channel of exchange rates operates when currency appreciation elicits valuation changes on borrower balance sheets. …
When we do international finance, we often buy into the “triple coincidence” where the GDP area, decision-making unit and currency area are one and the same … Currency appreciation or depreciation then acts on the economy through changes in net exports. [But that’s misleading.]
