More articles on dollar dominance, e.g. in Foreign Policy, Wells Fargo, vs. BitcoinNews. But most of the discussion centers on dollar use in terms medium of exchange etc. (SWIFT use, invoicing).

Will the implementation of sanctions result in reduced dollar holdings? Unfortunately, we don’t have data for the period after the expanded invasion of Ukraine, but we do have estimates encompassing up to 2021.

Note the estimated coefficient is not statistically significant. It’s also nonlinear, so a bit difficult to interpret. Table A1.1 in the paper presents estimates from a linear shares regression for USD holdings (only) so that the coefficient estimate is easier to interpret.

Taken literally, with an autoregressive coefficient of 0.88, the long run impact is 0.05, so that if the US has imposed financial sanctions on a country, on average that country’s central bank will hold 5 percentage points less US dollars. But, the 95% confidence interval encompasses a 6 percentage point increase in dollar shares.Hence, arguments that the use of financial sanctions will erode dollar dominance are not verified empirically, thus far (maybe with data to 2023, we would find something different).More By This Author:An Alternative Civilian Employment Measure
