From a VoxEU article today, by Robert N. McCauley with Hiro Ito and Menzie Chinn:
Will the freezing of the Bank of Russia’s foreign exchange reserves undermine the dollar’s predominant role in official foreign exchange reserves? This column examines the aggregate evidence since end-2021 for any reduction in the dollar share of official foreign exchange reserves against a baseline constructed with data from 1999 through 2021. The observed dollar share in March 2024 differs little from the out-of-sample projection based on this baseline. On this showing, official reserve managers have not reduced the role of the dollar since the freeze of the Bank of Russia’s assets.

Note: Projection uses 2021Q4 dollar share of 58.8%, constant of -.121 and coefficient for the effect of valuation change of .735. where the latter two are estimated from quarterly changes in the dollar share over the 91 quarters 1999Q2-2021Q4.
