The summary from article forthcoming within the Journal of Worldwide Cash and Finance.
We start by analyzing determinants of mixture international trade reserve holdings by central banks (measurement of issuing nation’s financial system and monetary markets, skill of the foreign money to carry worth, and inertia). However understanding the dedication of reserve holdings in all probability requires going past the combination numbers, as a substitute observing particular person central financial institution conduct, together with traits of the holding nation (bilateral commerce with the issuing nation, bilateral foreign money peg, and proxies for bilateral publicity to sanctions), along with the traits of the reserve foreign money issuer. On a currency-by-currency foundation, US greenback holdings are considerably properly defined by a number of issuer traits; however the different currencies are much less efficiently defined. It might be that the outcomes from currency-by-currency estimation are impaired by inadequate pattern measurement. This consideration presents a motivation for pooling the information throughout the most important currencies and imposing the constraints that reserve holdings are decided in the identical approach for every foreign money. On this setting, most financial determinants enter with significance: financial measurement as measured by GDP, bilateral foreign money peg, and bilateral commerce share. Whereas one geopolitical issue (congruence in voting within the UN) is often vital within the anticipated method (apart from the US greenback), the opposite geopolitical issue (sanctions) doesn’t enter with significance.
Right here’s an image of the combination foreign money shares, from the IMF’s COFER database, up to date information launched on June eleventh.
Determine 1: Share of international trade reserves held by central banks, in USD (blue), EUR (orange), DEM (tan squares), JPY (inexperienced), GBP (sky blue), Swiss francs (purple), CNY (pink). For 1999 information onward, estimates based mostly on COFER information, and apportionment of unallocated reserves, described in textual content. Supply: Chinn and Frankel (2007), IMF COFER accessed 6/20/2024, and creator’s estimates.
And right here’s a element, for 1999 onward:
Determine 2: Share of international trade reserves held by central banks, in USD (blue), EUR (orange), JPY (inexperienced), GBP (sky blue), Swiss francs (purple), CNY (pink).

Equations used to estimate mixture shares pre-EMU are fairly ineffective in predicting shares now. Therefore, on this new paper, we depend on particular person central financial institution information to estimate the determinants of shares. The outcomes of a pooled cross-country cross-currency, unconstraining the geopolitical distance coefficient to differ throughout foreign money, are reported in Desk 4.

Following the ends in Chinn and Frankel (2007), we discover financial measurement issues, in addition to inertia. Whereas we discover retailer of worth measures (inflation, trade charge volatility) have a adverse influence, these results usually are not statistically vital. This particular information set (central financial institution by yr) permits us to analyze the influence of commerce flows and peg, which seems to be necessary. We replicate the discovering obtained by Goldberg and Hannaoui (2024) that extra geopolitically distant international locations (as measured by coincidence in UN GA voting) maintain better greenback shares, whereas the reverse is true for the opposite currencies. Whereas monetary sanctions have a adverse influence, the measured sensitivity just isn’t statistically vital.
Whereas we don’t explicitly report how greenback shares have declined, it’s helpful to notice that different research (see Arslanalp, Eichengreen and Simpson-Bell (2024), and references therein) have documented that the slack just isn’t typically being principally take up by the RMB, however different unconventional currencies.
