The greenback’s share of world official overseas trade reserves fell from 64 p.c in 2015 to 56 p.c in 2025. This downward trajectory is typically learn as proof that the greenback’s function in worldwide monetary markets is eroding. Nevertheless, combination statistics obscure the composition of modifications occurring on the nation degree. On this put up, we present that the mixture decline is just not a scientific world shift away from greenback belongings. Fairly, the mixture decline displays the actions of a handful of huge reserve holders, altering both their foreign money preferences or the dimensions of their reserve portfolio. From the attitude of the cross part of nations holding greenback belongings, the greenback’s standing in official portfolios is basically intact.
Understanding the Mixture Greenback Shares of Reserves
When economists calculate the greenback share of worldwide official overseas trade reserves, nations with bigger reserve holdings naturally exert disproportionate affect on the ultimate quantity. As Goldberg and Hannaoui (2026) present, this seemingly easy calculation can masks two essentially completely different phenomena. International locations can actively reallocate their current portfolios away from greenback belongings and towards different currencies, which we time period the “preferences channel.” Alternatively, nations can accumulate or decumulate new overseas trade reserves at greenback shares completely different from the worldwide common, which we name the “reserve change channel.” When a rustic with below-average greenback holdings expands its reserves, it mechanically pulls down the worldwide combination, even with out decreasing its personal allocation to {dollars}. From this lens, we are able to interpret the evolution noticed within the chart under, exhibiting the foreign money composition of world overseas trade reserves as reported by the Worldwide Financial Fund (IMF).
Shares of {Dollars} and Large 4 Currencies in International International Trade Reserves Have Declined

Supply: IMF Forex Composition of Official International Trade Reserves (COFER) year-end values.
Observe: Large 4 currencies are USD, JPY, EUR, and GBP.
Two distinct intervals, chosen for availability of information on particular person nation composition of overseas trade reserves, illustrate what drives the aggregates. From 2015 to 2019, the greenback share fell by 3 share factors. From 2019 to 2023, the decline moderated to 2 share factors. The central query is whether or not these combination actions replicate a big set of nations systematically reallocating away from the greenback, or whether or not they stem from the actions of some massive reserve holders making decisions particular to their very own circumstances.
Take into account essentially the most primary indicator: are nations shifting greenback shares of reserves in the identical path? If the mixture decline mirrored a broad-based world shift away from the greenback, most nations would scale back their greenback allocations over these intervals. As an alternative, analyzing directional modifications in greenback share throughout nations throughout each four-year home windows, we discover that roughly equal numbers of nations elevated and decreased their greenback holdings. This stability suggests no dominant cross-sectional shift away from {dollars}. As an alternative, analyzing directional modifications in greenback share throughout nations throughout each four-year home windows, we discover that roughly equal numbers of nations elevated and decreased their greenback holdings, as illustrated within the chart under.
If International locations Are Not All Transferring Away from the Greenback, What Explains the Mixture Decline?
Through the 2015-19 interval, we look at the reserve portfolios of seventy-nine nations, of which seventy-six have full information for the start and finish of the interval. For these seventy-six nations, the mixture decline was break up nearly evenly between the preferences and reserve change channels, which accounted for 1.2 and 1.5 share factors of the decline, respectively, as seen within the chart under. These figures symbolize the web sum of optimistic and adverse country-level contributions inside every channel. Inspecting these underlying contributions reveals that the mixture image masks a excessive diploma of focus.
Adjustments in Preferences for USD Property and within the Dimension of Official Reserves Drive Decline in USD Share from 2015-19
Supply: Authors’ building utilizing information from the IMF Worldwide Monetary Statistics and Chinn and Ito (2020), Arslanalp, Eichengreen, and Simpson-Bell (2022), and Laser, Mihailov, and Weidner (2024).
Notes: The highest 5 largest optimistic and adverse contributors to every channel are offered below a hypothetical change comparable to the noticed 2.8 share level IMF COFER decline from 2015 to 2019. The preferences channel (prime panel) displays every nation’s change in USD share weighted by its 2015 reserve degree. The reserve change channel (backside panel) displays every nation’s change in reserve holdings weighted by the distinction between its 2015 USD share and the 2015 common for the seventy-nine-country pattern. The contributions to the mixture USD share change are in share factors (ppt).
The preferences channel captures lively reallocation choices, such that a big reserve holder shifting away from {dollars} influences the worldwide combination. Through the 2015-19 interval, China and Russia dominated this channel, accounting for many of the 1.2 share level decline attributed to lively portfolio reallocation away from the greenback. Turkey, Peru, and Spain additionally contributed downward strain, although their magnitudes have been a lot smaller, at round adverse 0.2 share level every, whereas Sweden and Switzerland elevated their greenback portfolio shares.
The reserve change channel exhibits an analogous diploma of focus. Switzerland emerged as the most important adverse mechanical contributor to the greenback share of reserves by way of this channel over this particular interval. As a result of Switzerland’s greenback share was under the worldwide common at the beginning of the interval, its large-scale reserve accumulation over 2015-19 mechanically dragged down the cross-country combination greenback share, whilst Switzerland concurrently elevated its personal greenback allocation! The Czech Republic and Russia additionally contributed negatively by way of reserve accumulation at below-average greenback shares. Hong Kong and China, in contrast, contributed positively to this channel, with China’s optimistic contribution reflecting reserve drawdowns over the interval.
These outcomes illustrate that the identical nation can contribute by way of opposing channels concurrently, as was the case for China and Switzerland. With out our decomposition framework, the mixture decline would look like a uniform phenomenon, when in actuality it displays doubtlessly offsetting forces and presumably a small variety of massive gamers.
What Do Out there Information Present for Current Years?
Our information protection for the 2019 to 2023 interval presents each challenges and insights. Full dollar-share information can be found for sixty-two nations, however a number of main reserve holders that reported in 2019 didn’t disclose their 2023 greenback allocations. Amongst these nations with lacking 2023 information, China, Russia, Mexico, and Morocco are the most important reserve holders. The omission of those 4 nations is extremely consequential as they collectively maintain reserves roughly equal in measurement to all the remaining sixty-two-country pattern mixed. To handle this information limitation, we consolidate China, Russia, Mexico, and Morocco right into a single group and characterize their collective contribution below assumptions according to the noticed combination decline of two.3 share factors within the IMF’s Forex Composition of Official International Trade Reserves (COFER) information. This strategy permits us to grasp what function this group will need to have performed to generate the noticed combination motion, given the conduct of the sixty-two nations with full information.
For the sixty-two nations for which we have now full information, the preferences channel is definitely barely optimistic at 0.3 share level, which means these nations collectively elevated their greenback allocations over the interval. The reserve change channel contributes a modest adverse of 0.5 share level. Taken collectively, the identified nation pattern contributes little or no to the mixture decline in greenback share. The image modifications dramatically once we think about the 4 nations for which we do not need full information. Underneath assumptions matching the noticed COFER decline, their implied contribution to the preferences channel is massive and adverse at 2.0 share factors. This implies that the mixture greenback share decline over 2019 to 2023 is sort of totally attributable to the preferences of those 4 nations.
The contributions of particular person nations reinforce this story of focus (see chart under). Amongst nations with full information, Brazil and Hong Kong lowered their greenback allocations, however their contributions are small in magnitude relative to the group for which we have now incomplete information. Switzerland contributes positively to each channels on this interval, a reversal from the precedent days that displays a contraction in reserves. On the reserve change channel, Denmark emerges as the most important adverse contributor to the general 0.5 share level decline, adopted by Bulgaria, Romania, and Poland, all of which expanded reserves from a below-average greenback share. Croatia and the UK contributed positively by way of reserve contraction. The slower tempo of dollar-share decline displays partly the absence of large-scale reserve accumulation over the 2015 to 2019 interval.
Adjustments in Preferences for US {Dollars} Concentrated Amongst a Few International locations Drive The Decline in USD Share from 2019-23
Supply: Authors’ building utilizing information from the IMF Worldwide Monetary Statistics and Chinn and Ito (2020), Arslanalp, Eichengreen, and Simpson-Bell (2022), and Laser, Mihailov, and Weidner (2024).
Notes: The highest 5 largest optimistic and adverse contributors to every channel are offered below a hypothetical state of affairs comparable to the noticed 2.3 share level IMF COFER decline from 2019 to 2023. CN+RU+MX+MA refers back to the combination contribution of China, Russia, Mexico, and Morocco, that are lacking 2023 USD share information. The preferences channel (prime panel) displays every nation’s change in USD share weighted by its 2019 reserve degree. The reserve change channel (backside panel) displays every nation’s change in reserve holdings weighted by the distinction between its 2019 USD share and the 2019 common for the sixty-six-country pattern. The contributions to the mixture USD share change are in share factors (ppt).
What Will the Future Maintain for Greenback Shares in Official Reserves?
The decline within the greenback’s share of overseas trade reserves after 2019 was not a broad-based phenomenon reflecting widespread worldwide reallocation away from greenback belongings. Among the many overwhelming majority of nations we observe, contributions to each channels cluster round zero. The mixture decline is as an alternative pushed by a small variety of massive reserve holders, with China and Russia main by way of lowered portfolio allocations to {dollars}. The reserve change channel displays a rotating group of nations responding to idiosyncratic reserve administration wants slightly than systematic greenback avoidance. Official reserve holdings historically are pushed by nation wants for greenback liquidity, foreign money administration wants, and insurance coverage towards each funding shocks. These drivers nonetheless retain their energy.
For policymakers and market contributors, our evaluation signifies that there’s little proof of a widespread official diversification away from {dollars}, regardless of the decline within the greenback share of combination official reserves. Mixture statistics can create deceptive impressions of broad developments after they truly replicate the concentrated actions of some massive gamers. Understanding this focus is crucial for precisely decoding the greenback’s continued significance in worldwide monetary markets.
