How voluntary was Q1 U.S. dollar reserve buying?

Official U.S. dollar foreign exchange reserves rose by $90 billion in Q1 2025, comprising over half of the total $168 billion increase in global allocated reserves, a notable accumulation given the dollar's broad weakening during the period. Standard Chartered suggests this could reflect reserve managers' efforts to prevent sharper local currency appreciation, opportunistic buying of a cheap dollar, or anticipation of future asset-market turbulence. However, the bank advises caution regarding the IMF COFER data, citing unusually large and potentially revisable changes in other currency holdings, urging investors to defer strong conclusions until data reliability is confirmed.

Analysis

Global central banks increased U.S. dollar holdings by $90 billion in Q1 2025, accounting for 54% of the total $168 billion rise in allocated reserves, according to IMF COFER data. This accumulation is notable as it occurred during a period of broad U.S. dollar weakness. Standard Chartered posits three potential drivers for this behavior: central banks may have been intervening to prevent their own currencies from appreciating too sharply against the dollar, opportunistically buying the dollar while it was perceived as cheap, or building up USD reserves as a safe-haven asset in anticipation of future market turbulence. However, the report's credibility is tempered by a significant caveat from the bank, which highlights unusually large changes of over 30% in Australian Dollar and Swiss Franc reserve holdings. These anomalies suggest the underlying data may be unreliable and subject to future revisions, making it premature to draw firm conclusions about a definitive shift in reserve management strategy.

Key Decisions for Investors

• Treat the Q1 COFER data with significant caution and refrain from making major FX allocation decisions, as the report's key figures may be revised due to noted data anomalies.
• Monitor for confirmation of this U.S. dollar accumulation trend in subsequent data releases before interpreting it as a durable, bullish signal for the currency.
• Investors should watch for any official revisions or explanations regarding the large reported shifts in AUD and CHF holdings, as this will be critical for validating the integrity of the Q1 reserve data.
