Global dollar-denominated assets have experienced a substantial increase, rising from under $20 trillion in 2013 to over $40 trillion in 2024. This growth represents a near doubling of dollar assets over the past decade. As a share of global GDP, dollar assets expanded from approximately 130% to nearly 200% during the same period, while dollar liabilities remained relatively stable. This widening asymmetry is primarily attributed to advanced economies, where non-bank sectors have increasingly accumulated U.S. dollar assets.
This elevated dollar exposure presents significant currency risk, which investors typically manage through hedging activities like swap or forward contracts. These hedging actions, in turn, influence deviations from covered interest parity (CIP), which signal violations of fundamental no-arbitrage conditions in currency markets. The relationship between net dollar exposures (dollar assets minus liabilities) and CIP deviations is notably negative in advanced economies, meaning larger net dollar exposures lead to more negative CIP deviations. This trend is explained by increased hedging demand in these regions, pushing up hedging costs.
Conversely, emerging markets exhibit a positive correlation between net dollar exposures and CIP deviations. This is primarily due to the supply side of the hedging market. Limited hedging supply in these economies leads to wider (more negative) CIP deviations. This situation encourages firms to borrow in U.S. dollars rather than local currencies, which subsequently reduces their net dollar exposures and contributes to the observed positive correlation.
Recent market events, such as the U.S. dollar's weakness following tariff announcements and Federal Reserve rate cuts, have heightened concerns among investors and policymakers regarding financial instability in countries holding large dollar-denominated assets. The urgency to understand global dollar exposures and their market implications has increased amidst rising macroeconomic uncertainty surrounding U.S. policy. The total global USD-denominated assets amounted to $42 trillion in 2024, a significant increase from $19 trillion in 2013, highlighting the growing importance of USD-denominated securities in international investor portfolios.
