As of Aug 2026, the Trade-Weighted US Dollar Index stands at 118.06, classified as Moderately Strong. The dollar has moved -2.03% over the past 30 days and -6.50% year-over-year. DTWEXBGS measures the dollar against a basket of currencies of the major US trading partners, weighted by trade volume, normalized to January 2006 = 100. Broad dollar strength is one of the most important macro variables for stablecoins: this page plots it against aggregate stablecoin supply over the same period. Periods of dollar strength and weakness are shown alongside supply, not as cause and effect. The IMF's Understanding Stablecoins[1] discusses currency substitution and capital-flow volatility as macrofinancial channels relevant to offshore demand for dollar-denominated assets.
DXY vs Total Stablecoin Supply
DXY index level (right axis, orange) overlaid with total stablecoin market cap (left axis, green). Regime bands mark Fed policy periods. Watch how the two series move against each other — the relationship differs by period, and idiosyncratic dollarization waves in specific EM corridors run against the broad trend.
DXY Level Over Time
DXY level alone over the selected period. The 110, 115, 120 reference lines mark historically meaningful thresholds: 110 is the long-run average, 115 is moderately strong, 120+ is historically rare and typically reflects either Fed tightening cycles or global crisis-driven flight-to-quality buying.
Historically rare territory. Typically reflects an aggressive Fed tightening cycle (2022) or a global flight-to-quality event (March 2020). Strong dollar drains liquidity from EM and pressures crypto.
Above the long-run average. Often coincides with Fed in tightening or hold mode. Watch for divergence between major-FX-driven DXY moves (broad trend) and EM-driven moves (dollarization signal).
Near or below long-run average. Typically reflects Fed easing expectations or risk-on conditions.
Reflects either active Fed easing, foreign currency strength, or risk-on capital flows leaving USD.
DTWEXBGS (Trade-Weighted US Dollar Index, Broad, Goods and Services): a daily index measuring the foreign exchange value of the US dollar against a basket of currencies of major US trading partners, weighted by trade volumes. Published by the US Federal Reserve, normalized to Jan 2006 = 100.
vs ICE DXY: The ICE DXY index quoted in financial media uses only 6 currencies fixed in 1973, heavily Euro-weighted (~58%). DTWEXBGS uses a broader basket (~26 currencies) rebalanced annually for current trade flows, making it a more accurate measure of US dollar purchasing power across the global economy. The two indices are correlated but not identical: DTWEXBGS is the academic and policy standard; ICE DXY is the trader convention.
Regime thresholds: <108 weak, 108–115 moderately weak, 115–122 moderately strong, >122 strong. These are not formal definitions but reflect historical operating ranges since 2010.
Update frequency: Daily. The Fed publishes DTWEXBGS once per business day, typically by 17:00 ET.
What this page does not prove: DXY and USDT dominance can move together without one driving the other, both may respond to a common third variable (risk-off conditions, geopolitical stress, EM capital outflows). The chart shows co-movement consistent with the dollarization-pressure hypothesis but does not establish causation. For direct EM dollarization evidence, central-bank wallet adoption data is the right source.
