DTWEXBGS 2024-2026: Persistent Dollar Strength Despite Fed Cuts

September 2024, the Fed launched its cutting cycle: -175 cumulative basis points through December 2025. The broad dollar (DTWEXBGS) fell just 1.7% between September 17, 2024 and June 12, 2026, after peaking at 130.0 in January 2025. Three competing hypotheses feed the analysis.

This piece maps the three readings of the paradox. It does not arbitrate: none has yet received exclusive empirical validation.

The 2024-2026 dollar cycle produces a macro-reading anomaly: a broad dollar almost unchanged at the end of a full cutting cycle. The Federal Reserve lowered its target range by 175 basis points, from 5.25-5.50% to 3.50-3.75%, in six decisions between September 2024 and December 2025 (FRED data, DFEDTARL and DFEDTARU series). Between September 17, 2024, the eve of the first cut, and June 12, 2026, DTWEXBGS moved from 121.6 to 119.5, or -1.7%. On October 2, 2026 it stood at 121.4, 0.2% below its starting level, after the Fed raised its target by 25 basis points on September 16, 2026, to 3.75-4.00%. The gap between expected and observed is precisely what this cluster, and notably the reading of DTWEXBGS as a systemic strength signal, seeks to make explicit.

The documented paradox

The common reading links lower short rates to a weaker currency. Uncovered interest-rate parity, at the core of Dornbusch’s 1976 overshooting model, does tie the rate gap to the expected path of the exchange rate, but the amplitude depends on expectations and risk premia: the literature sets no standard sensitivity per 100 basis points.

DTWEXBGS followed a rougher path than a simple resilient dollar: +6.9% from September 17, 2024 to a 130.0 peak on January 13, 2025, in the middle of the cutting phase, then -9.7% to a 117.4 trough on January 29, 2026, before drifting back toward 121 in autumn 2026. This small net decline, against 175 basis points of cuts, is the phenomenon to explain. It does not mean parity is invalidated, parity is not a law of physics but a theoretical equilibrium condition, but it means other forces operate and offset the expected effect of Fed cuts on the currency. DTWEXBGS only starts in January 2006: any comparison with earlier cycles runs through other indices, as the historical taxonomy of dollar cycles does.

Three hypotheses are currently debated in central-bank and clearinghouse literature: the growth differential, the fiscal risk premium via term premium, and defensive attractiveness in a phase of geopolitical fragmentation. None is exclusive; they may operate simultaneously with variable relative weights. Our ACM term-premium series sets out how the indicator is built.

Hypothesis 1: the U.S. growth differential

The first reading rests on the expected growth differential. According to the World Bank (Global Economic Prospects, June 2026), expected 2026 U.S. growth is +2.2%. Euro area: +0.8%. Japan: +0.7%. The U.S. differential against major developed economies is documented and significant.

The proposed mechanism: a growth differential attracts long-term capital flows toward U.S. assets (equities, corporate bonds, listed real estate, FDI) independently of the short-rate gap. These flows mechanically support the dollar through demand for dollar-denominated assets. The link remains an interpretation: the June 2026 Global Economic Prospects provide the growth projections, not their effect on the exchange rate. A closer look: our frame for the systemic dollar.

This reading has the advantage of coherence with previous historical episodes where the U.S. growth differential supported the dollar, notably 1995-2000 and 2014-2016. Its limit: it assumes execution of growth projections that remain uncertain. If 2026 U.S. growth were to disappoint, the argument would mechanically weaken.

Hypothesis 2: the fiscal risk premium via term premium

The second reading runs through the term premium on long Treasuries. According to the ACMTP10 series published by the New York Fed, the nominal term premium on 10-year Treasuries stands at approximately +0.8% on May 18, 2026 (0.72% on the monthly average, 0.96% on October 5, 2026). For context, this term premium was negative in 95 of the 105 months between January 2016 and September 2024, a phenomenon tied to structural demand for safe assets and to the Fed’s expanded-balance-sheet policy.

The reappearance of a positive and substantial term premium reflects a new risk premium demanded by investors to hold long U.S. debt. The proposed mechanism: the trajectory of federal debt, a federal budget deficit of 6.2% of GDP in fiscal 2024 and 5.8% in fiscal 2025 according to the OMB, imposes a compensation that short Treasuries no longer sufficiently offer, and which mechanically attracts foreign flows seeking to capture this term premium.

The BIS Quarterly Review of March 2026 does not adopt it: it describes a dollar that depreciated through most of the review period, a move reversed after the outbreak of the Middle East conflict. Its empirical footing is thin: the term premium only turned durably positive in October 2024, and DTWEXBGS dipped below 118 in July 2023 (14 sessions) as well as in 2026 (20 sessions). Its limit: the fiscal risk premium may pivot abruptly if markets lose confidence in the budget trajectory, the mechanism that today supports the dollar could tomorrow penalize it.

Hypothesis 3: defensive attractiveness and geopolitical fragmentation

The third reading places dollar persistence in the broader frame of geopolitical fragmentation. BRICS+ expanded in January 2024 with four new members (Egypt, Ethiopia, Iran, United Arab Emirates); Saudi Arabia, though invited, deferred its decision, and Argentina withdrew its application in December 2023. Tensions over Taiwan, Ukraine, Iran, and the Red Sea remain elevated. Western financial sanctions against Russia (freezing of Russian central bank reserves in February 2022) materialized a geopolitical risk on non-dollar FX reserves.

The proposed mechanism: in a more fragmented world, the dollar retains its default safe-asset status. According to IMF COFER data released on September 30, 2026, the dollar’s share of allocated FX reserves stands at 56.7% in Q2 2026, after a decade of gradual erosion, without the tipping point narratively announced. The confrontation between the de-dollarization narrative and observed reserve flows documents this resilience. More on this: the yellow metal gauged against the major currencies.

This reading has the advantage of direct observability: COFER flows, SWIFT volumes, and BIS statistics on international debt converge. Its limit: it assumes that defensive attractiveness will not reverse, an assumption the rapidity of monetary recompositions over the past ten years makes fragile.

The three hypotheses operate simultaneously

Current literature does not arbitrate between the three explanations. The most prudent reading acknowledges that they operate simultaneously, with relative weights that vary across sub-periods. The U.S. growth differential is documented and durable. The reappeared positive term premium is observable. The defensive attractiveness of the dollar is measurable.

The Eco3min analysis confines itself to posing the paradox and the three readings. The specifics are documented in our mapping of dollar shortage dynamics. It formulates no forecast for the remainder of the cycle. Since July 2025, DTWEXBGS has ranged between 117.4 and 121.9; it could hold there for several more quarters, or break out abruptly if one of the three factors reverses. EM transmission in the current cycle is itself a feedback factor: a regional EM crisis would modify safe-haven flows and reinforce the dollar in the short term before penalizing it via trade-balance deterioration.
