Dollar Momentum Index
The world's reserve currency as a macro signal.
DXMI measures the momentum and regime of the US dollar across major currency pairs, with emphasis on the dollar's role as a global liquidity barometer rather than a simple FX trade.
The Dollar Momentum Index (DXMI) measures the strength and directionality of the US dollar relative to a trade-weighted basket of major currencies — EUR, JPY, GBP, CAD, AUD, and CHF. Importantly, DXMI focuses on momentum (trend strength and persistence) rather than simply the dollar level, because sustained dollar strength has different macro implications than a brief spike. High DXMI indicates a strong, trending dollar; low DXMI indicates a weak or range-bound dollar.
The US dollar is the world's primary reserve currency and the denomination for most global commodity prices and trade finance. A strong dollar tightens global financial conditions: it makes dollar-denominated debt more expensive for foreign borrowers, compresses commodity prices (which are priced in USD), and reduces the earnings of US multinationals when foreign revenues are translated back to dollars. High DXMI periods historically correlate with stress in emerging markets, commodity weakness, and tighter global credit conditions.
Dollar strength and global liquidity are inversely related. When the dollar strengthens, dollar-denominated capital flows back to the US, draining liquidity from global markets. Emerging market countries with dollar-denominated debt face rising refinancing costs. Commodity-exporting economies see their export revenues compress in local currency terms. This is why sustained high DXMI readings are often associated with EM credit stress, commodity price weakness, and risk-off conditions in global equities.
DXMI above 65 indicates strong dollar momentum that has historically been associated with broad global tightening. Readings above 80 correspond to dollar regimes comparable to 2014-2015 (EM crisis), 2018 (EM stress), and 2022 (global monetary tightening). DXMI below 35 indicates a weakening dollar — historically correlated with risk-on conditions, commodity bull markets, and EM outperformance.
