US Dollar, USD, 78/100, Bullish: Fed rate hike lifts greenback above 100.00 as first increase in three years reshapes rate differentials across majors.
Learn why the Federal Reserve's hawkish pivot triggered a dollar rally and which currency pairs face the sharpest repricing ahead.
What Happened
The US Federal Reserve delivered its first rate increase in three years on Wednesday, lifting the benchmark fed funds rate and signalling more hikes to come. According to market reports, the dollar soared immediately as this policy shift fundamentally altered the interest rate landscape: the Fed's new rate now exceeds the Bank of England's, eroding the Pound's relative yield advantage, and matches the ECB's rate, eliminating any prior Euro advantage. The greenback index broke above the psychologically significant 100.00 level as traders repriced their forex market analysis to reflect a tighter monetary stance from the world's largest economy.
Beyond the headline rate move, forward guidance proved equally influential. Fed dot plot commentary and remarks from officials like Warsh rattled markets more than the immediate hike itself, according to reporting from ForexLive, signalling the central bank's hawkish tilt may persist. Simultaneously, equity indices tumbled on the news: stocks fell sharply as the Nasdaq and Dow both retreated, with Wells Fargo cutting its S&P 500 target on valuation concerns even before the announcement. This combination of tighter monetary policy and equity weakness created a perfect storm for currency strength in the dollar, which typically benefits when real yields rise and risk appetite falters. The dollar's upside move was neither a surprise nor a blip: it reflected genuine repricing of rate differentials and forward rate expectations across the entire FX complex.

Market Reaction
The forex market responded with a stark bifurcation: USD strength crushed almost every major counterpart, while the widest sentiment gap emerged between the dollar's bullish 78/100 reading and GBP/USD's bearish setup at 28/100. The Pound tumbled to below its long-run average as the Fed's rate now exceeds the BoE's official bank rate, an exchange rate dynamic that pressures sterling hard. EUR/USD also sank as the Fed matched ECB rate levels, stripping away any remaining yield cushion that had supported the euro.
Commodity-linked and risk-sensitive currencies fared worst: the Australian Dollar and Canadian Dollar both slipped to summer lows as the dollar's rally directly pressured USD/CAD higher and AUD into technical weakness. The Japanese Yen, which had rallied earlier on safe-haven flows, gave back those gains as the wider rate gap made the carry trade more attractive away from yen funding. New Zealand's kiwi briefly popped on better-than-expected Q2 GDP growth of 0.2%, but even that positive surprise proved insufficient to override the Fed's gravitational pull, as NZD sank toward July lows by session's end. Only the Swiss Franc managed neutral footing on safe-haven demand offsetting dollar strength, keeping EUR/CHF at modest support.
What's Driving the Move
Three key threads run through the bullish US Dollar story:
- Federal Reserve raised rates for the first time in three years and signalled additional hikes ahead, lifting the US Dollar Index above 100.00 and widening rate differentials against sterling and the euro.
- Forward guidance from Fed officials, particularly hawkish dot plot signals, rattled equity markets more than the rate decision itself, driving safe-haven flows into the dollar and away from risk assets.
- Equity weakness across major indices, including a 600-point Dow decline and Wells Fargo's downward S&P 500 revision, reinforced dollar demand as investors repriced both growth and rate expectations.
