Dollar posts best quarterly gain of 2026, rattling global currencies

The U.S. dollar closed out the second quarter of 2026 as the foreign exchange market's standout winner, gaining 1.4% against a basket of major currencies, according to Reuters. The greenback's advance — buoyed by a hawkish Federal Reserve pivot and resilient economic data — has sent shockwaves through Asian currency markets and prompted major banks to turn decisively bullish on the dollar.reuters

Fed Hike Expectations Fuel the Rally

The dollar index climbed to a 13-month high near 101.80 in late June as markets repriced the Federal Reserve's path from rate cuts to potential hikes, CNBC reported. CME FedWatch data showed traders pricing roughly a 32% chance of a rate increase at the Fed's July meeting and approximately 66% by September. The shift followed the Fed's June policy meeting, where officials signaled a heightened focus on inflation even as the broader economy maintained 2.1% annualized GDP growth in the first quarter.cnbc+1

HSBC ↗ 1.01% warned on Monday that a "more explosive period of USD strength" could emerge as one of the biggest pain trades of the second half, according to Bloomberg. "A stronger USD would be painful, but we see the 'pain trade' in the FX market taking the form of a more explosive period of USD strength," the bank wrote, cautioning that aggressive Fed tightening signals could trigger a rapid ascent in the currency. JPMorgan ↗ 0.12% has also maintained a bullish dollar outlook, favoring long positions particularly against the Canadian dollar.bloomberg+2

Asian Currencies Bear the Brunt

The South Korean won broke past the 1,550-per-dollar level in intraday trading before closing Monday at 1,549.4 won — its weakest weekly close since the 2009 global financial crisis, according to the Seoul Economic Daily. The currency has been battered by a triple blow: the stronger dollar, sustained net selling of Korean equities by foreign investors, and an exceptionally weak yen. The Kospi has tumbled alongside the currency decline.sedaily

The Indian rupee also weakened, trading around 94.66 per dollar on Tuesday. The Reserve Bank of India held its repo rate at 5.25% at its June meeting and announced emergency measures to shore up the rupee, including subsidized hedging for bank deposits and tax exemptions for foreign investors in government securities — moves that could attract up to $40 billion in inflows, according to MUFG Research.alanchand+2

Outlook Remains Dollar-Positive

Morgan Stanley ↗ 0.98% had earlier forecast the dollar index would fall to 94 by mid-2026, but those projections have been overtaken by events. The combination of persistent inflation, geopolitical tensions in the Middle East, and U.S. economic resilience has instead pushed the greenback higher for what Reuters described as its strongest quarterly showing of the year. HSBC expects the dollar to strengthen gradually through the first half of 2027, with the risk of an acceleration if the Fed acts "more aggressively than market pricing".morganstanley+3
