Dollar Weakens as ECB Signals Caution, U.S. Growth Disappoints

The dollar retreated against major currencies on Thursday as foreign exchange traders absorbed a cascade of signals from central banks and disappointing economic data. By late afternoon in New York, the euro had climbed nearly 0.7 percent to $1.1681, posting its largest single-day gain since May. Sterling advanced 0.4 percent to $1.3788. The dollar index, which tracks the currency against a basket of major peers, fell 0.6 percent to 93.3580.

Three forces converged to weaken the dollar. First came comments from European Central Bank President Christine Lagarde during a Thursday press conference. The ECB had maintained its existing policy stance—continuing bond purchases and keeping interest rates low—but traders interpreted Lagarde's remarks as lacking the forceful defense of that dovish position they had anticipated. Economists at Rabobank noted that Lagarde "failed to give enough pushback against market expectations of rate hikes next year," a shortfall that unsettled currency markets betting on continued monetary accommodation in Europe.

Second, the U.S. economy delivered weaker-than-expected growth. Gross domestic product expanded at just a 2 percent annualized rate in the third quarter, falling short of the 2.7 percent forecast that Reuters had polled from economists. The miss mattered partly because it suggested the American recovery was losing momentum at a moment when central banks globally were beginning to signal they might need to tighten policy to combat inflation.

Third, the currency markets themselves had grown unusually sensitive to central bank moves. The volatility had begun on Wednesday with hawkish comments from the Bank of Canada, continued Thursday with action by Australia's Reserve Bank—which declined to purchase a government bond as part of its stimulus program, signaling potential rate increases ahead—and now extended to the ECB's messaging. All of this unfolded before critical meetings next week by the U.S. Federal Reserve and the Bank of England, both of which traders expected might announce rate increases.

Mazen Issa, a senior currency strategist at TD Securities, observed that markets had become "very much triggered and sensitive to inflation worries and this notion that central banks are behind the curve." He added that month-end portfolio rebalancing by investment managers was amplifying the swings, as traders repositioned currency holdings across different economies.

The underlying tension reflected a fundamental shift in how traders were thinking about monetary policy. During the pandemic, central banks had cut rates and bought bonds to support their economies. Now, as inflation pressures mounted, those same institutions faced a choice: continue supporting recovery or raise rates to control prices. The yield curve—the relationship between short-term and long-term interest rates—had begun flattening, a pattern that suggested markets expected central banks would soon have to choose tightening over support. Eurozone yields rose sharply on Thursday as traders positioned for that shift.

The British pound gained ground against the dollar but lost 0.3 percent against the euro, caught between competing expectations about the Bank of England's next move. Australia's currency initially fell 0.5 percent after the Reserve Bank's statement but recovered to finish 0.3 percent higher, as traders digested the implications of earlier-than-expected rate increases. Bitcoin rose 3 percent to $60,040, suggesting some appetite for risk assets despite the currency market turbulence.

With the Federal Reserve and Bank of England set to meet in the coming week, currency traders were bracing for further volatility. The market's sensitivity to central bank signals suggested that the next phase of monetary policy divergence—different rates of tightening across major economies—would likely drive significant currency moves in the weeks ahead.
