Dollar Surges on Hawkish Fed Signals, Posts Best Weekly Gain in Three Months

The U.S. dollar posted its largest weekly gain in over three months after the Federal Reserve signaled a commitment to further interest rate hikes, reinforcing the currency's strength amid a resilient American economy.

Fed's Hawkish Stance Fuels Rally

The Bloomberg Dollar Spot Index climbed 1.1% this week, marking its most significant weekly advance in more than three months. The move followed the U.S. central bank's indication that it would continue to tighten monetary policy to combat inflation.

According to analysts at firms including JPMorgan Chase & Co., Standard Chartered Plc, and Brown Brothers Harriman, the Fed's clear forward guidance has removed a key element of uncertainty that had previously restrained the dollar's ascent. The dollar's rally was slightly tempered late in the week after the Japanese yen recovered some ground on reports that the Bank of Japan conducted a rate check, a move often seen as a precursor to currency market intervention.

Technicals and Positioning

From a technical perspective, the Bloomberg Dollar Spot Index ended the week just above its 200-day moving average, a critical long-term trend indicator. Historical patterns in March and June showed that decisive breaks above this level were followed by sustained upward momentum.

The Fed's hawkish turn appears to have caught some market participants off guard. Prior to the central bank's announcement, speculative investors had been reducing their bullish bets on the dollar. Data from the Commodity Futures Trading Commission (CFTC) showed that, as of September 15, net-long dollar positions among non-commercial traders had fallen for seven straight weeks.

Divided Outlook on Dollar's Peak

Despite the strong weekly performance, strategists are divided on whether the dollar can reach new highs for the year. Elias Haddad, a global market strategist at Brown Brothers Harriman, noted that other major central banks are also tightening policy, which could limit the scope for further monetary policy divergence and cap the dollar's gains.

However, the relative outperformance of the U.S. economy remains a powerful tailwind. Haddad pointed to upcoming S&P Global PMI data, which is expected to show U.S. economic growth outpacing that of the Eurozone, the U.K., and Japan. Pat Locke, a foreign exchange analyst at JPMorgan, argued that the dollar was undervalued by 2% to 4% before the Fed's meeting, based on interest rate differentials. He suggested the currency is now in a "catch-up" phase, particularly against lower-yielding currencies.

Steve Englander, head of North America macro strategy at Standard Chartered, believes the Fed's actions have made shorting the dollar a riskier proposition. He projects that a potential rise in the 10-year U.S. Treasury yield to 5.5% over the next year could clear a path for further dollar appreciation.
