Yen Surges as Fed and BOJ Diverge in Monetary Policies

The yen rose against the dollar, hitting a three-week high, due to differing monetary policy approaches by the U.S. Federal Reserve and the Bank of Japan. The dollar also neared multi-month lows against the euro and sterling. Market responses were driven by comments from central bank leaders in the U.S., Japan, and U.K.

The yen surged to a three-week high against the dollar on Monday, propelled by Federal Reserve Chair Jerome Powell's dovish stance, which stood in stark contrast to Bank of Japan chief Kazuo Ueda’s hawkish tone.

The U.S. dollar hovered near its 13-month low against the euro and sagged closer to its weakest levels since March 2022 against sterling. Bank of England head Andrew Bailey indicated that it was 'too early to declare victory' over inflation, signaling a less aggressive stance on interest rate cuts compared to the Fed. Early Monday, the dollar fell as much as 0.59% to 143.56 yen, and last traded down 0.25%.

Sterling remained steady at $1.3215, after peaking to $1.32295 on Friday, its highest in 17 months. Although Fed officials had increasingly turned dovish leading up to the annual Jackson Hole symposium, Powell's keynote speech used decisively stronger language, noted Tapas Strickland, head of market economics at National Australia Bank. Strickland highlighted that Powell's absence of cautious 'gradualism' language markedly excited markets.

In Asia, BOJ’s Ueda, speaking in parliamentary testimony on Friday, adhered to the stance of the BOJ requiring further policy rate adjustments. Many market participants had expected Ueda to strike a less hawkish note, especially amid criticism over July’s rate hike, which sparked rapid unwinding of bearish yen bets and aggressive sell-off of Japanese stocks. Meanwhile, the dollar index, which measures the currency against six major peers, slumped at 100.64, close to the 13-month low of 100.60 achieved last week.

Despite hints from ECB policymakers for another rate cut on Sept. 12, the euro remained stable at $1.1190. Traders overwhelmingly anticipate the Fed will begin its loosening campaign on Sept. 18, with a 36.5% chance of a 50-basis point reduction, up from 25% odds the week prior. The Australian dollar eased slightly to $0.6790, near its peak since July 11, while the Chinese yuan marginally increased to 7.1130 per dollar in offshore trading. Bitcoin rose 0.9% to $64,271.60.
