Dollar-Yen Surges Above 158 as US Economic Data Exceeds Expectations

The dollar-yen pair rose to its highest level in New York trading on the 23rd, closing above 158. The pair's value increased from 157.76 to 158.40, driven by strong U.S. economic data and hawkish Federal Reserve remarks.

S&P Global's flash estimate for the September manufacturing Purchasing Managers' Index (PMI) in the United States came in at 57.0, exceeding the market consensus of 53.7 and marking a four-year high. The services PMI reached 58.7, while the composite PMI hit 58.4, both above forecasts.

Federal Reserve Governor Barr mentioned that additional rate hikes may be necessary to curb inflation, triggering a sharp rise in long-term U.S. Treasury yields and accelerating dollar buying. A lackluster 5-year Treasury auction on the same day further fueled bond selling and yield increases.

The yen briefly fell to 158.40 but stabilized near the mid-158 range due to caution over potential intervention by Japanese monetary authorities. Intervention concerns led to yen buybacks, while a rebound in crude oil prices reinforced inflation resurgence concerns, pushing up the dollar and bond yields.
