Pound Sold Off Sharply as US Survey Data Outperforms UK's

Lead: Flash PMI surveys released Wednesday showed US business activity growing at its fastest pace since July 2021, while UK business activity slowed, a stark contrast that triggered a sharp sell-off in the pound against the dollar.

**Data Divergence Pressures Sterling**

The flash PMI data released that day served as a direct catalyst for market moves. In the US, the pace of business activity expansion accelerated notably, reflecting stronger-than-expected economic resilience. In contrast, UK business activity indicators for the same period showed signs of weakness, with growth momentum fading. This short-term divergence in economic performance was quickly priced into the foreign exchange market, with the pound facing concentrated selling pressure against the dollar.

**Monetary Policy Expectation Gap Amplifies Volatility**

The gap in economic data directly reshaped market expectations for the policy paths of the two major central banks. The relative strength of the US economy reinforced the narrative that the Federal Reserve would keep interest rates higher for longer, boosting the dollar's appeal. Meanwhile, signs of slowing UK growth raised doubts in the market about the Bank of England's future policy room. According to market reports, the yield advantage of US Treasuries over UK gilts widened accordingly, further narrowing the pound's rate differential advantage, leading to sustained capital outflows from sterling during trading.

**Sterling Faces Key Support Test in Near Term**

Under the data shock, the pound's rebound momentum above the 1.3360–1.3365 area against the dollar has proven insufficient, and the exchange rate needs to reclaim and hold key resistance levels to improve its short-term technical outlook. Market focus has now shifted to subsequent economic indicators to verify whether the growth divergence will persist. If US data continues to strengthen, the pound could face further downward pressure.
