GBP/USD Whipsaws as Fed Hikes and BoE Holds Fire

The pound-dollar pair is caught between two diverging policy paths this week. The Federal Reserve's decision to lift rates to 3.75%-4.0% under Chair Kevin Warsh signals continued inflation-fighting resolve, a stance that typically strengthens the greenback and pressures GBP/USD lower.

Meanwhile, the Bank of England faces its own dilemma. UK inflation accelerated to 2.9% in August, yet slowing wage growth and a cooling labour market argue against the four additional hikes currently priced in by markets. This policy tension leaves Cable vulnerable to sharp repricing as traders reassess BoE tightening expectations.

With the Dow already down 600 points post-Fed, expect elevated volatility to spill into GBP/USD as risk sentiment sours and rate differentials shift.
