US CPI Test Looms Over Cable: GBP/USD Hovers at 1.3390

GBP/USD traded near 1.3390 during early European hours Wednesday. Traders positioned ahead of the May US Consumer Price Index report, due at 8:30 a.m. ET from the Bureau of Labor Statistics. The pair has held a narrow range in recent sessions. Activity was subdued, with participants avoiding large bets before the data.

The May CPI print carries extra weight after a string of mixed economic data left the Federal Reserve's rate path unclear. A hotter reading could reinforce the case for holding rates through the summer. A softer number would revive expectations for a September cut. The dollar has tracked those rate expectations closely. That makes the CPI release a potential pivot point for GBP/USD and broader currency markets.

The cautious positioning echoes the mood before last month's CPI release, as covered in AlphaScala's previous analysis. Sterling has gained ground against the dollar since April. It was helped by a repricing of Fed rate bets and resilience in the UK economy. The Bank of England is seen cutting rates later than previously forecast, a shift that has narrowed the policy gap with the Fed. That relative advantage has supported GBP/USD above the 1.31 handle, with the pair now testing the upper end of its recent range. Resistance sits near 1.3400, a level that has capped gains this month. Support is around 1.3330, the 50-day moving average.
