Strong consumer inflation figures provided support for the British Pound (GBP) on Wednesday, although increased public borrowing offset their positive impact. After briefly wavering in early European trading, Sterling resumed its advance against the US Dollar (USD). With GBP/USD having climbed nearly 2% from last week’s lows, buyers are now testing resistance around 1.3400.

September inflation exceeded expectations as higher energy prices drove an acceleration in price growth, according to UK Consumer Price Index (CPI) data published earlier in the day. The release has reinforced expectations that the Bank of England will finally raise interest rates at its 4 November meeting.
Sterling initially struggled to gain traction after the release. Published simultaneously, the UK’s Public Sector Net Borrowing figures showed that government debt rose in September at its fastest pace in more than five years, largely because of debt interest. With Chancellor John Healey preparing the budget for release next week, the borrowing data may have revived longstanding concerns over the UK’s public finances.
Having confirmed a break above the preceding two weeks’ horizontal range earlier this week, GBP/USD retains a positive bullish bias at 1.3389. On the 4-hour chart, the Relative Strength Index (14) stands at 69.14, just short of overbought territory. Meanwhile, the Moving Average Convergence Divergence (MACD) histogram is slightly positive. Together, these indicators point to firm upward momentum, albeit one that is becoming increasingly stretched in the short term.
If 1.3400 gives way, buyers will target the lows of 13 August and 3 September around 1.3470. This area also marks the 61.8% Fibonacci retracement of the August-October decline. Beyond that, the next level would be the 9 September high near 1.3670.
Around 1.3300, the lows recorded on Monday and Tuesday coincide with the upper boundary of the previous two weeks’ channel, providing immediate support. A decisive break below this level would restore bearish control and turn attention back to the year-to-date lows near 1.3140.
