Borrowing reversal takes shine off Trump success

The pound weakened against the euro and US dollar yesterday, following the widely predicted interest rate hold from the Bank of England. It has fallen further this morning to a five-week low against the euro, after news of more challenges for the chancellor.

Nevertheless, yesterday was a rare day where the prime minister was able to pat himself on the back, for a state visit from President Trump that came with billions of pounds of trade deals and the UK hailed as a tech superpower by global tech and AI leaders. Those investments included £22bn from Microsoft to build AI infrastructure, plus agreements to speed up nuclear reactor design.

For Kier Starmer yesterday also saw the first illegal migrant removal flight, and a challenger left-wing party led by Jeremy Corbyn appearing to implode.

But the challenges remain, and nowhere more than the economy. This morning we have heard that government borrowing soared to £18bn in August, the highest August borrowing for five years.

The pound has dipped sharply this morning in response to that, with GBP/USD down 0.75% since yesterday and GBP/EUR down 0.5%.

Other data out this morning gave a mixed picture for consumer mood. The GfK Consumer Confidence index fell, with the public telling researchers they were worried about potential tax rises in the Autumn Budget, which weighed more heavily than delight at the recent interest rate cut.

Retail sales were better than expected, but this was largely credited to the weather, with clothing stores perked up by the early arrival of autumnal weather.

So where does all this leave the value of sterling? Against the euro it is 3.5% down on a year ago, and seemingly on a new downswing after a month of relative stability.

Against the US dollar, the reversal of the past three days comes on the back of growth and only returns GBP/USD to where it was a month ago, still more than 2% up on last year.

GBP: Steady pound’s losses minimised

Although sterling weakened yesterday against almost all currency pairs, we have ended a period of high impact data relatively unscathed, with declines of less than 0.5%. It’s not all over yet: on Tuesday we have the purchasing managers index (PMI).

EUR: Euro weakens against dollar

It was a rare reversal for the single currency against the dollar yesterday, dropping close to three-quarters of a cent. Or perhaps more of a correction, as EUR/USD remains up on the week and month. Next week will be all about business optimism (or pessimism) with PMI on Tuesday and Germany’s Ifo Business Climate on Wednesday.

USD: Dollar carries all before it

The dollar strengthened against the vast majority of currency pairs yesterday, including almost 1% against the pound. After a busy week on the currency markets the week splutters to an end with not much happening data-wise, but could there be a correction from yesterday’s strength, or is it just the start of something?
