London’s markets closed in the red after buoyant service sector figures and strong US jobs data rekindled inflation concerns.

A slowdown in US jobless claims was cautiously welcomed by Wall Street traders who were worried improvement in the economy would see central banks ease current support measures and potentially raise inflation rates.

In London, traders were unnerved by inflation concerns and a poor showing by travel firms but welcomed their own positive service sector data, which revealed the strongest growth in output for 24 years.

The FTSE 100 closed 43.65 points lower, or 0.61%, at 7,064.35 on Thursday.

Chris Beauchamp, chief market analyst at IG, said: “Indices have looked wobbly for a few days, with the swift reversal from Tuesday’s peak showing that something was amiss with global risk appetite. Today has seen those concerns validated to an extent, with some notable losses for tech and other US growth stocks, even if losses are more contained elsewhere.”

The Dow Jones and S&P 500 both opened marginally lower as a result, with the tech heavy Nasdaq index particularly shaken, dropping almost 1%.

In mainland Europe, the knock-on from Wall Street resulted in cautious trading but German stocks remained in positive territory amid positive Eurozone economic data. The German Dax increased by 0.19% and the French Cac moved 0.21% lower. Meanwhile, sterling dipped slightly against the US dollar after the greenback was bolstered by the strong APD jobs reading.

The pound decreased by 0.09% versus the US dollar to 1.410 and increased by 0.02% against the euro to 1.163.
