Story summary

The FTSE 100 closed almost unchanged on Wednesday despite initially reacting positively to strong US economic data. The index ended slightly down at 10,705.26 points after earlier gains were offset by a defiant speech from Iran’s President Masoud Pezeshkian during his address at the United Nations General Assembly in New York. In Europe, the CAC 40 in Paris and DAX 40 in Frankfurt also declined slightly, down 0.4% and 0.7%, respectively.

The initial boost to UK markets came from a report indicating that US business activity growth had accelerated for four consecutive months, reaching its fastest pace since May 2015 according to the S&P Global “flash” PMI composite output index at 58.4 in September, up from August’s 56.0, surpassing expectations of 55.3. However, this positive sentiment was soon overshadowed by concerns over escalating tensions with Iran following President Pezeshkian's assertive speech at the UN.
