London's FTSE 100 closed about 0.6% up at 9,178 on Wednesday, bouncing back from its biggest daily decline since April in the previous session. The drop came after a global bond selloff pushed the UK’s 30-year bond yield to its highest level since May 1998. Meanwhile, Chancellor Rachel Reeves set the date for her highly anticipated Budget amid speculation over potential tax increases and market concerns about the UK’s public finances. On the domestic data front, a PMI survey showed that activity in the UK's services sector accelerated more than previously thought in August, with growth hitting a 16-month high. On the corporate side, precious metals companies Fresnillo (8.1%) and Endeavour (3.6%) saw strong gains, driven by gold hitting a record high. Copper miner Antofagasta was also among the top performers, rising 3.1%. However, Pearson was the biggest laggard, dropping 3.6% after Goldman Sachs trimmed its price target to 1490p.
