Investor sentiment was also buoyed after minutes from the Fed’s mid-June meeting showed that most of its officials expect rate cuts will be appropriate later this year. The minutes showed that policymakers believe price shocks from new US tariffs will be “temporary or modest”.

Meanwhile, US President Donald Trump released a new batch of tariff letters on Wednesday, with duties set to take effect 1 August unless agreements are reached. He also said the US will impose a 50% tariff on imports from Brazil, which would represent one of the highest rates announced to date.
