Global stocks rallied on Friday as robust results from Amazon and Microsoft reassured investors to return to AI trade, while currency traders stayed alert to intervention a day after Japanese authorities likely stepped in to prop up the yen. The dollar was last up 0.35 per cent at 160.09 yen after the Bank of Japan held interest rates steady. Microsoft's earnings on Wednesday forecast generating cash throughout fiscal 2027, and Amazon followed with its strongest cloud growth in more than four years. In Europe, the STOXX 600 index hit a record high and was poised for its fourth consecutive month of gains. Futures tracking the tech-heavy Nasdaq 100 index rose 1.05 per cent, while S&P 500 and Dow futures rose 0.32 per cent and 0.45 per cent, respectively. South Korea's KOSPI leapt 17.91 per cent, mounting a record comeback after heavy losses earlier this week, though it remains about 30 per cent off its all-time high. The MSCI All Country World Price index gained 0.81 per cent and was on track to snap a two-week losing streak, though it will still end the month with losses of 0.40 per cent should current levels hold. The yen had gained on Thursday when Japan conducted yen-buying, dollar-selling intervention, a market source said. The BOJ kept interest rates unchanged on Friday but signalled its resolve to push up borrowing costs.
