Asian stocks set to climb Thursday after Wall Street gains driven by US-Iran talks optimism. Nvidia shares whipsawed despite beating sales forecasts of $91 billion versus $87 billion estimates. The chipmaker increased quarterly dividend to 25 cents and announced $80 billion in stock repurchases. Samsung Electronics rose 5% after reaching a last-minute labor deal to avoid a strike.

President Trump said US-Iran talks are in "final stages," pushing expectations for resumed energy flows through the Strait of Hormuz. This optimism helped Brent crude fall more than 5% to about $105 per barrel. Investors scaled back bets on interest-rate cuts as inflation concerns receded. Treasuries rallied across the curve while the dollar edged lower and gold rose.

Asian markets rebounded after four days of losses as bond yields eased. Traders tempered bets on Federal Reserve rate hikes by year-end, though still anticipate a next move will be a hike rather than cuts. "I'd love to believe this, but let's face it: How many times have we heard this before?" said Win Thin, chief economist at Bank of Nassau 1982, reflecting skepticism about Iran talks progress. The market remains cautious despite recent gains.
