Asian stocks ease as tech rally cools and oil edges higher

Asian equities slipped from recent highs in early trade on Tuesday, with MSCI’s regional benchmark down 0.2%, as investors weighed higher oil prices, US Iran peace talks and a pause in the AI driven technology rally.

US equity futures also softened after the S&P 500 fell 0.4% overnight, pressured by megacap tech losses and rising Treasury yields, while Brent crude traded above $78 a barrel following a temporary US waiver on Iranian oil exports.
