SynopsisGlobal stock markets are experiencing a cautious rebound following a tech sell-off, fueled by AI spending and hawkish US interest rate signals. While South Korea's Kospi shows volatility, AI giants are tapping bond markets for capital. Despite inflation fears, retreating oil prices and a stabilizing US-Iran deal may ease concerns.AgenciesRepresentative image Stock markets have made a hesitant recovery from a technology sell-off earlier this week, amid debt-funded AI spending as the US Fed turns hawkish over interest rates.

Interest rates are a concern for asset price bubbles. But they need to harden to threaten a foundational technology such as AI.Concentration of investor interest in AI infrastructure poses some challenges to Indian equities, which do not offer any defined theme.
