BlackRock, the world's largest asset manager, expects the artificial intelligence boom to continue to boost U.S. stocks and support broader economic growth next year, although rising U.S. debt levels could threaten its optimistic forecast for 2025. The agency said innovations in artificial intelligence technology could benefit U.S. stocks more than European stocks. The agency said that while U.S. economic growth may cool slightly next year, the Federal Reserve is unlikely to cut interest rates significantly because inflation remains sticky and above the central bank's target. The agency does not expect interest rates to fall below 4% from the current 4.5%-4.75%. Continued price pressures caused by factors such as geopolitical divisions and infrastructure spending could weigh on bond markets.
