TLDR: Four US banks, including Regions Financial, Fifth Third Bancorp, State Street, and Comerica, have warned of lower interest income in 2024 due to high deposit costs. The banks have been profiting from high interest rates charged on loans for over a year. However, they are now facing challenges such as weaker loan growth and potentially tougher capital rules. The Federal Reserve’s rate cuts later this year may ease some pressure on banks to raise deposit costs further. Huntington Bancshares has offered hope, forecasting a 2% rise or fall in net interest income (NII) compared to 2023 levels. The bank expects its NII to trough in Q1 and expand throughout the year. The forecasted average loan growth is 3-5%.
