Bank NIMs Under Pressure After December 2025 Repo Cut
Why in the news
After the December 2025 repo cut, banks face narrower margins because loan rates reset faster than deposit rates.
About NIM
- Net Interest Margin shows how profitably a bank earns from lending and investing against what it pays for funds.
- Formula: (Interest Earned − Interest Expended) ÷ Average Interest-Earning Assets × 100.
| Term | Meaning |
|---|---|
| Interest earned | Income from loans, advances, government securities, investments |
| Interest expended | Cost of deposits, borrowings and other funds |
| Interest-earning assets | Loans, advances and investments that yield interest |
Why NIMs matter
- Signals profitability: wider gap between lending income and funding cost.
- Reflects handling of interest rate risk and asset-liability mix.
- Stronger NIMs usually mean higher NII and profit growth.
