Conclusions

Overall, despite some cyclical headwinds, including increasing global geopolitical fragmentations and RBI rate cuts transmissions, several structural potential domestic tailwinds should support the financial sector in 2026-27. And the banking sector is well capitalised to support the Indian growth story. In India, generally, RBI or even governments do not press banks too much for rate cut transmissions, especially for PSBs and also do not encourage indiscriminate & irresponsible lending. Thus, the overall impact of RBI rate cut transmissions on NIM may not be too much going forward.
