Repo-linked loans can transmit policy changes faster, which is helpful when rates fall and painful when they rise. MCLR-linked loans may move with a different lag. Neither behaviour is automatically superior; the borrower needs enough cash-flow resilience for the reset pattern.
If you are considering switching, obtain historical reset notices from your current loan and compare how quickly past benchmark changes reached your rate. Then ask the new lender for its reset frequency and spread. This gives you evidence rather than relying on a salesperson’s claim that one benchmark is always cheaper.
Keep an eye on the remaining loan term after every reset. If the lender extends tenure, decide whether to accept it, increase EMI or make a part-payment. Small interventions early in the loan can prevent a large amount of extra interest later.
