From my experience the banks would likely increase the [spread] of their variable-interest loans/financing for new applicants.

For example, RHB is now offering their ASBF at BR + 1.15% (without insurance) as their best rate today; however, just a few months ago, they were offering BR + 1.10%, and a few months before that BR + 1.00%. The banks do this to protect their margins (by increasing the spread for new applicants, as the OPR and BR are reduced)

You see, the effective interest rate for most banking products are lower now for everyone, but term loans stretch for up to 40 years (ASBF) and 35 years (mortgages); as the economy picks up the OPR would likely bounce and borrowers who apply for the financing when the OPR/BR are low will end up with higher [spread], long-term financing/loans; at least when compared to those who had their financing/loans a few months ago when the OPR was higher
