A bank with an outstanding borrowing of $70m at 0.75% above LIBOR has the alternative of rolling over the existing loan at the same rate or increasing it to $110m at 0.85% above LIBOR. The funds are currently committed to credit lines yielding 1.2% above LIBOR but the bank reckons that if it lowered it's spread to existing customers to 1.1% it could place the extra funds. Should it?
