The interest rate at which banks lend money to each other has fallen, according to British Bankers' Association data.

The Libor rate for borrowing sterling for three months fell to 4.49% from 5.56% on Friday after the Bank of England rate cut was announced.

Libor is fixed once a day and sets the rate of $360 trillion (£210 trillion) worth of financial products worldwide, ranging from mortgage rates to car loans.
