Last month, Santander announced it would cut the interest rate on its popular 123 current account from 3% AER (variable) to a flat 1.50% AER on any balance up to £20,000 from 1 November 2016.

This was a hammer blow to its four million account holders but the news wasn’t entirely unexpected following its confirmation that it would review accounts in light of the Bank of England’s decision to cut interest rates to 0.25%.

Ahead of the rate cut, many Santander customers may be thinking about ditching the bank and switching to a competitor.

But in the last few days Lloyds and TSB have also announced cuts to credit interest rates, while Halifax said it would be trimming its monthly reward payments from £5 to £3 from 1 February 2017.

The question now for Santander 123 customers is whether to stick or twist.
