LONDON - Starling Bank's pre-tax profit rose to 301.1 million pounds ($383.69 million) in the year to March 31, a nearly 55% jump on the previous year, in the third year of profitability for the British digital bank.

John Mountain, the bank's interim CEO, said that higher interest rates "undoubtedly provided a strong tailwind", although the number of customer accounts also rose to 4.2 million from 3.6 million the year before.
