The amount of money held by banks and financial institutions on the Island fell by £360 million at the end of last year.
According to the Financial Services Authority, deposits with Isle of Man licensee offices fell by 0.85 per cent to £41.82 billion between September and December.
It wasn't all bad news, however, as the year on year figures were up by just over 1 per cent.
At the end of December, deposits had risen by £420 million compared to the previous year's figure.
