Royal Bank of Scotland will raid its bonus pool to help pay for its Libor fixing fines after the Chancellor made it clear the penalties must not hurt the taxpayer.
It will recoup around £300m from the 2012 pool and claw-backs of awards from previous years after Mr Osborne said fines should be paid for by the bankers only.
RBS said around 1,500 investment bankers will bear the brunt of the bonus cuts and claw-backs.
Mr Osborne's intervention came after fears the Bill would see the taxpayer suffer, given that it remains 81% state-owned after the bank's £45bn bailout in 2008.
Under the settlement, £87.5m of the £391m total will go to the Financial Services Authority (FSA), with the remaining sum split between the US Department of Justice and the US Commodity Futures Trading Commission (CFTC).
While most fines will go to the US authorities, some will end up back in the UK public purse, as banking sector penalties made by the FSA are now paid to the Treasury. A welcome change in the rules made by Mr Osborne.
Previously the FSA, funded by annual bank levies, would use fines to reduce levies for other banks. Only money left after FSA investigation and enforcement costs will go to the Exchequer.
Following the Barclays fine last year, the Treasury donated £35m from bank fines to causes that support Britain's Armed Forces community, but all subsequent cash goes directly to the Treasury.
Here are some extracts released by the US CFTC, which investigated the manipulation:
