Governor of the Bank of England Mark Carney will meet with the Treasury Select Committee to answer questions on the "economics of currency unions" amid debate over the possible implications of a Scottish vote for independence.
Chancellor George Osborne has already ruled out a currency union between an independent Scotland and the rest of the UK.
First Minister Alex Salmond's Scottish Government wants to create a "sterling zone" with the rest of the UK if there is a Yes vote in the break-away referendum.
Mr Carney said in a speech in January that an effective currency union would force a newly-independent Scotland to hand over some national sovereignty in a similar way to how this is done in the eurozone.
"Any arrangement to retain sterling in an independent Scotland would need to be negotiated between the Westminster and Scottish parliaments," he said. "The Bank of England would implement whatever monetary arrangements were put in place."
