The Fiscal Commission Working Group, a panel of experts established by the Scottish Government, was asked by ministers to plan for how Scotland would become independent if there is a "yes" vote in the 2014 referendum.
They concluded that "it would be in Scotland's interests to retain Sterling immediately post-independence".
The report, published on Monday, said that Scotland's economy was "strong enough and sufficiently aligned with the rest of the UK that a separate currency would not be necessary.
"It is also the case that, post independence, this would benefit the rest of the UK to maintain a key trading partner as nearly 10% of the existing UK economy Scotland would remain one of the largest trading partners of the UK economy," their report said.
"There would be particular advantages for the UK in areas such as energy and financial services."
Experts on the panel include two Nobel prize-winning economists: Joseph Stiglitz and Sir Jim Mirrlees. (Daily Telegraph)
