"There is evidence that a material proportion of the 9% fall in sterling exchange rate since its peak in November could reflect referendum effects," the report said."There is evidence that a material proportion of the 9% fall in sterling exchange rate since its peak in November could reflect referendum effects," the report said.
What could happen to the value of sterling in the event of a vote to leave?
According Paul Hollingsworth, UK economist at Capital Economics, a vote for leave could trigger an immediate fall in the value of sterling.
However, he believes the severity of the fall would be determined by what the opinion polls say over the next few weeks.
"If we see more of shift towards Leave then clearly we could see some of that depreciation come before the vote than after it.
"However, if polls lean towards Remain and we still vote to leave then there would be more of shock factor, and that could hit the pound hard."
On balance, he believes that a vote to leave the EU would cause a 10%-20% fall in the pound.
What about in the following weeks and months?
Any recovery of sterling would depend on various factors. On the upside we could see the political rhetoric around Brexit change following the vote, and this might have a positive impact.
"I can't imagine the Prime Minister would say 'this result is all doom and gloom'," says Mr Hollingsworth.
"He would be positive, and say we are accepting this and will try and get the best from it.
"You would also see Mark Carney emphasising that the Bank of England were ready and able to act - so this might arrest any decline in currency."
That said, some have speculated David Cameron might have to step down in the result of a Brexit vote. This would result in a leadership contest and more political uncertainty which could affect sterling.
It is not clear how long the process of leaving the EU would take.
"The negotiations could take two years or much longer, so it could potentially weigh on the economy for a number of years," says Mr Hollingsworth.
"However, it may not be as bad as some have said, because during the negotiations we would still have free trade and the free movement of people… We wouldn't wake up on the 24th and find ourselves outside the EU."
How is the Bank of England preparing for the vote?
The Bank of England is unable to comment on the impact of a potential Brexit at the moment as it is in Purdah - the period leading up to an election during which government departments generally refrain from making new announcements.
However, it previously said it would inject money into the banking system to allay any shortages following the referendum result.
In terms of monetary policy following a potential Brexit vote, inflation could be a big challenge for the Bank.
"A sharp fall in sterling would push up inflation, as depreciation means the cost of imported goods would rise," says Mr Hollingsworth.
"Offsetting this though, the economy would probably weaken in the short term. So weighing up these two factors, we think that the Bank would probably end up leaving interest rates on hold for longer rather than cutting them."
