So, now we know. After much speculation and oblique references, Mark Carney has made it clear. The Bank of England has contingency plans whatever the outcome of the Scottish referendum.

This is what he said at the Inflation Report press conference this morning. The words are significant, and are his strongest on the issue of post-referendum planning.

"In terms of the financial stability questions - whatever happens in the vote, the Bank of England will continue to be the authority for financial stability for some period of time, certainly over the interim period."

In short, on the day after a referendum vote - if it's a yes to independence - nothing actually changes.

The Bank of England remains the lender of last resort to Scottish financial institutions and the guarantor of the currency during the period of negotiation over how Scotland and the rest of the United Kingdom separate.

We don't get a vote in this and we don't want a vote Mark Carney, Bank of England Governor

"We will look to discharge our responsibilities accordingly," Mr Carney continued.

"Uncertainty over the currency arrangements could raise financial stability issues. We will - as you would expect us to have - contingency plans for various possibilities."

Currency uncertainty

At this stage, Mr Carney is not going to tell anyone what they are.

"It's never good to talk about contingency plans in public other than to assure that we have contingency plans."

Sources in the financial world have told me that the plans are likely to focus on two issues - currency uncertainty and what is known as "deposit flight".

I asked the Governor directly about both, and specifically fears raised in a recent report by UBS that in the event of a yes vote on independence, customers of financial institutions based north of the border may decide to move their money southwards.

Some leading executives in the financial world are so concerned they had been hoping for a message of reassurance from the Bank.

Mr Carney suggested he was across the issue, which I have been told by senior banking figures is of concern to at least four major financial institutions which are based in Scotland.

"In terms of our responsibilities for financial stability - we have a wide range of tools," the Governor said in response to my question.

"We are not the only authority that has responsibility for financial stability - some of the powers that we have are held jointly with Her Majesty's Treasury - so we are not the sole decision maker in the process."

His views will be welcomed by campaigners for a "yes" vote who will play up the reassuring nature of the Governor's words.

And will spark a sigh of relief among those same Scottish-based major financial institutions I have been talking to which are fearful of customer reaction should there be a vote for independence.

There has been much debate - to put it mildly - on the currency relationship between Scotland and the rest of the United Kingdom in the event of a yes vote.

Will Scotland still use sterling? And if they do, how? The three main political parties in London have said they are against a "currency union".

The Scottish Government has made it clear it still wants to use sterling.

Alex Salmond and Alistair Darling have, ahem, rather different views on the matter.

You can read about their fiery exchanges in last week's STV debate here.

Financial stability

Mr Carney made it clear, once again, that whatever the outcome, the Bank is ready.

"We don't get a vote in this and we don't want a vote," he said of the referendum.

"The Bank has operational independence in the conduct of monetary policy - others, that is elected officials make decisions about our remit, our mandate.

"They will make the decisions about the currency - whether or not there is a currency union between Scotland and the rest of the United Kingdom in the event of a yes vote in the referendum.

"We do take note of the decisions of the three main Westminster parties to rule out a currency union, I will reiterate that we will implement whatever we're asked to implement.

"We have responsibilities for financial stability in the United Kingdom, we will continue to discharge those responsibilities until they change. We will continue to discharge those responsibilities regardless of the outcome of the vote on the 18th September."

The UK government has always insisted that it is not contingency planning for a yes vote. The Bank, it seems, is.
