A European bank tax to pay for dismantling bust banks
The new chancellor of the exchequer and Michel Barnier, the European Union's commissioner for the internal market, are trying to hit it off.
Which is why when Mr Barnier announces later today that he believes that all European Union countries should impose a near-identical new tax on banks, the Treasury is likely to point out that George Osborne too is in favour of such a levy: in fact, the coalition has said there may be a case for two new taxes on banks, one on what they borrow and one on their profits.
But there'll be no disguising that Mr Barnier and Mr Osborne could not be further apart on what happens to the proceeds of such a tax.
Mr Osborne's view is that the British government should be free to do what it likes with the revenues.
By contrast Mr Barnier will argue that the wonga should go into national "resolution" funds, whose purpose would be to pay for the orderly dismantling of banks that run into difficulties.
In other words, the proceeds of the tax would be a form of insurance to minimise any future bill for taxpayers, were we to see any kind of repeat of the great banking crisis of 2008 (that suddenly seems a topical anxiety).
Mr Barnier will try to allay Mr Osborne's main concern, which is that banks might be encouraged to redouble their lending and investing follies if they knew that a bailout fund existed to rescue them in the event that their bets were to go pear-shaped.
The commissioner will say that the resolution funds would be used only to provide the kind of temporary finance required to lubricate the break up of big banks - but the money would not be deployed to reduce losses for shareholders and creditors (though retail depositors would remain a protected species).
