Because there is a legal obligation to repay them - thanks to the previous govt signing up to them - and it will cost us somewhere in the region of €4bn a year for the next 10 years to pay them back.
That's €4bn that has to come out of service and in tax rises that could be better spent investing in the economy to stimulate growth.
If the govt can get that spread over a longer term at lower interest, it could reduce the cost to €1bn to €1.5bn which eases the burden on taxpayers.
If we are stuck with this deal as signed by FF, it will kill us sooner or later.
My own view is that €31bn needs to be parked somewhere for a decade or so until the economy has recovered and we will be in a better position to pay it off over a long period of decades rather than 10 years.
Don't think it's as easy as that - as I understand it would leave a massive hole in ICB balance sheet which would then fall onto the ECB balance sheet and the Gnomes of Frankfurt won't allow that to happen. Those promissory notes are legal IOUs and the ECB is determined to enforce their repayment in full, as far as I understand it.
But as I said, I don't pretend to understand the whole three-card trick and I'm just saying what was explained to me and my limited understanding of it is limited.
Anyways it looks as if FG has given up on negotiating the promissory notes as well
