How to borrow £200bn
What I expect the Debt Management Office to announce is that it will work more closely with investment banks in selling gilts.
What this offshoot of the Treasury will do is form syndicates of banks to sell around £20bn to £30bn of gilts, out of the record £200bn-odd it will have to flog to finance our financially stretched government.
It's quite a substantial innovation for Britain, though other governments do this.
And it's how big companies borrow on bond markets: they hire banks as so-called lead managers or co-lead managers to find purchasers of debt.
Although the Debt Management Office will continue to use auctions and mini-tenders for the majority of gilt sales, syndicating a chunk is necessary because of the difficulty it has already experienced in selling long-dated gilts, or borrowing for 15 years or longer.
Plainly the Treasury wants to borrow as much as possible at a long maturity, so that it's not bequeathing a massive refinancing problem to the next government or the one after that.
As I implied in my earlier note, pension funds claim they want to buy long-dated bonds or index-linked bonds (which tend to be long dated). But they rarely turn up and buy the stuff in conventional auctions.
So the hope of the Treasury - and anyone who wants to minimise the risk that we might have to seek emergency funding from the IMF - is that silken tongued investment bankers can persuade them to buy the stuff.
And for those who believe investment bankers got us into the global economic crisis, perhaps this is public service as penance to help get us through it.
Except that the banks and bankers are bound to be handsomely remunerated for flogging this debt - much of which is only necessary because of the huge costs of bailing out our big battered banks.
Some might say that an ill wind they generated is rewarding them.
