I haven’t had time to digest the implications of this story which has been around for at least a month, but only now seems to be attracting attention (I’ve seen it in a few different places today). Apparently, short sellers in the US Treasury bond market are failing to deliver the securities they’ve sold. As long ago as 1 October, the shortfall was more than $2 trillion by one report. Via Felix Salmon, here’s Helen Avery in Euromoney.
I’m not an expert on this stuff, but it seems to raise the question of whether bond markets can and should continue to exist in their current form. Maybe the US and other Treasuries should be selling bonds directly, and offering repurchase options to provide liquidity, perhaps using the banks they’ve already part-nationalised to handle the mechanics.
