Indeed because under normal circumstances I would assume these bonds are mostly held to maturity. But why do they have to sell them now? I was under the impression it was to cover some margin calls.

And to your point about broken yield curve… to some extend I agree that governments should step in when there are technical liquidity issues (i.e there is temporarily not enough money to go around but all business is sound) but at some point you have to wonder if there is no liquidity simply because no one wishes to buy these assets in the current market.

We may not remember but interest rates have been above 10% before, and with inflation where it is at now, it might simply be that the market expects yield to go up significantly in the near future thus it would make sense for the yield curve to invert. Is it then that BoE is solving liquidity issues or again bailing out failing pension schemes? I don’t know of course it’s just a bit smelly.
