My guess is money coming out of bonds for covid recovery equities and commodities driving rates higher. I guess the thought is the rotation is tech investors derisking and going bonds and covid recovery stocks as well. This may have nothing to do with inflation which the fed already said doesn't exist.
Yeah, this is based on the specter of inflation which the MM and the stock pundits have been foaming about since the election. Self fulfilling prophecy. Interest rates were and are so low it is easy to sell bonds and join the swing trade. I saw the ten year yield jump five basis points in half an hour this morning. I would guess 1.5 % is a line that cannot be crossed without major stock market damage.
The whole thing is comical of course because a market crash will crush yields which everyone knows.
