One hand buys bonds, the other stops
The government is managing the long end by shifting its borrowing to the front end at exactly the moment the Fed has stopped supplying reserves there.
On 19 August the Treasury said it would increase its buybacks of 10- to 30-year government bonds "by at least double" — from $2bn to at least $4bn per operation, running 9 September to 4 November, which analysts put at roughly $32bn a quarter (Bloomberg). The 30-year fell 10 basis points to 5.18% on the news, back from its highest level since 2007. Six days earlier, the New York Fed announced the opposite move at the other end of the curve. Reserve management purchases — the Desk's routine buying of Treasury bills to keep bank reserves "ample" — were cut to zero for 14 August to 14 September, having already been tapered to about $10bn a month. These are different instruments and it is worth being precise about why. A Treasury buyback creates no money. Treasury retires long bonds and funds the purchase by issuing short bills: the total debt is unchanged, the average maturity shortens, and someone else has to hold more bills. A Fed reserve-management purchase does create reserves. So the government is currently taking duration risk out of private hands and simultaneously not adding the bank reserves that would normally help finance the resulting bill supply. What has to stay true for this to work: money funds and banks keep absorbing bills at the front end without the repo market tightening. Watch SOFR, which sits at 3.65%. It has not moved. If it starts printing above the Fed's administered rates in the second week of September, when buybacks begin and reserve purchases are still off, that is the tell.
