The Treasury becomes a buyer of its own debt
The fiscal authority is now actively managing the price of its own long debt, which is what you do when you are not confident the market will clear it.
On Wednesday the US Treasury said it was "increasing, by at least double, the size of liquidity support buyback operations" for bonds maturing in 10 to 20 and 20 to 30 years. Repurchases of $2bn become "at least" $4bn. The 30-year yield fell about 9 basis points to 5.2%, the 10-year 7bp to 4.64%, and the dollar had its worst day in three months (FT, Bloomberg). What a buyback is: the Treasury takes cash and buys back bonds it has already issued. It is not QE — no money is created, the Fed is not involved, and the debt does not go away. It gets refinanced. And because the Treasury has a deficit to fund, the cash to buy the long bonds has to come from issuing something else. Market participants expect that something to be bills. "Given the amount of issuance required to fund the deficit, this implies greater issuance at the short end of the curve," said Daniel Murray of EFG International. So the mechanism is: shorten the average maturity of the national debt to relieve pressure at the long end. That works, and it has an obvious cost. Every dollar moved from a 30-year bond to a three-month bill is a dollar the government has to reprice every three months. The US spent 2020-21 not doing this, and is now paying for it. Doing the reverse buys relief today by buying more rollover risk tomorrow. The context is a fortnight of ugly auctions: $42bn of 10-years cleared at 4.683%, the highest since 2007; $25bn of 30-years at 5.216%, the highest since 2001. A $16bn 20-year sale is next.
