The Treasury buys the long bonds. The Fed edges toward the short ones.
Banks running short of spare cash, while the Treasury is already stepping in to buy long-dated bonds, leaves the central bank less room to raise rates without breaking something in the short-term cash markets that keep trading desks running.
John Williams, who runs the New York branch of the Federal Reserve, America's central bank, which sets interest rates, said this week the Fed is “getting closer” to restarting bond purchases in order to keep the banking system supplied with cash, that the shrinking of its holdings will halt in December, and that banks should use the Standing Repo Facility freely, according to market commentary summarized here. That facility is the Fed's backstop window for lending banks cash overnight against bonds put up as security. The same source puts use of the opposite facility, where banks and money funds park spare cash with the Fed overnight, at $626mn on September 8, down from $702mn on September 3. The Fed's total holdings stood at $6.7tn on September 2. A central banker inviting banks to lean on a backstop is not a weekly occurrence, and it matters because two arms of the government are now moving toward buying government debt at once. We have not seen the speech text and this is a single second-tier source, so hold the specifics loosely. The mechanism is not in doubt. The parking facility is the overflow tank: when banks and money funds have more cash than they want, it sits there. When it is nearly empty, every dollar the Fed lets roll off its holdings comes directly out of the cash banks keep at the Fed, and the lending window becomes the pressure valve. A central banker telling banks to use it “freely” is saying the tank is empty before the pipes groan. Put that beside the Treasury Department, which borrows the money the government spends. It began an expanded program of buying back its own bonds this week, with weekly limits reported at $14.5bn, and its first large operation bought $5.19bn of a $6bn maximum while interest rates rose (FT). The Treasury buys the government IOUs that do not come due for twenty or thirty years and pays for them by selling short-term ones. The Fed, if Williams is right, will soon buy those short-term IOUs to top up bank cash. Two arms of the state buying their own paper at both ends, both insisting it is technical. Perhaps it is. Buying bonds to manage the cash in the system is not the crisis-era program known as QE, and Williams was careful to say so. But the Fed is being pushed toward buying at the moment traders put roughly 70% odds on it raising rates on September 16. A central bank raising the price of money while adding to the quantity of it is not an emergency. It is the position a central bank finds itself in when the g
