A rate rise and a return to bond buying, in the same season
Banks are running short of the cash they keep at the Fed, which is pushing the Fed back into buying bonds at the moment it is most likely to raise rates, and whether anyone believes the word 'technical' is what markets will test.
Traders in futures markets now put the odds of the Federal Reserve, America's central bank, raising interest rates next week above 85%, according to the FT, up from the 70% we quoted last run. Friday's data showed inflation stuck at 3.4%, with oil above $100 a barrel and federal debt past $40tn, and Governor Christopher Waller had already said a rise 'may be appropriate' if August's improvement proved fleeting. In the same week, the president of the Fed's New York branch, John Williams, said the Fed is 'getting closer' to buying bonds again. Raising rates is how a central bank tightens and buying bonds is normally how it loosens, so the two arriving in the same season is the thing worth understanding. Williams describes the purchases as technical, with 'no implications for monetary policy', and says the Fed will stop letting its bond holdings shrink in December (sweep). The plumbing explains why both can be true at once. Banks keep cash on deposit at the Fed, called reserves, and that pile fell to $2.895tn in the week to September 2, the lowest in 39 weeks. It fell because the Treasury Department, which borrows the money the government spends, has built its own account at the Fed up to $967.9bn, a four-month high, and every dollar the Treasury holds there is a dollar not in the banking system. There used to be a cushion. The Fed's overnight facility for spare cash, where lenders park money with the Fed against bonds put up as security, absorbed drains like this from 2022 to 2024. It is now down to $626mn, empty in all but name. With no cushion left, keeping overnight interest rates inside the Fed's target range means the Fed has to add to what it owns, whatever it decides about the policy rate. So the plausible autumn picture is a Fed that raises rates, a Fed that buys short-term government IOUs, and a Treasury that buys back government IOUs that do not come due for twenty or thirty years at up to $14.5bn a week. None of that contradicts itself. The difficulty is what it looks like. Chair Kevin Warsh told the Jackson Hole conference two weeks ago that the Fed's balance sheet, the list of what it owns and owes, should be reserved for genuine crises and otherwise used sparingly, if at all. A restart labeled 'technical' three months later will be read by some as exactly what he said he would not do. The market has priced half of this. Three-month government IOUs pay 3.91%, already above the 3.62% that banks pay to borrow cash overnight against bonds put up as
