The intervention managed to calm the panic, notes The Economist. The incident suggests that US banks and businesses are “short of cash… A spiking repo rate was an early warning sign before the financial crisis.”
“Don’t worry,” says Bill Dudley on Bloomberg. The jump was due to a confluence of benign events. A US corporate tax deadline on 15 September meant there was more demand for cash than usual as businesses emptied their bank accounts. A large auction of US Treasury bills at the same time generated a further surge in cash demand. A more systemic factor is that until last month the Fed had been selling down the $4.5trn bond portfolio it built up through quantitative easing after the 2008 financial crisis. The sales have been “soaking up bank cash reserves” so there are fewer greenbacks to go around.
“Banks don’t seem stressed for funding,” agrees Jon Sindreu in The Wall Street Journal. As the Fed has unwound part of its asset portfolio and there is less cash swimming around the central bank may now need to return to using “pre-crisis” techniques – injecting money whenever there is a squeeze – to manage repo rates. In the topsy-turvy world of modern central banking, that is perhaps one small sign of normalisation.
