Kevin Walter’s work-from-home experiment lasted mere hours. On March 12, the Barclays trader was so alarmed by the turbulence flaring up in the US government bond market that he jumped in a car and made a dash from his home in Connecticut to his office in the normally crowded Times Square.
Trading conditions for US Treasuries had been poor for a while. But that Thursday — the day after Covid-19 was declared a pandemic — unnerving glitches escalated into mayhem. “It was a shock to see these distortions in the market,” says Mr Walter, co-head of global Treasury trading at the British bank.

“There was a point in time when we were wondering if the bond market would really ever function again,” says Nick Maroutsos, co-head of global bonds at Janus Henderson, an investment group. “If it continued for a couple of weeks, we were thinking we were looking at doomsday.”
To avert calamity, the Fed delivered an unprecedented series of measures, surpassing even its response to contain the crisis over a decade ago. Trading conditions soon began to stabilise, volatility ebbed and before long, the central bank had stoked a historic rebound in financial markets.
Nonetheless, the events of March have cast a long shadow. Such turmoil simply shouldn’t…
