‘Dude, Get Back to Your Desk’: The Week That Roiled Bond Markets

Thomas Costerg doesn’t usually go to bed with a computer, but he couldn’t help himself Thursday night after what had just happened in the Treasury market.

“I could not sleep well,” said the senior U.S. economist at Pictet Wealth Management in Geneva. “These were quite extreme moves.”

With a ferocity that caught nearly everyone off guard, one of the most vital numbers in global finance -- the yield on 10-year Treasuries -- spiked back to where it’d been before the pandemic caused markets to go nuts 12 months ago.

You might think that was reason to celebrate -- a welcomed finish line to cross as the world tries to return to normal. After all, yields had sunk toward zero because of virus panic. So surely getting back to 1.47% -- where 10-year notes finished on Feb. 21, 2020, before a weekend of dire coronavirus news woke investors up to the threat and kick-started the most painful period in markets since the Great Recession -- would be welcomed news?

Not at all.

“The mood was bordering on frantic,” said Emily Roland, the Boston-based co-chief investment strategist for John Hancock Investment Management and its $164 billion of assets.

Almost everything that matters was red Thursday. Treasuries sank, driving the yield on 10-year notes up as many as 23 basis points to 1.61%. Stock losses were most pronounced in Nasdaq-100 and small-cap shares that, with help from frenzied speculators and economic optimists alike, had led equities higher. Corporate bonds continued to rack up the biggest losses since the pandemic began as companies scramble to sell debt before yields go up even more. The dollar surged in a classic haven trade.

The bond market has for weeks signaled an inflection point could be coming, with soaring interest-rate options and the steepest U.S. yield curve in years suggesting big shifts afoot. That also suggests turmoil may resurface in the days ahead.
