Stocks fell from record highs, oil slumped and Treasury yields touched some of the highest levels in more than a year amid concern the Federal Reserve risks letting inflation accelerate.

The rout in risk assets picked up in the afternoon, starting with a selloff in crude. Oil plunged 8 per cent on concern new restrictions in Europe will hamper demand. Two weeks ago it soared past US$65 a barrel to the highest in almost two years.

The spike in Treasury yields dented demand for tech shares with high valuations, sending the Nasdaq 100 Index tumbling 3.1 per cent. Swings in asset prices also picked up as they often do around major expirations of options and futures contracts, such as tomorrow’s ‘quadruple witching’ event.

“We’re seeing a pattern where an uncomfortable spike in the 10-year Treasury reminds equity investors that their tech stocks are trading well above average,” said Mike Bailey, director of research at FBB Capital Partners.

Ten-year Treasury yields climbed to 1.75 per cent for the first time since January 2020, while the 30-year breached 2.5 per cent for the first time since August 2019 in the wake of Wednesday’s Federal Reserve meeting. Fed Chairman Jerome Powell’s apparent willingness to keep pumping support into the economy and let it run hotter has spurred bets on faster growth and inflation, sending market expectations of price pressures to multi-year highs.

Oil plunged as vaccination efforts in some parts of the world stalled, casting uncertainty over the speed of an economic recovery and a full rebound in global oil demand. West Texas Intermediate crude futures declined for a fifth session, the longest stretch of daily losses in more than a year.

In Asia and Europe, stocks were boosted by lingering enthusiasm from the Fed’s outlook for stronger growth. Automakers and banks, which tend to outperform during cyclical upswings, were higher in Europe. Japan’s Topix jumped past the 2,000 mark for the first time since 1991, becoming the region’s top-performing major equity index this year.

Japan’s government bond yields rose on a Nikkei report that the Bank of Japan is considering widening the trading range around the 10-year target, which could spur concerns about policy tightening.
