The decline was broad on the stock exchange following Donald Trump's tariff shock. The threat of 50-percent tariffs on EU goods was delivered on the social network Truth Social, minutes after a threat of 25% punitive tariffs on the American IT giant Apple.
Among the index-heavyweights, telecom equipment manufacturer Ericsson dropped 2.3 percent and industrial giant Atlas Copco fell 1.7 percent. And a total of 24 out of 30 stocks in the OMXS30 index closed in the red.
Wall Street ended Thursday's trading with the S&P 500 index at an unchanged level, but in the opening on Friday, the leading indexes lost around 1 percent after Trump's new tariff threats.
The tariff chaos follows a turbulent Thursday on the market since the interest rate on 30-year US bonds rose to 5.15 percent, the highest level in nearly 20 years. The interest rate shock took off since the Trump administration's budget with disputed tax cuts – which risk significantly increasing the US budget deficit and national debt – was approved by the House of Representatives.
In Friday's trading, the US interest rate eased slightly, to 5.04 percent – which is still an unusually high level historically.
The dollar, which also took a hit in the turbulence on Thursday, recovered somewhat and was priced at 9.54 kronor at the close of trading. One euro cost 10.81 kronor.
With Friday's decline, the Stockholm stock exchange fell a total of 3.2 percent during the past week. Counted from the turn of the year, the stock exchange has fallen 1.7 percent.
