Global markets were shaken by the crisis in Ukraine

Global markets were shaken again on Monday, amid uncertainty over how much oil prices will rise and how sanctions against Russia over its invasion of Ukraine will affect the global economy.

Stocks fell first, then jumped. Investors resorted to buying gold and the Russian ruble fell to an unprecedented level.

The S&P 500 fell 0.3% but initially fell as much as 1.3%, after several Western countries moved to isolate some banks from a major international payments system. The US Treasury also announced new sanctions to freeze any assets of the Russian Central Bank in the United States or in the hands of Americans.

The United States announced that Germany, France, Britain, Italy, Japan, the European Union and other countries would take similar measures against the Russian Central Bank, which announced the closure of the Moscow Stock Exchange on Monday.

Oil prices on both sides of the Atlantic are up about 4% amid uncertainty about what will happen to oil production because Russia is one of the major producers.

In pursuit of steadier profits, many investors bought US government bonds, cutting the yield on the 10-year note by 0.10 percentage point to 1.87%.

The price of gold rose 1.2%.

In Europe, the German index fell 0.9%, the French CAC 40 lost 1.5% and the British FTSE 100 lost 0.6%.

In the United States, the Dow Jones Industrial Average lost 183 units (0.5%) to settle at 33,875 and the Nasdaq Technology Index rose 0.5%, despite falling 1% in the morning.
