LONDON/SYDNEY—World shares skidded on Monday as warnings that Russia could invade Ukraine at any time drove oil prices to seven-year peaks, belted the euro and sent investors scuttling back to the safe-haven government bonds they have been dumping all year.
Europe’s STOXX 600 share index tumbled 2.5 percent, Wall Street futures were down 0.6 percent, though it was Ukraine’s government bonds that understandably showed the most alarm as they slumped 10 percent.
