LONDON (Reuters) - Nervous investors turned to the safety of gold, government bonds and the yen on Tuesday as concerns mounted about possible U.S. military strikes in the Middle East and the Korean Peninsula.
Signals from Washington that it was prepared to take further action against the Syrian government if it thought it was using chemical weapons was the main driver, with uncertainty about forthcoming elections in France also simmering.
Gold hit its highest since November, emerging market stocks were on their worst run of the year so far, while the euro fell to a four-month low versus a broadly stronger Japanese yen.
"It's a relatively modest reaction but there is a lot of geopolitical risk in global markets at the moment," said TD Securities European head of currency strategy Ned Rumpeltin.
"There is Syria the is more uncertainty about the U.S. economy after relatively weak jobs numbers and we have French elections coming up."
