Gold futures nudged higher for a second day Tuesday morning, as traders expressed anxiety over the outlook for the global economy in 2016.

With investors looking for a safe haven amid geopolitical tensions and falling stocks, US gold for February was up 4 dollars at $1079 an ounce, having touched $1082 a few hours ago.

There will be no major economic data released today, giving markets a chance to catch their breath after yesterday’s drubbing of global equities.

Traders will instead be watching developments in the Middle East, where tensions between Iran and Saudi Arabia risk escalating to a wider conflict.
