Gold surged to the highest level in more than six years as fast-rising tensions in the Middle East stoked demand for haven assets, with Goldman Sachs Group saying that bullion offered a more effective hedge than oil to the crisis. Palladium extended gains to an all-time high. Bullion neared $1 600/oz as Tehran said it would no longer abide by any limits on its enrichment of uranium following the killing of General Qassem Soleimani. In addition, President Donald Trump said he was prepared to strike Iran “in a disproportionate manner” if it retaliates against any US target.
