Gold rose on Thursday en route to its best month in four years as expectations of more monetary easing from central banks and persistent worries over a global recession lifted safe-haven demand.
Spot gold was up 0.2% at $1,715.25 per ounce by 0949 GMT. U.S. gold futures rose 1% to $1,730.60 per ounce.
"Massive monetary support we are witnessing at the movement is helping gold. Despite higher risk appetite, the gold prices until now stayed above $1,700 per ounce, although it did come under pressure because of higher equity markets," Commerzbank analyst Eugen Weinberg said.
"The U.S. Federal Reserve left interest rates unchanged and it should stay there for sometime. Going forward, the unprecedented monetary stimulus provided by the ECB and the Fed is likely to increase demand for gold."
On Wednesday, the Fed kept interest rates near zero and promised to expand emergency programmes as needed to help the battered economy.
The U.S. economy contracted in the first quarter at its sharpest pace since the Great Recession, while economists expect an even sharper contraction in the second quarter.
Focus now shifts to the ECB policy decision, due to be released at 1145 GMT. The central bank is under pressure to deploy even more firepower to prop up an economy that could shrink by a tenth this year.
Bullion has risen more than 9% so far this month, boosted by a wave of stimulus measures from central banks to limit economic damage from the coronavirus-outbreak.
Lower interest rates reduce the opportunity cost of holding non-yielding gold, which also tends to benefit from widespread stimulus measures as it is often seen as a hedge against inflation and currency debasement.
"Investors remain confident about a relatively quick solution to coronavirus, although it is now abundantly clear that central banks will be forced to print a large amount of money," ActivTrades chief analyst Carlo Alberto De Casa said in a note.
"From a technical point of view, a clear climb above the resistance placed at $1,730-$1,735, which has already been tested twice earlier this month, will create space for further rallies in gold."
However, positive trial results for a drug to treat the coronavirus boosted appetite for riskier assets, limiting gold`s advance.
Elsewhere, palladium climbed 2.7% to $1,987.87 an ounce, platinum gained 0.5% to $778.16. Silver edged 0.1% higher to $15.38 per ounce.
