Gold rallied for the second straight session on Thursday, climbing to its highest level in over a week after the US central bank signalled only gradual rate tightening and the dollar slid to its lowest in five weeks. Spot gold gained 0.7 percent at $1,227.43 an ounce by 3:03 p.m. EDT (1903 GMT), after touching $1,233.13, the highest since March 6. US gold futures for April delivery settled up 2.2 percent at $1,227.10.
The Federal Reserve on Wednesday raised US interest rates for the second time in three months, as expected, but did not flag any plan to accelerate the pace of monetary tightening as some investors had anticipated.
"I think people were betting on a dot plot and a Fed statement that was more hawkish than what we got," said Trey Reik, senior portfolio manager for Sprott Asset Management USA.
Gold is highly sensitive to rising US interest rates, as these increase the opportunity cost of holding non-yielding bullion, while boosting the dollar, in which it is priced.
In other precious metals, spot silver rose 0.05 percent to $17.31 per ounce, after hitting its highest in a week at $17.56.
Platinum climbed 0.8 percent at $957 per ounce, having touched $971.60, its highest since March 7. Palladium gained 0.2 percent at $764.70 per ounce after hitting a week high of $774.70.
