Gold, which is a non-interest-paying asset, could see demand take a hit from higher rates. Once the rate decision has been taken, gold is likely to move higher, Hansen said.

Holdings of SPDR Gold Trust , the world's largest gold-backed exchange-traded fund, fell 0.03 percent to 836.13 tonnes on Tuesday, the lowest since mid-March.
