SPDR Gold Trust GLD, the world's largest gold-backed exchange-traded fund, said its holdings rose about 0.5% to 1,013.10 tonnes on Tuesday.

Although gold is considered a hedge against inflation and geopolitical risks, interest rate hikes would raise the opportunity cost of holding non-yielding bullion.
