Gold demand, excluding over-the-counter (OTC) investments, decreased by 6% year-on-year to 929 t in the second quarter, as a significant decline in jewellery consumption overshadowed moderate gains in other sectors, the World Gold Council (WGC) revealed on July 30. However, including OTC investments, total gold demand increased by 4% year-on-year to 1 258 t, marking the highest second quarter in the data series since 2000, the WGC said.
