China’s central bank extended its gold-buying streak for the 18th straight month in April, according to fresh data from the People’s Bank of China.

China’s gold reserves increased to 74.64 million fine troy ounces, up from 74.38 million ounces in March. The total value of these reserves climbed to $344.17 billion by the end of April, compared to $342.76 billion a month earlier.

The rise in reserve value comes after March saw the first decline in months, largely caused by a sharp drop in gold prices.

Gold prices remained under pressure in April for the second consecutive month, as fears over rising oil prices linked to the Iran conflict fueled inflation concerns. Investors worried that persistent inflation could force central banks to keep interest rates higher for longer.

However, gold regained some strength toward the end of April thanks to a weaker U.S. dollar and easing crude oil prices.
