Spot gold surged today in the short term, breaking through the key level of $4740 per ounce and hitting a new all-time high, with an intraday increase of 1.48%. Behind this rally is closely related to the recent gold purchase plans of the Polish central bank. It is reported that the Polish central bank has approved a large-scale gold reserve expansion plan to buy 150 tons of gold. This move reflects the ongoing optimism of global central banks towards gold assets, further boosting market demand for precious metals. Analysts point out that similar official purchase actions often strengthen the upward momentum of gold and support continued price strength.
