Here's a world gold council (i know...) review/survey of central banks gold holdings from mid 2025 (https://www.gold.org/goldhub/research/central-bank-gold-rese...). It notes that gold purchases (by mass) have been elevated going back to ~2023.
Gold prices have also been on an upward trajectory ever since 2023 (https://goldprice.org/gold-price-history.html)
Whatever is happening now is bigger than actions over the last year.
