The core quantitative claims are confirmed by multiple independent outlets citing World Gold Council data. Kitco News and Yahoo Finance both report net central bank purchases of 41 tonnes in May, following 17 tonnes in April, with Poland leading at 18 tonnes for a consecutive month. The 'most since November 2025' qualifier is the only weakly supported element: Kitco describes May as the 'second-highest monthly total of 2026,' which is compatible with being the largest since November 2025 but is not explicitly stated in the WGC-sourced reporting. All numeric facts hold, so the claim is likely true.
