The SPDR Gold Trust, the largest gold ETF globally, increased its holdings by 12.02 tons on December 23, 2025, bringing its total to 1,064.56 tons. This substantial addition reflects a growing interest in gold as a safe-haven asset. Meanwhile, the iShares Silver Trust, the leading silver ETF, experienced a remarkable one-day increase of 533.01 tons, marking the largest single-day inflow since January 2023. The trust now holds 16,599.25 tons of silver. These significant inflows into precious metals ETFs may influence market dynamics, potentially impacting altcoin performance as investors diversify their portfolios.
