Citigroup plans to build a Heathrow Airport vault to enter the trillion-dollar London gold market

As demand from investors for precious metals continues to grow, Citigroup is gradually moving closer to the core of the global gold market, seeking to play a larger role in London’s gold infrastructure. According to informed sources, the bank plans to collaborate with Malca-Amit to use a high-security vault near Heathrow Airport, while also advancing the process of becoming a clearing member of the London gold market. Gaining this qualification would place Citigroup among the few institutions at the heart of daily gold settlement processes, in which ownership of physical gold is transferred to complete transactions.

London remains the dominant hub for global gold trading, with commercial vaults and the Bank of England holding over $1 trillion worth of gold bars, and clearing members handling hundreds of billions of dollars in transactions daily. The current group of clearing members—including JPMorgan, HSBC, ICBC Standard Bank, and UBS—has shrunk over time, which may draw more attention to Citigroup’s initiative to enter this market as it seeks to integrate more deeply into this concentrated and systemically important market structure. The vault capacity provided by these institutions allows metals to change hands efficiently, forming the backbone of global gold liquidity.

The economic value behind this infrastructure may also be increasing. Vault facilities are typically located near major transport hubs like Heathrow Airport for efficient transport of metals. Malca-Amit’s vault has previously been described as capable of storing hundreds of tons of gold and a significant quantity of silver. Storage service revenue is generally tied to the value of the metals stored, and with gold prices rising about 45% over the past year, combined with renewed investor interest, this revenue pool may be expanding, which could reinforce Citigroup’s strategy of further delving into the physical realm of the gold market.
