Allocated Bullion Exchange (ABX) Review

Allocated Bullion Exchange (ABX) is an institutional trading platform for physical gold, silver, and platinum that launched under its current name in 2016 after several years of testing as Bullion Capital.

It was built by CEO Thomas Coughlin, who started the project in 2010 after finding the wholesale bullion market stuck in slow, paper-based, over-the-counter trading.

ABX runs on a platform called MetalDesk, which connects buyers and sellers across multiple countries and lets them trade fully allocated metal instead of pooled or unallocated positions. This review looks at what ABX actually offers, how its platform works, and who it makes sense for.

Key Points

• ABX is an institutional exchange for allocated physical precious metals, not a retail bullion dealer, so individual investors need to go through a Full or Associate Member to get access.
• The MetalDesk platform runs 23 hours a day, five days a week, with a central limit order book and live pricing pulled from seven global trading and storage hubs.
• Gold traded near $4,050 to $4,100 per ounce in late July and early August 2026, up more than 20% year over year, which is the kind of price environment where allocated storage and counterparty protection matter more to investors.

What ABX Actually Is

ABX is not a bullion shop. It doesn’t sell coins or bars directly to the public, and it doesn’t have a retail storefront. It’s an exchange, similar in concept to a stock exchange, except the product is physical gold, silver, and platinum sitting in vaults rather than shares in a company.

Trades executed on MetalDesk settle against real metal held in allocated form, meaning the buyer holds legal title to specific bars or units rather than a claim on a shared pool.

That distinction matters more than it sounds. In an unallocated account, the metal is a liability on the dealer’s books, and if that dealer goes under, the investor becomes an unsecured creditor.

Allocated metal removes that risk because the client owns the metal outright, stored with a third-party vault, independent of the exchange’s own balance sheet.

ABX built its entire pitch around this structure, positioning itself as the electronic layer that professional and institutional players were missing.

How MetalDesk Works

MetalDesk is the trading engine behind ABX, and it’s worth understanding on its own terms. It uses a central limit order book (CLOB), the same matching mechanism used by major securities exchanges, where buy and sell orders are queued anonymously and matched by price and time priority.

Every user sees the same market depth panel, showing bid and offer levels across the book, so there’s no tiered information advantage for larger players.

A few practical details about the platform:

• It’s web-based, so there’s no software download, and account setup takes under a minute according to ABX.
• It runs 23 hours a day, five days a week, tracking the natural trading cycle across time zones rather than a single exchange’s local hours.
• Users can open either a demo account or a live account before committing capital.
• Pricing is pulled from multiple regional liquidity centres, which ABX says gives tighter spreads than a single-location OTC desk.
• The platform includes account activity reporting, customizable watch lists, and holdings management, so it functions more like a brokerage terminal than a simple order form.

ABX also offers something called an Electronic Vault Warrant, which lets holders use their bullion as collateral for other trades without physically moving the metal. This feature was still listed as “coming soon” on ABX’s own site as of mid-2026, so it’s worth confirming current availability directly with the exchange before assuming it’s live.

Quick Facts Table

Who Can Actually Trade on ABX

This is where a lot of first-time visitors get confused. ABX itself is a membership-based exchange with three tiers: Full Members, Associate Members, and Proprietary Trading Members. These are typically banks, bullion dealers, brokers, refiners, and other institutional players who meet ABX’s onboarding and compliance requirements.

Individual retail investors cannot open an account directly with ABX. Instead, retail access runs through Full or Associate Members who offer client-facing services on top of the exchange.

In practice, this means a retail investor’s actual experience depends heavily on which member firm they go through, since fees, minimums, and customer support are set at that layer, not by ABX directly.

Anyone reviewing ABX for personal investment purposes should treat this as the single most important structural fact about the platform. It’s a wholesale market with a retail door bolted on, not a retail platform with institutional features added.

Market Context: Why Allocated Storage Matters Right Now

Gold has had an unusual run. It spent 2025 climbing past $5,000 an ounce and hit an all-time high just under $5,600 on January 28, 2026, before pulling back through the spring and summer.

As of early August 2026, spot gold was trading in the $4,040 to $4,100 range, still up more than 20% from a year earlier despite the retreat from January’s peak. Silver has moved even more sharply, jumping from around $40 an ounce in September 2025 to a peak near $116 in late January 2026, before settling closer to $57 to $59 an ounce by late July.

That kind of volatility is exactly the environment where allocation status starts to matter to investors, not just price. When gold moves 20% or more in a matter of months, the difference between owning specific, titled bars in a vault and holding a claim against a dealer’s inventory becomes a real financial distinction, not a theoretical one.

Central bank demand has been a major driver of the broader gold rally too. The World Gold Council and multiple bank research desks have pointed to sustained central bank buying as one of the structural supports behind gold’s multi-year climb, alongside inflation concerns and, more recently, renewed conflict in the Middle East pushing up oil prices and inflation expectations.

None of this is unique to ABX. But it explains why an exchange built specifically around allocated, title-backed metal trading has found an audience among institutions that got burned, or got nervous, during periods of counterparty stress in other parts of the bullion market.

Strengths and Limitations

ABX’s core strength is structural. Allocated ownership with full legal title genuinely reduces counterparty risk compared to unallocated or pooled accounts, and the CLOB matching engine gives more price transparency than a lot of traditional OTC bullion desks, where pricing can vary by relationship and negotiating leverage.

Connecting multiple regional hubs into one platform also lets users arbitrage locational price differences that used to require separate relationships in each market.

The limitations are mostly about who can use it and how. It’s not a place to walk in and buy a single gold coin. Access depends on which member firm handles onboarding, so terms aren’t standardized across all users the way they would be on a true retail platform.

And a headline feature like the Electronic Vault Warrant system, which would let investors use bullion as trading collateral, wasn’t fully live as of this review, which limits some of the platform’s advertised flexibility for now.

Conclusion

ABX fills a real gap in the wholesale bullion market by giving institutions and their retail clients an electronic, allocated alternative to opaque OTC trading.

Whether it’s the right fit for an individual investor depends almost entirely on which Member firm they access it through, so that relationship deserves as much scrutiny as the exchange itself.
