What Is the London Fix Gold Price? The Daily Benchmark Explained (2026)

The London Fix, now officially called the LBMA Gold Price, is the daily benchmark that sets the reference price for gold transactions worldwide. Banks, central banks, gold miners, jewelry manufacturers, and gold IRA custodians all use it. If you own gold or are considering a gold IRA, the price you pay traces back to this auction, held twice every business day in London.

The Origins of the London Gold Fix (1919)

Gold had been traded in London for centuries before a formal fixing process existed. The problem was price opacity: every dealer quoted their own number, and there was no agreed reference for large contracts or institutional trades.

On September 12, 1919, five London bullion houses gathered at the offices of N M Rothschild & Sons in St Swithin’s Lane to set a common daily price. Those five firms were:

• N M Rothschild & Sons (chair)
• Mocatta & Goldsmid
• Samuel Montagu & Co.
• Pixley & Abell
• Sharps Wilkins

The initial fix was set at $20.67 per troy ounce, reflecting the gold standard price of the era. London was chosen because it was already the world’s dominant commodity trading center, with established infrastructure for vaulting, assaying, and shipping physical metal.

For the first decades, the process ran once daily. It expanded to twice daily (AM and PM) to cover both Asian and American market sessions. The chair communicated with member banks by telephone. When a price was proposed, each bank signaled whether they had buying or selling interest at that level. The price moved up or down until supply and demand balanced, at which point the fix was declared.

The five founding members remained the core of the London Gold Market Fixing Limited committee through most of the twentieth century, though the cast of institutions changed as banks merged, acquired each other, or exited the commodity business.

How the Original Twice-Daily Auction Worked

The AM fix ran at 10:30 AM London time; the PM fix at 3:00 PM London time. Those two times were chosen to catch the close of Asian trading sessions and the opening of North American markets, making the London price relevant to dealers in both hemispheres.

The chairman proposed an opening price based on the current spot market. Representatives at each member bank then communicated the net buy or sell interest from their clients at that price. If buyers exceeded sellers, the price moved higher. If sellers exceeded buyers, it dropped. This continued until both sides balanced, typically within a few iterations.

Each bank representative had a physical paper flag on their desk. As long as any flag was raised, the chairman could not declare the fix. Once all five flags were lowered, signaling that each bank was satisfied with the balance at the current price, the price was announced and published.

That ritual, with physical flags in a physical room, continued until 2004, when the process moved to telephone conference calls. N M Rothschild & Sons withdrew from the gold market that same year and gave up the chair. The Bank of Nova Scotia (Scotia Mocatta) eventually took over. The core mechanics stayed the same: a chairman, member banks, and a price that moved until supply matched demand.

The published fix was used immediately for contract settlements, central bank reserve valuations, and producer hedging agreements. A gold miner selling output on a “PM fix” contract knew exactly what price they would receive that afternoon, regardless of intraday spot market swings.

The 2015 Transition: From London Gold Fix to LBMA Gold Price

The Libor manipulation scandal of 2012 changed how regulators viewed benchmark-setting processes everywhere. If bank representatives could manipulate an interest rate benchmark through private phone calls, the same concern applied to commodity benchmarks. The London Gold Fix, conducted by a small group of banks on an unmonitored conference call, became an obvious regulatory target.

The most prominent case came in 2014. The UK Financial Conduct Authority (FCA) fined Barclays £26 million after finding that one of its traders had placed orders during the May 28, 2012 PM gold fix designed to keep the price below a level where a client’s barrier option would have triggered a payout. The trader directly profited from this maneuver. The case made front pages across the financial press and ended any defense of the old structure.

The London Bullion Market Association (LBMA) and ICE Benchmark Administration (IBA) worked together on a replacement. On March 20, 2015, the London Gold Fix held its last session under that name. The LBMA Gold Price launched the following business day.

Three concrete changes came with the transition:

1. Electronic, not telephone: The auction runs on an IBA-operated electronic platform. All bids and offers are submitted digitally and logged with timestamps, creating an audit trail that was entirely absent from the old telephone process.
2. More participants: Membership expanded beyond the original five banks. Any firm meeting the LBMA’s credit and compliance criteria can apply to participate directly in the auction.
3. Regulated benchmark: IBA administers the LBMA Gold Price under FCA supervision. The process must meet IOSCO (International Organization of Securities Commissions) Principles for Financial Benchmarks.

The price itself, the method of balancing supply and demand, and the twice-daily schedule stayed the same. Only the infrastructure and oversight changed.

How the LBMA Gold Price Auction Works Today

IBA runs two auctions on each London business day: 10:30 AM and 3:00 PM London time. The afternoon (PM) auction carries more weight for contract settlements because it coincides with the overlap of European and early US trading sessions, when liquidity is highest.

The auction runs in iterative rounds:

1. IBA sets an opening price near the current spot market price.
2. Direct participants submit net buy or sell volumes at that price.
3. IBA calculates the imbalance. Buyers outweigh sellers: price steps up. Sellers outweigh buyers: price steps down.
4. The process repeats at the new price. Participants revise their orders each round.
5. When the imbalance falls within a defined threshold (currently 10,000 troy ounces or less), the auction closes.
6. IBA publishes the fix price in USD, GBP, and EUR simultaneously within seconds.

The entire process typically takes three to five minutes when the market is calm. During periods of high volatility, it can run longer as participants adjust positions repeatedly before settling on a price.

The LBMA publishes the current list of direct participants on its website. That list has grown significantly from the original five London Gold Market Fixing Limited members. Participants include major international banks and qualified commodity trading firms. Any entity wishing to participate directly must meet the credit, technology, and compliance requirements set by the LBMA and IBA.

The resulting price is published on Bloomberg, Reuters, and the LBMA website immediately after the auction closes. It becomes the reference point for every contract, ETF, and reserve valuation that specifies “LBMA Gold Price” as the pricing basis.

Spot Price vs. London Fix: What Is the Difference?

The two prices are closely related. The spot price at the time of the auction serves as the starting reference for the fix. Because the auction aggregates large institutional buy and sell interest, the final fix can land slightly above or below the prevailing spot price when the auction closes. In practice, the gap is almost always small, often under $1 per troy ounce. During unusual market conditions, such as a major geopolitical event breaking mid-auction, the spread can widen temporarily.

For retail buyers, spot price is the familiar number. A coin dealer or online bullion platform quotes prices as spot plus a premium. A one-ounce American Gold Eagle might cost spot plus $60 to $100, with that premium covering manufacturing, distribution, and dealer margin. The LBMA Gold Price is not directly visible to retail buyers, but it shapes the spot market that retail pricing then builds on.

Why Bullion Dealers Reference Both Spot and Fix

Most retail gold transactions use spot pricing. Three types of institutional transactions specifically require the LBMA Gold Price:

Long-Term Supply Contracts

Gold mining companies often sell output forward at a price indexed to the PM fix on the delivery date. A contract that says “deliver 5,000 troy ounces at the PM fix price on June 30” gives both parties a transparent, independently administered reference. Neither side can dispute the price because it is a publicly published, regulated benchmark administered by IBA under FCA oversight. This transparency is exactly what forward contracts require.

ETF Net Asset Value Calculations

Gold-backed ETFs, including SPDR Gold Shares (GLD), calculate their daily net asset value (NAV) using the PM LBMA Gold Price. This is why an ETF’s official NAV can differ slightly from its intraday trading price: the intraday price tracks spot continuously, while NAV resets once each day at the PM fix. Understanding this explains the small “tracking difference” that appears in ETF data.

Central Bank and Reserve Reporting

Central banks report gold reserve values using the LBMA Gold Price. The International Monetary Fund (IMF) also uses it as the reference for gold in countries’ international reserve data. A consistent, auditable twice-daily benchmark is far easier to standardize across 190+ member countries than a continuous spot price that changes every second.

Bullion dealers know both numbers because clients ask “what is gold at?” (spot) and because large transactions reference fix-based contracts. A dealer handling institutional orders needs both reference points to price accurately and meet contract specifications.

What the London Fix Means for Gold IRA Investors

If you hold or are considering a gold IRA, the London Fix connects to your account in two ways.

First, the custodian or dealer handling your gold IRA purchase sets their prices from spot market data. That spot data tracks the LBMA Gold Price closely. When you see a quote for IRS-approved gold coins or bars inside a self-directed IRA, you are looking at spot plus a dealer premium, with spot anchored to the LBMA benchmark twice daily.

Second, the AM fix (10:30 AM London, which is 5:30 AM or 6:30 AM US Eastern depending on daylight saving) and the PM fix (3:00 PM London, which is 10:00 AM or 11:00 AM US Eastern) mark the moments when institutional price discovery concentrates. Spot prices sometimes move noticeably right after a fix is published, as market participants react to the benchmark.

This does not mean you should try to time purchases around the fix. Retail premiums over spot change more slowly than spot itself, and the window around a fix auction is too brief for most retail investors to act on. What it does mean: any gold IRA company that cannot clearly explain how it prices its metals (relative to spot, with premiums disclosed) should prompt questions before you commit.

The IRS requires that metals held in a self-directed IRA meet specific fineness standards per IRS Publication 590-A. Those rules govern eligibility, not pricing. The custodian and dealer you choose determine the premium you pay above spot. Comparing those premiums and annual fees across multiple providers before committing can significantly affect your total cost over the life of a 10- or 20-year retirement account.
