In which city is the price of gold "fixed" daily?

The price of gold is fixed in London, the historic centre of the London bullion market. The process produced the London Gold Fixing, a benchmark used by dealers, financial institutions, miners, refiners, investors and jewelry businesses around the world.

The first London gold fixing took place on 12 September 1919, when five major bullion firms met to establish a reference price. The fixing was originally conducted at the London offices of N. M. Rothschild & Sons, but it later moved to a telephone-based system. Since 2015, the benchmark has been known as the LBMA Gold Price and is administered through an electronic auction.

The wording “fixed daily” reflects the traditional expression, although the benchmark is set twice on most London business days: once in the morning and once in the afternoon. London remains the canonical answer because the question refers to the historic gold-fixing centre, not to every modern market where gold is traded.
