London session

London is the centre of gravity of the foreign exchange market: by settlement volume it handles more than any other centre, and the hours it is open carry the majority of the day’s movement in EUR, GBP and CHF pairs.

When the London session runs

The London session is defined by the hours London keeps: 08:00 to 17:00 local. In UTC that is 08:00 to 17:00 in January and 07:00 to 16:00 in July.

What only this session has

In April 2022, 38% of the world's foreign exchange turnover was reported by dealers in the United Kingdom, more than any other country and twice the United States' 19%. That is the measured basis for calling London the centre of the market, and it is down from 43% three years earlier.

Two scheduled moments belong to this session alone. The Bank of England publishes its rate decision at midday on a Thursday, which is 07:00 in New York for most of the year. And at 16:00 London time the WM/Reuters closing rates are fixed: the benchmark used to value and rebalance multi-currency portfolios and to build published indices. The window it is calculated over used to be a single minute; the Financial Stability Board recommended widening it, and the change came in February 2015. The 16:00 fix is 11:00 in New York, inside the overlap.

What the London session is like

  • The open is the sharpest scheduled liquidity event of the European day. Ranges expand quickly in the first hour.
  • European data — inflation prints, central bank speakers, PMIs — lands during these hours.
  • The last four hours run alongside New York, and that overlap is the busiest window of the entire 24-hour cycle.
