What is London 4pm Fix?

06/09/2022 at 11:25AM

London is one of the biggest financial hubs, and when it comes to foreign exchange, it beats any city in the world in traded volume. That is why large volumes of contracts are executed at 4 pm London time. The price thus obtained is known as the London Forex Fix and is set daily, Monday to Friday.


The currency "fixings" became infamous after five major banks were fined $3.4 billion dollars in 2014 for misconduct. That was due to the trading behaviour of banks around the "fix". Essentially traders in these banks were front-loading trades ahead of clients, a behaviour that is illegal in heavily regulated commodities and the stock markets. Despite these "fixes" remain popular, especially the London Fix.  


Why is the London 4 pm fix so popular?

The reason for the popularity of the London Fix is twofold. First, due to the 24x7 nature of the forex market, individuals who require a valuation of a currency for any given day will seek a "fix". Second, due to the sheer volume executed (40% of the $5.4 trillion daily global volume) at 4 PM London Time, it seems the most obvious choice. 


Now that we establish the importance of the London Fix, let us see how to access the price at 4 PM London time. There are various ways to do so but let's see some convenient ways.
