Given that we are only providing the full text of the Code to the market in May, there will be a period of time for market participants to adjust their practices where necessary (which should hopefully not be much) to be in line with the principles in the Code.
This period of time might potentially be as short as six months, but no more than twelve months for the vast majority of market participants. How much effort this might require will in part depend on the nature and extent of your engagement with the FX market. In drafting the Code, we have always kept the principle of proportionality at front of mind.
