I&E window is known as the investors and exporters Window, otherwise called the investors and exporters Forex window (I&E FX Window). It's the market trading sector for investors, exporters, and end users that permits forex deals to be made at market (supply and demand) determined exchange rate. In a move to integrate all components of the Nigerian currency markets, the CBN had announced the collapse of all forex windows into the Investors & Exporters (I&E) window and a result, all transactions will now take place through the Investors and Exporters (I&E) window, where market forces will govern the exchange rate.
