Grey listing means that FATF has increased a country under closer monitoring to see how well it is doing against money laundering and funding for terrorism. People also call the “grey list” the “increased monitoring list”. When the FATF puts a country under increased monitoring, it means that the country has agreed to fix any strategic problems quickly and within the timeframes set by the FATF. The country is then subject to more monitoring. This FATF grey list is made up of the countries that are thought to be safe havens for funding terrorism and laundering money.
This is a warning to the country that if they don’t resolve their problems, they could end up on the blacklist.
