Terrorism financing is the provision of funds or providing financial support to individual terrorists or non-state actors. Most countries have implemented measures to counter terrorism financing (CTF) often as part of their money laundering laws. Some countries and multinational organisations have created a list of organisations that they regard as terrorist organisations, though there is no consistency as to which organisations are designated as being terrorist by each country. The Financial Action Task Force on Money Laundering (FATF) has made recommendations to members relating to CTF. It has created a Blacklist and Greylist of countries that have not taken adequate CTF action. As of 24 October 2019, the FATF blacklist (Call for action nations) only listed two countries for terrorism financing: North Korea and Iran; while the FATF greylist (Other monitored jurisdictions) had 12 countries: Pakistan (see Pakistan and state-sponsored terrorism), Bahamas, Botswana, Cambodia, Ghana, Iceland, Mongolia, Panama, Syria, Trinidad and Tobago, Yemen, and Zimbabwe. In general, the supply of funds to designated terrorist organisations is outlawed, though the enforcement varies. Initially the focus of CTF efforts was on non-profit organizations, unregistered money services businesses (MSBs) (including so called underground banking or ‘Hawalas’) and the criminalisation of the act itself.

Many initiatives have stemmed from the USA PATRIOT Act such as the Financial Crimes Enforcement Network, which focuses specifically on money laundering and financial crimes. United Nations Security Council Resolution 1373 is a counter-terrorism measure intended to deny financing to terrorist organisations and individuals. Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act, also known as USA PATRIOT Act, was also enacted in 2001. In 2009 the act aided in blocking around $20 million and another $280 million that came from State Sponsors of Terrorism. In 2020, Veit Buetterlin, who conducted investigations on-site in more than 20 countries and who was kidnapped in course of his work, explained in an interview with CNN that the fight against terrorism financing will be an ongoing challenge (“it’s actually impossible to
