[UK Tightens Sanctions on Iranian Banks, Joins US Economic Pressure Campaign Against Iran] Reported by Golden Finance, on September 24, the UK is tightening sanctions on Iranian banks, joining the US-led economic pressure campaign against Iran. The UK Treasury stated that future applications for new licenses by designated Iranian banks in the UK will be defaulted as rejected, and an existing general license allowing limited operations by Iranian banks will not be renewed after its expiration next month. Affected Iranian banks include Bank Sepah, Bank Melli Iran's UK branch, Bank Saderat, Persia International Bank, and Bank Tejarat. US Treasury Secretary Besent previously launched an economic pressure campaign against Iran, aiming to restrict Iran's connection to the global trade system. However, the UK emphasized that this measure is primarily a tightening of existing sanctions rather than the introduction of new ones.
