The US Treasury, represented by Scott Bessent, is expected to announce an expansion of secondary sanctions targeting entities and countries that maintain business relations with Iran, according to Reuters via FX Street.

This move aims to broaden the scope of financial and trade restrictions in an effort to increase pressure on Iran by limiting its international economic engagements.

For Japanese investors and markets, heightened US sanctions on Iran could influence regional trade dynamics and risk sentiment, particularly in sectors linked to energy and commodities.
