US Treasury urges world to join sanctions on Iran as G7 finance ministers meet in Paris
US Treasury Secretary Scott Bessent on May 18, 2026 urged international partners to join the United States in imposing sanctions on Iran, calling on “the world” to act as G7 finance ministers convened in Paris for a two-day meeting amid growing economic turbulence. The move to press for coordinated sanctions on Iran comes against a backdrop of market volatility and geopolitical tensions that officials say complicate efforts to stabilise global finances. Delegates meeting in Paris signalled that security and economic policy are increasingly entwined in the G7 agenda this week.
G7 finance ministers convene in Paris for two-day talks
G7 finance ministers arrived in Paris on May 18 for a scheduled two-day meeting intended to address both macroeconomic challenges and geopolitical risks that are weighing on global growth. The Paris agenda includes inflation, debt vulnerabilities in emerging markets, and coordination on financial measures tied to national security concerns. Officials described the gathering as a timely forum to align policy responses as supply shocks and regional conflicts strain markets.
Treasury chief frames sanctions push as collective security measure
Scott Bessent framed the appeal for broader sanctions on Iran as part of a collective effort to deter destabilising behaviour and to protect global financial systems. He told delegates he was contacting allies and partners to seek a wider coalition, arguing that unilateral measures would be less effective than coordinated action. By stressing shared responsibility, the Treasury sought to link economic penalties with diplomatic pressure in pursuit of a unified response.
Diplomatic and legal hurdles to a wider sanctions coalition
Experts at the meeting acknowledged practical and legal hurdles to quick adoption of expanded sanctions on Iran, including differing national risk tolerances and legal frameworks for financial penalties. Some G7 members weigh potential secondary impacts on international trade and the energy market, and several finance ministries signalled the need for careful calibration. The process of building consensus is expected to involve detailed legal work and consultations with private-sector banks and clearing houses.
Market and energy implications for the Gulf and global supply chains
Analysts warn that a coordinated sanctions regime targeting Iran could tighten energy markets and raise costs for import-dependent economies, with ripple effects for Gulf states that are both producers and major trading hubs. Financial market volatility may increase in the short term as investors price geopolitical risk, affecting currencies, bond yields, and commodity prices. Finance ministers told delegates they would monitor near-term market responses while considering measures to mitigate spillovers to vulnerable economies.
Treasury outlines tools and enforcement mechanisms under consideration
Washington signalled it would pursue both traditional financial sanctions and targeted measures designed to disrupt illicit revenue streams, while emphasising enforcement coordination with international partners. The Treasury pointed to mechanisms such as asset freezes, restrictions on correspondent banking, and trade-related curbs as potential tools, though officials said scope and timing would depend on allied buy-in. Private-sector compliance and enforcement capacity were highlighted as critical to ensuring any sanctions were effective and legally defensible.
G7 outcomes could shape next diplomatic steps and international pressure
Delegates in Paris indicated the summit’s communiqué may reflect heightened language on Iran and an intention to explore multilateral measures, but cautioned that formal commitments would depend on subsequent diplomatic work. Finance ministers are expected to task working groups with drafting technical proposals and assessing economic impacts before any coordinated action is announced. Observers said the coming days and weeks will be crucial for translating political intent into operational plans.
The Paris meeting underscored how finance ministers are increasingly addressing security-related economic risks alongside more traditional monetary and fiscal issues, with calls for broader sanctions on Iran taking centre stage in discussions. As officials move from statements to technical planning, the international community will watch for concrete steps that balance enforcement with efforts to limit disruption to global markets and humanitarian channels.
