Iran-Israel Conflict Escalates: Threats to Global Financial Systems and Energy Security

The conflict between Iran and the United States, alongside Israel, is intensifying, with Iran now expanding its threats to target entities financing the U.S. Military. This escalation introduces a latest dimension to the conflict, potentially impacting global financial systems and energy security.

Iran Targets US Financial Institutions

Mohammad Bagher Ghalibaf, Speaker of the Iranian Parliament, stated on social media that financial institutions linked to the U.S. And holding American government bonds would be considered legitimate targets, alongside military bases. He argued that purchasing U.S. Government bonds equates to financing attacks on the Iranian people. CNBC reported on this development on March 23, 2026.

Ghalibaf further asserted that entities financing the U.S. Military budget are similarly legitimate targets.

US Ultimatum and Israeli Support

This warning followed a 48-hour ultimatum issued by U.S. President Donald Trump to Tehran on Saturday, March 21, 2026, demanding the reopening of the Strait of Hormuz, a critical route for global energy commodity logistics. Times Now reported on the escalating tensions.

Failure to comply with the ultimatum carries the threat of attacks on Iran’s power plants. Israeli Prime Minister Benjamin Netanyahu publicly voiced his support for the U.S. Threat, stating that Israel and the U.S. Are acting in full coordination. He also called on world leaders to join the effort, citing Iran’s potential to target European countries. Council on Foreign Relations provides background on the ongoing confrontation.

Iranian Retaliation Threats

Iran has responded by threatening to completely close the Strait of Hormuz and attack energy infrastructure and desalination facilities in the Gulf if the U.S. Proceeds with its ultimatum. Ghalibaf warned that any attack on Iran’s power plants would trigger retaliatory strikes on energy and oil infrastructure across the region, potentially causing long-term damage and driving up oil prices.

Escalating Military Activity and Energy Market Impact

Military activity has increased, with reports of intense missile activity targeting Israel, prompting warnings for residents to seek shelter in Jerusalem and central Israel. CBS News reported on Israeli strikes on Tehran on March 20, 2026.

Iran has effectively closed the Strait of Hormuz to most ship traffic since the U.S.-Israeli attack on February 28, 2026. This disruption has already pushed oil prices higher in recent weeks, raising concerns about supply disruptions, inflation, and economic growth. Brent crude rose 0.44% to $112.68 per barrel as of 22:57 EST on March 23, 2026, even as West Texas Intermediate (WTI) increased 0.78% to $99 per barrel.
