The United States is moving to a new phase in its confrontation with Iran, shifting the center of gravity away from military strikes and toward economic pressure. Secretary of State Marco Rubio has told allies that Washington intends to rely on sanctions rather than force, and Treasury Secretary Scott Bessent has described the effort as the greatest financial offensive ever mounted against Tehran.

The backdrop to that campaign is an Iranian economy already under strain. The rial has weakened sharply, and one US dollar now trades for roughly two million rials, a level that has eroded the purchasing power of ordinary Iranians and reshaped daily life inside the country.

The strategy carries a central complication: China. Beijing is the largest buyer of Iranian oil, and much of Tehran's export revenue flows through Chinese purchases. Analysts note that any attempt to choke off Iran's oil income depends on cooperation, or at least acquiescence, from President Xi Jinping's government — cooperation that is far from assured given the broader state of US-China relations. Without it, the reach of American sanctions is limited.

For now, the Trump administration has held back from imposing so-called secondary sanctions, the measures that would penalize foreign companies and financial institutions for doing business with Iran. That restraint has coincided with movement on another front. Iran and Oman have opened talks aimed at managing traffic through the Strait of Hormuz, the narrow waterway through which a large share of the world's seaborne oil passes. Reports of a temporary arrangement between the two countries have eased some concern in energy markets, and oil prices extended their decline as the talks advanced.

The pivot to economic tools follows a period in which neither airstrikes nor negotiations produced the outcomes Washington sought. Whether financial pressure can succeed where those approaches did not is now the open question. Some observers characterize the new posture as a serious tightening of pressure through the machinery of the Treasury Department. Others are skeptical, describing the latest warnings as unlikely to force a change in Iranian behavior, particularly while Tehran retains buyers for its oil.

The debate reflects an uncertainty about leverage. Sanctions have inflicted measurable damage on Iran's economy over many years, yet the country has continued to export crude and sustain its government. The effectiveness of the current campaign will likely hinge less on the language coming from Washington than on the decisions made in Beijing and in the shipping lanes of the Persian Gulf.
