US Warns China Over Support for Iran, Oil Jumps

USO, the U.S. oil ETF, has surged sharply over the past month, with its latest close at $145.66 after touching $161.86 in September, far above its 50-day moving average of $136.84 and 200-day moving average of $114.37. The move underscores how fast traders are pricing in geopolitical risk when tensions around Iran escalate.

The crude rally has also been technically extended. USO’s RSI reading has fallen from overbought levels but remained elevated at 37.9 on Sept. 30 after hitting 91.0 earlier this month, while price remains well above its long-term trend line. That leaves energy markets vulnerable to sharp swings on any new sanctions, supply disruption or diplomatic escalation.

Chinese equities have not escaped the pressure. The FXI China ETF closed at $34.02 on Sept. 30, below both its 50-day moving average of $35.17 and 200-day moving average of $36.11, suggesting investors are still discounting growth and policy risk even as Beijing resists Washington’s pressure.

The immediate backdrop is worsening. Beijing has condemned U.S. sanctions on Iranian airlines, revived a defense agency tied to support for Iran and, along with Russia, vetoed a U.S.-backed UN resolution on monitoring Iran sanctions. At the same time, China is also pressing Tehran to restrain Houthi attacks, highlighting how Beijing is trying to balance strategic support for Iran with the economic risk of wider regional disruption.

That leaves markets focused on two questions: whether Washington expands sanctions and secondary penalties, and whether Beijing sees Iran as a bargaining chip or a line it is willing to defend. Oil traders, bank compliance teams and holders of China-sensitive assets will be watching for any follow-up from the White House, the State Department or Chinese officials in the coming days.
