Military Pressure Without a Negotiating Partner
Axios reported that the Pentagon order prepares the military for a new large-scale operation against Iran. Reuters reported that Vance set a hard condition for peace: Iran must reduce its nuclear enrichment capacity. Vance admitted Washington does not fully understand how Iran makes decisions. After the killing of Supreme Leader Ali Khamenei, the authority of President Masoud Pezeshkian and Foreign Minister Abbas Araghchi is unclear in its logistics and tactics. Trump said his biggest problem is that no one knows who governs Iran, and economic sanctions and military strikes can no longer force a concession from a government that cannot deliver one, resulting in a war that can expand faster than it can end.
Oil Markets and the Hormuz Tax
The Strait of Hormuz carries about 20% of global oil trade and has remained functionally closed since March. Brent has held above $90 consistently since then and touched highs of $119.50, close to peaks during the Russian invasion of Ukraine. Morgan Stanley raised its 2026 Brent forecast to $80–$90 and called the shock persistent, a projection that now looks low. Saudi Arabia built the East-West pipeline and Red Sea ports to bypass Hormuz, but Houthi attacks make that route unsafe, forcing Saudi Arabia to send more oil back through the strait. Moving oil now carries a war cost that the world pays a tax on: energy, shipping, food, and manufacturing.
Inflation That Central Banks Cannot Ignore
U.S. inflation was at 4.2% in the May report, the highest in three years, as WTI fuel prices consistently held between $90 and $105. Dallas Fed analysis found the WTI spike added about 1.7 percentage points to annualized first-quarter inflation. The OECD raised its 2026 U.S. inflation forecast to 4.2%, and the IMF raised its global inflation forecast to 4.4%. Cleveland Fed data show one-year inflation expectations climbing from 2.5% in February. The Federal Reserve has started raising rates, and Boston Fed President Susan Collins warned that inflation above 2% is increasingly likely. BMO analyst Ian Lyngen said the energy market’s effect on interest rates has not weakened. Central banks must now choose between fighting inflation and protecting growth, and either choice raises costs for households and businesses.
Global Growth and Iran’s Collapse
The IMF cut its 2026 global growth forecast to 3.0%, 0.3 points below its January estimate and 0.4 points below what it would have predicted without the war. The World Bank expects the Middle East and North Africa to contract 2.1% in 2026 after expanding 3.3% in 2025. Five of eight oil-exporting economies in the affected group are expected to shrink, with Qatar facing the worst downgrade. UN estimates show that if Hormuz stays closed through the end of the year, global inflation could exceed 6% and growth could fall to 2%. UNCTAD expects global goods trade growth to fall from about 4.7% in 2025 to between 1.5% and 2.5% in 2026. Iran’s economy is in free fall after the rial fell from 1.5 million per dollar to more than 2.1 million per dollar, and the IMF expects a 5.4% GDP contraction, inflation is near 90%, and unemployment is rising.
America’s Fiscal Bill and the Bond Market
The Pentagon has already spent an estimated $25 billion on the Iran war, mostly on ammunition, and has requested more than $200 billion in additional war funding. The bond market has already priced it in and is strained by inflation and rate hikes, which could be the reason for a pause in escalation. The U.S. 10-year Treasury yield reached 5.34%, higher than in 2007, while the UK 10-year yield hit 5.5%, and French borrowing costs reached their highest since 2008. War spending, rising inflation, and higher interest rates now reinforce one another, toppling the debt domino. The Pentagon’s preparation for more strikes and Vance’s demand for deep enrichment cuts point to the same conclusion: Washington and Tehran are still choosing escalation over settlement, and the cost can only rise as time goes on.
