Ghalibaf’s maths missile at Trump decoded: Is Iran fixing US interest rates?

What Happened

Iranian Parliament Speaker Mohammad Bagher Ghalibaf, who has been a lead negotiator in Tehran-Washington talks over the past six months, posted a version of the Taylor equation on X hours before the US Federal Reserve raised its benchmark interest rate by 25 basis points on Wednesday. In the post he wrote “Let’s see if a hike could open SOH or produce a single barrel” and “You can’t 25bp a chokepoint”, referring to the Strait of Hormuz, which Iran has effectively blocked for global shipping, and asserted that “It’s SOH risk premium, and We set it.” The same week, the Pentagon conceded that Iran’s missiles and drones had downed dozens of US aircraft, damaged or destroyed hundreds of US buildings at bases in the Middle East, and drained military inventories worth billions of dollars. The rate increase was the Federal Reserve’s first in three years. Fed Chairman Kevin Warsh said renewed fighting between the US and Iran, which pushed up petrol prices, helped convince Fed officials to support higher rates. Analysts quoted by Al Jazeera said the war has indirectly driven the hike via energy prices but rejected Ghalibaf’s claim that Iran is setting US interest rates. Chris Beauchamp, chief market analyst at IG Group, called the post “a spectacular bit of agitprop” and said the energy spike and rise in yields drove the Fed “into a corner with no way out”. Susannah Streeter, chief investment strategist at the Wealth Club, said there is “no denying” Iran’s retaliatory action across the Gulf region intensified energy supply concerns and hotter inflation forecasts, but that AI hyperscaler spending and strong domestic demand also factored in; Tehran had influence, not control. The US-Israeli war against Iran began on February 28.

Key Actors

Why It Matters

Ghalibaf’s taunt is propaganda, but it highlights a real strategic dynamic: the effective closure of the Strait of Hormuz has contributed to a US energy shock, higher petrol prices, and the Federal Reserve’s first rate increase in three years. Even though the Fed retains independent decision-making, the episode demonstrates Iran’s ability to apply indirect financial pressure on Washington by threatening a critical chokepoint. It also reflects how the US-Israeli war with Iran, launched on February 28, has merged military escalation with global monetary and oil-market instability, complicating the Trump administration’s economic and diplomatic options.

Watch For

Monitor the next Federal Reserve policy statement for any further increases in the benchmark rate, given Chairman Kevin Warsh explicitly linked renewed US-Iran fighting to the hike. Watch for US CENTCOM assessments of whether the Strait of Hormuz blockade remains “highly effective”, and for any confirmation or denial of direct US-Iran talks claimed by President Donald Trump. Oil price movements and any change in Iran’s posture toward Gulf shipping lanes will indicate whether Tehran can sustain the risk premium that Ghalibaf claimed to control.
