The Sanctions Narrative Blames Trump for the Rial's Collapse - but the Liquidity Data Points Elsewhere

The easy story is that US sanctions are destroying the Iranian rial. And on the face of it, the timing makes the headline look plausible.

The rial is 1.936 million per dollar as of today, August 1st, after the dollar set a record 1.941 million on July 18. In April 2025 it was around 811,000. After Trump's first maximum pressure campaign began in 2018, the rial lost over 90% of its value; before the 1979 revolution it had traded at about 70 rials per dollar.

The sanctions narrative is the easy story. But if you look at the liquidity mechanics - the same mechanics that drive every currency on the planet - the rial's collapse is a textbook lesson in what happens when a central bank prints without anchor. Sanctions and war are the accelerant. Domestic money creation is the fuel.

Iran is one of the few places on Earth where you can still watch the liquidity cycle in its rawest form. It's the mechanism that runs all asset prices and all currencies, just compressed into a single economy you can observe in real time.

The Money Supply Tells the Real Story

Iran's broad money supply - M2 - hit 131,845 trillion rials by November 2025, with a 12-month growth rate of 40.4%. That figure comes from analysts tracking the Central Bank of Iran's own data. If you hold a money supply growing at that pace and your real economy is contracting by an estimated 6.1% this year per IMF projections, the currency doesn't so much depreciate as it evaporates.

The transmission mechanism is mechanical: more rials chasing fewer goods, with trade channels already choked by a US naval blockade on the Strait of Hormuz. The result is inflation that hit 88.6% in June 2026 - the highest level since the Second World War, according to official data cited by multiple outlets.

The head of the Central Bank of Iran himself said the root of the country's economic challenges is "excessive money supply caused by domestic banks' heavy borrowing from the central bank." That is the Iranian central banker's own diagnosis. Not the sanctions. The money printer.

For decades, Iran's response to fiscal pressure has been the same regardless of administration: print. The government of Rafsanjani, known for pro-market policies, printed. Ahmadinejad's populist government printed. Rouhani printed. The current regime prints. It's not a political choice - it's a structural one. The banking system is loaded with nonperforming loans, many tied to political lending that never gets repaid. The central bank lacks the independence or authority to stop the cycle. So it prints.

Sanctions as the Multiplier, Not the Cause

Let's be clear: sanctions absolutely matter. They're not a side note. But they work through the liquidity channel.

When you cut off a country's access to foreign exchange - particularly when oil exports, which used to fund 60% of the government budget, are choked by sanctions and now further disrupted by a US naval blockade that began in April 2026 - you destroy the inflow that would normally offset domestic money creation.

In a normal economy, you can print money and offset the pressure by earning foreign currency through trade. Iran can't. Non-oil trade fell about 29% month-on-month in the final month of the Iranian calendar year (ending March 20) in connection with the war that began February 28. Government estimates put wartime damage at $300 billion. Ports, industrial zones, power stations - systematically degraded.

So you have a money supply growing at 40% on the domestic side, and a foreign currency inflow that has been structurally constrained for decades and then catastrophically compressed by war. The arithmetic is brutal.

The timeline confirms the interaction. When the war started on February 28th, the dollar spiked to 1.72 million rials. During the active conflict, demand for foreign currency temporarily softened as economic activity froze, and the dollar actually pulled back to around 1.46 million. It was the resumption of economic activity - combined with the $300 billion damage bill and the government's need to import essentials - that pushed the dollar back toward 1.9 million.

A brief memorandum of understanding in June restored enough confidence to send it back to 1.53 million. Then renewed tensions and a fresh naval blockade sent it higher again. The currency moves with the expected flow of dollars into the country. That's the sanctions transmission channel.

But without the 40% M2 expansion underneath, the pressure wouldn't have been this catastrophic.

What This Looks Like at Human Scale

The numbers aren't abstract. At the current open-market rate, Iran's official monthly minimum wage of 166 million rials is worth about $86.

In late April, reporters were hearing from laid-off workers in petrochemical plants reducing food consumption to one meal a day. Seizure medication prices had more than tripled. By May 2026, many workers were unable to afford simple foodstuffs such as bread. The internet blackout, then stretching into its third month, had cut off freelance and e-commerce income for millions.

The IMF expects the economy to contract 6.1% in 2026. The World Bank projected 1.7% contraction in 2025 and 2.8% in 2026. As of March 2025, between 22% and 50% of Iranians were estimated to be living below the poverty line.

This is what happens when the liquidity cycle turns against you at the domestic and international level simultaneously. It's the same mechanism that affects every currency on the planet - just compressed into a single, hyper-visible case study.

The Bigger Picture

The maximum pressure narrative credits the collapse to Trump's sanctions. The sanctions are real and their impact is severe. But the rial was already on a multi-decade trajectory of collapse long before the US returned to maximum pressure. The money printer was already running.

What Iran demonstrates - and what this analysis has argued for years in the context of global markets - is that liquidity is the master variable. When money supply expands without a corresponding increase in productive output or foreign exchange inflow, the currency falls. Period. It's the same relationship that connects Fed Net Liquidity to Bitcoin, that connects central bank balance sheets to equity valuations, that connects credit creation to asset prices across every market.

Iran is just the version where you can see it clearly.

What to watch: Iran's M2 growth rate in the next available data release. If it stays above 35-40% year-on-year, the rial's trajectory remains structurally downward regardless of diplomatic developments. Watch also for whether the US blockade tightens further around the Strait of Hormuz - that's the external liquidity valve. And watch inflation prints: if they sustain above 80%, the domestic currency demand will continue to collapse as Iranians convert to dollars, gold, or crypto to preserve any remaining savings.

The liquidity cycle doesn't care about press conferences.
