The Iran file, once a smoking ember of diplomatic miscalculation, has been reignited with the raw heat of policy reversal. Donald Trump, in his characteristically combative style, tore up the Obama-era nuclear deal, the Joint Comprehensive Plan of Action (JCPOA), as though it were a bad quarterly report. The contrast is not merely stylistic: it is a fundamental clash of market strategies. Obama approached Iran as a long-term bond, yielding slowly with interest payments of sanctions relief. Trump, by contrast, treated it as a distressed asset, a short that needed to be covered by maximum pressure.
Obama’s strategy was built on multilateralism. He assembled a syndicate of investors: the UK, France, Germany, Russia, China, and the EU. Together they structured the JCPOA, a complex derivative designed to cap Iran’s enrichment for 15 years in exchange for the removal of financial shackles. The market seemed to like it: oil volatility settled, and Iran’s GDP grew by over 7% in 2016. But the underlying collateral was suspect. The deal had opaque clauses on ballistic missiles, inspections of military sites, and the snapback of sanctions was a weak covenant.
Trump, the former real estate developer, saw a bad property. He argued the deal was a negative cash flow asset, bleeding American credibility and enriching a regime that funded proxies across the Middle East. In May 2018, he pulled out. No consultation, no phased exit. He tore up the contract and reimposed sanctions, hitting Iran’s oil exports like a short squeeze. The effect was immediate: Iran’s oil exports collapsed from 2.5 million barrels per day to under 500,000. The rial depreciated by over 60%, inflation soared past 40%, and the Tehran stock exchange tanked.
The market response was telling. In Obama’s tenure, the S&P 500 rose steadily, but oil prices dropped sharply, hurting energy stocks. Under Trump, energy stocks rallied, but volatility spiked. The VIX, the fear index, jumped each time Trump threatened Iran. Investors disliked uncertainty. But Trump’s bet was that squeezing Iran would force a better deal. It did not. Iran resumed enrichment, surpassing JCPOA limits, and the region saw attacks on tankers and the killing of General Soleimani.
Where Obama saw diplomacy as a risk management tool, Trump saw it as a sign of weakness. He wanted to renegotiate from a position of strength. But in finance, there’s a term for that: a leveraged buyout. You borrow heavily, squeeze the target, hope for a quick flip. The problem is that if the deal doesn’t materialise, you are left with a debt-laden, distressed asset. Trump’s maximum pressure campaign isolated Iran but also alienated allies. The Europeans set up INSTEX, a payment mechanism to bypass US sanctions, but it never really worked. The market for Iranian trade evaporated, but so did any prospect of a new nuclear accord.
Now, the next administration inherits a mess. Obama’s path was multilateral, incremental, and transparent. Trump’s was unilateral, aggressive, and opaque. Which was more effective depends on your discount rate. If you believe in short-term gains from reduced oil prices and limited conflicts, Obama’s method was better. If you think the JCPOA was a defective product that needed a total recall, Trump’s approach has a logic. But the bottom line is that both strategies failed to deliver a stable, long-term solution. Iran’s nuclear programme is more advanced, the region is more volatile, and the US has lost credibility with both allies and adversaries. The balance sheet is in the red. The real test will be whether the current White House can find a third way, one that blends the best elements of both without the worst. But given the current fiscal climate and the attention on Ukraine, do not bet the house on a quick fix. The Iran file remains a high-risk, low-yield investment.
