With Iran insisting on yuan payments for transit, the Gulf’s financial framework is under severe strain.
Everyone, stop – this is a war
Before February 2026, approximately 129 cargo ships crossed the Strait of Hormuz daily, transporting about one-third of the world’s seaborne crude oil and one-fifth of global liquefied natural gas. No other shipping lane holds such a critical portion of the planet’s energy resources within such a limited area; at its narrowest, the strait spans around 33 kilometers, with even tighter navigable channels. For nations including Saudi Arabia, the UAE, Kuwait, Qatar, Bahrain, and Iraq, Hormuz is far more than a mere route—it constitutes the only large-scale outlet for hydrocarbons, which represent between half and nearly all of these governments’ revenues.
Then everything changed.
The U.S.-Israeli airstrike against Iran on February 28, 2026, transformed this geographic dependency into a profound systemic vulnerability. By March 4, Tehran declared the strait “closed,” deploying naval mines, boarding vessels, and attacking ships in transit. Within days, maritime traffic plunged nearly 90%.
Though not a physical blockade per se, the closure was effectively insurance-driven. When war-risk insurers withdrew coverage or hiked premiums prohibitively, and crews refused to sail, passage became virtually impossible without most ships facing direct attacks. The Federal Reserve Bank of Dallas has pointed out that the gulf producers see no difference between a military blockade and an insurance-induced blockade: once storage fills up, production must stop.
These months have unveiled a transformed Middle East, reshaped trade connections, and altered future trajectories.
By mid-July 2026, there was no sign of calm. Talks between Washington and Tehran collapsed, triggering intensified conflict: CENTCOM targeted Iranian air defenses, coastal radar, and Bandar Abbas port, while Iran vowed to expand its campaign beyond the strait if its energy infrastructure continues to be attacked. The IMO Secretary-General warned shipowners against attempting transit, and President Trump’s brief proposal to impose a toll of 20% on cargo values—positioning the U.S. as the “guardian of the Strait”—demonstrated the shifting stance of hegemonic powers regarding the previously uncontested principle of Gulf maritime freedom.
Hormuz is revealed as a trigger: it doesn’t generate rentier vulnerabilities but accelerates them, compelling a reshuffle in global trade. In effect, Hormuz is inflaming the entire Middle East and beyond, directly striking the oil monarchies once viewed as oil superpowers and defenders of the petrodollar.
The paralysis of trade
Let’s analyze the developments step-by-step. Initially, the disruption hit logistics through the London insurance market rather than crude prices: war-risk premiums soared early, rendering shipping unprofitable well before Iranian assaults intensified. In early March, the British Maritime Trade Operations Center documented ten attacks on merchant vessels, including fatalities; by April, the IMO reported some 2,000 ships and 20,000 sailors trapped within the Gulf. Brent crude rose rapidly from about $72 per barrel at February’s end to over $84 within days, briefly topping $100 during peaks of tension, and remained persistently above $80 into summer.
Trade routes in the Gulf have shifted westward around ports beyond the strait. UAE’s leading retailers rerouted shipments through Fujairah and Indian Ocean terminals, absorbing increased transport expenses, while main Gulf port operators confront significant volume declines. Oman, co-sovereign over Hormuz waters, finds its traditional mediator role and alliance with Tehran challenged by the militarization of a passage it has long sought to keep neutral; meanwhile, ports like Duqm and Salalah, located outside the strait, are growing in strategic importance unprecedentedly. Control over Indian Ocean access has thus become a decisive advantage.
The second development concerns oil volumes and capacity constraints. Existing alternate infrastructure is insufficient: Saudi Arabia’s East-West pipeline to Yanbu and UAE’s Habshan-Fujairah line can jointly handle about 8.8 million barrels daily—less than half the 17 to 20 million barrels previously shipped through the strait every day. As a consequence, a peacetime production cut of historic proportions occurred. Between February and April 2026, Saudi output dropped from 10.11 to 6.87 million barrels per day, Iraq’s from 4.14 to 1.49, UAE’s from 3.39 to 2.02, and Kuwait’s from 2.58 to just 560,000, removing over nine million barrels daily from the global market from these four producers alone. The International Energy Agency marked this as the largest oil supply disruption ever—exceeding those in 1973 and 1979.
The crisis’s impact varies sharply. Thanks to their bypass facilities, Riyadh and Abu Dhabi managed to sustain substantial exports while profiting from soaring prices; Saudi oil revenues, for instance, peaked in March 2026 at levels unseen since October 2022, as price gains offset volume losses temporarily. Conversely, Kuwait, Qatar, Bahrain, and Iraq lacked alternatives and swiftly pared exports to minimal amounts. Qatar’s predicament is worsened by its LNG exports, which depend on specialized carriers with no alternative routes, causing ripple effects in the manufacturing sector. Iran’s retaliatory strikes hit over eighty energy-related targets in allied Arab monarchies, incurring estimated damages around $58 billion according to IEA and Rystad Energy.
Fiscal erosion is a pressing problem
The third and most profound effect hits state budgets. Saudi Arabia’s case is revealing: its December 2025 budget forecasted a $44 billion deficit (3.3% of GDP) for 2026, aligning with a consolidation strategy. Yet first-quarter results released in May revealed a 125.7 billion riyal deficit—nearly twice the annual forecast—driven by a 20% increase in public spending amid collapsing oil income. Since oil contributes roughly 54% of government revenue, prolonged conflict forces difficult decisions: halting Vision 2030 projects, increasing sovereign debt, or drawing upon reserves.
The International Monetary Fund confirmed this negative trend through three downward GDP revisions within six months: Saudi growth fell from 4.5% in January to 3.1% in April and then to 1.7% in July, with a rebound to 5.5% in 2027 depending on the strait reopening. The region’s overall growth forecast dropped to 0.7%. National predictions illustrate vulnerability tiers: Qatar contracting 14.7%, Kuwait 4.2%, Bahrain 3.8%, UAE 1.9%, and Saudi Arabia 1.4%. This landscape indicates that economic recession severity correlates with proximity to bypass infrastructure. At a micro level, supply disruptions have driven UAE inflation to a 15-year peak, while Saudi Arabia witnessed a spike in bankruptcy filings—mainly in retail and construction sectors in Q1.
The fourth aspect deals with financial flows. Gulf sovereign wealth funds, totaling roughly $5 trillion amassed over decades, have long been the model’s safety net. However, the crisis exposes operational limits: much of their assets are tied to illiquid or strategic sectors such as tech, real estate, and private equity. To cover deficits, converting these into cash means selling amid adverse markets or shelving diversification objectives. Kuwait exemplifies this paradox: its General Reserve Fund’s liquid assets are nearly depleted, while its Future Generations Fund remains inaccessible to public budgets absent debt legislation. Hidden liabilities also exist—for example, bond issues by Saudi Arabia’s Public Investment Fund (PIF) and Aramco don’t appear in public debt figures but would represent obligations in crisis scenarios.
Markets reflect these shifts. In early March, Qatar’s index dropped 4.3% in one session, Gulf sovereign bonds sold off broadly, and Bahrain’s credit default swaps—on record-high public debt ratio at 152.4% of GDP—widened nearly 40%, the region’s steepest move. While bond prices partially recovered during the spring lull, credit conditions remain tight, and resumed fighting in July reignited uncertainty. The Gulf Cooperation Council currencies, excepting the Kuwaiti dinar, are pegged to the U.S. dollar; defending these pegs amid capital flight demands ample dollar reserves. Notably, the UAE’s Commerce Minister disclosed talks with Washington over a currency swap line to secure low-cost dollars for the dirham—revealing that monarchies which for decades parked surpluses in U.S. Treasuries are now seeking liquidity they once exported.
The entire petrodollar crisis
The fifth dimension is monetary and systemic. Since 1974, Gulf crude oil priced in dollars and reinvested surpluses in U.S. markets have underpinned American monetary dominance. The Hormuz crisis strikes at this system’s core. Tehran has imposed a selective transit regime allowing few “friendly” countries’ tankers to pass only if cargo payments and transit fees—up to two million dollars—are made in yuan or stablecoins. Although these volumes are small and should not be overinterpreted as an end to the petrodollar, this precedent links navigational security directly to invoice currency—a connection BRICS+ communiques never established. Existing trends—bilateral currency deals, yuan’s growing role in energy trade, and discussions on alternative settlement methods—have gained tangible momentum from the crisis, as acknowledged even by mainstream outlets.
The oil monarchies face a stark dilemma: their wealth is dollar-denominated, invested largely in Western assets and protected by U.S. security guarantees. Yet this protection failed to keep the strait open, while the now-withdrawn U.S. toll proposal raises concerns that security might become a tool for exploitation. Meanwhile, their primary energy buyers are increasingly Asian: prior to closure, roughly 91% of Gulf oil and products were destined for Asia, with China receiving around one-third of its imports through Hormuz.
This trade dynamic pulls toward the East, while the financial structure anchors them in the West. Remember this firmly.
Efforts to fund reconstruction and bypass projects domestically will likely reduce sovereign wealth fund capital outflows to Western markets, partly reversing the fifty-year capital recycling underpinning Atlantic finance.
The stress test
So far, the Hormuz crisis has not toppled any Gulf monarchy, and forecasts for a recovery by 2027 remain optimistic if the strait reopens. Yet the critical issue is less about survival than the shape and cost of what follows.
Initial analysis is unambiguous. The conflict exposed the fragility of oil revenues reliant on a corridor whose security monarchies don’t control; revealed that long-accumulated financial buffers are less liquid than assumed; demonstrated that the dollar peg, once a stabilizing anchor, can become a vulnerability; and showed that economic diversification promises through Vision programs remain primarily funded by the very oil income they aim to replace. The full consequences of the shutdown will emerge in late 2026 as reserves dwindle and fiscal inflows dry up.
Ultimately, this crisis tests not just the financial soundness of the oil monarchies but also the historic bargain sustaining them—the equilibrium of domestic wealth distribution and external security. Trade disruptions have cut volumes; financial shifts are eroding margins; and monetary changes threaten, over time, the very framework underpinning their wealth.
These trends were long brewing; the Strait of Hormuz has merely accelerated their arrival. In this sense, Hormuz is less the origin of the oil monarchies’ crisis than its revealer. Once again, it has set aflame the oil wells fueling the U.S. dollar and its allied monarchies.
