When the Strait of Hormuz Closes: How Geopolitical Shocks Reshape Crypto and Merchant Payments

On February 28, 2026, the United States and Israel launched coordinated strikes on Iran, killing Supreme Leader Ali Khamenei. Within hours, Iran retaliated with missile and drone attacks on Israeli territory and U.S. military bases across the Gulf. By March 2, the Islamic Revolutionary Guard Corps had closed the Strait of Hormuz to all vessel traffic. The chain reaction was immediate: oil supply severed, inflation expectations surging, the Federal Reserve’s rate-cut timeline demolished, risk assets in free fall, and cross-border payment networks under stress they were never designed to handle. If you accept payments across borders, especially in crypto, everything that followed matters to your business.

From missile strikes to your payment dashboard

Here is how seven days reshaped global commerce. On February 28, strikes began overnight. Bitcoin slid below $64,000 within minutes. By Sunday morning, $70 billion had been wiped from the total crypto market cap in a single hour. Over the next 48 hours, $350 million or more in leveraged positions were liquidated, with more than 150,000 traders caught on the wrong side. We break down that cascade in our analysis of $350M liquidated in 48 hours.

On March 2, Iran formally closed the strait. Tanker traffic dropped to near zero, with over 150 ships anchored outside rather than risk passage. Brent crude jumped 10 to 13 percent, pushing toward $100 per barrel. The closure threatened roughly 20 percent of the world’s daily oil supply alongside critical volumes of LNG, jet fuel, and LPG bound for Asian and European markets.

The energy shock went beyond oil. Qatar, one of the world’s largest LNG producers, halted operations after Iranian drone strikes hit its export facilities. Europe’s benchmark TTF natural gas contract surged from the low €30s to over €60 per MWh, nearly doubling in days, at a time when EU gas storage sat at just 30 percent capacity. Goldman Sachs warned that a monthlong disruption could drive European gas prices to €74/MWh.

For merchants, the transmission is direct. Higher energy costs feed into shipping, warehousing, and production. Inflation expectations spike, pushing back rate cuts that support consumer spending. And if you settle in BTC, your revenue just took a hit measured in thousands of dollars per coin. Each domino connects to the next. No payment method is immune, though some handle the stress better than others.

Bitcoin’s wartime report card: risk asset, not safe haven

The “digital gold” narrative took another blow. During the peak of the crisis, Bitcoin fell to roughly $66,000, a decline of about 3.5 percent from pre-strike levels. Bitcoin ETFs closed February with $3.8 billion in net outflows, the worst monthly hemorrhage since spot ETFs launched. Year-to-date outflows reached $4.5 billion across five consecutive negative weeks.

Contrast that with gold. The metal surged to an all-time high near $5,598 per ounce, confirming once again that it is the asset investors actually reach for when missiles fly. The divergence was stark. We explore why this pattern keeps repeating in our piece on the great divergence between gold and Bitcoin.

There is a nuance worth noting, however. Bitcoin rebounded to approximately $68,900 within days, and by March 4, spot ETFs had reversed course with $458 million in single-day inflows as institutional investors bought the dip. That recovery was faster and more orderly than anything we saw during the 2022 geopolitical shocks. Bitcoin is more resilient than it used to be, but it is still not a hedge. It behaves as a liquidity thermometer, crashing first in risk-off events, then bouncing when the fear subsides.

At its March low, BTC was trading roughly 50 percent below its October 2025 all-time high of $126,000. That drawdown is about more than the Iran crisis. It reflects a macro deterioration that we unpack in our analysis of why Bitcoin fails the inflation hedge test in 2026. The three crypto narratives that collapsed this year are explored in depth in our Fear Trade series.

Iran’s accidental proof: stablecoins are financial infrastructure

Perhaps the most revealing moment of the crisis came not from Wall Street but from Tehran. As U.S.-Israeli strikes hit, Iran’s central bank halted the USDT-toman trading pair, not to punish crypto users, but to prevent the rial from repricing in real time against a dollar-pegged stablecoin. Think about what that means: a central bank treated Tether as a systemically important price signal. You only shut something down if it actually matters.

Meanwhile, Iranian citizens were doing the opposite of what their government wanted. Blockchain analytics firm Elliptic reported that outflows from Nobitex, Iran’s largest exchange, jumped 700 percent within minutes of the first strikes, with $10.3 million in bitcoin flowing off exchanges as citizens rushed to preserve value. Iran’s crypto transaction volumes had already reached an estimated $8 to $10 billion in 2025, and the central bank itself had acquired at least $507 million in USDT, what officials called a “sophisticated strategy to bypass the global banking system.”

The FATF’s March 3 report added more pressure. The watchdog found that stablecoins comprised 84 percent of all illicit crypto volumes in 2025. But the same infrastructure that enables sanctions evasion also enables legitimate commerce in places where SWIFT access is unreliable. In 2025, stablecoins processed a record $33 trillion in transaction volume, a 72 percent increase year over year. During the Hormuz crisis, stablecoins moved value where traditional banking rails could not. We examine what this means for policy in our piece on the GENIUS Act meeting a real crisis, and for Iran specifically in Iran’s stablecoin lifeline.

The tariff dimension: when courts and presidents collide

The Hormuz crisis did not arrive in a vacuum. Eight days earlier, on February 20, the Supreme Court had struck down Trump’s sweeping IEEPA-based tariffs in a 6-3 ruling (Learning Resources Inc. v. Trump). The court found that the International Emergency Economic Powers Act does not authorize the president to impose tariffs. Chief Justice Roberts, writing for the majority alongside Justices Sotomayor, Kagan, Gorsuch, Barrett, and Jackson, noted that interpreting IEEPA’s “regulate” to include taxation “would render IEEPA partly unconstitutional.” The tariffs had raised more than $160 billion through February 2026.

Within hours of the ruling, Trump pivoted. He announced a 15 percent global tariff under Section 122 of the Trade Act of 1974, which permits temporary import surcharges of up to 15 percent to address balance-of-payments deficits. The catch: Section 122 measures expire after 150 days unless Congress extends them, and they must be applied uniformly. No targeting individual countries.

So merchants now face a double bind. Supply chains are physically disrupted by war while trade costs shift under a tariff regime with a built-in expiration date. Planning horizons collapse. A merchant sourcing goods from Asia faces Hormuz-related shipping delays, energy cost surcharges, and a 15 percent tariff that may or may not exist in five months. We explore the merchant implications of this ticking clock in Trump’s 150-day tariff clock, and the broader macro reset in our 2026 macro reset analysis.

What this means for merchants accepting crypto

If you run a business that touches cross-border payments, three practical realities emerge from this crisis.

Accepting BTC means accepting geopolitical volatility exposure. A merchant who received a $10,000 BTC payment on February 27 held roughly $9,650 in value by March 1. That is a 3.5 percent haircut in 48 hours, driven entirely by events outside your control. If you hold BTC on your balance sheet, you are implicitly long on geopolitical stability. Most merchants do not intend to take that position.

Stablecoin settlement breaks the oil-to-BTC transmission chain. When oil spikes, inflation expectations rise, the Fed delays cuts, liquidity tightens, and BTC drops. Stablecoins break that chain. A USDC or USDT settlement holds its dollar peg regardless of what Brent crude does. During the Hormuz crisis, stablecoin transfers continued uninterrupted while bank wires to Gulf states faced delays of days. For a deeper comparison of settlement options during crises, see our analysis of stablecoins vs SWIFT vs cards.

Non-custodial gateways eliminate counterparty risk during crises. When exchanges halt withdrawals, when banks freeze accounts, when governments shut down trading pairs (as Iran’s central bank did with USDT-toman), custodial solutions become liabilities. A non-custodial gateway like Aurpay routes payments directly to your wallet. There is no intermediary holding your funds, no exchange that can freeze your balance, and no single point of failure that a geopolitical shock can exploit.

The deeper pattern: every crisis accelerates payment innovation

History does not repeat, but its financial infrastructure rhymes. The 1973 oil embargo exposed the fragility of dollar-denominated trade settlement and accelerated the creation of SWIFT. The 2008 financial crisis revealed counterparty risk in the banking system and gave birth to Bitcoin. The 2020 pandemic made in-person payments impractical and drove a permanent surge in digital payment adoption. We trace this full arc in our piece on oil shocks and alternative settlement through history.

The 2026 Hormuz crisis may be what pushes stablecoin settlement into wider adoption. Not because stablecoins are perfect (the FATF report makes clear they carry serious compliance risks) but because they worked when the alternatives did not. Bank wires stalled. Card networks faced authorization delays in affected regions. SWIFT messages to Gulf correspondents backed up. Stablecoins settled in seconds, at a fraction of the cost, with no dependence on any single nation’s banking infrastructure.

The question for merchants is not whether to adopt crypto payments. It is which layer of the crypto stack matches your risk tolerance. BTC offers long-term appreciation potential but exposes you to wartime volatility. Stablecoins offer dollar stability but require regulatory clarity that is still evolving under the GENIUS Act. Non-custodial settlement gives you sovereignty over your funds but requires you to manage your own wallets. The right answer depends on your business, your corridors, and your appetite for the kind of risk that a single missile strike can trigger.

When trade routes close, your payment rails should not

Geopolitical shocks disrupt supply chains, currency markets, and traditional payment networks simultaneously. Aurpay’s non-custodial stablecoin gateway keeps your cross-border settlements moving — no banks, no intermediaries, no single point of failure. See how Aurpay works.
