Asean, Japan, China, South Korea unite on oil supply risks amid Middle East crisis

The shock could become broader and more persistent
Finance ministers warned that prolonged Middle East conflict threatens to spread beyond energy into food, logistics, and tourism sectors.

In the ancient city of Samarkand, finance ministers from across Asia gathered to reckon with a disruption older than any of their institutions: the sudden severing of an energy lifeline. The Middle East conflict, having closed the Strait of Hormuz, reminded these export-dependent economies how fragile prosperity becomes when the arteries of global trade are cut. Their response — pledges of solidarity, supply chain diversification, and readiness to defend their currencies — reflected both the urgency of the moment and the hard-won wisdom of a region that has survived financial catastrophe before.

  • Iran's closure of the Strait of Hormuz has cut off the crude oil that Asian economies depend on as fundamentally as oxygen, sending growth forecasts down and inflation projections sharply upward.
  • The shock is already spreading beyond energy — logistics networks, food prices, industrial inputs, and tourism all face cascading disruption if the conflict is not contained.
  • Japan moved first and fastest, committing $10 billion in April to help regional neighbors secure oil and petroleum purchases, while finance ministers in Samarkand pledged collective action to diversify away from Middle Eastern supply.
  • China's absence from the table loomed large — Beijing has been quietly redirecting its own crude imports from Russia, Indonesia, and Brazil while restricting exports, moves that could distort global supply without any regional accountability.
  • Currency markets are already trembling: Japan intervened last Thursday as the yen slid toward 160 per dollar, and ministers warned they stand ready to act again as volatility threatens to compound the energy crisis with a financial one.

On a Sunday in early May, finance ministers and central bank governors from ten Asian nations convened in Samarkand, Uzbekistan, to confront a crisis none of them had engineered but all of them were absorbing. The Middle East conflict — and Iran's closure of the Strait of Hormuz following US-Israeli military operations — had cut off the crude oil that powers some of the world's most trade-dependent economies.

The joint statement they produced was measured but pointed. The escalation had "amplified downside risks to the regional outlook significantly," they warned, and the damage would not stop at energy markets. Prolonged conflict threatened to ripple into food prices, logistics, industrial supply chains, and tourism. The Asian Development Bank, meeting in the same city, had already revised its numbers: growth for developing Asia would reach only 4.7 percent in 2026, while inflation climbed to 5.2 percent — nearly two points above projections made just weeks earlier.

Japan had acted ahead of the summit, pledging $10 billion in mid-April to help regional partners secure crude oil and petroleum products through loans. The assembled ministers now committed to the longer work of diversifying supply chains away from the Middle East — reducing the structural vulnerability this crisis had so sharply exposed.

China's absence was conspicuous. Beijing sent no ministerial representative, having quietly pursued its own course: ramping up imports from Russia, Indonesia, and Brazil while restricting its own exports. The distortions this could create in global supply went unaddressed in the joint communiqué.

Currency pressures added another layer of urgency. Japan had intervened in foreign exchange markets on Thursday as the yen fell rapidly toward 160 against the dollar — a level with destabilizing regional implications. The Bank of Japan's decision to hold its policy rate steady in late April had weakened the yen further. Ministers pledged to remain ready to act against excessive volatility, a signal that intervention remained on the table.

The Asean-plus-three framework that brought them together was itself born from crisis — the 1997 Asian financial crisis taught the region that coordinated safety nets were not optional. Nearly three decades on, the same logic held. Whether the pledges made in Samarkand would prove sufficient depended entirely on what the Middle East did next.

In Samarkand, Uzbekistan, the finance ministers and central bank governors of ten Asian nations gathered on a Sunday in early May to confront a shared crisis: the Middle East conflict was strangling their oil supplies, and no one knew how far the damage would spread.

The closure of the Strait of Hormuz by Iran, following US-Israeli military operations, had created an immediate problem for economies that depend on Middle Eastern crude the way a body depends on blood. Japan's Finance Minister Satsuki Katayama, who cochaired the talks alongside the Bank of Japan's Deputy Governor Ryozo Himino and representatives from the Philippines, sat down with counterparts from across Southeast Asia, China, and South Korea to do what governments do in a crisis: acknowledge the threat and promise to act together.

The statement they released was careful but urgent. The escalation in the Middle East, they said, had "amplified downside risks to the regional outlook significantly." More than that, they warned of something harder to control: the ripple effects. If the conflict dragged on, the shock would move beyond energy markets into industrial inputs, logistics networks, food prices, and tourism. The Asian Development Bank, meeting in the same city, had already begun revising its forecasts downward. Growth for developing Asia and the Pacific would come in at 4.7 percent this year, down from earlier projections. Inflation forecasts climbed to 5.2 percent for 2026, up nearly two percentage points from estimates made just weeks before.

Japan had already moved. In mid-April, Tokyo had pledged $10 billion in financial support aimed at helping other Asian countries shore up their energy supply chains. The money would flow as loans to help nations purchase crude oil and petroleum products—a direct attempt to ease the immediate crunch. The finance ministers now committed to something broader: diversifying supply chains away from the Middle East, reducing the vulnerability that had made them so exposed to this particular crisis.

China, notably, sent no ministerial-level official to the talks. Instead, Beijing had been quietly moving on its own, boosting crude oil imports from Russia, Indonesia, and Brazil while restricting its own exports. Critics worried that China's massive purchases and export controls could distort global supply further, but the country's absence from the negotiating table meant those concerns went unaddressed in the joint statement.

The finance chiefs also signaled they were watching currency markets closely. Japan had intervened in foreign exchange trading on Thursday as the yen fell rapidly toward 160 against the US dollar, a level that threatened to destabilize regional economies. The Bank of Japan's decision to hold its policy rate steady in late April—a pause to assess the Middle East fallout—had weakened the yen further. The ministers now pledged to "stand ready" to respond to volatile currency swings, a diplomatic way of saying they would intervene again if necessary.

The Asean-plus-three framework itself carried historical weight. These meetings had begun in 1999, born from the wreckage of the 1997 Asian financial crisis, when nations learned that without coordinated safety nets, regional contagion could devastate entire economies. Central bank governors had joined the talks in 2012. Now, nearly three decades later, the same logic applied: act together or face the shock alone. The finance chiefs reaffirmed their commitment to a "rules-based, non-discriminatory, free, fair, open, inclusive, equitable, and transparent multilateral trading system"—language that sounded almost quaint given the fragmentation already underway, but language that mattered nonetheless. What came next would depend on whether the Middle East conflict stabilized or deepened, and whether the pledges made in Samarkand could translate into real protection for economies that had little margin for error.

Why does the Strait of Hormuz matter so much to these countries? It's just a waterway.

Model

It's the artery. About a third of all seaborne oil passes through it. When Iran closed it, they didn't just block a route—they made every Asian nation dependent on Middle Eastern oil suddenly vulnerable to a single chokepoint controlled by a hostile actor.

Inventor

So Japan's $10 billion—is that enough to fix the problem?

Model

It's a tourniquet, not a cure. The money helps countries buy oil on the spot market and diversify suppliers, but you can't replace Middle Eastern crude overnight. What it really signals is that Japan understands this could last a while.

Inventor

China didn't send a minister. What does that tell you?

Model

That Beijing is playing a different game. They're securing their own supply by buying from Russia, Indonesia, Brazil—locking in deals bilaterally. They're not interested in a coordinated Asian response because coordination means sharing, and they're in hoarding mode.

Inventor

The ADB downgraded growth forecasts. How bad is that?

Model

It's the canary in the coal mine. When a development bank starts cutting growth numbers and raising inflation forecasts weeks apart, it means they're watching something deteriorate in real time. They're not panicking yet, but they're preparing for worse.

Inventor

What happens if the conflict doesn't end soon?

Model

Then you get spillover. Food prices rise because shipping costs rise. Tourism collapses because people don't travel during uncertainty. Industrial production slows because supply chains break. The finance ministers know this. That's why they mentioned it—they're warning their own governments that this isn't just an energy problem anymore.
