The Iran War Revealed an Unexpected Shock Absorber: China

For more than two decades, strategists in Washington have viewed China’s dependence on imported energy as one of its greatest vulnerabilities. Beijing could become richer, stronger and more technologically advanced, the argument went, but it would remain hostage to the narrow sea lanes through which much of its oil flowed. In any future crisis, particularly one involving Taiwan, those arteries could be squeezed.

The recent conflict involving Iran may have forced a reassessment of that assumption.

When President Donald Trump abruptly pivoted towards de-escalation, many observers focused on military considerations or domestic politics. Some argued that Washington had achieved its immediate objectives and wanted to avoid a prolonged regional entanglement. Others pointed to Mr Trump’s political coalition, parts of which have long opposed another open-ended war in the Middle East.

Both explanations are plausible. Yet another, less discussed factor loomed ominously in the background: oil.

The prospect of a prolonged conflict raised fears of severe disruptions to global energy markets, particularly if fighting threatened the Strait of Hormuz, through which roughly a fifth of the world’s traded oil passes. Traders, shipping companies and policymakers braced for the possibility of an energy shock that could send crude prices soaring, reignite inflation and damage consumer confidence across the world economy.

The concern was hardly abstract. American strategic petroleum reserves had fallen to their lowest level in decades. Energy firms warned that inventories were tightening. Analysts openly discussed scenarios in which oil prices might remain above $150 a barrel for an extended period. For an administration that had made low inflation and cheap petrol central to its economic narrative, such an outcome would have been politically painful.

And yet the worst never happened.

Oil prices rose, but not catastrophically. Inflation expectations remained relatively contained. Financial markets proved surprisingly calm. The economic shock that many feared simply failed to materialise.

Why?

According to Javier Blas, Bloomberg’s influential commodities columnist, the answer may lie not in Washington, Riyadh or Brussels, but in Beijing.

His argument is striking. China, he suggests, acted as a shock absorber for the global economy. Rather than amplifying disruptions, it absorbed them. In doing so, it may have demonstrated that it has quietly transformed one of its greatest strategic liabilities into one of its greatest strengths.

From Vulnerability to Resilience

To understand why this matters, one must go back to 2003, when President Hu Jintao coined the phrase “the Malacca Dilemma”.

The term referred to China’s growing dependence on imported energy, much of which passed through the narrow Strait of Malacca between Malaysia, Indonesia and Singapore. The concern was straightforward: if geopolitical tensions escalated, hostile powers could potentially choke off China’s energy supplies.

For years, Western strategists considered this vulnerability a permanent constraint on Chinese power.

They may have underestimated Beijing’s response.

Over the past two decades, China has embarked on a systematic effort to reduce its exposure to precisely such disruptions. The strategy has been sprawling and, at times, appeared economically inefficient. Yet recent events suggest it was anything but.

The most obvious component has been stockpiling.

While America’s Strategic Petroleum Reserve is publicly documented, China’s reserves remain opaque. Estimates vary, but many analysts believe Beijing has accumulated emergency oil inventories approaching 1.4 billion barrels—the largest strategic stockpile in the world.

The precise numbers are unknown. The effect, however, is becoming clearer.

During the Iranian conflict, China appears to have drawn heavily on those reserves while sharply reducing imports. According to some estimates, Chinese seaborne oil imports fell by as much as 45% from recent averages. Historically, such a decline would have caused significant economic disruption.

This time, it did not.

Factories continued operating. Electricity generation remained stable. Economic growth slowed little.

China, in other words, endured an energy shock without transmitting it to the rest of the world.

The Rise of the “Swing Importer”

Mr Blas has proposed an intriguing concept: China may be becoming the world’s first true “swing importer”.

For decades, Saudi Arabia played a stabilising role in energy markets because it possessed spare production capacity. When prices rose, Riyadh could pump more oil. When demand weakened, it could cut output.

China may now wield an analogous power—not through supply, but through demand.

By reducing imports while maintaining domestic economic activity, Beijing effectively removed itself from competition for scarce supplies. The result was to ease pressure on global markets precisely when tensions were highest.

If this interpretation is correct, the implications extend far beyond commodities.

Energy vulnerability has long occupied a central place in Western thinking about China, particularly regarding Taiwan. The assumption has been that maritime pressure could cripple the Chinese economy.

The recent crisis does not invalidate that entirely. China remains a large importer of energy and would struggle in a prolonged blockade.

But it does suggest that Beijing is far more resilient than many observers previously believed.

Insurance, Chinese Style

China’s resilience is not the product of a single policy.

Its strategic petroleum reserves are only one layer of a much broader architecture.

Another is electrification.

The world’s largest electric vehicle market was built partly for environmental and industrial reasons. But from a strategic perspective, each electric car is also one less vehicle dependent on imported oil.

The same logic applies to power generation.

Although coal receives little admiration abroad, Chinese policymakers have long viewed it through the lens of national security. Vast domestic coal reserves provide electricity that is largely immune to maritime disruptions or foreign pressure.

At the same time, China has invested heavily in nuclear power, renewable energy and natural gas.

The objective has not been optimisation.

It has been redundancy.

Beijing has deliberately created overlapping systems capable of sustaining the economy under stress. Strategic reserves, coal, renewables, electric vehicles, pipelines and alternative trade routes all serve the same goal: resilience.

That logic also explains China’s investments abroad.

Over the past two decades, Beijing has expanded pipelines from Russia and Central Asia while developing ports and infrastructure across the Indian Ocean, a network often described as the “String of Pearls”. Facilities in Gwadar Port, Hambantota Port and Doraleh Multipurpose Port do not eliminate China’s vulnerabilities.

They merely ensure that no single chokepoint can bring the system to a halt.

In geopolitics, alternatives are a form of power.

Echoes of 2008

This is not the first time analysts have argued that China helped stabilise the world economy.

During the global financial crisis of 2008, Beijing launched one of the largest fiscal stimulus programmes in modern history. While Western economies contracted, China continued spending, importing and growing.

Its demand sustained exporters from Australia to Brazil. Its purchases of American debt helped stabilise financial markets.

Critics have since debated the long-term consequences of those policies, from industrial overcapacity to debt accumulation.

But few dispute that China’s actions helped prevent a deeper global downturn.

The Iranian conflict presents an intriguing parallel.

In 2008, China stabilised the world through demand.

In 2026, it may have stabilised the world through restraint.

Different mechanisms. Different crises. The same conclusion.

China’s economy has become so large that its decisions increasingly shape outcomes far beyond its borders.

An Uncomfortable Reality

For years, much of the debate in Western capitals has revolved around how China’s rise threatens the international order.

Yet recent history presents a more complicated picture.

Twice in less than two decades—in the financial crisis of 2008 and now during the Iranian conflict—China appears to have acted, intentionally or otherwise, as a stabilising force in the global economy.

That does not make Beijing altruistic.

Great powers rarely are.

China built its reserves for China. It diversified its energy supplies for China. It electrified its economy to strengthen China’s security.

But one of the defining characteristics of great powers is that policies designed for domestic resilience often produce global consequences.

The most important lesson of the Iranian crisis, therefore, may not be that China imported less oil.

It may be that Beijing demonstrated an ability to absorb a major geopolitical shock without amplifying it—and without suffering the economic damage that many once considered inevitable.

For more than twenty years, the Malacca Dilemma haunted Chinese strategic thinking.

The recent conflict suggests that Beijing may have gone much further in solving that dilemma than the outside world had realised.

And if that is true, then the balance of geopolitical power may be shifting in ways that are only now becoming visible.
