US and Chinese Supply Buffers Absorbed 9.3 Million Barrels a Day of Hormuz Tightness Before the Ceasefire

US and Chinese Supply Buffers Absorbed 9.3 Million Barrels a Day of Hormuz Tightness Before the Ceasefire Morgan Stanley calculates that rising US exports and falling Chinese imports shielded global markets from the full force of the strait closure, but those buffers are depleting. ICE Brent crude front-month slid 11.7 percent and NYMEX WTI plunged 13 percent after President Trump announced what he called great progress in Iran talks. The moves were sharp but short-lived. Prices rose again on renewed hopes for a settlement, then fell once more as Trump pushed back a deadline for Iran to reopen the Strait of Hormuz. The pattern — conflicting White House signals producing violent two-way price action — has defined crude trading since the war began nearly six weeks ago.^2,5 The two-week ceasefire that followed brought a pledge of safe passage through Hormuz. But vessel tracking data told a different story. Commercial shipping through the strait slowed to a near standstill after a sharp escalation, with just one ship exiting the Gulf while two entered over the monitoring period. The physical reality of Hormuz transit has lagged diplomatic announcements consistently since the conflict started.^1,6 Morgan Stanley quantified the buffers that have prevented a worse outcome. The United States increased crude exports by 3.8 million barrels a day. China cut imports by 5.5 million barrels a day. Together, those two adjustments shielded the rest of the world from 9.3 million barrels a day of effective tightness. That is a very significant amount, the bank's analysts said, and it explains why futures failed to top 2022 levels despite the loss of almost 1 billion barrels of supply flow.⁴ The shielding effect is not sustainable. US export capacity has physical limits. Chinese import cuts reflect a strategic decision to draw down reserves rather than buy at elevated prices — a choice that works until reserves thin. Morgan Stanley warned the oil market is in a race against time, with the factors restraining prices standing to erode if the waterway stays closed into June.⁴ China's calculus is shaped by more than oil prices. Chinese elites do not agree on who may win from the war in Iran, the Economist reported. A short war would not hurt America enough, according to one line of thinking. The implication is that Beijing has been willing to absorb the cost of reduced imports partly because the conflict serves broader strategic interests — weakening Washington's position, elevating energy costs for European allies, and demonstrating China's leverage as the world's largest crude buyer.⁷ The US-China trade framework adds another dimension. The two countries agreed to a one-year deal setting American tariffs on Chinese goods at about 47 percent and Chinese tariffs on American goods at about 30 percent, according to Peterson Institute estimates. A summit in Beijing featured discussion of beef, soybeans and Boeings — the three categories that dominate China's appetite for American goods. The energy channel runs alongside the trade channel, and any deterioration in the broader relationship would reduce Chinese willingness to cooperate on Hormuz.³ Iran's own position is harder to read than either Washington's or Beijing's. Dr Pippa Malmgren, speaking on Macro Voices, noted that the sticking point in negotiations is not the Iranian nuclear programme in the conventional sense. China was Iran's ally, but what remained of the IRGC made decisions based on different calculations than those driving the diplomatic track. The gap between Iran's political leadership and its military structures means that a ceasefire agreed at the political level may not hold at the operational level in the strait.⁸ The airline sector is pricing in sustained disruption regardless of diplomatic signals. Lufthansa warned of increased ticket prices and flight cuts due to an expected 1.7 billion euro increase in its jet fuel bill. That kind of corporate planning decision is harder to reverse than a futures position and suggests the physical economy is preparing for an extended period of elevated energy costs.² For crude traders, the Morgan Stanley framework defines the near-term trade. The 9.3 million barrel-a-day buffer is the number to watch. If US export growth plateaus — and there are physical limits to how much more the US can ship — or if China resumes importing at anything close to pre-conflict levels, the cushion disappears and the full supply loss hits the market. The two-week ceasefire expiry is the immediate catalyst, but the structural question is whether Washington and Beijing continue to absorb the cost of keeping global oil markets artificially calm.
