Every day, roughly 103-105 million barrels per day of crude oil are consumed. In order to meet that demand, an equal amount has to be produced. But the world’s oil doesn’t just teleport from production to consumption. Crude oil has to go through transportation and refining processes before it can be used to make the numerous fuels, plastics, medicines, fertilizers, detergents, lubricants, skincare products, synthetic fibers, asphalt roads, and other products that people use in everyday life. It’s safe to say that even if oil wasn’t used as fuel, it would still be essential to modern lifestyles. Indeed, this is a fact that has been recognized by many governments around the world, who have figured out that by limiting the transportation of oil, they can gain leverage over other countries that they would otherwise have no method of touching. Throughout history, this has happened numerous times: the Yom Kippur War OPEC oil embargo, the First Iranian Revolution oil crisis, Iraq, Kuwait, the Gulf War, and the list goes on.
The Middle East Chokepoint
If there’s anything to notice about the international community’s long and storied list of oil crises, it’s that most of them occur as a result of political turbulence in the Middle East. One of the most recent examples is the war in Iran. Just like with past conflicts, the United States’ decision to intervene in Iran has caused an oil crisis. That’s because the Middle East accounts for around 30 percent of modern global oil production, historically even more, and while pipelines like the Saudi Petroline exist, most of that oil is transported to ports in the Persian Gulf to be shipped out to refineries and manufacturers all over the world. As a result of geographic happenstance, around 20 percent of the world’s crude oil has to be shipped out to the Indian Ocean through the Strait of Hormuz, which is only around 20 miles wide at its narrowest point. This provides Iran with immense leverage and retaliatory power. Following U.S. strikes, the country decided to use naval mines to stop the transportation of oil through Hormuz. While global oil demand is still around 100 million barrels per day, oil supply has dropped to around 80 million.
The Safety Rails
The Saudi Bypass
Considering the amount of goods that rely on oil, this shortage could have been disastrous for the world economy, and could have even triggered a global recession comparable to 2008, but that’s not what happened. A few key safety rails played a role in preventing absolute catastrophe. The first safety rail was the Saudi Petroline oil pipeline, a critical pipeline that brings oil from the eastern Persian Gulf to the western Red Sea. This allows roughly 5 million barrels per day to bypass the Strait of Hormuz choke point. That still leaves a roughly 15 million barrels per day gap, which is still enough to cause a catastrophic economic crisis.
Emptying The Emergency Reserves
Thus comes the United States and the International Energy Agency, with all of their emergency reserves of oil, stockpiled for exactly this occasion. Together, they release around 2.5 million barrels per day. This brings the total gap down to 12.5 million barrels per day. That’s still enough to cause a massive global economic recession. But to save the global markets, in comes an international actor that nobody previously thought was an oil power: China.
The Unexpected Actor
Historically, the top oil powers were Saudi Arabia, the de facto leader of OPEC, Russia, which controlled massive pipelines for all of Europe, and the United States, which has become the world’s largest crude oil producer through shale oil and innovations in fracking. Countries like Venezuela have large natural reserves, but have been historically penalized and sanctioned by the Western world for various reasons, to the point where the global market doesn’t rely on them, so they don’t have much sway in the global oil price in terms of production. Iran is a special case because, while it is heavily sanctioned, it also has the ability to cut off the Persian Gulf’s oil production.
China’s absence from this list made it especially surprising when the country, which is the world’s largest oil importer, quietly cut back imports from around 12 million barrels per day to 8 million barrels per day. In the month of June alone, they had a nearly 40% year-over-year reduction in oil imports with no official reason why.
How China Absorbed The Shock
A 40 percent reduction in oil supply should be a death sentence for any modern economy, so how did China manage to survive? They did it through two key ways: first, they temporarily reopened some coal power plants. While this is certainly a step backwards for Beijing’s clean air initiatives, it helped China to rely less on oil for electricity. Second and more importantly, Beijing tapped into its tremendous oil reserves, estimated to be up to 1.4 billion barrels, much larger than the United States’ reserves, which hold around 700 million barrels. And China’s reserves could actually be much larger. The estimate is based on satellite imagery showing the above-ground tanks, which allows government agencies to make a rough guess at the amount of oil stored. China also operates dozens of massive underground caverns that are used as fuel storage facilities. Current estimates place the number of these caverns at over 40-60, but the true size and scale of these facilities will always remain a black box to observers, since China treats the size of its strategic petroleum reserve as a top-secret state issue.
Where The Oil Came From
Sanctions, SWIFT, And The Petrodollar
How did China get so much oil in the first place? Much of it comes from countries that the Western world has excluded. The global oil trade uses the Society for Worldwide Interbank Financial Telecommunication (SWIFT) system, the engine of the Petrodollar. Since SWIFT is subject to EU and US regulation, the Western world can cut off countries like Iran, Venezuela, and Russia from being able to sell their oil. Since these countries have a lot of oil and nobody to sell it to with US dollars, they turn to alternatives. One of those major alternatives is China, which buys approximately 3.5 billion barrels of crude oil per day from Iran and Russia alone, often at extreme discounts of around $15 per barrel.
Small Banks And Shadow Fleets
Instead of using the SWIFT system, which would allow the United States to monitor purchasing, these transactions happen using RMB in regional Chinese banks like the Bank of Kunlun. As an alternative to using mainstream banks such as the Investment and Commercial Bank of China (ICBC), the world’s largest bank, these under-the-table deals happen in smaller banks because they hold fewer assets in Western countries and have less exposure to US dollar clearing. Mainstream banks could face secondary sanctions as a result of interacting with sanctioned entities. The exchange of oil itself is often done through under-the-table means such as shadow fleets. Oil that is actually imported from Iran or Russia often switches between tankers multiple times on the way to China. The final oil shipments are mixed in with oil from other countries such as Brazil and Malaysia in an attempt to ‘launder’ the sanctioned oil. Due to this thorough laundering, it is unclear exactly how much oil China imports from sanctioned countries. Through this process, Iranian crude oil is often relabeled as Malaysian or Singaporean Blend. This is shown through China’s self-reported statistics, which reveal China imports more Malaysian crude oil than Malaysia actually produces.
Why? The Theories
The most important question for the whole world is why. Why did China decide to quietly reduce its imports of oil, largely to the benefit of its own rival, the United States? There is no official reason or explanation for this move, as with most decisions from the policy black box that is the Chinese government. However, there has been a lot of speculation.
Theory One: Recession Self-Defense
One of the leading theories is that the Chinese government knew it would be hurting itself if a global recession took place. This theory makes some sense as China has extremely weak domestic consumption, so its economy relies mostly on exports. Obviously, a global recession would mean less money in the international market for Chinese goods, so fewer exports for China. This theory starts to falter when we consider the comparable economic damages the United States would sustain. The United States has somewhat lost much of its domestic manufacturing base and is mostly reliant on foreign countries such as China for certain products. Since China produces many commodities in much larger quantities than the United States and Europe, China tends to benefit more from advanced manufacturing processes and economies of scale than its economic rivals. Even in a recession, Chinese manufacturers would be able to set lower prices than their domestic competitors. The US and EU wouldn’t be able to protect their domestic manufacturers without implementing tariffs, which would further reduce affordability and increase inflation for consumers. So when considering the greater detrimental effect that this theoretical recession would have on the US and EU, it is somewhat strange that China didn’t choose this option. In the grand scheme of things, China is also facing significant local government debt that is reaching disastrous levels in some provinces, while also facing enormous challenges regarding water management and desertification. Perhaps the government thought they wouldn’t be able to combat these crises with less revenue from exports.
Theory Two: The Taiwan Drill
Some experts have also speculated that this is Beijing’s way of testing their oil reserves and completing an economic ‘Taiwan drill.’ Around 80 percent of China’s oil passes through the Strait of Malacca, and in a Taiwan invasion scenario, it is highly likely that the US will try to close the Strait of Malacca to punish China. Beijing has accounted for this by steadily diversifying its energy sources and building up its strategic reserves, and that’s what this theory is about. Just like how schools do ‘fire drills,’ China is doing a huge ‘Taiwan drill,’ where Beijing is seeing if its plan to counteract a theoretical Strait of Malacca closure will succeed, and if there are any domestic concerns they forgot to address. Maintaining a functioning economy at home is obviously a major concern for Beijing if it were ever to attempt an invasion of Taiwan.
Theory Three: Midterm Interference
The final—and most unlikely—theory is that Beijing is trying to manipulate the US midterm elections. It has been statistically proven that voters largely disapprove of the Iran war. Without China stepping in to ease the global markets, the fallout from the Iran war would have likely been much worse in the United States. Republicans are already projected to lose their majority in the House of Representatives, but predicted to retain their majority in the Senate. Without China’s intervention, current projections could look very different, and might even have Republicans losing both the House and Senate by a wide margin, as consumers would face consequences much worse than what we currently experience. Beijing could be subtly helping the Republican Party because it doesn’t want Democrats to enact the War Powers Resolution, which would end the US war in Iran. There are a few reasons why Beijing would want the Iran war to continue: first, it would severely harm the United States’ global standing and soft power as the international community continues to turn against it; second, it diverts international attention away from other issues (perhaps Beijing is planning to begin something like a dam in the Himalayas upstream of major Indian river deltas); third, it depletes US reserves faster than China’s, which Beijing could have calculated was worth the minor short-term reserve sacrifice. While this is certainly the furthest stretch of all the theories, it could still be a possible motivation for China’s unconventional actions.
Or Maybe It Is Just Business
This is all just speculation, as nothing about this situation is known for certain. It is entirely possible that the world is just overthinking China’s move, and that the Chinese government is simply abiding by their philosophy of buying when prices are low and rationing when prices are high. Still, China’s decision to drastically decrease oil imports amid the ongoing conflict in Iran remains one that could have many possible justifications, which remain to be seen.
