An $18.5 billion bid by a Chinese energy company to acquire the American gas and oil firm Unocal has sparked a strong but misguided reaction on Capitol Hill. On June 30, the House passed a resolution by 398 to 15 expressing national security concerns about the acquisition of Unocal by the China National Offshore Oil Corporation (CNOOC), an energy company 70 percent of which is owned by the Communist government of China. On July 13, the House Armed Services Committee held a hearing that raised the decibel level several notches, with members especially vocal about the impact of the proposed deal on America’s “energy security.”

But fears that such a transaction would harm national security by making the United States more dependent on foreign oil or that the proposed transaction threatens to somehow provide China with an “oil weapon” are ill-founded. In short:

Energy independence provides no economic protection against supply disruptions abroad and no guarantee that supplies will be secure in the future. America’s vulnerability to oil supply disruptions is primarily related to how much oil we consume, not where the oil we consume happens to originate.

America need not worry about access to international oil supplies. Embargoes or supply diversions cannot keep oil out of U.S. ports, and there are plenty of sellers in world oil markets. Only a naval blockade could prevent America from buying all the oil it needs from international oil markets.

Unocal’s reserves are not large enough to provide CNOOC with significant market power in the global oil economy.

Because China is a net oil importer, it has every incentive to maximize production and none to curtail production. Accordingly, American and Chinese interests in the oil market coincide.

Dependence on Foreign Oil Is Not an Economic Problem

It’s doubtful that American oil imports would increase as a consequence of a CNOOC-Unocal merger. That’s because Unocal’s domestic oil assets are small (58,000 barrels of oil production a day, which translates into 0.8 percent of U.S.production from petroleum liquids and 0.3 percent of to U.S.petroleum consumption)1 and are most profitably sold to the U.S. market.

Even were Unocal’s U.S. oil assets diverted elsewhere, it would have no effect on America’s vulnerability to oil supply disruptions abroad. That’s because it makes no difference from an economic standpoint whether the oil we consume is produced domestically or from foreign sources.2 Moving oil around the globe is so cheap and easy that a shortage of oil anywhere in the world increases the price of oil everywhere in the world. That’s why the oil price shock set off by the Iranian Revolution in November 1978, increased the price of oil in Great Britain just as much as it increased the price of oil in Japan. It didn’t matter that Great Britain was energy independent at the time and that Japan was 100-percent reliant on imports. The only way to render America invulnerable to oil supply disruptions abroad would be to stop using petroleum products altogether or, alternatively, ban all imports and exports of oil, gasoline, and the like.

Moreover, removing our economy from international energy markets in a quest for independence would make America more vulnerable to supply disruptions for two reasons. First, it would be easier for terrorists to disrupt energy production if the sources of supply are geographically concentrated rather than dispersed. Second, if a domestic disruption were to occur and a trading infrastructure were not in place, we would not be able to avail ourselves easily of supplies elsewhere.

Finally, oil imports do not increase the pressure on oil prices. Rather, they relieve the pressure. America imports oil because it’s cheaper than producing that oil here at home. Trade reduces domestic prices for all services and commodities.

Physical Access Is Not a Problem

The pre-OPEC oil market was characterized by longterm contracts between producers and consumers with little oil available in secondary markets. Accordingly, physical access might once have been a reasonable concern.3 The modern oil market, however, has been radically transformed. Robust spot and future markets exist for oil and refined petroleum products. Long-term contracts are rarer, and contract prices are relatively transparent. Accordingly, physical access is no longer a legitimate concern for consuming nations.4 As Richard Gordon, professor emeritus of mineral economics and former director of Pennsylvania State University’s Center for Energy and Mineral Policy Research, puts it: “Basic economics indicates that no shortages will arise as long as prices are uncontrolled. The question is the price needed to eliminate the shortage.“5

That explains why any diversion of Unocal production toward Chinese domestic markets is irrelevant from an economic standpoint. Unocal production redirected towards China would simply displace imports from other suppliers. Those displaced imports would re-enter the world market with no net effect on global supply.

That also explains why an oil embargo against the United States is incapable of preventing oil imports from reaching U.S. ports. Once oil leaves the territory of a producer, market agents dictate where the oil goes, not agents of the producer. The globalization of oil markets ensures that the United States will always have access to oil, whether oil producers like it or not.6

The 1973 oil embargo proves the point.7 As MIT’s Thomas Lee, Ben Ball Jr., and Richard Tabors observe regarding that experience, “It was no more possible for OPEC to keep its oil out of U.S. supply lines than it was for the United States to keep its embargoed grain out of Soviet silos several years later. Simple rerouting through the international system circumvented the embargo. The significance of the embargo lay in its symbolism.“8 Granted, “there wereshort-term supply disruptions,” but “the only tangible effect of the embargo was to increase some transportation costs slightly, because of the diversions, reroutings, and transshipments necessitated.“9

MIT oil economist M. A. Adelman agrees: “The ‘embargo’of 1973â€â⒬œ4 was a sham. Diversion was not even necessary, it was simply a swap of customers and suppliers between Arab and non-Arab sources… the good news is that the United States cannot be embargoed, leaving other countries undisturbed.“10

Unocal Provides Little Ammunition for an “OilWeapon”

Unocal is a relatively minor player in world crude markets. Its worldwide operations produced a total of 169,000 barrels of petroleum liquids in the first quarter of 2005,11 or 0.23 percent of global oil production.12 Accordingly, CNOOC would not gain any real market power in world oil markets were it to acquire Unocal.

Some have expressed concern that China hopes to gain such market power through the incremental acquisition of reserves and through concessions for development rights from producer states. Although we cannot discern with certainty what Chinese intentions might be, we should recognize that there are simply not enough non-OPEC reserves available to CNOOC to challenge OPEC’s position as the marginal producer in world oil markets–the position that brings with it market power. Concessions from producers do not translate into control over oil assets, as both the United States and Great Britain discovered to their chagrin between 1960 and 1980.13

The fact that China is a net importer of petroleum means that the Chinese economy is best served by low oil prices. If we posit that the Chinese government is interested in a stronger and not a weaker Chinese economy, we can safely assume that Chinese control of oil assets will result in maximum production.

This is important because the only sense in which an “oil weapon” can be said to exist is in the economic damage that can be done to consuming nations by a supply reduction engineered by producers. Accordingly, were the Chinese government–through CNOOC or whomever–to deploy an“oil weapon,” its use would harm the Chinese economy as much if not more than it would harm the United States economy. That’s because it requires more oil to produce a unit of GDP in China than in the United States and because the Chinese economy is less able to efficiently adjust to price shocks than is the United States economy.14

Relatedly, if the Chinese tried to hoard oil to keep it out of American hands (either by stockpiling inventory or shutting down production), it would drive up oil prices for consumers everywhere–Chinese and American alike–and do more harm to the Chinese economy than to the American economy. Simply put, deployment of a Chinese “oil weapon” would backfire on the Chinese.

Conclusion

A reasonable understanding of how international oil markets actually work in practice is sufficient to dismiss the worries of those who fear Chinese control of oil-producing assets or long-term contracts with producer states.15Although national security analysts have historically worried about “access,” those fears are no longer reasonable.

3. Analogies have been made between the Japanese drive for oil in the 1930s and 1940s and the present Chinese interest in international oil assets. That analogy is a poor one. The only reason that the Japanese government had to worry about access to oil was because that government went to war with every country that operated major oil production facilities.

6. M. A. Adelman represents the overwhelming consensus among economists on this point: “Rarely has a word [access] been so compact of error and confusion. Nobody has ever been denied access to oil: anyone willing to pay the current price could have more than he wanted. One may assume what he likes about future demand, supply, and market control, and conclude that the future price will be high or low, but that price will clear the market in the future as in the past. The worry about ‘access’ assumes something queer indeed: that all of the producing countries will join in refusing to sell to some particular buyer–for what strange motive is never discussed … it takes only one other country, with a desire for gain, to cure this irrationality.” M. A. Adelman, The World Petroleum Market (Baltimore: JohnsHopkins University Press, 1972), p. 260.

There have actually been three attempts by Arab states to target embargoes against certain Western states: 1956 (targeted at Britain and France), 1967 (targeted against the United States, Britain, and West Germany), and 1973 (targeted against the United States and the Netherlands). All failed to reduce imports into the targeted countries. For a political and economic history of those embargo episodes, see A. F.
