Moneyball, Independent, Indispensable America: Bremmer’s Choices by Bill O’Grady of Confluence Investment Management
(Due to the Labor Day holiday, our next report will be published on September 21.)
Last week, we wrote our first formal book review as a Weekly Geopolitical Report. The book, Superpower: Three Choices for America’s Role in the World, is a recently published book by Ian Bremmer in which he discusses three models for American foreign policy. In our closing comments last week, we promised to take a deeper look at Bremmer’s three foreign policy models to examine their costs and benefits. In this report, we will analyze his three models of exercising the superpower role, Indispensable America, Independent America and Moneyball America. From this analysis, we will discuss which model is the most likely choice. As always, we will conclude with market ramifications.
This model mostly describes Charles Kindleberger’s hegemonic stability theory, which is that the world needs a single superpower to stabilize the world. We agree with Kindleberger’s theory, which states that when the world lacks a hegemon, the global economy struggles to function.1 The strongest argument for adopting the Indispensable America model is that the world needs a hegemon to provide two key global public goods. First, the hegemon builds a military that has the ability to project power anywhere in the world. This act provides global security and fosters international trade. Second, the superpower provides the reserve currency to the world and by this act becomes the global importer and consumer of last resort.
These two roles can be burdensome. The hegemon is required to spend large sums on defense, unlike other nations, and it is often called upon to provide security for nations around the world that face threats which do not directly affect the hegemon’s security. Looking at the history of American defense spending, the difference between the republic and the superpower periods are obvious.
From 1792 to 1940, outside of wars, U.S. defense spending averaged 1.2% of GDP. It clearly spiked during wars, but military spending plummeted as demobilization occurred after the wars ended. Note the difference after 1950 (shown as a vertical line on the above chart). Defense spending remained elevated during this period, averaging 6.1% of GDP from 1950 to 2014.
This level of defense spending is required of the superpower. The U.S. is the only nation on earth that can project military force anywhere. By possessing this power, it bears responsibility for keeping global sea lanes free of piracy and closure by hostile powers. A good example of this is the Strait of Hormuz in the Persian Gulf. About 20% of the world’s petroleum passes through this narrow strait daily. Without the presence of the U.S. Navy, it is highly likely that Iran would attempt to control world oil prices by interfering with shipping.
The reserve currency role is perhaps the least understood superpower issue for Americans. Global trade requires a generally acceptable currency for exchange. Imagine two small nations trying to conduct trade with each other. To avoid using the reserve currency, they would need to have mutual needs; each nation would want something the other has and both could agree on a price. That outcome is very rare. With most global trade currently conducted in dollars, every nation in the world has an incentive to run a trade surplus with the U.S. to acquire dollars that they can use as a universal currency.2 Since these acquired dollars probably won’t be spent immediately, foreign nations hold U.S. financial assets as reserves.
This process of providing the reserve currency distorts the U.S. economy in several ways. First, consumption will tend to exceed optimal levels. The U.S. is the global importer and consumer of last resort; a slowdown in U.S. consumption reduces global economic activity. Second, the U.S. will run persistent trade deficits. This will put tremendous pressure on firms that compete with imports and tend to undermine domestic wages. Third, because foreign reserves are held in financial assets of the reserve currency country, there is a need for deep, liquid and broad capital markets. This necessity tends to require an outsized financial sector. Fourth, the global demand for safe assets means that there is a premium placed on the government bonds of the reserve currency nation. Foreign buyers allow the reserve currency nation to run large fiscal deficits with lower interest rates than would occur in the absence of that demand. Although this factor can be a benefit, it tends to undermine fiscal restraint. Finally, the requirements of a large military, global security and strong consumption tend to foster the growth of government. There is no such thing as a small government superpower.
The U.S., being the global hegemon, has to balance its global obligations with the needs of the domestic economy. From 1945 to 1980, the U.S. accomplished this through a deeply regulated economy with very high marginal tax rates designed to create high-paying, low-skilled jobs. This model brought about large oligopolies and unions, and purposely curtailed the disruptive impact of entrepreneurship through high marginal tax rates. Unfortunately, this led to high inflation from 1965 to 1980. To counteract the inflation problem, the U.S. embarked on a policy of deregulation and globalization, which dramatically cut inflation but resulted in widening income differences. To maintain the consumption needed to supply the reserve currency, households increased their borrowing to unsustainable levels, which led to the 2008 financial crisis.
If the U.S. is going to maintain this model, it has to create a new policy that will provide the lower 80% of the income distribution with enough purchasing power to absorb the world’s imports without adding to debt. If we return to the policies prior to 1980, inflation will return with a vengeance within a decade or so.
Perhaps the only feasible way to achieve this model would be to provide a universal base income to all households (a Social Security for all adults) with a progressive, but relatively low, top marginal tax rate that would not curtail entrepreneurship.3 At this juncture, we see no political path to such an outcome. The populist opposition discussed two weeks ago4 tends to pine for a return to the 1945-80 economic model. Such a model would probably fail to provide the necessary global public goods required of the hegemon due to the populists’ opposition to foreign trade.
The Indispensable America model is very expensive. Americans were willing to bear the costs of the model when communism was viewed as a major threat. With the Cold War over, Americans have become less willing to accept the costs. At the same time, it is politically difficult to sway Americans to walk away from this model. Rand Paul is the only candidate with established views opposing many of the superpower roles. He is regularly criticized for his stance and is struggling in the polls. We suspect Bernie Sanders agrees with much of Paul’s foreign policy positions but Sanders’s followers are supporting him for reasons other than his foreign policy views. Simply put, policymakers haven’t been able to build a model for Indispensable America that can address the costs of the hegemon role and meet the needs of the domestic population.
