Currency wars are all the rage these days, as countries from Japan to Switzerland try to depress their legal tenders in hopes of giving their economies a boost. For now, the dollar is holding steady, but soon that will begin to change. The strong dollar, until now only a political shibboleth, will finally become an economic reality. Unfortunately, its strength may not be shared by all Americans.
The roots of this change are in the hills and valleys of the American heartland. Less than a decade from now, the United States will be a net exporter of natural gas thanks to the adoption of newer technologies like fracking. The Energy Department predicts that exports will reach about 4 billion cubic feet per day by 2035, about the same level as today's shipments from Qatar, the world's second-biggest exporter behind Russia. By 2030, the International Energy Agency expects the United States to become a net exporter of crude oil as well. Having already become the world's biggest crude-oil producer by 2020, the nation will undoubtedly be a major force in the export market.
To buy all that oil and gas, America's new customers will need dollars -- and that will begin to push up the currency's value. It will rise further still if the oil and gas industries energize the U.S. economy enough to pull in new investment from abroad. Offsetting this trend somewhat, Americans might also buy up more assets abroad in a rush of cash similar to the petrodollars that flowed out of the Middle East in the 1970s. But overall, the demand for dollars is likely to climb sharply. The prices of gold and other commodities denominated in dollars will plummet, as dollars will have become more valuable while the intrinsic value of the commodities will not have changed.
Though these shifts will be dramatic enough, the most profound effects will be on American workers and consumers. A stronger dollar is usually fine for Americans, as long as their purchasing power keeps up with the currency. Yet this is exactly where the problem will be. The new exchange rates will make it harder for non-petroleum industries -- where many more Americans are employed -- to export their products. At the same time, the strong dollar will make imports more affordable to American consumers. Some of the money generated by oil and gas will still filter through to other industries, but those dependent on exports or competing with imports could find themselves in a dire situation.
The news for consumers is not all good, either. With more income coming into the country, local prices will creep up as well. The United States might go the way of Norway and Australia, rich countries that have become two of the world's most expensive places to visit and live, in large part because of their resource booms. The combination of higher prices for goods and services and falling wages in industries unable to compete at the new exchange rates will squeeze household budgets from both ends.
