Milton Friedman on trade deficits

Milton Friedman, the Nobel Prize-winning economist and father of Monetarism, argued that many of the fears of trade deficits are unfair criticisms in an attempt to push macroeconomic policies favorable to exporting industries. He stated that these deficits are not harmful to the country as the currency always comes back to the country of origin in some form or another (country A sells to country B, country B sells to country C who buys from country A, but the trade deficit only includes A and B). In fact, in his view, the "worst case scenario" of the currency never returning to the country of origin was actually the best possible outcome: the country actually purchased its goods by exchanging them for pieces of cheaply-made paper. As Friedman put it, this would be the same result as if the exporting country burned the dollars it earned, never returning it to market circulation.

Critics claim that Friedman's argument is equivalent to saying that it doesn't matter if you get indebted, because eventually you will have to pay the money back. The obvious counterargument is that once a significant debt has been accumulated, paying it back may be painful. Friedman's supporters retort that when the money returns, the demand for foreign currency will make the exchange rate better for trade deficit country.

Friedman's view is seen by many as ignoring the intergenerational or long run consequences of deficits, low savings, and borrowing to fund consumption. If country A has a trade deficit because of large imports of consumer goods, other countries accumulate cash from country A. That money can be used to purchase existing investment assets and government bonds within country A. As a result, the return from those assets will accrue not to citizens of country A but to foreigners. The consumption standard of future generations in country A may therefore potentially decline as a result of the deficit. In particular, Americans are increasingly paying taxes to finance the interest on federal bonds held by foreigners. However, a criticism of this argument notes that all transactions are win-win. In the case of foreign investment in American assets, it helps fuel American economic growth and keeps US interest rates low. This argument is more appealing in the case of foreign direct investment, and less obvious when foreigners simply purchase the existing stock of assets.

Friedman also believed that deficits would be corrected by free markets as floating currency rates rise or fall with time to encourage or discourage imports in favor of the exports, reversing again in favor of imports as the currency gains strength. A potential difficulty however is that currency markets in the real world are far from completely free, with government and central banks being major players, and this is unlikely to change within the foreseeable future.

Friedman and other economists have also pointed out that a large trade deficit (importation of goods) signals that the country's currency is strong and desirable. To Friedman, a trade deficit simply meant that consumers had opportunity to purchase and enjoy more goods at lower prices; conversely, a trade surplus implied that a country was exporting goods its own citizens did not get to consume or enjoy, while paying high prices for the goods they actually received.

Perhaps most significantly, Friedman contended strongly that the current structure of the balance of payments is misleading. In an interview with Charlie Rose, he stated that "on the books" the US is a net borrower of funds, using those funds to pay for goods and services. He pointed to the income receipts and payments showing that the US pays almost the same amount as it receives: thus, U.S. citizens are paying lower prices than foreigners for capital assets to exchange roughly the same amount of income. The reasons why the U.S. (and UK) appear to earn a higher rate of return on their foreign assets than they pay on their foreign liabilities are not clearly understood. An important contributing factor is that the U.S. has investment primarily in stocks abroad, while foreigners have invested heavily in debt instruments, such as U.S. government bonds More recently, U.S. net foreign income has deteriorated, and appears set to stay in deficit in the future

Friedman presented his analysis of the balance of trade in Free to Choose, widely considered his most significant popular work.
