Plaza Accord: Definition, History, Purpose, and Its Replacement

What Is the Plaza Accord?

The Plaza Accord was a 1985 agreement among the G-5 nations—France, Germany, the United States, the United Kingdom, and Japan—to manipulate exchange rates by depreciating the U.S. dollar relative to the Japanese yen and the German Deutsche mark.

Also known as the Plaza Agreement, the intention of the Plaza Accord was to correct trade imbalances between the U.S. and Germany and the U.S. and Japan, but it only corrected the trade balance with the former.

Understanding the Plaza Accord

The Plaza Accord was signed in New York City on Sept. 22, 1985, and named after the hotel where it was signed—the Plaza Hotel.

The Plaza Accord was meant to push down the U.S. dollar, with the U.S., Japan, and Germany agreeing to implement certain policy measures to achieve this mission. The U.S. pledged to reduce its federal deficit. Japan and Germany were to boost domestic demand through policies such as implementing tax cuts. All parties agreed to directly intervene in currency markets as necessary to correct current account imbalances.

Leading up to the Plaza Accord—from the beginning of 1980 to its peak in March 1985—the U.S. dollar appreciated by over 47.9%. The strong dollar put pressure on the U.S. manufacturing industry because it made imported goods relatively cheaper. This caused many major companies such as Caterpillar and IBM to lobby Congress to step in—hence, the Plaza Accord.

Following the Plaza Accord, the U.S.dollar dropped sharply (though the initial fall in the dollar actually began months before the Accord was implemented). The Accord reduced but did not eliminate the U.S.-Japan trade deficit, although it did significantly reduce the U.S. deficit with Germany. Not all of the policy goals were met, but the overall goal of weakening the dollar to ease the U.S. trade deficit worked.

The U.S. current account balance, as a percentage of gross domestic product (GDP), stabilized between 1985 and 1987 and then rose to actually achieve a slight surplus by 1991.

Replacing the Plaza Accord

By 1987, the Plaza Accord had mostly achieved its desired effect, and the U.S. government did not desire further weakening of the dollar. A second agreement, the Louvre Accord, was signed in 1987 to stop the continuing decline of the dollar and stabilize exchange rates.

The Louvre Accord was implemented to partially reverse the policies carried out under the Plaza Accord. The U.S. and Japan kept their monetary pledges and the five nations agreed to step in if their currencies moved outside of a set range.

Japan and the Plaza Accord

The Plaza Accord solidified Japan’s presence as a major player in the international market. An unintended consequence of the Accord, however, was that it caused Japan to increase trade and investment with East Asia, making it less dependent on the U.S.

Yet a rising yen may also have contributed to recessionary pressures for Japan’s economy. The strong yen led to a major short-term shock to Japanese export-based industries. To offset the effects of this shock, the Japanese government embarked on a massive campaign of expansionary monetary and fiscal policy in a bid to boost the domestic economy.

This massive macroeconomic stimulus, in combination with other policies, created equally massive credit and asset price bubbles in Japan's financial and real estate markets through the late 1980s. When this bubble burst, Japan experienced a prolonged period of low growth and deflation, lasting through the 1990s and 2000s. Thus, the Plaza Accord helped propagate the “Lost Decade” in Japan.
