In 1986, with the threat of tariffs looming, Washington and Tokyo cut a deal. Japan’s government agreed to put quotas on its exports of DRAM chips, limiting the number that were sold to the U.S. By decreasing supply, the agreement drove up the price of DRAM chips everywhere outside of Japan, to the detriment of American computer producers, which were among the biggest buyers of Japan’s chips. Higher prices actually benefitted Japan’s producers, which continued to dominate the DRAM market.
