Banknotes of the Japanese yen
The banknotes of the Japanese yen are part of the physical form of Japan's currency. The issuance of the yen banknotes began in 1872, two years after the currency was introduced. Throughout its history, the denominations have ranged from 0.05 yen to 10,000 yen.
Nixon shock
The Nixon Shock has been widely considered to be a political success, but an economic mixed bag in bringing on the stagflation of the 1970s and leading to the instability of floating currencies. The dollar plunged by a third during the '70s. According to the World Trade Review's report "The Nixon Shock After Forty Years: The Import Surcharge Revisited", Douglas Irwin reports that for several months, U.S officials could not get other countries to agree to a formal revaluation of their currencies. The German mark appreciated significantly after it was allowed to float in May 1971. Further, the Nixon Shock unleashed enormous speculation against the dollar. It forced Japan's central bank to intervene significantly in the foreign exchange market to prevent the yen from increasing in value. Within two days August 16–17, 1971, Japan's central bank had to buy $1.3 billion to support the dollar and keep the yen at the old rate of 360 Yen to the dollar. Japan's foreign exchange reserves rapidly increased: $2.7 billion (30%) a week later and $4 billion the following week. Still, this large-scale intervention by Japan's central bank could not prevent the depreciation of US dollar against the yen. France also was willing to allow the dollar to depreciate against the franc, but not allow the franc to appreciate against gold (Page 14 Douglas). Even much later, in 2011, Paul Volcker expressed regret over the abandonment of Bretton Woods: "Nobody's in charge," Volcker said. "The Europeans couldn't live with the uncertainty and made their own currency and now that's in trouble."
