The Smithsonian Agreement, announced in December 1971, created a new dollar standard, whereby the currencies of a number of industrialized states were pegged to the US dollar. These currencies were allowed to fluctuate by 2.25% against the dollar. The Smithsonian Agreement was created when the Group of Ten (G-10) states (Belgium, Canada, France, Germany, Italy, Japan, the Netherlands, Sweden, the United Kingdom, and the United States) raised the price of gold to 38 dollars, an 8.5% increase over the previous price at which the US government had promised to redeem dollars for gold. In effect, the changing gold price devalued the dollar by 7.9%.
The Bretton Woods Conference of 1944 established an international fixed exchange rate system based on the gold standard, in which currencies were pegged to the United States dollar, itself convertible into gold at 35/ounce.Anegativebalanceofpayments,growingpublicdebtincurredbytheVietnamWarandGreatSocietyprograms,andmonetaryinflationbytheFederalReservecausedthedollartobecomeincreasinglyovervaluedinthe1960s.ThedrainonUSgoldreservesculminatedwiththeLondonGoldPoolcollapseinMarch1968.OnAugust15,1971,USPresidentRichardNixonunilaterallysuspendedtheconvertibilityofUSdollarsintogold.TheUnitedStateshaddeliberatelyofferedthisconvertibilityin1944;itwasputintopracticebytheU.S.Treasury.Thesuspensionmadethedollareffectivelyafiatcurrency.Nixon′sadministrationsubsequentlyenterednegotiationswithindustrializedalliestoreassessexchangeratesfollowingthisdevelopment.MeetinginDecember1971attheSmithsonianInstitutioninWashingtonD.C.,theGroupofTensignedtheSmithsonianAgreement.TheUSpledgedtopegthedollarat38/ounce (instead of $35/ounce; in other words: the USD rate lost 7.9%) with 2.25% trading bands, and other countries agreed to appreciate their currencies versus the dollar: Yen +16.9%; Deutsche Mark +13.6%, French Franc +8.6%, British pound the same, Italian lira +7.
