The Roca–Runciman Treaty was a commercial agreement signed on 1 May 1933 between Argentina and the United Kingdom signed in London by the Vice President of Argentina, Julio Argentino Roca, Jr., and the president of the British Board of Trade, Sir Walter Runciman.
As a byproduct of Black Tuesday and the Wall Street Crash of 1929, Great Britain, principal economic partner of Argentina in the 1920s and 1930s, took measures to protect the meat supply market in the Commonwealth. At the Imperial Preference negotiations in Ottawa, bowing to pressure, mainly from Australia and South Africa, Britain decided to severely curtail imports of Argentine beef. The idea was to enact monthly cuts of 5% during the first year of the agreement. The plan provoked an immediate outcry in Buenos Aires, and the government dispatched Vice-president Roca and a team of negotiators to London. On 1 May 1933, they concluded a bilateral treaty known as the Roca-Runciman Treaty. The Argentine Senate ratified this agreement by Law #11,693. The treaty lasted three years and was renewed as the Eden-Malbrán Treaty of 1936, which gave additional concessions to Britain in return for lower freight rates on wheat.
The treaty ensured beef export quotas equivalent to the levels sold in 1932 (the lowest point in the Great Depression), strengthening the commercial ties between Argentina and Britain.
The treaty had strong political repercussions in Argentina later triggering a conflict from the denunciations of National Representative Lisandro de la Torre.
