The yen rose during forex trading yesterday (August 31st) after the Democratic Party of Japan secured a resounding victory over the Liberal Democratic Party in the general election on Sunday.The upward movement was said to have been spurred by safe-haven investors looking for security after a rout in Asian equities on Monday.However, MarketWatch explained that the rally was also influenced by lower trading volumes due to the closure of London markets yesterday during the bank holiday.Patrick Bennett, Asia foreign exchange and rates strategist at Societe Generale, told the newswire: "We have been anticipating some seasonal support for [the] Japanese yen in the run into the fiscal half-year at the end of September; the election win provides further support."The yen also climbed against the higher-yielding euro, while Europe's common currency also rose against the dollar during trading yesterday.However, speaking to Dow Jones, Vassili Serebriakov, a currency strategist at Wells Fargo in New York, said that the upward movement should not be viewed as a return to higher risk appetites.
