Wednesday (September 9th) currency trading saw the yen gain ground against both euros and the dollar amid political developments in Japan, reports MarketWatch.From its late Tuesday position against the Japanese currency, the euro fell by a marginal proportion of 0.2 per cent, taking it to 131.72 yen.This was despite the European currency strengthening its position against the dollar from $1.4223 to $1.4274.Overall, the dollar also lost ground to yen, from 92.96 towards the end of Tuesday to 92.21 on Wednesday.MarketWatch suggests that Sunday's victory of the Democratic Party in Japan could be a driving force behind the currency's rising fortunes.The news provider previously reported the election results as "a new era" for the country.However, it also noted that the economic recovery currently faced by Japan - as with many other countries of the world - is an issue with which the new administration must contend.
