TOKYO, March 31 (Reuters) – Japanese Finance Minister Satsuki Katayama warned on Tuesday the government was ready to respond “on all fronts” against volatility in markets as speculative moves are seen in the currency market, as well as in the crude oil futures market.

“We will respond on all fronts, mindful that foreign exchange volatility affects people’s lives,” she told a press conference, while stopping short of commenting on specific currency levels.

Speaking later in parliament, Katayama repeated her comments about speculative moves increasing in the currency market, underscoring Tokyo’s alarm over the yen’s renewed slide.
