Finance Minister Taro Aso signaled that Japan’s government won’t intervene to stem the yen’s strength without due consideration, saying the markets have already somewhat taken into account the potential impact of a vote in favor of Brexit.

“Speaking of FX intervention, we won’t do it lightly,” Aso said at a press conference in Tokyo on Tuesday. “The G-7 and G-20 have agreed that abrupt moves are not desirable and we aim for stability. We will take action in line with that agreement.”

Aso’s comments came as the yen has surged more than 5 percent versus the dollar in June as global markets await the outcome of Britain’s June 23 referendum on European Union membership. The vote and its effect on the global economy has boosted the yen’s demand as a safe-haven currency.

The finance minister said the market has already taken into account Brexit to some degree, limiting upward pressure on the yen. Aso last week voiced strong concern about one-sided, abrupt and speculative moves in the foreign exchange market. The yen traded at 104.03 per dollar as of 12:49 p.m. in Tokyo.
