Japan’s Nikkei falls 2% amid suspected yen intervention as Asia-Pacific markets trade mixed

Core inflation — which strips out food and energy costs, increased 0.1% monthly and 3.3% from a year ago, compared with respective forecasts for 0.2% and 3.4%.

Early Friday, the yen also suddenly strengthened against the dollar after the U.S. inflation data release, prompting analysts and traders to suspect a possible intervention from the country’s ministry of finance.

The yen traded at 158.55 against the U.S. dollar at roughly 12 a.m. Tokyo time after trading around 161.52 late Thursday.

The currency strengthened further against the greenback, currently standing at 158.23.

On Friday, Japan’s top currency diplomat Masato Kanda said that authorities will take action as needed in the foreign exchange market.

Reuters also reported that Kanda said recent yen moves were somewhat rapid, but declined to comment on whether authorities had intervened in the currency.

Japan’s Nikkei 225 plunged 1.97% on Friday, leading losses in Asia after three straight days of setting new closing highs and reaching an all-time high on Thursday. The Topix also retreated, falling 0.93%.

Australia’s S&P/ASX 200 rose 0.92%, surpassing its all-time closing high of 7,896.9 set on March 28 and just shy of its all time high.

The broad market index fell 0.88%, retreating from a record it touched earlier in the session.
