TOKYO: Japanese Finance Minister Shunichi Suzuki said on Friday that he was “firmly” watching foreign exchange markets and sharp movements in the yen’s exchange rate were undesirable, when asked about the currency’s recent weakening.

“Currency rates should be set by the market, reflecting fundamentals,” Suzuki told reporters at his ministry, adding he will not comment on the levels of foreign exchange.

“Sharp moves are undesirable, currencies should move stably reflecting fundamentals. With that in mind, we will continue to keep firm watch on market moves.”

The latest verbal warning to the markets amid policymakers’ concerns that Japanese households were suffering as a result of the weak yen driving up import costs.

On the flip side, the yen’s depreciation has helped boost exporters’ profits, pushing up stock prices to a 33-year high.

Yen sags to 15-year low vs euro after BOJ rate decision

The yen was largely steady on Friday at 143.05 per dollar, languishing near an over seven-month low of 143.23 hit in the previous session.

The yenncy came under renewed pressure after the Bank of Japan (BOJ) maintained an ultra-dovish stance at its meeting last week.

Data out on Friday showed that Japan’s core consumer inflation topped forecasts in May and an index excluding fuel costs rose at the fastest annual pace in 42 years, putting pressure on the BOJ to phase out its massive stimulus.
