FOREX-Yen swings sharply as traders remain alert to intervention risks
SPY•BOJ signals possible further tightening
"If authorities fail to convince markets of their commitment, intervention could reinforce perceptions that policymakers are running out of options, thereby accelerating rather than reversing yen depreciation," Shusuke Yamada, FX/rates strategist at Bank of America said in a note.
"The stakes are high. This may not be a time to underestimate policymakers' determination to defend the currency."
The BOJ, which hiked rates to a 31-year high last month, warned for the first time that underlying inflation could exceed its target, signalling further rate hikes from as soon as September.
BOJ Governor Kazuo Ueda said many of the board members' inflation forecasts are fairly high and they see risks skewed to the upside.
Japan's slow pace of rate hikes has been blamed for pushing the yen to 40-year lows below 163 per dollar recently, and most analysts polled by Reuters expect the BOJ to raise rates again to 1.25% by year-end.
