Yen Surges to Seven-Month High as Dollar Faces Inflation Report

The Japanese yen has surged to a seven-month high against the US dollar, driven by expectations of faster Bank of Japan policy tightening and growing bets that Japanese investors could repatriate funds.

The main event this week is Friday's US inflation report, which could shape the Federal Reserve's decision on whether to raise interest rates later this month and influence the dollar's direction.

Lee Hardman, senior currency analyst at MUFG, said the dollar's break below 155 yen seemed to have reinforced traders' bullish views on the Japanese currency. 'So far this year, when we have seen the yen strengthen following bouts of intervention, that 155 level was where dollar/yen tended to bottom out. Breaking past that level is a bullish signal and we could see further upside for the yen,' he said.

The US inflation data will be crucial in determining whether the Federal Reserve raises interest rates later this month, with traders pricing a roughly 60% chance of a rate hike following Friday's stronger-than-expected US nonfarm payrolls report. Elias Haddad, global head of markets strategy at BBH, noted that 'A hot CPI print would all but seal a September hike and underpin a firmer US dollar. A cooler reading would strengthen the case for a hold and leave the US dollar vulnerable to a dovish Fed repricing.'
