Yen: Bank of Japan Close to September Rate Hike – Commerzbank

Commerzbank analyst Volkmar Baur said the acceleration in Tokyo inflation provides a stronger case for the Bank of Japan to act at its September meeting. Market data shows that as of writing, traders' implied probability pricing for a September rate hike has reached around 84%, well above the 24% level seen at the end of July.

**Inflation Pressures and Policy Signals in Tandem**

Recent data indicates that Japan's inflation risks are intensifying. Inflation expectations among households, businesses, and economists are all near or above the 2% target. July wholesale prices rose at a three-year high year-on-year, highlighting clear corporate cost pressures. The Bank of Japan's July meeting released its clearest signal yet of an earlier rate hike, warning that accumulating price pressures could push core inflation above target. Some policy board members called for accelerating the pace of hikes to avoid falling behind the curve in fighting inflation.

**Intervention Effectiveness Questioned, Yen Pressure Persists**

Despite previous joint intervention by US and Japanese authorities, the yen's weakness has not been fundamentally reversed. USD/JPY is currently trading near 159.47, still close to the psychological 160 level. Market consensus holds that currency intervention alone is unlikely to reverse long-term trends. Former Bank of Japan policy board member Seiji Adachi noted that standing pat could trigger another round of yen selling, exacerbating inflation risks from import costs. Some analysts hold a pessimistic view on intervention effectiveness, arguing that even coordinated intervention would at best have only a temporary impact.

**Risk Assessment of Delayed Rate Hike**

Baur emphasized that the market has now almost fully priced in a rate hike, leaving the Bank of Japan "in a bind." If it delays action due to concerns over a fragile economy, the yen would face significant depreciation pressure. Some analysts also noted that once a September hike materializes, the market could further price in another hike in December, forming tightening expectations of roughly one hike per quarter. USD/JPY briefly approached the 160 level earlier, rebounded after the joint intervention, but subsequently weakened again, suggesting the market is testing the central bank's resolve.
