Yen Slips Toward 158 as BOJ Dissent Keeps Rate-Hike Path Uncertain

The Japanese yen remained under pressure on Tuesday as traders questioned whether the Bank of Japan can tighten policy quickly enough to narrow the interest-rate gap with the United States. USD/JPY traded around 157.70 after the yen fell for a third consecutive session. The move followed last week's BOJ rate increase, which took the policy rate to 1.25%, but two dissenting policymakers argued for a more cautious approach. The policy split has become an important signal for currency markets. While the BOJ has moved away from its earlier ultra-loose stance, investors are less certain about how quickly another increase could arrive. Market pricing was showing only about a 30% probability of a move to 1.5% in October. Japanese intervention risk is another factor limiting the yen's decline. Reuters reported that Japanese authorities had checked dollar-yen rates last Friday, a step that markets often associate with heightened monitoring before possible intervention. The US side of the rate equation remains supportive of the dollar. Markets were pricing a higher probability of another Federal Reserve increase, keeping the US-Japan yield gap wide. MarketMindFX View: USD/JPY is now centered on the 158.00 area. A sustained break above it would keep attention on intervention risk, while a retreat below 157.00 would indicate renewed demand for the yen.
