Yen Trades Near 158/USD Amid Policy and Intervention Caution

Key Moments

Dollar-Yen Holds to Familiar Band Ahead of Fed and BoJ Decisions

The USD/JPY pair reversed an early dip in Asian trading on Monday, recovering to trade above the 158.00 level in the most recent dealings. Despite the intraday rebound, the currency pair stayed locked in a well-defined range.

Market participants refrained from establishing large directional positions in advance of two key central bank events: the US Federal Reserve decision on October 28 and the Bank of Japan meeting scheduled for October 29-30. Until those outcomes are known, the substantial yield advantage of US assets over Japanese equivalents and the BoJ’s cautious policy approach continued to pressure Japanese Yen (JPY) bulls, providing underlying support for USD/JPY.

Media reports last week indicated that BoJ officials saw limited justification for an unusual back-to-back interest rate hike in the absence of clear evidence that upside inflation risks would increase sharply. At the same time, the US Dollar (USD) edged away from a two-week low set on Friday, helped in part by rising tensions in the Middle East, which also lent some support to the USD/JPY pair.

Geopolitical Risks Support USD, But Yields and Intervention Fears Cap Upside

Geopolitical developments in the energy-sensitive Strait of Hormuz added to risk concerns. In the latest development, Iran’s Islamic Revolutionary Guard Corps (IRGC) said on Sunday that an oil tanker caught fire and exploded after striking a naval mine in the Strait of Hormuz. In addition, a secretary of Iran’s Supreme National Security Council, Mohsen Rezaei, warned that Tehran has prepared a new retaliation plan for any renewed US-Israeli attack, sustaining the geopolitical risk premium.

Even so, the recent sharp pullback in US government bond yields from multi-year highs, combined with what was described as Fed Chair Kevin Warsh’s reluctance to provide guidance on future policy moves, threatened to limit any significant USD appreciation. Parallel to this, speculation that Japanese authorities could again intervene to support the JPY kept traders wary and acted as another constraint on USD/JPY upside.

BoJ Commentary Encourages Caution Among Dollar Bulls

Comments from Bank of Japan Governor Kazuo Ueda on Monday added another layer of nuance for investors. Ueda said that if the policy rate is not adjusted appropriately, market concerns about inflation risks could push long-term interest rates higher. He also noted that Japan is seeing a positive cycle of rising wages and recovering prices, while underlying inflation remains close to the 2% target. These remarks reinforced the case for caution before adopting more aggressive bullish positions in USD/JPY.

Technical Picture: Range Intact Around Key Moving Average

On the technical front, USD/JPY traded around the 100-period Simple Moving Average (SMA) on the 4-hour chart, a configuration that underscored the prevailing range-bound conditions. A sustained break above the upper boundary of the current range near the 158.75 region would strengthen the argument for further gains.

On the downside, immediate support was identified at the lower edge of the range around 157.60. A decisive move below that level would undermine the existing bullish bias and could trigger a deeper corrective phase on the four-hour timeframe.
