USD/JPY slips as risk-off flows lift Yen after tariff ruling

USD/JPY retreats toward 154.70 as softer equities and Supreme Court tariff decision weigh on the Dollar

The Greenback is on the backfoot following last Friday’s decision by the US Supreme Court to rule against IEEPA tariffs imposed by the Trump administration. This prompted traders to buy riskier assets, despite uncertainty regarding US trade policies.

Consequently, the US Dollar Index (DXY), which measures the buck’s value against a basket of six currencies, is down 0.07% at 97.73.

In the data-front, Factory Orders in December fell 0.7% MoM, reversing November’s 2.7% gain, due to weaker aircraft bookings. Hawkish comments by Fed Governor Christopher Waller capped the USD/JPY decline, after falling beneath the 154.00 milestone.

Waller said that he favors further easing by the US central bank but noted that if February’s number is stronger than January, this means that the labor market is solid, and that interest rates would remain steady.

On Tuesday, the economic docket will feature the Conference Board Consumer Confidence and the ADP Employment Change 4-week average. In Japan, the economic schedule remains absent, yet investors will eye the release of the Tokyo CPI and Industrial Production in January.

USD/JPY Price Forecast: Technical outlook

In the daily chart, USD/JPY trades at 154.62. The simple moving averages continue to edge lower, with the latest reading at 156.00. Price action beneath this gauge keeps the near-term tone heavy. RSI at 47.21 (neutral) and easing from recent prints signals waning momentum. The descending trend line from 157.66 caps recoveries at 155.11. A bullish break would expose 155.87.

The rising trend line from 139.89 underpins the broader bias, offering support near 152.48. A nearer rising line from 152.10 reinforces bids into that area. RSI remains below the 50 midline, keeping momentum subdued. The simple moving average at 156.00 stays overhead and would cap recoveries on approach. A daily close above the descending cap would improve the tone, while a slip through trend-line support would expose further downside risk.
