USD/JPY inched higher to about 159.32 in Friday’s Asian session as the yen traded cautiously after Tokyo inflation data and a warning on potential currency-market action. Tokyo CPI excluding fresh food, watched by the Bank of Japan, rose 1.3% year on year in May, easing from 1.5% and remaining below the central bank’s 2% target for a fourth month. Japan’s finance minister, Satsuki Katayama, said authorities could intervene in the forex market to curb excessive volatility in the yen.
The US Dollar Index (DXY) was slightly firmer near 99.00, while staying close to Thursday’s low of 98.95 after earlier selling linked to reports that a US-Iran deal has been prepared pending President Donald Trump’s approval. Technically, the pair held above its 20-day EMA at 158.78, with RSI around 56, while a break lower could bring 157.94 into view; on the upside, resistance sits near an almost two-year high of 160.74.
Interest Rate Divergence and BoJ Caution Support Uptrend
We see the USD/JPY trading near 157.10 today, and the upward trend seems poised to continue. The massive interest rate difference between the US Federal Reserve and the Bank of Japan remains the primary driver of this move. This fundamental gap suggests buying dollars and selling yen is still the path of least resistance.
Recent data shows Japan’s core inflation holding at 2.2%, staying above the Bank of Japan’s 2% target for several months. Despite this, the BoJ is signaling only a very gradual pace for future interest rate hikes, which the market sees as insufficient to close the gap with US rates. This cautious stance from the central bank reinforces our view of continued Yen weakness.
Official Warnings, Dollar Strength, and Trading Strategies
We are hearing the usual warnings from Japanese officials about countering excessive currency moves, which is expected as the pair approaches the 158 level. History from 2024 shows that actual intervention happened only after the rate breached the 160 mark, suggesting they are more concerned with the speed of the move than a specific number. Therefore, we view these warnings as a soft brake, not a hard stop for the trend.
The US Dollar Index (DXY) is holding firm around 104.50, reflecting the reality that the Federal Reserve is in no rush to cut interest rates. Recent US economic data continues to show a resilient economy, pushing back expectations for any immediate policy easing. This broad-based dollar strength provides a solid foundation for the USD/JPY pair’s continued ascent.
Given this outlook, we believe buying call options on USD/JPY is a sensible strategy for the coming weeks. This allows traders to capture potential gains as the pair moves towards the psychological 160 level, a target many are watching. Using options defines our risk, which is crucial given the ever-present threat of sudden and sharp intervention from Japanese authorities.
