USD/JPY has edged higher to approximately 154.75 in the early Asian session on Thursday. The Japanese Yen has weakened against the US Dollar due to a risk-on mood, prompted by the potential end of a US government shutdown and doubts about a Bank of Japan (BoJ) rate hike in December.
The US House of Representatives plans a vote on a funding package to end the government shutdown, aiming to restore disrupted services until January 30. If the shutdown concludes, it might support the US Dollar against the Yen in the near term, although the lack of October jobs and inflation data complicates economic assessments.
Influence Of Japan’s New Government
Japan’s new government might influence the BoJ to delay rate hikes, which could affect Yen valuation. Prime Minister Sanae Takaichi favours low interest rates to support economic recovery, focusing on inflation from wage growth rather than food prices.
Despite these concerns, Japanese authorities may intervene against further weakening of the Yen. Finance Minister Satsuki Katayama observed recent rapid currency movements, stating a high sense of urgency in monitoring foreign exchange movements. Japan’s economic factors, BoJ policies, bond yield differentials, and risk sentiment are key influences on the Yen’s performance against the US Dollar.
We are seeing the USD/JPY pair push towards 155 again, a level that brings back memories of the period before the major currency interventions of 2024. After the Bank of Japan’s historic, but small, rate hike in March of last year, the follow-through has been disappointing for yen bulls. This prolonged policy divergence continues to favor the dollar, especially as Japan’s latest core CPI hovers at just 2.2%, giving the BoJ an excuse to wait.
Risks Of Currency Intervention
The primary risk for anyone long USD/JPY is another currency intervention from the Ministry of Finance. We all remember the massive yen-buying operations in April and May of 2024, which totaled nearly ¥10 trillion and temporarily pushed the pair down from its highs above 160. Given the recent official warnings about watching “one-sided moves,” derivative traders should view strikes above 158 with extreme caution.
On the US side, concerns over a potential government shutdown and delayed data are creating uncertainty. The Federal Reserve has been holding steady for much of the past year, but with the latest US inflation figures coming in at a stubborn 3.4%, hopes for aggressive rate cuts are fading. This keeps the interest rate differential between the US and Japan substantial, providing a strong floor for the USD/JPY pair.
This environment is ideal for strategies that profit from either a sharp move or defined ranges. Buying long-dated JPY call options, or puts on the USD/JPY, can serve as a hedge against a surprise intervention or a sudden shift in BoJ policy. Conversely, with the market pricing out a BoJ hike, implied volatility may be underpriced, making long straddle positions attractive to capture a potential breakout in either direction.
