The USD/JPY currency pair is undergoing a significant shift in dynamics, with Japanese bond yields now playing a more prominent role than U.S. Treasuries in driving its movements. Recent correlation data reveals a marked increase in the pair’s sensitivity to Japanese Government Bond (JGB) yields, particularly at the longer end of the curve. This change highlights the growing importance of upcoming Japanese economic data, such as inflation and retail sales, while U.S. economic events, including the Personal Consumption Expenditures (PCE) report, consumer confidence, and GDP revisions, also remain on the radar.
USD/JPY Dips Below 151, Bears in Control
On Friday, the downside risks highlighted in the previous report materialized, with USD/JPY breaking through the 151 mark and hitting fresh lows for 2025. Momentum now favors selling rallies, with key support levels at 148.65 and 147.20. For bulls to regain control, a move back above 151 is necessary, especially after Friday’s failed attempt to push above 150. Potential wildcards include remarks from former President Donald Trump and new developments regarding the coronavirus, both of which could spark renewed demand for the yen, particularly against currencies other than the U.S. dollar.
Japanese Bond Yields: The New Driver of USD/JPY
While interest rate differentials between the U.S. and Japan have historically driven USD/JPY, recent shifts indicate that Japanese bond yields have become the more influential factor. This marks a reversal from last year, where U.S. Treasury yields played a larger role in guiding the currency pair’s movements. According to recent data, the 20-day correlation between USD/JPY and Japanese two- and ten-year bond yields stands at 0.83 and 0.81, respectively, compared to a much weaker correlation with U.S. Treasuries at -0.36 and 0.4. Notably, the relationship between USD/JPY and long-term yield differentials (two- and ten-year spreads) is particularly strong, with a correlation coefficient of 0.91, indicating a consistent alignment over the past month.
Event Risks and Volatility Outlook
Looking ahead, several key events could influence USD/JPY volatility. Traders are advised to focus on high-impact reports, such as Japanese inflation data and retail sales, which could either fuel or temper expectations of a Bank of Japan (BOJ) rate hike. On the U.S. side, the PCE report, consumer confidence, and Q4 GDP revisions are expected to remain in focus, although recent data has often aligned with consensus forecasts, limiting their potential to drive major market movements.
In addition to these reports, speeches from Federal Reserve officials and upcoming U.S. Treasury auctions could also impact the currency pair. Despite a diminished correlation with U.S. Treasury yields in recent weeks, these events are still capable of influencing sentiment. Furthermore, corporate earnings—particularly Nvidia’s results—are likely to play a role in shaping risk appetite. A weak earnings report could increase pressure on yen carry trades.
Geopolitical Risks and Wildcards
Geopolitical factors also add uncertainty to the market. U.S. President Donald Trump’s comments and concerns over a potential new coronavirus strain could generate volatility. While the full impact is difficult to gauge, heightened fears around the virus could lead to a flight to safety, benefiting the Japanese yen, especially against non-dollar currencies.
Bearish Bias Remains for USD/JPY
Downside risks have already materialized, with USD/JPY dipping below the critical 151 level, marking new 2025 lows. Technical indicators, such as the RSI (14) and MACD, continue to suggest building downside momentum. Traders are now targeting a retest of the December 2024 swing low at 148.65, with further downside potential to 147.20. The 144 level, which USD/JPY reached in September 2024, also remains a key level to watch. On the upside, the pair faces significant resistance near 151, as evidenced by Friday’s failed attempt to break above 150.
As market conditions evolve, USD/JPY’s correlation with Japanese bond yields remains a crucial factor for traders to monitor in the coming weeks.
