US Data "Reverses Expectations", Dollar Strongly Suppresses Yen
In the latest release of the revised U.S. second-quarter GDP figures, the annualized growth rate was significantly raised to 3.8%, far exceeding the previous estimate of 3.3%. At the same time, consumer spending showed strong performance, with an annualized growth rate increasing to 0.9%. This unexpectedly revised data quickly boosted the dollar index, pushing the dollar against the yen higher once again during the New York trading session, stabilizing above the 149 level.
The market initially focused on the cautious statements from Federal Reserve officials regarding the pace of interest rate cuts, which caused the dollar's movement to be moderate. However, the strong data changed investors' expectations, providing dual support for the dollar from both a safe haven and fundamental perspective, directly causing the yen to weaken further.
Divergence in Bank of Japan Policies Deepens
Unlike the robust resilience shown by the U.S. economy, the Bank of Japan still maintains its easing stance. Although there are calls for interest rate hikes from internal members, overall decision-making remains cautious. The uncertainty in the political landscape further magnifies market concerns about a delay in rate hikes.
With the upcoming election for the leader of the Liberal Democratic Party, if a dovish candidate wins, it could delay the Bank of Japan's normalization process. This means that even if domestic inflation or employment data improves, it will be difficult for policy to rapidly shift towards tightening. Compared to the Fed’s data-dependent logic, this passive observation stance makes the yen appear more vulnerable.
Manufacturing Data Adds Insult to Injury
Japan's economic fundamentals also fail to provide support for the yen. The latest PMI data shows the September manufacturing index dropped to 48.4, marking the largest decline in half a year. This is the 14th time in the past 15 months that it has fallen into contraction territory, indicating that industrial production is continuously under pressure. Weak manufacturing data further shakes investors' confidence in the yen.
Amidst the contradiction between safe-haven demand and a sluggish economy, funds are more inclined to choose the dollar as a value-preserving tool. This situation of "diverging trends despite both being safe-haven currencies" is becoming the market's dominant theme.
Technical Signals Indicate Trend Continuation
From a technical perspective, after the dollar against the yen broke the key level of 149.05, the market has confirmed a medium-term upward trend. If the exchange rate can steadily maintain above this level, the strong pattern of the dollar against the yen is likely to continue in the future.
Due to both the dollar and yen being safe-haven currencies, but with the current significant policy divergence between the Federal Reserve and the Bank of Japan, the market is more likely to interpret it as "dollar safe-haven plus premium," rather than "dual safe-haven currency resonance." This also provides indirect support for the dollar index's strength.
Risks Investors Should Watch
In the short term, the market will focus on speeches from Federal Reserve officials and the U.S. core PCE price index for August. If data continues to show inflation resilience, the dollar may further gain buying support. Meanwhile, the results of the Tokyo CPI will also influence market wagers on rate hikes by the Bank of Japan.
Overall, although the yen has safe-haven attributes, its role is significantly weakened in the context of a strong dollar. If the Bank of Japan is unable to clearly articulate a path out of easing for an extended period, the yen may continue to be in a passive position for some time to come.
