#每周来晒 #8月CPI数据出炉 The overall U.S. CPI data for August was broadly in line with expectations (3.4% year-on-year), but the month-on-month increase (0.4%) hit a new high since June, while core CPI month-on-month (0.3%) rebounded above expectations, indicating that the pace of inflation cooling has slowed and stickiness remains. Combined with recently stronger employment and PPI data, the report significantly boosted expectations for a September Fed rate hike and had a clear differentiated impact on various asset prices.

I. Impact on Federal Reserve policy expectations
1. Rate hike expectations rose significantly: After the data was released, market expectations for a 25-basis-point Fed rate hike at the September FOMC meeting (September 15–16) rose sharply, with the probability of a hike briefly approaching 90%. Market expectations shifted from pricing in a “rate cut” back to pricing in a “rate hike,” reflecting the view that the Fed will find it difficult to ease monetary policy in the short term amid renewed core inflation and elevated energy prices.
2. Policy path repricing: The month-on-month acceleration in inflation shattered expectations of a rapid cooling in inflation, and expectations for “higher for longer” rates were reinforced. The ultimate policy direction will depend on the wording of next week’s FOMC statement, the dot plot, and the Chair’s remarks, but rate-cut expectations have been significantly suppressed in the short term.
II. Market impact and opportunities across asset classes
1. U.S. Treasuries (neutral to bearish): The higher-than-expected inflation drove Treasury yields sharply higher, with the 10-year Treasury yield approaching the 5% threshold. The bond market faced selling pressure, with short-term rates more sensitive to the policy rate, while longer-term rates were affected by inflation expectations and the term premium, resulting in an overall downward trend.
2. U.S. stocks (neutral to bearish, with structural divergence): High-valuation growth stocks and the AI sector face an “interest-rate stress test.” As the risk-free rate (Treasury yields) rises, the discount rates for high-valuation growth stocks increase, putting pressure on valuations, especially in sectors reliant on long-term growth expectations and carrying relatively high valuations; high-quality companies with strong earnings and stable cash flows are relatively more resilient.
3. U.S. dollar (neutral to bullish): Higher-than-expected core inflation supported the appeal of dollar assets. Coupled with rising rate hike expectations, the dollar index strengthened in the short term, and dollar assets outperformed relatively.
4. Gold (neutral to bearish, volatile in the short term): Gold is highly sensitive to real interest rates (nominal rates minus inflation expectations). Rising Treasury yields increased the opportunity cost of holding gold, creating short-term pressure on prices and causing a sharp short-term decline; however, safe-haven sentiment stemming from geopolitical risks, such as the conflict in the Middle East, provided some downside support for gold prices. The short-term tug-of-war between bulls and bears has intensified, and the market needs to wait for a direction to emerge after real rates peak or inflation expectations begin rising again.
5. Crude oil (affected by both macroeconomic and geopolitical factors): As a source of inflation, elevated crude oil prices, such as oil prices breaking above $100, were an important factor driving up CPI. Higher interest rates exert some pressure on crude oil demand from a macroeconomic perspective, but supply risks arising from geopolitical conflicts continue to support oil prices, which are broadly maintaining high-level volatility.
