#9月CPI来袭原油美债走势如何 ⚠️Risk warning: The following is only a macro-market analysis and does not constitute investment advice.
The U.S. September CPI data just released: up 3.7% year over year (vs. 3.6% expected); core CPI up 2.6% year over year (vs. 2.5% expected). Both came in above expectations. This is more than a modest upside surprise in a single data release—it signals that rising energy prices are beginning to spill over into core inflation, directly roiling two of the world’s key asset classes: U.S. Treasuries and crude oil.

U.S. Treasuries: “Higher for longer” pricing is gaining traction, and pressure on long-term bonds may not ease quickly

U.S. Treasuries are the anchor for global asset pricing. The 10-year yield essentially reflects the market’s view of the “average risk-free rate in the future.”
After the data came out, 2-year and 10-year Treasury yields rose rapidly. Historically, there have been two classic patterns:
1) Oil prices rise → CPI rises → rates move higher → oil prices come under pressure (a benign negative feedback loop);
2) Oil prices rise → CPI rises → inflation expectations become unanchored → rates rise alongside oil prices (a vicious positive feedback loop, also known as the “second wave of inflation” that markets fear most right now).

The market is now testing whether we are heading into the second scenario:

- If CPI is being driven only by energy components such as gasoline, while housing, services, and wages remain stable, that would be the first scenario, with manageable pressure ahead;
- If higher energy prices feed through to services and housing, keeping core inflation persistently resilient, that would be the second scenario. Treasury yields and oil prices could then both stay elevated, keeping global financial conditions tight and increasing pressure on risk assets overall.

The four key indicators to watch next (more important than any single month’s CPI)

1. Housing and transportation services components of CPI: to assess whether higher oil prices are spreading to broader inflation;
2. Comments from Fed officials: whether they remain hawkish or emphasize “waiting and watching” rather than rushing to raise rates again;
3. Whether the 10-year Treasury yield can hold above 5.2%;
4. Whether there are further developments in the Middle East and whether shipping through the Strait of Hormuz is disrupted.

In summary: September CPI is just the “first domino.” What will really determine the market’s direction in the fourth quarter is not this month’s data, but whether the coming months can show that higher energy prices are a one-off shock that has not reignited inflation more broadly.
