The next two U.S. inflation reports could determine whether the Federal Reserve raises rates at its September meeting.
The August Producer Price Index is scheduled for September 10 at 8:30 a.m. ET.
The August Consumer Price Index follows on September 11 at 8:30 a.m. ET.
The FOMC meets on September 15–16.
Normally, that would already create a high-impact macro setup.
This time, the situation is even more sensitive because Brent crude has moved above $100 and the August jobs report was stronger than expected.
Market pricing has moved toward roughly a 60% probability of a September rate increase.
That means small inflation surprises can create large moves in bonds and equities.
Why Does PPI Matter?
PPI measures prices received by producers.
It provides information about cost pressure before some of those costs reach consumers.
Investors should watch both goods and services categories.
Energy matters.
Transportation matters.
Trade services matter.
If PPI accelerates, markets may worry that companies are facing higher input costs that will eventually be passed through.
PPI also contains components that can influence calculations of the Fed’s preferred PCE inflation gauge.
That makes it more important than many investors assume.
Why Does CPI Matter More?
CPI has the strongest immediate impact on market expectations.
Headline CPI includes food and energy.
Core CPI excludes those categories and provides a cleaner view of persistent underlying inflation.
Investors will focus on month-over-month changes, annual rates and category detail.
Shelter remains important.
Services remain important.
But energy now deserves special attention.
The latest oil shock occurred late enough that it may not fully appear in August CPI.
That actually makes the interpretation harder.
A soft August CPI could be followed by higher September energy inflation.
The Fed therefore has to assess both backward-looking data and a new forward-looking energy shock.
How Did the Jobs Report Change the Debate?
August payrolls increased by 162,000.
The unemployment rate remained at 4.1%.
That result reduced concern that the labor market is too weak to tolerate another hike.
The employment report did not force the Fed to tighten.
It removed one of the strongest arguments against tightening.
That shifts more weight onto inflation.
What Does $100 Oil Change?
It creates asymmetric risk.
If PPI and CPI are soft and oil falls back below $100, the Fed has a strong case for patience.
If PPI and CPI are soft but oil stays high, policymakers may still worry about future headline inflation.
If inflation data are hot and oil stays above $100, the argument for another hike becomes much stronger.
That is why this week’s inflation data may produce outsized market reactions.
Why Are Treasury Yields So Important?
The 10-year Treasury yield reached about 4.85%, its highest since November 2023.
Higher yields make mortgages more expensive.
They increase corporate borrowing costs.
They also reduce the present value of future earnings.
That is particularly important for technology and other growth stocks.
The two-year yield is more sensitive to expected Fed policy.
The 10-year reflects a broader combination of inflation, fiscal supply and long-term capital demand.
Investors should watch both.
What Would Be Bullish for Stocks?
The most market-friendly sequence would be:
soft PPI;
soft CPI;
oil easing;
two-year Treasury yields falling;
September hike odds declining.
Growth stocks would likely benefit.
Housing could benefit.
Small caps could benefit if lower rates do not come with a collapse in economic activity.
What Would Be Bearish?
The most difficult sequence would be:
hot PPI;
hot CPI;
oil holding above $100;
two-year yields moving sharply higher;
10-year yields breaking above recent highs;
markets pricing a near-certain September hike.
That would create simultaneous pressure on valuation multiples and operating margins.
What Does This Mean for Technology?
Technology now faces two separate macro and structural risks.
The first is valuation pressure from higher rates.
The second is competitive disruption from rapidly improving AI models and agents.
If inflation comes in hot, software can be hit from both directions:
lower expected pricing power;
higher discount rates.
That is why bond-market reaction is crucial.
What About Housing?
Housing remains one of the most interest-rate-sensitive parts of the economy.
Higher Treasury yields typically push mortgage rates higher.
That reduces affordability.
It can slow transactions and weaken demand for new homes.
A soft CPI print could provide relief.
A hot CPI print could extend the pressure.
What to Watch Next
September 10, 8:30 a.m. ET: August PPI.
September 11, 8:30 a.m. ET: August CPI and Real Earnings.
September 15–16: FOMC meeting.
Watch the two-year Treasury yield.
Watch the 10-year yield.
Watch Fed-funds futures.
Watch oil.
Watch the U.S. dollar.
The key question is now:
Will inflation cool enough to stop the Fed from hiking again, or will resilient employment and $100 oil make September the beginning of another tightening phase?
