Markets Pause Near Record Highs Ahead of CPI — Is 3.4% the Pass Mark?

U.S. stocks are pausing near record highs ahead of today’s July CPI report.

The market expects headline inflation to ease to 3.4% year-on-year, with core inflation at 2.5%. But with expectations for a September rate hike now near 50-50, the details—not just the headline number—could determine whether the rally continues.

Previous Data: Numbers and Impact

* June CPI: Headline -0.4% MoM / +3.5% YoY; core 0.0% / +2.6%

Impact: Lower gasoline and shelter inflation reduced rate-hike fears and supported bonds and technology stocks.

* June PCE: Headline -0.1% MoM / +3.7% YoY; core +0.1% / +3.3%

Impact: Monthly inflation cooled, but elevated annual PCE kept the Fed cautious.

* June JOLTS: Job openings fell to 7.36 million

Impact: Softer labour demand reduced the urgency for another rate hike.

* July ADP: Private employment increased by only 44,000

Impact: Confirmed that hiring momentum was weakening.

* July Nonfarm Payrolls: -23,000, versus approximately +80,000 expected; May and June were revised down by a combined 103,000

Impact: September rate-hike expectations fell, Treasury yields declined and growth stocks rallied.

* Unemployment and wages: Unemployment fell to 4.1%, but participation declined to 61.4%; wage growth slowed to 3.2% YoY

Impact: The lower unemployment rate was partly caused by people leaving the workforce, while softer wages reduced inflation pressure.

The overall message is clear:

Inflation is cooling, but employment is weakening faster.

This explains why negative payroll growth did not derail the stock market. Investors interpreted weaker employment as reducing the need for another Fed rate hike.

Today’s CPI will test that interpretation.

What Is the Market Expecting Today?

July CPI will be released at 8:30 a.m. ET, or 8:30 p.m. Singapore time.

CPI indicator July consensus June

Headline CPI MoM +0.1% -0.4%

Headline CPI YoY +3.4% +3.5%

Core CPI MoM +0.2% 0.0%

Core CPI YoY +2.5% +2.6%

The market is therefore expecting inflation to rise modestly month-on-month but ease slightly on a year-on-year basis. Reuters

Is a September Rate Hike Coming?

The Fed held its policy rate at 3.50%–3.75% in July, although three policymakers preferred a 25-basis-point increase.

Before the weak payroll report, a September hike was viewed as more likely than not. The disappointing employment data initially lowered the probability, but renewed energy-price concerns have pushed expectations back towards an even split.

Ahead of CPI, markets are pricing approximately a 52% probability of a September hike, leaving today’s inflation report as a potential deciding factor. CME FedWatch, Barron’s

Boston Fed President Susan Collins has also said she would be open to supporting a September hike if inflation remains elevated. Reuters

What About the Strait of Hormuz?

Today’s CPI measures average prices during July, not current conditions in August.

Average U.S. gasoline prices reportedly declined from approximately $4.18 per gallon in June to $4.06 in July, meaning energy could continue to restrain headline CPI.

The latest Hormuz-related rise in Brent crude towards $90 occurred mainly in August. Therefore, today’s report:

* Should reflect July’s lower average gasoline prices

* May capture some transportation and logistics pressure

* Will not reflect the full impact of August’s oil-price surge

* Could understate the energy pressure that may appear in August CPI, released in September

This is why core CPI will matter more than headline CPI today.

A higher headline reading caused mainly by energy may be viewed as temporary. Stronger shelter and core-services inflation would be more difficult for the Fed to ignore.

CPI Scenario Map

Scenario 1: Softer Than Expected

What would qualify?

* Headline CPI: 0.0% or lower MoM

* Core CPI: +0.1% or lower MoM

* Core CPI: approximately 2.4% or lower YoY

Bonds

* September hike probability falls materially

* Two-year Treasury yield likely declines the most

* Ten-year yield also moves lower

* Treasury prices rise

The two-year yield should be particularly sensitive because it responds closely to changes in Fed policy expectations.

Equities

* Lower yields support equity valuations

* Technology and growth stocks likely lead

* Nasdaq could outperform the broader market

* Rate-sensitive sectors such as real estate may also benefit

This would be the clearest “Goldilocks” outcome: inflation is cooling, employment is weakening gradually and the Fed has less reason to tighten policy.

However, an extremely weak reading accompanied by evidence of collapsing demand could eventually shift attention from inflation to recession risk.

Scenario 2: In Line With Expectations

What would qualify?

* Headline CPI: approximately +0.1% MoM / +3.4% YoY

* Core CPI: approximately +0.2% MoM / +2.5% YoY

Bonds and equities

The initial reaction may be limited. Investors will immediately examine the components:

* Soft shelter and services: Positive for bonds and technology stocks

* Strong shelter or core services: Negative for bonds; September hike risk remains

* Headline increase driven mainly by energy: Less concerning

* Broad-based core inflation: More hawkish and potentially negative for equities

An in-line report should allow the rally to continue, but it may not eliminate the possibility of a September hike because core PCE inflation remains elevated.

Scenario 3: Hotter Than Expected

What would qualify?

* Headline CPI: +0.2% or higher MoM

* Core CPI: +0.3% or higher MoM

* Core CPI: approximately 2.6% or higher YoY

Bonds

* September hike probability rises

* Two-year Treasury yield moves higher

* Ten-year yield likely rises, although possibly less than the two-year

* Bond prices fall

* The yield curve could flatten

A 0.3% core reading would matter considerably more than a 0.2% headline reading driven only by energy.

Equities

* Higher yields compress technology valuations

* The U.S. dollar could strengthen

* High-multiple and high-beta stocks may underperform

* Stagflation concerns could return because employment is weakening while inflation remains persistent

Scenario 4: Very Hot Core Inflation

A core CPI reading of +0.4% or higher MoM, especially with stronger shelter and services inflation, would represent the most negative outcome.

It could trigger:

* A sharp increase in September hike expectations

* A significant rise in short-term Treasury yields

* Broad equity de-risking

* A stronger U.S. dollar

* Larger declines in semiconductor and memory stocks

Which Technology Stocks Are Most Sensitive?

Group Cooler CPI Hotter CPI

Big Tech: GOOGL, MSFT, AMZN, META Lower yields support valuations; strong cloud, AI and advertising earnings provide additional support Higher yields compress valuations; investors may scrutinise AI spending and future returns more closely

Semiconductors: NVDA, AMD, AVGO Lower yields support high-growth multiples and strengthen confidence in continued AI investment Higher yields may trigger faster profit-taking because valuations and expectations are already elevated

Memory: MU, SK Hynix Lower yields plus strong HBM demand provide a favourable combination Most exposed to higher yields, economic-cycle concerns and energy or logistics costs

Big Tech: GOOGL, MSFT, AMZN and META

These companies have strong cash flows and balance sheets, so they are not directly dependent on cheap financing.

However, a significant portion of their valuations depends on earnings expected many years into the future. When Treasury yields rise, those future earnings are discounted more heavily, reducing the valuation investors are willing to pay today.

* Cool CPI: Supports valuations and reinforces confidence in cloud, AI and advertising growth

* Hot CPI: Creates valuation pressure and increases scrutiny of AI capital expenditure

* Relative protection: Their strong cash generation should provide more resilience than smaller, unprofitable technology companies

MSFT and AMZN may face greater questions about when AI infrastructure spending will translate into profits, while GOOGL and META also carry exposure to the advertising and consumer cycle.

Semiconductors: NVDA, AMD and AVGO

Semiconductor stocks are likely to be more volatile because they combine:

* High valuation multiples

* Strong growth expectations

* Heavy exposure to AI capital expenditure

* Significant investor positioning

* Cool CPI: Could extend the AI rally and support further multiple expansion

* Hot CPI: Could trigger faster profit-taking, even if AI demand remains strong

NVDA and AVGO’s profitability and AI exposure provide some fundamental protection. AMD may be more sensitive to changes in growth expectations and overall risk appetite.

Memory: MU and SK Hynix

Memory is the most cyclical group.

MU and SK Hynix benefit structurally from HBM and AI-server demand, but conventional DRAM and NAND pricing still depends on global economic growth, inventories and supply discipline.

The ideal outcome is therefore:

Softer inflation without a collapse in demand.

A moderately soft CPI would lower yields while preserving confidence in AI and data-centre spending.

However, extremely weak economic data could increase recession concerns and reduce expectations for consumer-electronics, PC, smartphone and traditional server demand.

What Should Investors Watch First?

1. Core CPI MoM: The key dividing line is 0.2%

2. Shelter and core services: Persistent strength would concern the Fed

3. Headline CPI and energy: Important, but potentially temporary

4. CME September hike probability: Watch whether it moves decisively above or below 50%

5. Two-year Treasury yield: The fastest market signal of changing Fed expectations

My Take

Today’s CPI does not need to be exceptionally low for the rally to continue.

A headline reading of 0.0%–0.1% MoM and core CPI of 0.1%–0.2% would support the current narrative:

Inflation is cooling, employment is weakening and the Fed can afford to remain patient.

The main danger is a 0.3% or higher core reading, particularly if shelter and services accelerate. That would revive expectations of a September hike and create an uncomfortable combination of weaker employment, persistent inflation and higher interest rates.

For technology investors, the likely short-term sensitivity ranking is:

Memory stocks > Semiconductors > Big Tech

Strong AI, cloud and HBM demand can provide a fundamental cushion. But immediately after CPI, the direction of Treasury yields and the market-implied probability of a September hike will likely determine the first move.
