JPM US Market Intelligence Desk View: Asymmetric Risk, Bond Market More Sensitive to Hot Prints
The July CPI print is a key near-term macro catalyst because it will shape the market’s view of whether inflation is re-accelerating or whether another disinflation window is opening. The desk framing is that equities are cleaner, but the bond market is more vulnerable to an upside inflation surprise, which creates an asymmetric reaction function.
Feroli’s forecast:
CPI Measure | MoM Forecast | YoY Forecast |
|---|---|---|
Headline CPI | +0.12% | 3.4% |
Core CPI | +0.22% | 2.5% |
The desk’s scenario analysis focuses on core CPI MoM and 1-day S&P 500 moves.
1. JPM Market Intel CPI Scenario Matrix
Probability | Core CPI MoM Outcome | Expected 1-Day SPX Reaction |
|---|---|---|
5% | Above 0.30% | -1.5% to -2.5% |
25% | 0.25% to 0.30% | -0.50% to -1.25% |
40% | 0.20% to 0.25% | +0.25% to +0.75% |
25% | 0.15% to 0.20% | +0.50% to +1.00% |
5% | Below 0.15% | +1.00% to +2.00% |
The probability-weighted expected reaction is mildly positive but with meaningful left-tail risk.
Using midpoints:
Bucket | Probability | SPX Midpoint Reaction | Contribution |
|---|---|---|---|
Above 0.30% | 5% | -2.00% | -0.10% |
0.25%–0.30% | 25% | -0.875% | -0.219% |
0.20%–0.25% | 40% | +0.50% | +0.200% |
0.15%–0.20% | 25% | +0.75% | +0.188% |
Below 0.15% | 5% | +1.50% | +0.075% |
Approximate probability-weighted SPX move:
−0.10%−0.219%+0.200%+0.188%+0.075%=+0.144%−0.10%−0.219%+0.200%+0.188%+0.075%=+0.144%
So the desk distribution is slightly positive on average, but downside is sharper if core CPI prints hot.
2. Options Pricing
Options expiring on August 12 were pricing roughly a:
0.9% move
based on August 7 prices.
The desk notes this is slightly below recent history, where implied CPI event moves have been closer to:
1.1%
That means CPI vol is not especially rich.
In the prior close update, the S&P implied move through the next close was cited closer to 0.59%, reflecting more recent pricing / decay into the event. Either way, the key message is:
The market is pricing a relatively contained CPI move compared with prior inflation events.
3. Why the Reaction Is Asymmetric
The desk explicitly frames the bond market as more sensitive to inflation spikes.
The reason:
real yields are already high
nominal 5y5y yields have moved higher despite softer macro data
CTAs remain short Treasury futures
inflation expectations have eased, so a hot print would challenge the disinflation narrative
equity positioning is cleaner, but rates are still the key transmission channel
Thus:
Hot CPI→Yields Up→Equity Multiple PressureHot CPI→Yields Up→Equity Multiple Pressure
The hawkish print hurts more than a dovish print helps because the market is already concerned about sticky inflation and high real rates.
4. Fed September Hike Probability
The next two inflation prints are important for assessing whether the Fed hikes in September.
The market has moved away from a Middle East-driven inflation spike / recession scare, but it still needs confirmation that core inflation is not re-sticking.
The key question:
Was June’s weak core CPI the start of another disinflation period, or just a one-off downside surprise?
Feroli does not expect payback for June, but he does expect July to re-firm.
That is important:
June core CPI: -0.02% MoM
July core CPI forecast: +0.22% MoM
This is a normalization, not a payback.
5. Feroli’s Core CPI Forecast Details
Feroli expects:
headline CPI: +0.12% MoM
core CPI: +0.22% MoM
core goods: +0.1%
core services: +0.2%
The forecast is basically:
Energy is a drag, food is steady, goods re-firm modestly, and services stabilize after June’s downside surprise.
6. Headline CPI: Energy Drag
Energy is expected to decline:
total energy: -1.2% MoM
motor fuel: -2.6% MoM, seasonally adjusted
Retail gasoline is expected to stay near:
US$4.00/gallon
for the remainder of the year, though this remains sensitive to Middle East developments.
This matters because headline CPI should be contained even if core re-firms.
7. Food CPI: Stable Around 3% Annualized
Food prices have been steadily rising at roughly a:
3% annualized pace
Feroli expects July food CPI to pick up slightly:
+0.3% MoM
after:
+0.2% MoM in May
+0.2% MoM in June
Food is not the main swing factor unless there is an unexpected jump.
8. Core Goods: Modest Re-Firming
Goods prices fell in each of the last two months, the softest period since 2024.
Feroli expects a return to moderate goods inflation in July due to:
residual tariff pass-through
rising tech prices
business survey signals
select product price hikes
Core goods forecast:
+0.1% MoM
This is important because goods disinflation had helped suppress core CPI. If goods re-firm, the market may worry that the disinflation impulse is fading.
9. Apple Price Hikes Could Boost Education / Communication Goods
One notable detail is Apple’s June 25 price increases:
computers up at least 15%
tablets up at least 20%
Assumptions:
Apple has roughly 20% US PC share
Apple has roughly 50% tablet share
PCs / tablets are 80% of global PC/tablet sales value
tablets are 20%
computers / peripherals / smart home devices are 39% of education and communication goods
PCs/tablets are assumed to be 80% of that category
The estimated impact on education and communication goods is around:
+1.4%, rounded to +1.5%
This is a key upside risk within core goods.
10. Vehicles: Mostly Stable
New Vehicles
New vehicle prices are expected to remain stable.
Industry data show little movement over the past few years.
Used Vehicles
Used vehicle CPI has not fully responded to earlier Manheim wholesale price increases.
Feroli expects:
+0.2% MoM
for used vehicles.
This is a modest positive contribution, not a major swing.
11. Apparel and Household Goods: Tariff Effects Fading
Apparel prices jumped earlier in the year, likely due to tariff effects on new seasonal items.
But prices fell in June, and Feroli assumes:
no further change in July
Household furnishings and supplies have been gradually falling since February, and that is expected to continue.
Recreational goods surged in June, especially sporting goods and toys, but only a small rise is expected in July.
12. Shelter: Still Softening
Rent and OER are expected to continue softening.
Indicators from:
Zillow
ApartmentList
remain soft.
Feroli expects July rent and OER to rise at a pace similar to:
the average of 1Q and June
Shelter is still moving in the right direction for disinflation, but slowly.
13. Lodging: World Cup Effects Continue to Fade
Lodging away from home dropped sharply in June as pricing moved past the World Cup.
July should see further fading of World Cup-related pricing effects, but Feroli thinks most of the CPI adjustment has already occurred.
Smith Travel Research data showed completed-stay prices:
up 5.2% YoY for week ending July 25
down from 9.5% YoY for week ending June 27
So lodging may not be as large a drag as in June.
14. Airfares: Still Firm
Airfares were up:
27% YoY in June
driven by high fuel costs and limited seating capacity.
Jet fuel prices have come off highs, but Google Flights data suggest prices rose in July.
Feroli assumes:
public transportation +1.0%
This is one potential services upside risk.
15. Auto Insurance: No Rebound Expected
Auto insurance prices fell sharply in recent months.
Feroli does not expect a rebound because:
industry profit ratios had been high
state-approved price changes have been consistently negative this year
The uncertainty is whether cuts continue.
Base assumption:
declines may shrink, but no rebound
This helps cap services inflation.
16. Medical Care
Medical Care Goods
Medical care goods prices have been declining all year due to:
Medicare drug price negotiations under IRA
lower GLP-1 list prices
more generics
Feroli expects only a small decline in July.
Medical Care Services
Medical care services inflation has softened recently, with three soft prints in four months.
YoY inflation is now:
2.9%, the lowest in 18 months
Feroli expects some re-firming in July.
17. China PPI Watch
The desk flags China inflation as a longer-term lead indicator.
China PPI tends to precede US CPI / PPI trends, and China’s PPI just printed a:
3-month low
This is potentially disinflationary for global goods prices.
However, the US-specific tariff and tech-price effects may still create near-term upside noise.
18. CPI Market Reaction Playbook
Core CPI Above 0.30%
Probability: 5%
Expected SPX move:
-1.5% to -2.5%
Likely market behavior:
yields spike
September Fed hike odds rise
USD rallies
gold likely weakens initially
NDX underperforms
small caps sell off sharply
ES breaks 7724
vol reprices higher
This is the left-tail scenario.
Core CPI 0.25%–0.30%
Probability: 25%
Expected SPX move:
-0.50% to -1.25%
Likely behavior:
sticky inflation narrative returns
yields higher
bond market validates hawkish pricing
equities fade
small caps underperform despite cleaner positioning
ES likely fails below 7751, tests / breaks 7724
This is the most important bearish scenario because it has a meaningful 25% probability.
Core CPI 0.20%–0.25%
Probability: 40%
Expected SPX move:
+0.25% to +0.75%
Likely behavior:
print is close enough to expectations
no inflation scare
vol decays
yields stable to slightly lower
ES reclaims / holds 7751
SPX rotates toward 7800
small caps may continue to outperform
This is the base case and should be modestly risk-positive.
Core CPI 0.15%–0.20%
Probability: 25%
Expected SPX move:
+0.50% to +1.00%
Likely behavior:
disinflation narrative improves
yields decline
Treasury CTA short-covering risk increases
small caps outperform
NDX can squeeze
gold may rally
ES breaks above 7800
targets 7820 / 7845
This is the clean bullish scenario.
Core CPI Below 0.15%
Probability: 5%
Expected SPX move:
+1.00% to +2.00%
Likely behavior:
strong disinflation impulse
September hike probability falls sharply
yields drop
Treasury CTAs may cover shorts
small caps / Tech / duration outperform
gold rallies
USD weakens
ES can accelerate toward 7845 / 7893
This is the right-tail squeeze scenario.
19. ES Tactical Overlay
Prior ES range:
7800 range high
7724 range low
7751 key pivot
CPI scenarios map neatly onto those levels.
CPI Outcome | ES / SPX Implication |
|---|---|
Core >0.30% | Break below 7724, downside acceleration |
Core 0.25%–0.30% | Lose 7751, test / break 7724 |
Core 0.20%–0.25% | Hold / reclaim 7751, rotate toward 7800 |
Core 0.15%–0.20% | Break 7800, target 7820 / 7845 |
Core <0.15% | Upside squeeze toward 7845 / 7893 |
The market is still effectively range-bound until CPI forces acceptance above 7800 or below 7724.
20. Tactical Conclusions
1. Base Case Is Mildly Bullish
The highest probability bucket is 0.20%–0.25% core, with SPX expected up 25–75bps.
2. Risk Is Asymmetric to Hot Prints
Hot CPI likely hurts more than soft CPI helps because the bond market is inflation-sensitive and real yields are already high.
3. Options Are Not Rich
Event pricing around 0.9% is below recent CPI pricing around 1.1%, and more recent SPX implied move estimates are even lower.
4. IWM Gamma Looks Interesting
Small caps have higher rate beta and IWM straddles imply the lowest event move since September 2023.
5. ES Breakout Path Requires Soft / In-Line CPI
A print at or below Feroli’s +0.22% core forecast should help ES hold 7751 and attempt 7800. A softer print can unlock 7820 / 7845 / 7893.
Feroli expects July CPI to print +0.12% headline MoM and +0.22% core MoM, corresponding to 3.4% YoY headline and 2.5% YoY core. The desk scenario analysis assigns the highest probability to a 0.20%–0.25% core MoM print, which would likely produce a 25–75bp S&P rally.
The risk is asymmetric: a hot core print above 0.25% could trigger a larger negative reaction through yields and Fed hike pricing, while an in-line or soft print should support equities, small caps, and possibly duration-sensitive Tech. Options are pricing a contained move, around 0.9% based on earlier pricing, versus recent CPI-event pricing closer to 1.1%.
The tactical equity map remains simple: 7751 is the ES pivot, 7724 is support, and 7800 is the breakout trigger. A soft or in-line CPI keeps the bullish range-breakout setup alive, while a hot print risks breaking the range lower.
