THE KEY PRINT

CPI

→ decides the Fed meeting on Sep 16-17

August CPI drops tomorrow, Friday, at 08:30 ET. It is the last inflation read before the Fed sets rates. A core reading below 0.20% month-on-month is what the market needs to rule a hike out.

implied move for today's session

When the market prices in this little movement, it is almost always holding its breath ahead of a bigger data point.

That is the move options price for TODAY. Tiny: the market knows the fire is tomorrow.

IMPLIED MOVE
How much the market expects to move, read from options prices.
BINARY
An event with two opposite outcomes and a sharp jump between them.

CONTEXT

TAKE

The print that decides the cycle

This is not just another inflation print: it decides whether the Fed hikes for the first time in this stretch of the cycle.
Ronfy Analysis · Editorial

Hawkish Fed signals and a split committee keep a hike alive. CPI is what tips the scale.

HAWKISH
A tough stance: prioritizes fighting inflation even if it cools growth.
FOMC
The Fed committee that sets US interest rates.

Today's PPI move is real (0.55%). The CPI and Fed figures are typical readings for such days (*illustrative).

Options barely move today, but price in far more for tomorrow's CPI and next week's Fed.

PPI
Producer prices. Out today at 08:30 ET.
FOMC
The Fed meeting on Sep 16-17, with a rate decision.

THE TWO PRINTS

PPI vs CPI

Why the second one carries more weight

PPI (TODAY)

The early warning

  • Measures prices businesses pay, not you.
  • Leads CPI by several weeks.
  • Consensus: +0.4% month-on-month headline.

CPI (TOMORROW)

The decider

  • Measures prices you pay in real life.
  • Direct referee of the Fed meeting.
  • A core below 0.20% would avoid the hike.

PPI is the raw material of inflation; CPI is what the Fed actually watches to set rates.

HEADLINE
Top-line inflation: includes everything, food and energy too.
MONTH-ON-MONTH
Change from one month to the next (MoM), not year-over-year.

TO GRASP IT

THE BASKET

What sits inside CPI

HOUSING: 34%TRANSPORT: 16%FOOD: 13%ENERGY: 7%EVERYTHING ELSE: 30%CPI100%
HOUSINGRent + cost of shelter34%
TRANSPORTCars, fuel, insurance16%
FOODGroceries + dining out13%
ENERGYPower, gas, fuel7%
EVERYTHING ELSEHealth, leisure, education, goods30%

Approximate weights of the US basket. Housing alone is worth a third of the number.

Not every price counts the same. Housing dominates the basket, which is why the market watches it so closely.

The set of goods and services whose prices are tracked to measure inflation.
WEIGHTING
How much each category counts within the total index.
