Why does the CPI move markets?

The CPI measures US inflation. A hotter-than-expected print pushes the Fed to keep rates high, which weighs on stocks and risk assets; a softer print fuels hopes of a rate cut and supports the market.

What is the difference between headline and core CPI?

Headline CPI covers all consumer prices, including food and energy. Core CPI strips those two out because they swing too much, leaving the underlying trend that the central bank actually tracks.

Why would the Fed raise rates again?

A central bank raises its policy rate when inflation stays above target. Higher rates cool demand but weigh on stocks and tend to lift the dollar.

Why do US stocks trade when the bond market is closed?

On Columbus Day and Veterans Day, the US cash bond market shuts while the NYSE and Nasdaq stay open. With no fresh Treasury yields, stock volume often runs thin and rate moves show up only through Treasury futures.

US CPI week: S&P 500 sits 7 points from a record

Published on October 12, 2026

The S&P 500 closed the week at 7,811, just 7 points shy of its record. Whether it breaks through likely comes down to the US CPI report for September, due Wednesday. Long-term yields sit at their highest since 2002 and the Fed already hiked in September, so this print can either fuel the next leg up or stop the rally cold.

Wall Street knocks on the record's door

The S&P 500 rose 0.59% on Friday to 7,811.51, according to TheStreet. The Dow gained 0.83% to 51,655 and the Nasdaq added 0.64% to 27,366. The S&P 500 finished the week up about 1.2%, Yahoo Finance reported.

Tuesday's record close stands at 7,818.93, per Desk of Global Markets. S&P 500 futures are up about 0.3% this morning, according to Investing.com. Stocks trade normally today, but the bond market is shut for Columbus Day.

What traders expect from US CPI

September CPI lands Wednesday at 8:30 a.m. ET, released by the Bureau of Labor Statistics. Economists expect headline inflation to climb to 3.6% year over year from 3.4% in August, according to investingLive, with a 0.6% monthly jump. Energy is doing much of the lifting, with WTI crude hovering near $90 a barrel.

Core CPI, which strips out food and energy, is seen ticking up to 2.5% from 2.4%, TradingKey notes. That's the number the Fed watches first. Oil can push the headline higher, but as long as core stays tame, the Fed has room to wait.

Why this print carries extra weight

The Fed raised rates by a quarter point in September, to a 3.75% to 4% range. Markets lean toward a pause at the October 27-28 meeting. Wednesday's data could flip that bet.

Long-term yields raise the stakes. The 10-year Treasury yield hit 5.37% last Wednesday, a 24-year high, before ending the week near 5.24%. The higher it climbs, the more expensive stocks look.

Daniela Hathorn, senior market analyst at Capital.com, laid out the setup to TheStreet. In her view, strong earnings plus cooling inflation would be the best mix for stocks. Sticky prices and weak guidance, on the other hand, would expose how much the market leans on a handful of tech names.

Banks kick off earnings season

CPI won't be the only test. JPMorgan, Goldman Sachs, Citigroup and Wells Fargo report Tuesday. Bank of America and Morgan Stanley follow Wednesday, the same day as CPI, and TSMC reports Thursday. Banks have taken a hit from the surge in long-term yields, so their read on credit and consumers will set the tone heading into the print.

Gold caught a bid as yields eased late in the week, rising 1.5% on Friday to about $4,220 an ounce. It trades CPI directly: a hot print lifts yields and the dollar, which weighs on bullion, HDFC Sky notes.

Key levels today

S&P 500 levels come from Desk of Global Markets. Gold levels come from HDFC Sky and FXStreet.

Instrument	Level (support / resistance)	Change (Oct 9 session)	Scenario / What to watch
S&P 500 (7,811.5)	Resistance 7,818.9 (record close), then 7,844.5 (intraday record). Support 7,797.8, then 7,727.6	+0.59%	A close above 7,818.9 marks a new record. Below 7,727.6, the early October gap near 7,685-7,700 comes back into view
US 10-year yield (5.24%)	Resistance 5.37% (highest since 2002)	+1 bp	A push back toward 5.37% after CPI would pressure stocks. A clear drop below 5.24% would give equities room to run
Gold XAU/USD ($4,220)	Pivot $4,200. Support $4,067 (two-month low), then $4,000-4,050	+1.5%	Above $4,200, the rebound holds. A hot CPI could send gold back toward $4,000-4,050

Economic calendar

Wednesday, October 14, 8:30 a.m. ET (2:30 p.m. Paris): September CPI. Economists expect 3.6% year over year and 2.5% for core. If core prints at 2.6% or higher, bets on an October hike come back, yields climb and the S&P 500 could lose 7,727. At 2.4% or lower, a Fed pause becomes the base case and the record is back in reach.

Thursday, October 15, 8:30 a.m. ET (2:30 p.m. Paris): September producer prices and retail sales. Economists expect gains of 0.5% and 0.3% month over month. PPI above 0.5% would back up a hot CPI. Weak sales alongside rising prices would be the worst mix for stocks.

Thursday, October 15, 11:30 p.m. ET (Friday 5:30 a.m. Paris): Fed Chair Kevin Warsh speaks, per Newsquawk. A firm tone after hot data would lift the dollar and hit gold. A patient tone would keep buyers in charge of stocks.

The bottom line

The S&P 500 is 7 points from a record, but Wednesday's CPI holds the key. Tame core inflation opens the door to a new high, while a hot print revives the yield spike and the risk of another Fed hike.
