Hot core inflation locks in a Fed hike

What happened

Stocks broke a four day losing streak on Friday even though the August inflation report came in warm. The S&P 500 closed up 0.9% at 7,656.98, the Dow rose 1.0% to 52,573.29, and the Nasdaq Composite gained 1.0% to 26,333.04. All three still finished the week lower, and the 10 year Treasury yield ended just under 5%, near multi year highs.

Why it happened

Two forces pulled in opposite directions and the friendlier one won. The inflation report showed consumer prices up 0.4% in August from July and 3.4% from a year ago, both in line with what economists expected, but core inflation, which is the same price measure with food and energy stripped out because those two swing wildly from month to month, rose 0.3% instead of the forecast 0.2%. That small miss matters because the Federal Reserve treats core inflation as the cleaner signal of where prices are heading, so traders raised the odds of an interest rate increase at next week's Fed meeting to roughly 87%, up from 72% the day before. Higher rates normally push stocks down, because borrowing costs more for companies and safe bonds start to look attractive next to risky shares. What offset that was oil. West Texas Intermediate crude fell to about $100 a barrel and Brent slid to about $104.68, and since energy is an input cost for nearly every business, cheaper oil lifts expected profits across the market at the same time it eases the inflation pressure forcing the Fed's hand. Apple rose 2.5% and Alphabet 2.7%, and Oracle held gains after reporting cloud infrastructure sales of $7.4 billion as customers rented more computing power for artificial intelligence.

What it means for you

The figure that touches your life most here is not the stock index, it is the 10 year Treasury yield sitting just below 5%. Mortgage rates track that yield closely, so a 30 year mortgage stays expensive and refinancing stays a bad deal while it holds up here. The same force works in your favor on the other side, because savings accounts, certificates of deposit, and money market funds pay more when yields are high, and cash parked in a checking account earning nothing is leaving real money behind. At the pump the picture is mixed. Oil fell hard on Friday, but diesel hit a record $6.05 a gallon, and diesel is what moves freight, so groceries and delivery costs feel that before a drop in crude shows up at your local station. For a retirement account, one up day after four down days is noise. The pattern worth noticing is that the Fed now looks set to raise rates rather than cut them, which is the opposite of what most people assumed a year ago, and that usually means a longer stretch of costly borrowing and unusually decent returns on cash.
