The Federal Reserve's policy committee meets on Tuesday and Wednesday, with its decision due at 2pm Eastern on Wednesday. The question is whether it raises its benchmark rate from the current range of 3.50 to 3.75 percent.
A month ago that was genuinely uncertain. After Fed Chair Kevin Warsh's speech at Jackson Hole on 28 August, CME's FedWatch tool put the odds of a quarter-point increase at about 56 percent. The prediction markets Kalshi and Polymarket had it at 48 and 49 percent: a coin toss.
On Monday, futures priced it at roughly 85 percent.
What moved the odds
Two things, both last week.
First, August's consumer price report. Core prices, which strip out food and energy, rose 0.3 percent in the month against forecasts of 0.2 percent. A tenth of a point sounds small. For a central bank whose chair had just said recent progress on inflation did not prove the underlying trend had improved, it was the confirmation that tipped the decision.
Second, oil. Brent rose toward $108 on Monday after Saudi Arabia shut its East-West pipeline and the Houthis took the Bab al-Mandab. Energy is excluded from core inflation, but it does not stay excluded for long: it feeds into shipping, airfares and the price of nearly everything that has to be moved.
The Fed's preferred measure, the PCE price index, was running at 3.7 percent a year, with core at 3.3 percent. Both are far above the 2 percent target.
How fast a hike reaches a household
This is where the same decision stops being one event.
Credit cards and home equity lines. These move fastest. Their rates are typically tied to the prime rate, which banks set at three percentage points above the top of the Fed's range. A quarter-point increase on Wednesday usually shows up on variable-rate card balances within one or two billing cycles, with no notice beyond the fine print already signed.
Savings accounts. These move in the household's favour, but slowly and unevenly. Online banks that compete for deposits tend to pass increases on within weeks. Large branch banks often do not pass them on at all.
Car loans. Existing fixed-rate loans do not change. New loans get more expensive as lenders reprice, which matters most to the buyers already stretched by high vehicle prices.
Mortgages. The most misunderstood. Thirty-year mortgage rates are not set by the Fed's rate. They follow long-term Treasury yields, which respond to what markets expect inflation and the Fed to do over years, not to one meeting. A hike that the market already expects can leave mortgage rates almost unmoved on the day. A hike paired with a warning of more to come can push them up. Existing fixed-rate mortgages do not change at all.
Who actually feels it
The pattern is regressive in a way that is easy to miss. A household with savings in a high-yield account and a fixed-rate mortgage can come out slightly ahead from a rate increase. A household carrying a credit card balance, with little or no savings, pays more almost immediately and gains nothing.
That is not an argument against raising rates when inflation is running near double the target. It is a description of whose bills the decision arrives in first.
What to watch
The statement and Warsh's press conference on Wednesday, for one thing above all: whether the committee describes this increase as a single adjustment or the start of a series. Markets have priced the first move. They have not settled on a second, and it is the guidance about the second that will move mortgage rates, the thing most households care about and the one the Fed moves least directly.
The meeting dates and decision time and the target range of 3.50 to 3.75 percent are from the Federal Reserve's published schedule and as reported by Cambridge Currencies. The post-Jackson Hole odds from CME FedWatch, Kalshi and Polymarket, the account of Kevin Warsh's speech, and PCE inflation of 3.7 percent with core at 3.3 percent are as reported by Yahoo Finance. The odds of roughly 85 to 86 percent on 14 September, the August core inflation reading and Brent's rise are as reported by NBC News and Yahoo Finance on 14 September 2026. The relationship between the federal funds rate, the prime rate and variable consumer rates is general. The analysis is our own.
