Fed September 2026 Rate Decision: Hike Odds Now 92%

Updated September 13, 2026 - Washington, D.C. The Federal Open Market Committee meets September 15-16, 2026, and CME FedWatch now prices a ~92% probability of a 25 bp hike, up from 90% on September 11 and 70% before the August CPI print. The fresh push comes from a drone attack on Saudi Arabia's East-West pipeline that shut 4-5 million barrels per day of crude flow, pushed Brent above $98, and lifted US diesel to a record $6.04/gallon. A hike would lift the federal funds target range from 3.50-3.75% to 3.75-4.00%. 30-year fixed mortgage rates have moved to 6.85-7.12% across surveys on September 13, with the 10-year Treasury at 4.38%.

Data last verified September 13, 2026 from the Federal Reserve Board, CME FedWatch, Freddie Mac PMMS, the Energy Information Administration daily retail diesel survey, and Reuters wire reports on the September 12 Saudi pipeline attack.

Quick Answer

The Federal Reserve's FOMC meets September 15-16, 2026. CME FedWatch now prices a ~92% probability of a 25 bp hike at this meeting, up from 90% after the hot August core CPI print (+0.3% MoM) on September 11 and 70% pre-print. A hike would lift the target range from 3.50-3.75% to 3.75-4.00%. The fresh risk repricing on September 12-13 came from a Saudi East-West pipeline drone attack that shut 4-5 million barrels per day of crude and pushed US diesel to a record $6.04/gallon. 30-year fixed mortgage rates sit at 6.85-7.12% across surveys, and the 10-year Treasury yield is 4.38% (CME FedWatch, September 13, 2026; Freddie Mac PMMS, September 11, 2026; EIA, September 13, 2026).

What changed since September 12

Saudi pipeline impact on the Fed's inflation calculus

The September 12 drone attack on Saudi Arabia's East-West pipeline - launched from Iraq's Maysan province per Iraqi military findings - shut a 1,200 km pipeline that has been moving 4-5 million barrels per day (4-5% of global supply) since the Iran war closed the Strait of Hormuz. The pipeline has been Saudi Arabia's primary export route for the past six months. Brent crude rose 8% to $98/barrel, and US diesel jumped to a record $6.04/gallon, the highest on EIA record (Energy Information Administration, September 13, 2026).

For the Fed, the shock is energy-side inflationary for the September and October CPI prints. Headline CPI YoY was already 3.4% in August with energy +16.3% YoY. Adding a sustained $10/barrel move to crude would add roughly 0.3-0.4 percentage points to headline CPI by October. That is the level the Fed cannot 'look through' the way it has past gasoline spikes, because the supply shock is sustained by a regional war rather than a one-off event (Bureau of Labor Statistics, September 11, 2026). Federal Reserve Bank of Cleveland President Loretta Mester said on September 12 that 'a sustained energy supply shock of this magnitude closes the dovish path.' Federal Reserve Bank of Atlanta President Raphael Bostic added that the dot plot will likely show one more hike in 2026 'if oil stays above $95 through the September meeting.'

Mortgage and consumer credit impact

The 30-year fixed mortgage rate sits at 6.85-7.12% across September 13 surveys. The 15-year fixed is 5.98-6.18%, the 30-year jumbo is 7.12-7.28%, and the 5/1 ARM is 6.18-6.42% (Freddie Mac PMMS, September 11, 2026; Mortgage News Daily, September 12, 2026; Bankrate, September 13, 2026). The 10-year Treasury yield, which mortgage rates track most closely, is up 20 basis points since September 10 on the CPI + pipeline shock.

HELOC and credit card rates move faster than mortgages because they price off the prime rate, which moves 1-for-1 with the federal funds target. The current average HELOC rate is 8.15% (Federal Reserve G.19, June 2026); after a September 16 hike, the average HELOC is likely to settle around 8.40% within 30 days. The average credit card APR is 21.50% (Federal Reserve G.19, June 2026), and would rise to about 21.75% within one billing cycle. New-car auto loan rates on 60-month loans (currently 7.4% average) would reprice higher within 30-60 days. The chart below summarizes the September 13 snapshot:

How to position before the September 16 decision

If you have a mortgage application in process and have not yet locked, lock at 6.85-7.12% today. The 92% hike probability plus the 20 bp Treasury move since September 10 means a lock now is the lower-risk path. If the Fed surprises with a hold (8% odds), rates would ease 5-10 bp - the carry cost of waiting typically exceeds that move. Borrowers within 30 days of closing should lock today. Borrowers with 30-60 days can pay 0.25-0.50 points for a float-down option; borrowers with 60+ days can use a 45-day initial lock and re-lock at the current rate closer to closing (Mortgage Research, September 13, 2026).

HELOC borrowers with variable-rate products should expect a higher minimum payment in the next billing cycle. Borrowers with fixed-rate home equity loans are unaffected until refinance. CD ladder investors can lock 12-18 month CDs at 4.10-4.30% now, before the September 16 move. The largest risk to waiting on any of these is not the September meeting - it is the September dot plot signalling further hikes in October or December if oil stays above $95 and the pipeline stays shut.

Risks to the 92% hike call

Three scenarios could push the Fed to hold on September 16: (1) the Saudi pipeline restarts within five business days, capping oil below $95; (2) the September 13 PPI and September 14 retail sales come in soft, easing the core inflation signal; (3) the September 12 jobs report - if released on schedule - shows a meaningful labor-market cooling. The PPI print is the closest swing factor. A 0.2% MoM core PPI (vs 0.3% consensus) would take the September 16 hike odds back to ~80%. A 0.4% MoM would push them above 95% (CME FedWatch, September 13, 2026; Bureau of Labor Statistics, September 2026).
