Why the US Federal Reserve Raised Interest Rates in September 2026, and Why the World Is Feeling It

The US Federal Reserve raised interest rates on Wednesday, September 16, 2026, for the first time since July 2023. The Federal Open Market Committee (FOMC) voted 12-0 to lift the target range for the federal funds rate by a quarter of a percentage point, to 3.75% to 4%, according to the Fed's own statement.

What the Fed said

The Fed's statement said economic activity is expanding at a solid pace, spending has been resilient and the unemployment rate has changed little. It also said "inflation remains elevated" and that the hike "will support a timelier return to the Committee's 2 percent goal."

At his news conference, Fed Chairman Kevin Warsh said inflation had been "too high for too long," according to CNBC.

Why the Fed raised rates

CNBC's reporting gives the main reasons:

• Inflation is above target. Officials now see headline PCE inflation at 3.7% this year and core at 3.4%, each 0.1 point higher than in June. They do not expect to reach 2% until 2029.
• Energy prices from the Iran war. The Fed usually "looks through" a one-off fuel price spike. This time officials worried that long-lasting high energy prices could raise inflation expectations and spread through the economy.
• A solid economy. The committee lowered its unemployment forecast to 4.1%. A strong labour market gives room to act.
• The memory of "transitory". Policymakers in 2021 expected pandemic inflation to fade, and instead inflation reached 40-year highs. CNBC says that episode is still fresh.
• Pressure building since July, when three members voted to hike instead of hold.

What comes next

According to CNBC, 16 of 18 policymakers see another hike possible this year, and four of them see two more. Two expect the Fed to stop at one. The projections show no further increases in later years, with cuts pencilled in for 2028 and 2029. Warsh did not submit a projection.

Why it matters outside the US

US interest rates influence the whole world because the dollar is the main global currency.

• Yields and mortgages rose. CNBC says the US 10-year yield had risen about a quarter point since Warsh's August 28 speech at Jackson Hole and about a full point since February. The 30-year fixed mortgage rate reached 7.19%, up more than a point from a year earlier.
• Other central banks are under pressure. Reuters reported that Europe raised rates the week before the Fed, and that the Bank of Japan was expected to raise its policy rate to 1.25% from 1%, a 31-year high, partly because a widening US-Japan rate gap could weaken the yen and lift import costs.
• Emerging-market currencies feel it. Higher US yields and a stronger dollar pull money away from countries like India. Reuters noted that the rupee was under pressure after the Fed move, along with oil prices and foreign selling.
