The Federal Reserve kept its key interest rate at 5.25% to 5.5%, citing "some further progress" toward its 2% inflation goal. At his press conference, Fed Chair Jerome Powell said a rate cut in September is "on the table," provided the inflation data continues to be encouraging. The comments propelled stocks to their highs of the day.

Powell says a potential September rate cut would be apolitical

Federal Chair Powell said a rate cut at the September meeting would be unrelated to the upcoming presidential election.

He said the central bank would be "absolutely" apolitical if it lowered borrowing costs at the meeting. But the Fed chief also cautioned against assuming that a cut was definitely happening.

"We never use our tools to support or oppose a political party, a politician or any political outcome," Powell said.

He also said the central bank's economic forecasts do not take into account who wins the presidency.

"We would never try to make policy decisions based on the outcome of an election that hasn't happened yet," Powell said. That would be "a line we would never cross."

Powell noted November will mark his fourth presidential election at the Fed. He also emphasized that the central bank is a nonpolitical agency.

Powell suggests 50 basis-point cut unlikely

Federal Chair Powell seemed to rule out the likelihood of a 50 basis-point rate cut from the central bank.

"I don't want to be really specific about what we're going to do, but that's not something we're thinking about right now," he said.

Powell says central bank watching 'really carefully' for sharper labor market downturn

The central bank is keeping a close eye on the labor market and staying vigilant for signs of a potentially sharp downturn, Fed Chair Powell said.

"We're watching really carefully for that," he said during Wednesday's press conference. "We're aware of that role, which … I would call it a statistical thing that has happened through history."

At this point, low unemployment and a low level of layoffs suggest a "normalizing labor market," the Fed chair noted.

Economy looks 'completely different' than a year ago, Powell says

The U.S. economy today looks starkly unlike it did a year ago, Fed Chair Powell said.

The central bank raised interest rates at its July meeting in 2023. He noted that unemployment has inched higher, while the path of inflation has come down significantly.

"It was a completely different economy," he said of a year prior.

Powell described the current economy as both "historically unusual" and a "welcome outcome for the people we serve."

"What we're thinking about all the time is: How do we keep this going?" he said.

Stocks surge as Fed’s Powell says a rate cut could be a possibility in September

Fed Chair Powell gave traders the sign they have been awaiting — a rate cut could be on the table in September, depending on the economic data.

Investors cheered the findings, sending stocks to their highs of the day. The Dow Jones Industrial Average added more than 450 points, or 1.12%, while the S&P 500 jumped as much as 2.12%. The Nasdaq Composite topped 3% at the high.

Fed will evaluate inflation and employment with closer-to-equal weight, Powell says

The Fed is able to weigh prices and the labor market more equally as inflation has cooled, Chair Powell said.

"When we were far away from our inflation mandate, we had to focus on that," Powell said. "Now, we're back to a closer-to-even focus."

On the employment front, he said indicators show the job market has gradually normalized from "overheated" conditions.

Fed rate cut could be on the table as early as September if inflation test is met, Powell says

The Federal Reserve left rates unchanged on Wednesday, but Fed Chair Powell expressed in a press conference that a September rate cut could potentially be on the table.

"The broad sense of the committee is that the economy is moving closer to the point at which it would be appropriate to reduce our policy rate," he said.

"The question will be whether the totality of the data, the evolving outlook and the balance of risks are consistent with rising confidence on inflation and maintaining a solid labor market," Powell said. "If that test is met, a reduction in our policy rate could be on the table for as soon as the next meeting in September."

Second-quarter inflation data has 'added to our confidence,' Powell says

Inflation and labor data continue to move into better balance, but the central bank will not cut rates until it has gained greater confidence that inflation is moving "sustainably" toward its 2% target, Fed Chair Powell said.

"The second-quarter inflation readings have added to our confidence and more good data would further strengthen that confidence," he said.

Fed is 'attentive' to both sides of dual mandate, Powell says

Fed Chair Powell indicated that Federal Reserve members are paying close attention to the recent rise in unemployment and potential weakness in the labor market.

"As the labor market has cooled and inflation has declined, the risks to achieving our employment and inflation goals continue to move into better balance. Indeed, we are attentive to the risks to both sides of our dual mandate," Powell said.

Markets are too sanguine about the number of rate cuts in 2025, Wells Fargo Investment Institute says

Traders would do well to keep their expectations in check when it comes to Federal Reserve rate cuts in 2025, notes Scott Wren, senior global market strategist at Wells Fargo Investment Institute.

"Interest-rate markets have had a habit of getting too optimistic when it comes to rate cuts over the past two years," he wrote in an investor note on Wednesday. "We suspect markets are overly optimistic now."

Wren's team sees two rate cuts this year and just one in 2025, pointing to consumer inflation that remains too high compared to the Fed's 2% target.

"Our projection currently calls for one rate cut next year as rental apartment inflation has its typically delayed bounce late next year," he said. "We expect the Consumer Price Index (CPI) to post a 3% gain in 2025."

Federal Reserve holds steady on rates in July, points to 'some further progress' on inflation

Central bank policymakers kept interest rates at their target range of 5.25% to 5.5%, where they have been for the past year.

The Federal Reserve indicated that inflation is getting closer to its target, but gave no clear signs that a rate cut is imminent.

"In recent months, there has been some further progress toward the Committee's 2 percent inflation objective," policymakers said in their postmeeting statement.

10-year Treasury yield dips ahead of Fed’s rate decision

Bond yields have come a long way down, even as the Federal Reserve has stood pat on interest rates.

Ahead of the Federal Reserve's July rate decision, the yield on the 10-year Treasury note slid to about 4.11%, its lowest level since March 12 when it was 4.081%. Though that is just a three basis-point decline on the day, it is a far cry from last October when the benchmark yield touched 5% — a first since 2007.

The 2-year Treasury yield also hovered around 4.36%, little changed on the day. Back in April, however, the rate on this note topped 5%, spurred by worries over labor costs.

Investors who have been holding onto these risk-free bonds have been capturing attractive income since the Federal Reserve has kept rates high. Bond yields and prices have an inverse relationship. However, as bond yields fall, investors can expect to see price appreciation from that corner of their portfolio.

What investors can expect going into the Fed’s decision

Investors are looking past the Federal Reserve's policy decision for July, instead fixing their gaze on the central bank's outlook for rate cuts.

The Fed is widely expected to keep a steady hand on interest rates at the conclusion of its meeting on Wednesday, keeping its benchmark rate at a range of 5.25% to 5.5%, where they have been for the past year.

Traders will turn toward the central bank's postmeeting statement and listen closely to Fed Chair Jerome Powell's press conference for details on whether rate cuts can start in September. Indeed, fed funds futures trading suggests a 100% likelihood that policymakers will ease on rates at that meeting.
