Federal Reserve Governor Christopher Waller says the upcoming August inflation report could play a major role in determining whether the central bank raises interest rates at its September meeting. Waller indicated that if inflation continues to show signs of cooling, he could support keeping rates unchanged. However, a stronger than expected reading could push him toward another rate increase.
The comments come as investors closely watch the Federal Reserve’s next policy decision. Inflation remains above the Fed’s 2% target, while policymakers are also monitoring the labor market, energy costs, tariffs, and economic growth.
August CPI Becomes a Key Test for the Fed
Waller said his September decision will depend heavily on the latest inflation data. The August Consumer Price Index is scheduled to arrive shortly before the Federal Reserve’s September 15 and 16 policy meeting, giving officials one of their final major inflation readings before deciding whether to change rates.
The data could therefore have an immediate impact on financial markets. A softer inflation report would strengthen the argument for leaving borrowing costs unchanged. A hotter reading could increase pressure for another rate hike.
Waller has pointed to recent improvements in underlying inflation as evidence that price pressures may be moving in the right direction. He noted that a shorter term measure of core inflation had fallen from about 4.76% earlier in the year to around 3% by July.
Fed Faces a Difficult Inflation Decision
The Federal Reserve is balancing two competing concerns. Inflation is still above its 2% goal, but officials also need to avoid keeping monetary policy unnecessarily restrictive if price pressures are easing.
The current federal funds rate is between 3.50% and 3.75%. Waller described the policy setting as only marginally restrictive, leaving room for another increase if inflation becomes more persistent.
At the same time, he does not appear committed to another hike. If August inflation confirms the recent cooling trend, Waller said he would be comfortable supporting a decision to hold rates steady.
That conditional approach highlights how dependent the September decision has become on incoming economic data.
July Inflation Provided Some Encouragement
The latest available inflation figures before the August report showed some improvement. Consumer prices rose 3.4% in July from a year earlier, down from 3.5% in June. Core CPI, which excludes food and energy, increased 2.5% year over year after rising 2.6% in June.
Those figures helped reduce expectations for an immediate rate increase. However, inflation remains well above the Fed’s 2% target, meaning policymakers cannot assume that recent progress will continue.
The August report will therefore receive intense attention from traders, economists, and policymakers. The monthly details could matter as much as the headline annual figure because officials are trying to determine whether inflation is genuinely slowing or simply moving temporarily.
Energy Prices and Tariffs Add Uncertainty
Waller also faces uncertainty from factors that could push prices higher. Elevated energy costs remain a concern, particularly because geopolitical tensions involving the United States and Iran have affected oil markets.
Higher energy prices can raise transportation and production costs across the economy. If businesses pass those costs to consumers, inflation could become harder to control.
Tariffs represent another potential source of price pressure. Waller has acknowledged the risk that trade policies could push some prices higher, although he has also indicated that not every increase necessarily represents persistent inflation.
The Fed must therefore separate temporary price movements from broader inflation trends. That makes the August CPI details especially important.
Labor Market Also Matters
Inflation is not the only factor influencing the Fed. Policymakers are also watching employment and economic activity.
Waller has described the labor market as relatively stable. Recent payroll growth has been modest, with an average monthly gain of about 60,000 jobs through July.
A weakening labor market could give policymakers more reason to avoid additional tightening. Strong employment and consumer spending, however, could allow the Fed to maintain a tighter policy if inflation remains elevated.
This creates a complicated policy picture. The economy has not shown the kind of severe weakness that would automatically demand lower rates, while inflation has not fallen enough to eliminate concerns about additional tightening.
Markets Are Watching Every Fed Signal
Financial markets have become increasingly sensitive to signals from Federal Reserve officials. Investors have been adjusting their expectations for a September rate increase as policymakers deliver different views about inflation and monetary policy.
Recent market pricing has placed significant probability on a rate increase, although those expectations can change quickly after major economic reports.
Waller’s latest comments may therefore reduce some pressure for an immediate hike if investors interpret his position as leaning toward a hold. However, that view could change if August CPI shows stronger inflation than expected.
Bond yields, stock prices, the US dollar, and borrowing costs could all react to the inflation report.
What a Rate Hike Would Mean
If August inflation comes in significantly higher than expected, the Fed could face stronger pressure to raise rates. A higher policy rate would increase borrowing costs for households and businesses while potentially putting pressure on stock valuations.
Growth stocks can be particularly sensitive to interest rate expectations because higher rates can reduce the present value investors place on future earnings.
A rate increase could also support the US dollar and place additional pressure on other currencies and emerging markets. However, the market reaction would depend on how much of the move had already been priced in.
What a Rate Hold Would Mean
A decision to keep rates unchanged would signal that policymakers believe recent inflation improvements deserve more time to develop.
That outcome could provide some relief to financial markets, particularly if investors had been expecting another increase. Lower rate expectations can support stocks and bonds while reducing pressure on interest sensitive sectors.
However, a rate hold would not necessarily mean the Fed has finished tightening. If inflation later accelerates, policymakers could still raise rates at a subsequent meeting.
Waller’s comments make this distinction clear. His position appears dependent on whether the incoming data confirms continued progress toward the Fed’s inflation goal.
September Decision Will Depend on the Data
The Federal Reserve enters September with an unusually important set of economic signals ahead. Inflation remains above target, the labor market is stable but not especially strong, and energy prices face geopolitical risks.
Waller’s comments suggest that the August CPI report could become the deciding factor for his vote. If the report shows continued improvement, he could support holding rates steady. If inflation surprises to the upside, another increase remains possible.
For investors, the message is straightforward: the September Fed decision is not locked in. Markets will continue adjusting expectations as new inflation and employment data arrive.
The August CPI report will therefore be one of the most important economic releases of the month. Its impact could extend beyond the Federal Reserve to Treasury yields, stocks, currencies, consumer borrowing costs, and expectations for monetary policy later in the year.
