US CPI data today to provide Fed rate clues: this is how markets might react

Global financial markets are awaiting the release of the latest US inflation data on Wednesday, with investors looking for fresh clues on the Federal Reserve's interest rate path after weaker-than-expected jobs data and mixed policy signals from central bank officials clouded the outlook.

The July Consumer Price Index (CPI), scheduled for release at 8:30 a.m. ET by the Bureau of Labor Statistics, is expected to show a modest increase in prices.

Economists surveyed by Dow Jones expect headline inflation to rise 0.1% month-on-month, while core inflation, which excludes volatile food and energy prices, is projected to increase 0.2%.

On an annual basis, headline inflation is forecast to ease to 3.4% from 3.5% in June, while core inflation is expected to slow to 2.5% from 2.6%.

Although both readings remain above the Fed's long-term 2% inflation target, another month of subdued price growth could strengthen the case for policymakers to keep interest rates unchanged, boosting markets.

Inflation report comes after weak jobs data

The inflation figures follow a disappointing US payrolls report released last week, which showed the labour market unexpectedly shed jobs in July.

The weaker employment data prompted investors to reassess the likelihood of another rate increase this year, shifting attention to inflation as the next major indicator that could influence monetary policy.

The Federal Reserve left interest rates unchanged at its July meeting, although three of the 12 policymakers voted in favour of a rate hike.

Since then, market expectations have become more fluid as investors weigh signs of moderating inflation against lingering concerns over price pressures.

Federal Reserve Chair Kevin Warsh has also faced a challenging policy backdrop since taking office in May, with slowing labour market momentum complicating the central bank's effort to balance inflation control with economic growth.

How will the CPI data impact markets?

Analysts believe the July inflation report is unlikely to show a dramatic shift, although it will be closely scrutinised for signs that price pressures continue to ease.

Vanguard economist Adam Schickling said some of June's unusually sharp declines in several categories could return to more normal levels during July.

Even so, he believes inflation continues to move in the right direction.

"Inflation has been stickier and persistent," Schickling said, adding that it is nevertheless "trending in a positive direction, moving gradually closer toward the Fed's 2% target."

Joe Brusuelas, chief economist at RSM, said a report broadly matching expectations would likely reinforce the Federal Open Market Committee's decision to remain patient.

"If we get a July CPI report anywhere near my forecast, the balance of the committee is going to look right through the supply shock, and the FOMC will remain on hold for the remainder of the year," Brusuelas said, adding that the data would provide "something of an assist" for Warsh.

Morningstar Wealth chief multi-asset strategist Dominic Pappalardo also said continued moderation in inflation could reduce the need for additional tightening.

"CPI coming down the last couple of months may be enough to prevent the Fed from hiking rates this year," he said.

However, he cautioned that a stronger-than-expected reading could trigger a sell-off in equities as investors revive expectations of tighter monetary policy.

JPMorgan's trading desk has outlined five scenarios for the S&P 500's reaction to Wednesday's July CPI report, with the most likely outcome — core inflation between 0.2% and 0.25% — projected to lift stocks by 0.25% to 0.75%. 

It added that the S&P 500 could fall 1.5% to 2.5% if core CPI rises above 0.3% month over month, while a reading below 0.15% could lift the index 1% to 2%.

"The US has dodged the proverbial bullet from the Middle East conflict in terms of seeing an inflation spike," the trading desk wrote in a note to clients.

"Now, the market will want to see evidence that core inflation remains sticky or if another period of disinflation is possible."

Markets adjust positioning

Financial markets have already begun repositioning ahead of the data release.

According to CME's FedWatch tool, traders now see roughly an even chance of a rate increase at the Fed's September meeting after last week's payrolls report sharply reduced expectations for an immediate move.

Investors currently view October or December as more likely windows for any further tightening if inflation remains elevated.

The US dollar edged 0.1% higher in Asian trading, with the dollar index rising to 99.89 as investors remained cautious.

Analysts at DBS said a weaker-than-expected inflation reading could prompt traders to reduce long dollar positions against currencies such as the euro, Japanese yen and New Zealand dollar.

Meanwhile, oil prices also moved higher, with Brent crude gaining 0.9% to $89.69 a barrel following renewed geopolitical tensions in the Middle East that raised concerns over global energy supplies.

Chicago Federal Reserve President Austan Goolsbee said that the central bank remains more concerned about inflation staying too high than about recent weakness in the labour market, highlighting the delicate balancing act policymakers face as they prepare for their next interest rate decision.
