(Reuters) -U.S. stock index futures were marginally higher on Monday as investors braced for a data-packed week, with focus on U.S. consumer prices that could provide strong cues about the Federal Reserve's interest rate move in September.

Markets rounded off last week amid heightened volatility, beginning with a sharp selloff on a weaker-than-expected July jobs report that sparked recession fears, and investors unwound currency carry trade positions involving the yen.

Both the S&P 500 and the Nasdaq recouped most of their losses in the last two sessions, ending with marginal weekly losses.

Investors are likely to stay on the sidelines this week until Wednesday's U.S. consumer price index (CPI) reading, which is expected to show headline inflation in July accelerated 0.2% on a monthly basis, but remain unchanged at 3% on a year-on-year basis.

Money markets are evenly split between a 50- and a 25-basis-point (bps) cut in U.S. interest rates in September, expecting a total easing of 100 bps by the end 2024, according to CME's FedWatch Tool.

Figures for July U.S. retail sales on Thursday are likely to show marginal growth, and investors expect that any weakness in the data could reignite fears of a consumer slowdown and a potential recession.

Earnings reports from Walmart and Home Depot, due later this week, will also be crucial for clues on consumer spending in the world's largest economy.

"With improving liquidity, more reasonable tech valuations, and the potential for gradual Fed rate cuts starting in September, investors should navigate summer turbulence with a steady focus on long-term opportunities," said Seema Shah, chief global strategist, Principal Asset Management.

Fed Governor Michelle Bowman softened her usually hawkish tone ever so slightly on Saturday, noting some further "welcome" progress on inflation in the last couple of months even as she said inflation remains "uncomfortably above" the central bank's 2% goal and subject to upside risks.
