All eyes are on August’s Consumer Price Index (CPI) which is expected to be released before markets open on Tuesday. Economists polled by Bloomberg had expected the headline CPI to rise 8.1% from a year earlier in August, compared with an 8.5% rise in July. On a monthly basis, the CPI is expected to fall 0.1% from July to August, mainly due to the continued easing of energy prices. If held, it would mark the first monthly decline since May 2020. The core CPI, which strips out the volatile food and energy components of the report and is closely watched by the Fed, is likely to rise in August, rising 6.1% from the same month last year, more than 5 .9% year-on-year – an annual increase seen in July. The reading will likely confirm to investors whether the Federal Reserve will raise interest rates by 0.50% or 0.75% at its policy meeting later this month.
