According to BlockBeats, the latest monthly index released on Thursday indicates that U.S. economic growth experienced a slight decline last month. As Americans focus on the upcoming presidential election, the Chicago Federal Reserve reported that the Chicago Fed National Activity Index fell to -0.28 in September from -0.01 in August. A reading above zero suggests that the economy is growing at an above-average rate.

Additionally, the index's three-month moving average decreased from -0.14 to -0.19, further highlighting a general trend of weakened economic activity ahead of the uncertain presidential election in early November.

Historically, during periods of economic expansion, the Chicago Fed National Activity Index's diffusion index typically remains above -0.35. Currently, this figure has risen from -0.21 in August to -0.16.
