[Federal Reserve Beige Book: Economic Activity Remains Flat, Consumer Spending Divergence Intensifies] The Federal Reserve's Beige Book indicates that U.S. economic activity has remained largely unchanged in recent weeks, with overall consumer spending declining further except among high-end consumer groups. The report notes a slight weakening in the U.S. labor market and moderate price increases. Some surveyed businesses warned of potential economic slowdown risks in the coming months, while the manufacturing sector displayed cautious optimism. Due to the interruption of key economic data collection during the U.S. government shutdown lasting until November 12, Federal Reserve officials will not have access to complete labor market and inflation data for October to November ahead of the December policy meeting.
