In Q3 2023, the U.S. Bureau of Labor Statistics (BLS) suddenly announced that it would suspend the high-frequency collection of a number of core economic data, which stems from the strict cuts in non-essential government spending in the congressional budget. As an important reference indicator for the Federal Reserve’s monetary policy decision-making, the frequency of non-farm payroll data collection has been reduced from monthly fine tracking to quarterly sampling surveys, and the sample coverage of the Consumer Price Index (CPI) has been reduced by 30%. At the same time, under the dual pressure of the energy crisis and supply chain reconstruction, the European Central Bank has raised interest rates three times in a row beyond expectations, pushing the euro against the U.S. dollar from 1.0572 to the key resistance level of 1.1218 in three months.
