F1: Inflation in the euro area is projected to decline gradually over the next few years, from 5.4% in 2023 to 2.3% in 2024, then to 2.0% in 2025, and reaching 1.9% in 2026 [1]. F2: Economic growth in the euro area is expected to be weak in the short term due to tight financing conditions and subdued confidence. Growth is anticipated to recover as inflation falls, household income recovers, and foreign demand strengthens, with real GDP projected to increase by 0.6% in 2024, 1.5% in 2025, and 1.6% in 2026 [1]. F3: The Cleveland Fed provides daily nowcasts of inflation for two price indexes: the price index for personal consumption expenditures (PCE) and the Consumer Price Index (CPI) [2]. F4: According to the Cleveland Fed's nowcasting data, the month-over-month percent change for March 2024 is projected as 0.25% for CPI, 0.30% for Core CPI, 0.19% for PCE, and 0.22% for Core PCE [2]. F5: For the same period, the year-over-year percent change projects CPI at 3.29%, Core CPI at 3.68%, PCE at 2.47%, and Core PCE at 2.61% [2]. F6: The quarterly annualized percent change for Q1 2024 has CPI at 3.60%, Core CPI at 4.04%, PCE at 2.80%, and Core PCE at 3.14% [2]. F7: The Cleveland Fed's inflation nowcasts are produced using a model that utilizes a limited number of available data series of different frequencies. Historically, these nowcasts have often been more accurate than other common benchmarks [3]. F8: The nowcasts are updated every business day around 10:00 a.m. Eastern time and are based on available monthly, weekly, and daily data sources, including daily Brent crude spot oil prices and weekly retail gasoline prices [3]. --- SOURCES --- 1: https://www.ecb.europa.eu/pub/projections/html/index.en.html 2: https://www.clevelandfed.org/indicators-and-data/inflation-nowcasting 3: https://www.ecb.europa.eu/pub/projections/html/index.en.html ----------------- Given the information and analysis provided within the context, including the newer forecasts and insights from the Cleveland Fed's nowcasting data, we can refine the speculative forecast for the CPI-U increase for March 2024 on a seasonally adjusted basis. Specifically, the Cleveland Fed's nowcasting data for March 2024 projects a month-over-month percent change of 0.25% for CPI. This direct nowcast figure from a reputable source should be taken as the most data-driven estimate available for the speculative forecast in question. Therefore, integrating this critical piece of nowcasting information, which explicitly details the expected CPI percentage change for March 2024, provides a clear and reasoned basis for the forecast. The nowcasting methodology's historical accuracy further reinforces confidence in utilizing this figure directly for the forecast. Hence, the forecast, informed by the detailed analysis and specific nowcasting data for March 2024, leads to the conclusion: The Consumer Price Index for All Urban Consumers (CPI-U) increased 0.25 percent in March 2024 on a seasonally adjusted basis.
