The strongest evidence is from the official BEA release 'Personal Income and Outlays, February 2026', which reports the personal saving rate at 4.0 percent in February. The FRED page 'Personal Saving Rate (PSAVERT) | FRED | St. Louis Fed', which sources the same BEA series, shows February 2026 at 4.0 and January 2026 at 4.5, directly confirming the claimed 0.5 percentage-point decline from the prior month. That same FRED page displays recent values including Dec 2025 at 3.9, Jan 2026 at 4.5, and Feb 2026 at 4.0; this supports the statement that 4.0 was the second-lowest reading since November 2022, with 3.9 being lower. The secondary article 'US Personal Savings Rate Drops to 4.0% in February' matches this interpretation. I could not validate the exact X post because direct fetch failed, but the underlying claim is well supported by the official data series.
