美国经济几乎陷入停滞，但通胀仍然过高，美联储无法轻松救援

The U.S. economy entered 2026 with far less momentum than markets had priced in a few months earlier. According to the Bureau of Economic Analysis , fourth quarter 2025 GDP growth was revised down to 0.5%, a sharp step down from the 4.4% pace recorded in the third quarter. On its own, that revision would usually support the view that the Federal Reserve is moving closer to rate cuts. The problem is that inflation has not cooled enough to give policymakers much room. New PCE data released today shows headline inflation at 2.8% year-over-year in February, with core PCE at 3.0%. Monthly gains in both measures came in at 0.4%, a pace that still points to sticky price pressure rather than a fast return to the Fed’s 2% target. That combination has become the real macro question for Bitcoin and the broader crypto market. Investors are dealing with an economy losing steam, while inflation remains firm enough to keep the Fed cautious. The gap between the two trends has begun to shape the risk environment. It shapes the path of Treasury yields, the pricing of future rate cuts, and the willingness of investors to keep allocating into risk assets. Bitcoin has already shown that it can attract capital amid difficult macro conditions, especially when exchange-traded fund demand remains firm, and supply remains structurally constrained. Even so, weaker growth does not automatically produce an easier backdrop for crypto. The transmission channel runs through yields, liquidity, and confidence in the policy path.
