US GDP beats expectations at 3.4%, but rising PCE inflation complicates the Fed's next move

The US economy is growing faster than expected, but inflation is moving in the wrong direction.
New economic data released on October 29 shows third-quarter GDP expanding at an annualized rate of 3.4%, up from 2.2% in Q2 and beating economists' 3.2% forecast.
Meanwhile, the Federal Reserve's preferred inflation measures both accelerated in September:
- Q3 GDP growth: 3.4% vs. 3.2% expected
- Headline PCE inflation: 3.6% YoY vs. 3.6% expected, up from 3.4%
- Core PCE inflation: 3.1% YoY vs. 3.1% expected, up from 3.0%
The combination presents a complicated picture for monetary policy.
Strong consumer spending and business investment continue to support economic growth, providing a positive backdrop for corporate earnings.
But inflation remains well above the Fed's 2% target, making it harder to justify near-term interest rate cuts.
The data comes just one day after the Federal Reserve held its benchmark interest rate steady at 3.75%–4.00%.
For stocks and crypto, resilient growth could support risk appetite, but persistent inflation and expectations of higher interest rates could limit upside.
The bigger question is whether the US economy can maintain this momentum while inflation gradually returns to target.
Strong growth is encouraging. Strong growth combined with accelerating inflation is a much tougher challenge for the Fed.
