Market’s missing that the Fed is now boxed in. They can’t cut with headline inflation at 4%+, but hiking into an energy spike risks a policy error that crushes a consumer already losing purchasing power. The dream of a 2026 pivot is effectively dead Yahoo Asia, and traders are now forced to price in a 43% chance of a hike . I’d read this as a ‘tax on growth’ rather than a sign of overheating.
