📉 Federal Reserve’s First Hike Since 2023 Triggers Global Risk-Off: Every Region Reprices

The Federal Reserve’s 25bp hike to 3.75–4.00%—its first since 2023—is the dominant macro event of the week. The shock propagated globally and uniformly: every regional market in today’s briefings registered negative ETF performance. Australia iShares -1.38%, Canada -0.71%, UK -0.71%, Germany -0.24% (relative outperformer: EUR/USD weakness helps DAX exporters). The 10-year Treasury breaching 5% is the signal that reprices global duration. The global rates picture is now divided. The Fed is tightening while Brazil’s Copom confirmed its fifth consecutive Selic cut to 13.75%—central bank divergence that will drive EM FX volatility. The BoE and ECB face difficult sequencing: follow the Fed and risk choking fragile growth, or hold and risk currency weakness that imports inflation. The Dow Jones fell 631 points (-1.21%)—the sharpest single-day decline since March. Three cross-regional themes define the day. First, AI infrastructure is decisively rate-insensitive: Ray Dalio buying AI stocks, the £5bn UK data centre Astor pivot, and NEXTDC vs Megaport in Australia all demonstrate that institutional capital separates AI capex from rate-sensitive tech. Second, commodity divergence: Canadian aluminum faces a tariff death spiral while Devon Energy gets a Permian upgrade—geography and tariff exposure now matter more than the commodity itself. Third, regulatory tightening across jurisdictions: Robinhood crypto charges (US), DeepMind safety warning (UK), and Casas Bahia B3 compliance (Brazil) reflect coordinated regulatory pressure globally. The smartest institutional money—Dalio, Norway GPFG—is positioning defensively while selectively buying AI-adjacent names. The bifurcation is clear: rate-sensitive sectors under pressure, AI infrastructure a multi-year capex cycle that doesn’t care about the 10-year yield.
