Thursday, September 17

The Federal Reserve raised its target range 25 basis points to 3.75–4.00%, its first increase since 2023, while signaling at least one more hike later this year. The initial reaction was unambiguously hawkish: the 10-year Treasury yield reached the 5.0% area, the dollar strengthened, and equities sold off. By Thursday, however, the move had partially reversed. The 10-year yield fell back toward 4.94–4.99%, the dollar index eased to around 100.2, and the S&P 500 rose 1.1% while the Nasdaq gained 1.7%. The sharply flatter curve suggests markets are accepting tighter front-end policy but assigning greater growth risk to the path ahead.

The policy signal was global rather than solely American. The Bank of England held rates but adopted a hawkish posture, Brazil cut its Selic by 25 basis points to 13.75%, and Hong Kong matched the Fed with a 25-basis-point hike. Expectations for a Bank of Japan increase kept the yen volatile, reinforcing the sense that the era of synchronized easy money is giving way to divergent but generally tighter policy.

Brent crude fell roughly 1–2% to just below $105 a barrel, while WTI declined about 1.1%, after Saudi Arabia outlined a path to restore roughly half of its damaged East-West pipeline capacity within days and normalize flows within six weeks. The workaround through the Strait of Hormuz, supported by US military protection, reduced the probability that the disruption would become a prolonged supply shock.

That mattered beyond energy markets. The retreat from prices above $109 helped moderate inflation fears that had amplified the post-Fed Treasury sell-off, contributing to the 10-year yield’s move back below 5%. The episode also left oil’s geopolitical risk premium tied closely to Gulf security and the availability of alternative export routes. For macro markets, the repair timetable provided a near-term relief valve even as crude remained around historically elevated levels.

Technology led Thursday’s equity rebound, with chipmakers helping drive the Nasdaq 1.7% higher and the tech sector gaining more than 2%. Lumentum rose about 9.6%, highlighting continued enthusiasm for optical and communications hardware linked to data-center and AI investment. Chinese AI shares also recovered as investors gave greater weight to improving domestic growth signals and policy support.

Bitcoin’s move above $81,000 extended the same pattern into crypto: speculative demand remained strong even as the Fed delivered a clearly tighter policy message. A private-market proxy for SpaceX rose 5.2% after the company announced plans for its 14th Starship test launch on September 22, underscoring appetite for long-duration growth narratives beyond listed technology. The rebound does not erase the rate sensitivity of these assets, but it shows that positioning and structural AI demand were, for now, strong enough to overwhelm the immediate discount-rate shock.
