Commentary

Fed officials maintained a cautious tone, with Logan advocating for further balance sheet reduction and Williams reiterating that the neutral rate remains anchored near its pre-pandemic level1. This suggests the Fed is likely to proceed with quantitative tightening, but without abrupt changes to the policy rate outlook. Fixed income markets should expect gradual liquidity withdrawal, but no immediate rate volatility.

In equities, Interactive Brokers ’ S&P 500 inclusion will drive index-related flows, with passive funds rebalancing out of Walgreens. The finalized U.S.–South Korea trade deal secures significant Korean investment in U.S. assets and energy exports, supporting U.S. LNG and industrial names34. Korean Air’s potential 100-jet order is a clear positive for Boeing and the broader U.S. aerospace sector6.

Healthcare remains in focus as the White House denied reports of an imminent mRNA COVID-19 vaccine withdrawal, but ongoing policy reviews and halted grants keep pressure on vaccine makers2. Commodities traders are watching arabica coffee, which extended its rally on U.S. tariffs and supply issues; Brazil’s legal challenge adds a potential catalyst for volatility5.

International headlines add to the risk landscape: Venezuela’s border troop deployment and U.S. naval presence could affect regional sentiment8, while Saudi Arabia’s AI ambitions—pending U.S. chip export approval—highlight ongoing demand for U.S. semiconductors7. Domestically, political developments in California’s redistricting and urban crime policy debates could impact sentiment in select sectors, but are unlikely to move broad markets near term101114.
