What did the FOMC decide and why does it matter for UK investors?

The FOMC kept rates at 3.5%-3.75% and warned oil-driven inflation could persist. A steadier policy stance supports a stronger USD, which can pressure global risk assets and unhedged UK portfolios. It also raises the bar for multiple expansion, so entries should be patient and data-driven.

Why is there a USD rally after the meeting?

A firm policy stance and inflation risks support US yields, lifting the dollar. Post-FOMC, traders leaned toward tighter financial conditions, which typically favour the USD. A stronger dollar can weigh on equities and commodities, so we watch DXY pullbacks and key FX pairs for a shift in tone.

What S&P 500 today levels are most important?

Key support sits around 6612-6641, which includes the 200-day average. A reclaim of 6715 can open a move toward 6839, the Bollinger middle band. Losing 6612 risks a deeper slide. We track momentum for confirmation since RSI is near oversold while MACD still trends down.

How should UK investors adjust positioning now?

Stay diversified, keep position sizes modest, and consider partial USD hedging. Blend US quality growth with energy and healthcare to balance oil and rate risks. Use clear levels for entries and exits, and wait for confirmation if breadth is weak. Review central bank and data calendars before trading.
