During March 16–20, 2026 week, US financial markets experienced heightened volatility driven by Middle East geopolitical tensions and spiking oil prices that sparked stagflation concerns. Major equity indexes declined, with the S&P 500 -1.9% and Nasdaq -2.0%, while fixed income markets faced pressure as Treasury yields rose 15 to 20bps across the curve due to inflationary concerns, while credit spreads widened broadly as risk aversion increased.
The primary catalyst was the oil disruption, which sent WTI and Brent prices almost +50% since the conflict started, fueling stagflation fears, combining stalled growth with energy-driven inflation. Federal Reserve policy expectations shifted dramatically, with markets now pricing no rate cuts in 2026 as "higher for longer" inflation risks dominated sentiment.
Meanwhile, assets like bitcoin and precious metals showed inconsistency, with gold retreating from earlier highs above $5,000 to drift lower by mid-week, while silver failed to maintain early strength and dropped alongside other commodities. The risk-off sentiments also led to strong outflows from emerging markets assets, The overall negative performance highlighted the market's struggle to find consistent hedges against the complex mix of geopolitical and inflationary pressures.
After the turbulent period, the new week begins on a more positive tone, following Trump's announcement of constructive talks with Iran and a possible ceasefire. Stock markets are 2-3% up and Treasury yields are trading down 3-4 basis points.
