The S&P 500 fell 0.4% in late February 2026 as global investors rotated into defensive assets amid Middle East tensions. Gold surged past $5,250 per ounce, reaching fresh highs as Iran-related oil supply concerns and Jerusalem evacuations triggered worldwide risk aversion. U.S. healthcare stocks led sector gains with a 2% advance.
Risk assets sold off across international markets. Bitcoin dropped toward $66,000 as cryptocurrency exchanges from Tokyo to London saw heavy selling. U.S. business development companies BlackRock TCP Capital and MidCap Financial both slashed dividends, signaling credit stress in private lending markets that could ripple across global leveraged finance.
Corporate earnings highlighted sharp divergence in capital flows. OpenAI closed a $110 billion funding round, the largest in global tech history, while payment processor Block surged 20% on strong transaction volumes. Language-learning platform Duolingo plunged after weak guidance disappointed investors across North American and European trading hours.
The defensive rotation mirrored patterns seen in previous geopolitical crises. Healthcare's outperformance echoed investor behavior during the 2022 Ukraine invasion and 2020 pandemic onset, when global capital fled to stable earnings sectors. Oil prices spiked on Iran supply fears, adding inflationary pressure that central banks from the Federal Reserve to the European Central Bank have struggled to contain.
Dividend cuts at major U.S. lenders carry implications beyond American markets. Business development companies hold $150 billion in private credit exposure, much of it cross-border. Payment stress among small and mid-sized businesses suggests tightening conditions could spread to European and Asian private lending markets where similar structures exist.
Trading strategies favor defensive positioning globally. Gold's break above $5,250 indicates sustained safe-haven demand across Asian, European, and American sessions. Cryptocurrency weakness suggests risk appetite remains depressed worldwide, while healthcare's relative strength makes it a tactical overweight for international portfolios seeking volatility protection.
The gap between OpenAI's mega-round and broader market weakness shows global capital concentrating in proven winners. Block's 20% surge confirms investors worldwide are rewarding established business models with strong cash flow over speculative growth plays. Credit markets warrant monitoring as BDC cuts often precede wider deterioration in high-yield bonds across developed economies.
