The global market landscape in early March 2026 is dominated by a sharp escalation in geopolitical risk. Conflict in Iran directly threatens the Strait of Hormuz, the world’s most critical oil chokepoint, according to a Morgan Stanley analysis.
The Strait is the passage for about one-fifth of global oil and liquefied natural gas consumption. Therefore, disruptions or even threatened closures can elevate gasoline prices, fan inflation and lead to declines in household consumption in the U.S., the firm noted.
“Markets may tolerate uncertainty for now, but prolonged uncertainty will be harder to look through,” said Monica Guerra, head of U.S. policy at Morgan Stanley Wealth Management. Global investors are retreating toward the perceived “safe-haven” of the U.S. dollar and high-quality debt to buffer against an increasingly uncertain geopolitical horizon.
While that flight to safety is clearly reflected in this month’s flow data, investors aren’t abandoning yield entirely. ETF Database shows that five bond funds, spanning short-term Treasuries, international debt, and emerging markets, absorbed more than $5.8 billion in net inflows since March 1.
Beneath the headlines of global conflict, a structural shift is occurring as investors move to “lock in” yields. BlackRock’s fixed-income outlook highlights an inflection point where Federal Reserve easing is pulling down short-term yields. This is encouraging a “steepening” out of cash.
As the “income advantage” returns to the bond market, investors are abandoning pure cash positions. They are favoring shorter maturities and international debt that offer durable income with limited duration risk, BlackRock noted.
Short-Term Treasuries Lead Flows
The iShares 0-3 Month Treasury Bond ETF (SGOV ) captured the largest share of demand, pulling in $2.27 billion through March 9, ETF Database data show. SGOV tracks a market-value weighted index of U.S. Treasuries maturing in three months or less and carries a 0.09% expense ratio.
The Vanguard Total International Bond Index Fund ETF Shares (BNDX ) ranked second with $908.38 million in flows, per ETF Database. BNDX offers broad market-like exposure to investment-grade bonds denominated in foreign currencies, hedged against currency fluctuations for U.S. investors.
Long-duration Treasuries also attracted attention. The iShares 20+ Year Treasury Bond ETF (TLT ) drew $776.20 million as some investors positioned for potential Fed rate cuts later in the year, ETF Database data show. The fund focuses on extended-duration government debt and carries a 0.15% expense ratio.
Another ultrashort Treasury fund pulled in $739.87 million, per ETF Database. The State Street SPDR Bloomberg 1-3 Month T-Bill ETF (BIL ) offers exposure to the ultrashort end of the maturity curve, focusing on zero coupon U.S. T-Bills with less than three months until maturity.
Emerging market debt found demand as well. The iShares J.P. Morgan USD Emerging Markets Bond ETF (EMB ) gathered $1.22 billion in inflows, ETF Database shows. EMB offers exposure to emerging markets debt denominated in U.S. dollars, delivering geographic diversification without bringing exchange rate fluctuations into the equation.
