JPMorgan Warns of Massive Outflows from US High-Yield Bond Market

Geopolitical Tensions Spark Sell-Off in Credit Markets

Amid rising global market volatility, JPMorgan's credit research team warns of a sharp outflow from U.S. high-yield bond funds. The bank estimates a $3.7 billion withdrawal for the week ending March 18—the largest single-week outflow in nearly 11 months—driven by escalating geopolitical tensions in the Middle East.

Six Consecutive Weeks of Capital Flight

This marks the sixth straight week of net outflows, matching the streak last seen in mid-January. Widening credit spreads and growing risk aversion have pushed investors toward safer assets, as uncertainty surrounding regional conflicts reshapes market sentiment.

Historical Parallels and Divergences

• The last comparable outflow occurred in April 2023, triggered by trade policy concerns;
• Today’s environment is more complex, with inflation persistence and global unrest compounding pressures;
• Official weekly data from LSEG Lipper is expected Thursday evening, offering confirmation of early estimates.

While corporate default rates remain low, investor caution is mounting. JPMorgan cautions that without de-escalation, the high-yield sector could face prolonged stress, potentially spilling over into broader credit markets.
