Top bond-fund managers at JPMorgan and Pimco warn financial markets are dangerously underestimating economic risks from the US war in Iran. The managers argue that investors are failing to price in the potential for a sharp economic slowdown, even as the economy already shows signs of sputtering. This assessment comes from some of Wall Street's most influential fixed-income investors.

Their warning suggests that current market valuations may not fully reflect geopolitical risks, particularly the economic fallout from military conflict in the Middle East. The managers point to the dual challenge of an already weakening domestic economy facing additional strain from international tensions. This perspective contrasts with more optimistic market sentiment that has prevailed despite ongoing geopolitical uncertainties.

The bond-fund managers' assessment carries significant weight given their firms' massive fixed-income portfolios and market influence. Their warning signals potential volatility ahead if markets adjust to properly price in these risks. For investors, this suggests reassessing portfolio allocations and considering increased exposure to defensive assets as geopolitical tensions escalate.
