Iran Risk Brief: Maintaining Defensive Posture, Vigilance for Disparate Outcomes, Opportunities

DOWNLOAD PDF

The U.S.-Israel air strikes launched Feb. 28 against Iran has opened a fluid environment with future outcomes ranging from swift combat resolution and peaceful transition to protracted conflict and wider international involvement. In general, DoubleLine fixed income portfolios, notes Bill Campbell, portfolio manager and head of the Global Sovereign Debt team, were defensively postured ahead of the conflict and have minimal exposure to the Middle East. DoubleLine, he notes in this brief, has been positioning portfolios to avoid stretched valuations in credit. With respect to interest rate risk, DoubleLine has favored somewhat lower duration relative to fixed income benchmarks while underweighting the long end of the U.S. Treasury yield curve. The investment team, Mr. Campbell says, is closely following the conflict in the Middle East and its accompanying governmental, macroeconomic and market impacts as the firm seeks to manage the risks and locate opportunities ahead.
