Anthony Scaramucci’s SkyBridge Capital was hit by heavy losses in March from a big bet on debt investments and now is considering possible steps after some of its hedge-fund managers prevented SkyBridge and other clients from withdrawing their money.

New York-based SkyBridge invests billions of dollars in hedge funds for wealthy clients. The firm lost 22.5% in March in its flagship fund, according to an investor document reviewed by The Wall Street Journal. For the year, the fund is down 21.9% through March. Some of those hedge funds have blocked SkyBridge and other investors from withdrawing money as they grapple with redemption pressures or less liquid markets.
