Elliott Management Corp.’s Paul Singer said investors should sell out of longer-term bonds, warning that even debt securities of G7 nations aren’t a safe haven.

Speaking at the CNBC Institutional Investor Delivering Alpha Conference Tuesday in New York, the hedge fund billionaire said he sees a risk that inflation may “surprise everyone’’ and “blow through targets’’ even during poor economic conditions. Singer, 72, said the world is experiencing a “very dangerous” time in global economies and financial markets.

He also reiterated his view that “absent’’ fiscal policies have been needed to bolster growth since as early as mid-2009, rather than relying solely on interest-rate tools.

Started by Singer in 1977, Elliott Management’s two funds invest across all its strategies, which include long-short hedge funds, distressed credit, arbitrage, real estate and shareholder activism. The firm recently branched out into private equity.
