(Bloomberg) Liftoff may finally have arrived for yields in the world\u2019s biggest debt market. That\u2019s good news for the fast-money crowd that\u2019s rarely been more bearishly positioned on 10-year Treasury futures. Yields on all maturities have taken flight this week, with longer-dated rates leading the charge higher. That\u2019s despite recent warnings by DoubleLine Capital\u2019s Jeffrey Gundlach that a \u201cmassive increase\u201d in short positions against 10-year and 30-year Treasury markets could spur a short squeeze. The yield on the benchmark 10-year note has surged firmly above the much-watched 3 percent mark, trading steady at 3.06 percent in Asia on Thursday after the highest U.S. close in four months. The most recent moves have reversed a small part of the relentless curve flattening that\u2019s been seen this year, pushing some yield gaps to the widest levels in more than a month. <\/p>\n
