    Fed September FOMC starts with 10Y at 5.00% since 2007 — TLT duration reprices on hike risk

    Question

    Fed September FOMC starts with 10Y at 5.00% since 2007 — TLT duration reprices on hike risk

    Direct answer

    The 10Y touched 5.00% for the first time since 2007 as traders price a higher chance of a Fed hike at the two-day September FOMC, pushing duration lower through term-premium expansion. Invalidates if FOMC guidance rejects a hike path and the 10Y breaks back below 4.85%. — bearish pressure on TLT.
