Central Bank Credibility
The market's belief that a central bank will follow through on its stated inflation and policy objectives — embedded in long-term inflation expectations.
Definition
Credibility is measured indirectly via 5y5y forward breakevens (Fed), the JGB-Treasury yield differential (BoJ), and EM real yields. A credible central bank anchors long-term inflation expectations near target regardless of near-term shocks.
Lost credibility is expensive to rebuild — Volcker's 1980s rate hikes were the cost of recovering Fed credibility after the 1970s.
