The core idea
Fiscal dominance describes a situation in which monetary policy becomes constrained by the government's fiscal position or financing needs.
What is happening underneath
If investors believe a central bank cannot tighten sufficiently without destabilizing public finances, inflation and term premia may rise.
How investors should read it
The concept concerns the interaction between monetary credibility and debt sustainability.
The same market move can carry different information depending on which maturity, issuer and risk premium is changing. Read the question together with the underlying concepts rather than treating one price move as a universal signal.
