Central banks’ resolve will be tested if policy-rate hikes lead to shocks

 in the bond, credit, and stock markets. With such a massive build-up of private and public debt, markets may not be able to digest higher borrowing costs. 

If there is a tantrum, central banks would find themselves in a debt trap and probably would reverse course. That would make an upward shift in inflation expectations likely, with inflation becoming endemic.
