Abstract

Monetary-fiscal policy tensions build-up when debt is rising and inflation is falling. The consequence is that either fiscal policy must achieve fiscal consolidation with monetary policy maintaining price stability (passive FP-active MP) or monetary policy must accommodate fiscal policy in debt stabilisation leaving fiscal policy free to achieve its spending and redistribution objectives (passive MP-active FP). We introduce the concept of a fiscal neutral rate (fiscal r-star) into a two-agent new Keynesian dynamic stochastic general equilibrium model estimated with South African data. We show two persistent gaps: (i) monetary r-star exceeds fiscal r-star, indicating a misalignment between monetary and fiscal policy; and (ii) market interest rates exceed fiscal r-star, implying that, without policy action, the risk premium on borrowing will continue to be a drag on growth and debt service costs are likely to crowd out other spending. Our model simulations show that the optimal welfare outcomes are achieved by taking steps to align fiscal r-star with monetary r-star, through introducing a credible fiscal anchor.
