      "heading": "Key findings",
      "content": "- A high government debt could constrain monetary policy if government spending—rather than taxes—is expected to adjust in future in line with debt service costs.\n- The 'constraint' operates through an altered policy transmission mechanism via changes in the IS curve.\n- The effects of the debt-constraint on monetary policy are quite different during booms and recessions.\n- Empirical estimates indicate that Canadian monetary policy might have been constrained by a high government debt-GDP ratio during the 1990s.\n  - Policy was less loose than what inflation indicators called for."

    {
      "heading": "Methodology and scope",
      "content": "- The paper derives an interest rate rule that endogenously incorporates a debt threshold beyond which the central bank’s interest rate response to expected inflation diminishes.\n- Estimation is conducted for Canada during the first decade of its inflation targeting regime of the 1990s."
    },
    {
      "heading": "Policy implications and interpretation",
      "content": "- If future fiscal adjustment is expected to occur through government spending cuts linked to debt service costs, high debt can meaningfully limit the central bank’s ability to respond to inflation pressures.\n- Monetary policy reactions to inflation should account for fiscal structure (spending vs. taxes) and the state of the business cycle, since constraints differ in booms versus recessions.\n- Historical evidence for Canada in the 1990s suggests that failure to account for debt-induced constraints may lead to a monetary stance that is tighter than inflation indicators alone would justify."
