  "summary": "This paper estimates the strength of monetary policy transmission to bank lending and deposit rates in Namibia under a pegged exchange rate regime. Using local projections, it quantifies the pass-through of domestic and South African policy rates to aggregate banking interest rates.",
  "sections": [
    {
      "heading": "Key findings",
      "content": "- The pass-through of policy rates to aggregate banking interest rates in Namibia is primarily driven by the South African Reserve Bank policy rate.\n- Effects of domestic policy rates are weaker and less persistent.\n- Transmission is asymmetric:\n  - Lending rates adjust rapidly and completely, reflecting the prevalence of variable-rate contracts and their linkage to prime rate.\n  - Deposit rates respond more slowly and incompletely, consistent with differences in funding structures and pricing behavior across banks."

      "heading": "Implications and interpretation",
      "content": "- Namibia’s pegged exchange rate regime implies strong influence from South African monetary policy on domestic banking rates.\n- Rapid and complete adjustment of lending rates suggests borrowing costs for households and firms closely track changes in policy rates linked to prime rate mechanisms.\n- Slower and incomplete adjustment of deposit rates points to heterogeneity in bank funding structures and pricing behavior, with potential implications for bank margins and savings returns."
