3 Motivation 1. Small, open and commodity exporting economies are subject to large, sudden and (very!) persistent commodity price swings Hamann (Colombia) Monetary & Macro-pru policies CBRT-BIS-IMF / 14
4 Motivation 1. Small, open and commodity exporting economies are subject to large, sudden and (very!) persistent commodity price swings 2. Booms: credit expands, demand for both tradable (T) and nontradable (NT) goods, RER appreciates, shifts resources from the T sector to the NT Hamann (Colombia) Monetary & Macro-pru policies CBRT-BIS-IMF / 14
5 Motivation 1. Small, open and commodity exporting economies are subject to large, sudden and (very!) persistent commodity price swings 2. Booms: credit expands, demand for both tradable (T) and nontradable (NT) goods, RER appreciates, shifts resources from the T sector to the NT 3. This adjustment is efficient. With sectoral financial frictions it is not, because T and NT credit is missallocated Hamann (Colombia) Monetary & Macro-pru policies CBRT-BIS-IMF / 14

Booms: credit expands, demand for both tradable (T) and nontradable (NT) goods, RER appreciates, shifts resources from the T sector to the NT 3. This adjustment is efficient. With sectoral financial frictions it is not, because T and NT credit is missallocated 4. Monetary policy relaxes (pro-cyclical, ER pass-through reduces inflation) and MP policies aiming to restrain total credit dynamics may weaken T-sector misallocating further credit Hamann (Colombia) Monetary & Macro-pru policies CBRT-BIS-IMF / 14
