Our history and that of the region is paved with stabilization measures based on the exchange rate, which generated severe setbacks, and ended in balance of payments crisis, financial turmoil and economic disasters. For this reason, we have evolved into a floating exchange rate regime, which permits to better reconcile the stability of the Chilean economy with the volatility of the external scenario. This is not the time or the place for a lengthy discussion on the subject; suffice it to recall that every economic crisis in Chile over the past fifty years – except the recession of 2009 we are leaving behind with unprecedented vigor – have been associated to exchange rate misalignments and rigidities. Furthermore, a very significant element to explain why the emerging economies were spared the worst effects of the recent global crisis was that their currencies floated, which allowed them to absorb the shocks, eliminated the invitation to investors to wager against currency weakening and opened room to relax monetary policy and provide liquidity. However, although a floating exchange rate has many advantages for economic and financial stability, it may happen that, at times of high uncertainty or excessive optimism, financial flows could persistently push the real exchange rate away from its medium- and long-term fundamentals, with negative effects on the economy. In such situations, the Central Bank may intervene in the foreign exchange market with the purpose of mitigating or eliminating these imbalances.
The evidence in credit creation is so far mixed, which is not in my view a mark of the failure of policy since this operates with a lag. But it does indicate that all of us should go on looking for changes that will help. The distribution and information issues around SME lending identified by Kate and her colleagues are one such area, and in my view more focus needs to be put on the consequences of debt overhangs linked to commercial property in those parts of the market where there are problems.
