Non-Fundamental Flows and Foreign Exchange Rates
Frequent, yet uninformed, fund flows in Chilean pension plans generate substantial trading in currency markets due to the high allocation to international securities. These non-fundamental flows have a significant impact on the Chilean peso, which is estimated to have a relatively low price elasticity of 0.81. Hedging by the banking sector propagates the price pressure to currency forward markets and results in violations of the covered interest rate parity. Using trading data and bank balance sheet data, we confirm that regulatory requirements and banks’ risk bearing constraints create limits of arbitrage.
