We study the effects of a price transparency shock in the Brazilian equity lending market, an over-the-counter market. Previously, the available loan fee benchmark was the mean loan fee of the past 15 trading days. On March 1, 2011, this interval was reduced to three days, significantly improving short-sellers’ ability to predict current loan fees. We find that after the benchmark change, loan fees fell, lending volume increased, total lending revenue remained stable, high-cost lenders lost market share, and price efficiency increased. Our results suggest implementing price benchmarks in OTC markets can improve market quality.
