Abstract:
Prior to the series of manipulation scandals, financial benchmarks were perceived as a competitive and objective reflection of underlying money markets (Stenfors and Lindo 2018). For example, the manipulation of the London Interbank Offered Rate (LIBOR), underpinning financial contracts worth trillions of dollars was unthinkable. To prevent manipulation, financial market regulators around the world have recommended a paradigm shift from estimation-based to transaction-based financial benchmarks. This shift is based on the mainstream economic view that financial benchmarks anchored on actual transactions are not susceptible to anticompetitive behaviour. However, unlike auction markets, underlying interbank money markets have unique features. As most activity takes place over-the-counter, they are opaque and are governed by conventions, trust and reciprocity. This complicates the achievement of competitive pricing. Using a novel dataset from Bank of Zambia, this paper makes an empirical investigation into transaction-based benchmarks’ susceptibility to anticompetitive behaviour. Additionally, it contributes to the theoretical understanding of transaction-based financial market benchmarks. The study reflects on financial market regulators’ recommendation to transit from estimation-based to transaction-based financial market benchmarks. Further, the study is of interest to central bankers, as short-term interbank rates are the first stage of the monetary transmission mechanism.
