Abstract
We study the interdependence of FX and Treasury Bonds (TES) markets in Colombia. To do this, we estimate a heteroskedasticity identified VAR model on the returns of the COP/USD exchange rate (TRM) and bond prices, as well as event-analysis models for return volatilities, number of quotes, quote volume, and bid/ask spreads. The data under analysis consists of 5-minute intraday bid/ask US dollar prices and bond quotes, for an assortment of bond species. For these species we also have the number of bid/ask quotes as well as their volume. We found, also, that the exchange rate conveys information to the TES market, but the opposite does not completely hold: A one percent COP depreciation leads to a persistent reduction of TES prices between 0.05% and 0.22%. However, a 1% TES price increase has a very small effect and not entirely significant on the exchange rate, i.e. a COP appreciation between 0.001% and 0.009%. Furthermore, TRM return volatility increases do not affect bond return volatility but its liquidity, i.e. the bid/ask quote number and volume. These results are coherent with the fact that the FX market more efficiently reflects the effect of shocks than the TES market, which may be due to its low liquidity and concentration on a specific habitat. These results have implications for the design of financial stability policies as well as for private portfolio design, rebalancing and hedging. **** RESUMEN: Analizamos la interdependencia entre los mercados de divisas y bonos (TES) en Colombia. Para esto estimamos modelos VAR identificados por heterocedasticidad para los retornos de la tasa de cambio (TRM) y los precios de los bonos, así como también modelos de análisis de eventos para la volatilidad de los retornos, el núúmero y volumen de las ofertas, y los diferenciales de compra y venta, bid/ask spreads. Los datos analizados consisten en muestras de cada 5-minutos de precios bid/ask del dólar y de ofertas de los bonos, para un conjunto de referencias. Para estas referencias también contamos con el número de ofertas bid/ask así como su volumen. Encontramos que la TRM transmite información al mercado de bonos, pero lo opuesto no se da completamente: una depreciación de 1% del peso produce una reducción permanente del precio de los TES de entre 0.05% y 0.22%. Sin embargo, un incremento de 1% del precio de los bonos tiene un efecto pequeño y no enteramente significativo sobre la TRM, i.e. una apreciación del peso entre 0.001% y 0.009%. Adicionalmente, los incrementos en la volatilidad de la TRM no afectan la volatilidad de los retornos de los bonos, pero si su liquidez, es decir, el número y volumen de sus ofertas. Estos resultados son consistentes con el hecho de que el mercado de divisas refleja de manera más eficiente el efecto de los choques que el de bonos, resultado de la baja liquidez y concentración en un hábitat específico de este último. Estos resultados tienen implicaciones importantes para el diseño de políticas de estabilidad financiera, así como también para el diseño de portafolios privados, su rebalanceo y cobertura.
