وابستگی کوانتیال بین سهام، اوراق قرضه و بازارهای ارز خارجی - شواهد از انگلستان

In the wake of Brexit, this paper aims to provide a measure for the quantile dependence amongst different financial assets – bond, stock, and currency – within the UK market and their cross–border linkages with the European equity market. We implement a nonparametric estimation method for both the tail and quantile dependence parameters on weekly data over the period 1989-2016 using copula. Our results suggest that the contagion effects between stock and currency markets are limited, even under extreme fluctuations. We also find a weak comovement between currency and bond markets, however, evidence of asymmetry is found in the dependence structure, possibly due to the ‘risk-reward’ scenario of international investors. Finally, our results indicate a weak dependence between stock returns and bond yields, possibly due to the low-yielding gilt and the thirst for income, pushing investors to diversify globally into other financial markets.
