The JPY/AUD Carry Trade and Its Causal Linkages to Other Markets

Abstract

This study analyzes the causal structure underlying the popular Japanese Yen/Australian Dollar (JPY/AUD) carry trade and related financial variables. Three causal search algorithms are employed to find the relationships amongst the JPY/AUD exchange rate, the S&P 500 stock index, the Nikkei 225 stock index, the Australian Securities Exchange 200 stock index, the 10-year U.S. Treasury Note, the 10- year Japanese government bond, and the 10-year Australian government bond. The results from all three algorithms provide evidence against the theory of uncovered interest rate parity.
