An Indian importer observes the following quotes in the
interbank market: Direct Quote in India:Β 1 USD = βΉ83.50 Indirect Quote in India:Β 100 INR = 1.22 USDΒ Β Β Β Β Β Β Based on these quotes, which of the following statements is mathematically accurate regarding the relationship between these two rates?Solution
A Direct Quote is 1 πΉππππππ ππππ‘ = π π»πππ ππππ‘π i.e. 1 USD = βΉ83.50. An Indirect Quote is 1 π»πππ ππππ‘ = π πΉππππππ ππππ‘π i.e. βΉ100 = 1.22 USD Β or βΉ1 = 0.0122 USD Β To compare, find the Implied Direct Rate from the indirect quote: Β = 1/indirect quote = 1/0.0122 = 81.967 Β As βΉ81.97 (as calculated) is lower than βΉ83.50 (Directly quoted), the USD is cheaper via the indirect route, creating a potential arbitrage opportunity.
