Inspired by his recent trip to the Halong Bay (in Vietnam) and Preah Vihear Temple (in Cambodia), Citibank trader Eric Loepp wonders if he can make an intermarket arbitrage profit using Cambodian riel and Vietnamese dong. He works on the Korean desk so his primary currency is wong. He has 100,000,000 to work with so he gathers the following quotes:

Citibank quotes Cambodian riel per Korean Wong: CMR 1.9324 = KWG 1.00

National Bank of Vietnam quotes Cambodian riel per Vietnamese Dong: CMR 2.7506 = VDG 1.00

Nomura quotes Vietnamese Dong per Korean Wong: VDG 0.3781 = KWG 1.00 With these quotes, is there an arbitrage profit opportunity, how do we know? (1 point) If so, what is his profit in wong? Now, in response to Erics trades, the banks update their quotes. If you also trade in these same currencies, can you make an arbitrage profit with the new quotes listed below? If you also have 100,000,000 to trade what is your profit from the trade? What is your profit in dollars if the current /$ quote by Citibank is 840 /$?

Citibank quotes Cambodian riel per Korean Wong: CMR 1.7648 = KWG 1.00

National Bank of Vietnam quotes Cambodian riel per Vietnamese Dong: CMR 2.9819 = VDG 1.00

Nomura quotes Vietnamese Dong per Korean Wong: VDG 0.5992 = KWG 1.00
