Tomoko Matsubara is a currency arbitrager for Showa and Company in New York. The spot rate this morning is $0\mathrm{.}0082987$ $$/$ and early indications are that the $90-$day US interest rates will raise from their current level of $8\%.$ The $90-$day forward exchange rate quoted to Matsubara$-$san by local banks such as Daichi Kangyo are all about the same $0\mathrm{.}0089612$ $$/.$ The current $90-$day yen interest rate is $4\%.$ Matsubara can borrow up to $$2$ Million. Can you help her design a currency interest arbitrage against the Yen.
