According to a Wall Street Journal report on January 28, 2015, Greek bonds maturing in 2019, issued last year at a yield of just under 5%, now yield over 13%. As a whole, Greek bonds are closing in on the highs they hit in early January when markets first began to worry about the prospect of a Syriza victory. (Greek Markets Continue to Slide, The Wall Street Journal, Jan. 28, 2015, http://www.wsj.com/articles/european-stocks-rise-1422436252?ref=/news-financial-markets-stock). Suppose the Greek bonds (1,000 par value) coupon rate was zero and the yield to maturity was 5%. Assume that exactly one year has passed since the bond issuance and there was still four years before the bond would mature. On January 28, 2014, the exchange rate between the euro and the U.S. dollar was $1.3662/. On January 28, 2015, the exchange rate was $1.1310/. As a U.S. investor, if you had purchased the Greek bonds at issuance (on January 28, 2014), what was your return, measured in U.S. dollars, if you sold the bonds on January 28, 2015?
