Suppose you buy a British Bond for £ 1000 and it pays £ 80 in interest over a year. When you purchased the bond, the pound sold for TZS 1.80, however, it has since slipped to TZS 1.50, due to lower interest rates in the UK. What was your TZS rate of return? when the bond rises to £1,020 over the year due to the lower UK rates.
