The correct answer is B, Inflation risk. Government National Mortgage Association (GNMA or Ginnie Mae) securities are backed by the full faith and credit of the U.S. government, meaning they have virtually no credit risk. Investors are assured of receiving both principal and interest payments even if borrowers default, eliminating choice A.
However, like all fixed-income securities, Ginnie Mae mortgage-backed securities are subject to inflation risk, also known as purchasing power risk. Inflation erodes the real value of future interest payments and principal. If inflation rises, the fixed payments received from these securities will be worth less in real terms, reducing the investor’s effective return.
Choice C, Liquidity risk, is less applicable because GNMA securities are actively traded in the secondary market and generally have good liquidity. Choice D, Currency risk does not apply because these securities are denominated in U.S. dollars and are not exposed to foreign exchange fluctuations.
Additionally, while not listed as an answer choice, GNMA securities are also subject to prepayment risk, meaning homeowners may pay off their mortgages early when interest rates fall. However, among the given options, inflation risk is the most relevant, making choice B the correct answer.
