The forward price falls. Convenience yield is a benefit of holding the physical asset, and it offsets financing and storage costs in the cost of carry. A larger benefit lowers net carrying costs, so the no-arbitrage forward price is lower.

  1. Arise, because storage becomes more valuable
  2. Bfall, because holding the physical asset provides greater benefitsCorrect
  3. Cstay the same, because convenience yield is not observable
