A trader initiated a short position in one silver futures contract on Monday, January 15, when the silver price is $15 per ounce. Each silver futures contract holds 5,000 ounces of silver. The initial silver margin requirement is $5,200 per contract. The trader deposits $5,200 per contract to meet the initial margin requirement. The maintenance margin requirement per contract is $4,700. What is the settlement price in silver on January 16 that would require the trader deposit additional funds on January 17 equal to $1500 per contract?
