A risk analyst at a commodity trading firm is conducting an analysis of the supply and demand dynamics for commodities, specifically focusing on the medium-term volatility of silver's forward prices. Currently, the spot price for silver is USD 20.35 per troy ounce, and the 6-month forward price is USD 20.50 per troy ounce. Considering that after a 6-month period the lease rate is anticipated to surpass the continuously compounded risk-free interest rate, what will be the accurate description of the silver forward curve at that time?
