The Forward Price of Gold (ignores the gold lease rate)
If the spot price of gold is S and the forward price for a contract deliverable in T years is F, then
F = S (1+r )T
where r is the 1-year (domestic currency) risk-free rate of interest.
In our examples, S = 1400, T = 1, and r = so that
F = 1400(1+) = 1470
