(a) Do you want the term structure of interest rates (i.e., the plot of interest rates against maturities) to be sloped up or down? 

(b) Do you want the volatility of interest rates to be increasing or decreasing? 

(c) Do you want the volatility of the futures price change to be higher or lower than that of the forward price? 

(d) Do you want the correlation of the spot to futures to be higher or lower than that of the spot to forwards?
