A graphical plot of interest rates on government debt securities (Treasury Bills) of varying maturities can have one of three shapes; increasing, decreasing, or flat. The data below show the interest rates on the government of Ghana debt securities (Treasury Bills) on two separate dates; 31st January 2019 and 4th May 2020.

182 Day TBill	15.10%	15.31%
364 Day TBill	17.38%	16.92%

What reasons would you assign for these upward sloping shapes of the yield curve in Ghana on these separate days? Your explanation should be practical and as detailed as possible but not exceeding 800 words
