For every 1% decrease in interest rate, 1 /ZT Futures contract drops in price $2000.
But current interest rate on 2-Year Treasury note is only a measly 0.14%
The probability that 2-Year Treasury note interest rates will go negative -- is very low.
Even if the interest rate will go below zero - it will be like -0.005% (European deflation style).
