Expectation theory
Interest rate for a long term investment provides future expectation for interest on short term investments
for example; consider 2 year loan with higher interest rate then a 1 year loan. Then one year from now the interest rate on the 1 year loan is expected to be higher than the current interest of the 1 year loan.
