The interest rate a government must pay to obtain buyers for its bonds depends on the supply and demand of competing financial assets. Governments desire to sell their bonds at the lowest interest rate possible. Suppose the government sells a large number of consuls at 5% interest. The next year the demand for consuls drops and the government has to raise the interest rate to 10% to attract buyers. What happens to the price of the consuls issued at 5% interest. To see what happens suppose a buyer of a 5% consul tried to sell his consul in a market where buyers could buy 10% consuls. If a buyer bought a 10% $1000 consul he would receive $100 a year. The price of the 5% $1000 consul would have to fall to $500 in order for the buyer to obtain 10% interest. The buyer would be indifferent between purchasing two of the old 5% $1000 consuls at $500 each or one of the new 10% $1000 consuls. In either case he would receive $100 a year for his $1000 investment. The price of consuls adjusts such the interest payment equals the market rate of interest.

The purpose in introducing consuls was to eliminate the problem with the time horizon of current bills, notes and bonds. Currently at the end of the stated time horizon, for example a 30 year bond, the government pays back the principal in full. What this means the longer the time horizon before repayment of principal the more the bond acts like a consul. For short term debt the price changes only slightly with varying interest rates. The longer the time horizon the greater the change. New 30 year bonds act approximately like consuls.

The higher the interest rates the lower the value of the stock market. To clearly understand why this is so consider the choice of an investor. The higher the interest rate the government is willing to pay on its bonds the more investors forgo the stock market to obtain sure thing rewards from the government. The price/earnings ratio of stock falls until stocks are competitive (based on earnings) with bonds at higher interest rates.
