More About Interest Rate

Why are Interest Rates Important?
  • They are the traffic signals of investment
  • They measure time preference
  • They calibrate risk
  • They set investment hurdle rates
  • They have a huge impact on:
  • They can fuel or crate prices of other assets like stocks and real esate
    • Low rates tend to increase the price of other assess as they become cheaper to finance and reduce discount rates
    • High rates tend to decrease the price of other assets as they become expensive to finance and increase discount rates 
Interest Rate Forecasting
  • Forecasting interest rates is extremely difficult - there are countless factors
  • Some consider it to be impossible
  • Central banks often try to forecast interest rates, but are proven incorrect over time

What Determines the Interest Rates

  • Short and long term interest rates are driven by different forces
    • Long-term rates are usually higher than short-term rates (more uncertainty)
  • Rates can be driven by Central bank Actions
    • Short term rate adjustments
    • Quantitative Easing (asset purchases) to drive long-term rates
    • Forward Guidance (Telling the markets what it plans to do)
  • Interest rates tend to move in long-term cycles:
    • 1900 - 1920 rising interest rates & inflation
    • 1920 - 1946 falling rates 
    • 1946 - 1981 rising rates
    • 1982 - 2016???? (end dates still tbd) falling rates
    • Interest Rate Cycles are Natural:  People first consume more than they can produce (rates go up), then later they have to pay it off (rates go down)
