“It’s wrong to just take to periods and look at empirical data to forecast out. You need theory to explain the moves and any similarities. The similarities come about based on Austrian Business Cycle Theory, which says a slowdown in money printing results in a shrinking in the capital structure of the economy. As a result there is upward pressure on interest rates, as those seeking funds must bid up rates to entice investors. It such a slowdown in money growth occurring? It sure is. Just like it did in 1929, 1987 and 2008.”
