[Stele of Narâm-Sîn, king of Akkad] The Federal Reserve continues to keep its benchmark interest rate target pegged to a range of 0.25% to 0.50%. That's low. Interestingly, rates aren't just low within the context of American history. They also happen to be at the lowest levels in the last 5,000 years of civilization. Citing a speech by Bank of England chief economist Andy Haldane, Bank of America Merrill Lynch's Michael Hartnett and his team previously shared the following chart, which shows just how low today's rates are relative to other times in history: [screen shot 2015 09 18 at 10.12.09 am] Haldane's list of sources for this is pretty staggering (you can look through them all here). So to make things a bit clearer, we put together an annotated list of key historical episodes and the corresponding interest rate of the time, using the data from "The Trader and his Shadow."
