President Donald Trump is a huge fan of low interest rates. He's even gone so far as to praise Germany for its 0 percent interest rate, and referred to the Federal Reserve as "boneheads" for not taking U.S. rates lower.
Recently, countries like Denmark, Sweden, Germany, Japan and even the European Central Bank have taken rates into negative territory.
