In her latest sciolistic letter to me, @SenWarren made it clear that she knows even less about foreign exchange markets than she does about banking. What is equally shocking, but not surprising: not a single member of the media mob has a rudimentary-enough level of financial market literacy to spot her remedial error. To reiterate: under @POTUS, the United States delivers for America’s trusted partners. For a fuller explanation, I recommend Senator Warren take any entry level course in international finance for her and her staff, or I can personally give her a tutorial on Foreign Exchange for Dummies. Although I am not holding my breath, I hope her next letter will demonstrate that she has learned the difference between a currency purchase and a swap or a loan.
