The New Fama Puzzle, post-ZLB
In a previous post, I documented the fact that the Fama puzzle had transformed post-global financial crisis, so that for most currency pairs, interest rate differentials pointed in the right direction for subsequent exchange rate depreciation, from 2006 through end-2015 (Bussiere, Chinn, Ferrara, Heipertz (2018)). Here I show that the new puzzle persists through the end of 2017, a period when US interest rates were rising.

The World-Wide Fama Puzzle Reversal
In my previous post, I recounted “The New Fama Puzzle” as it applied to dollar exchange rates, with focus on the euro/dollar rate. A quick observation: the reversal also appears for non-US dollar based exchange rates (against euro, yen, pound).

Interest Differentials and Exchange Rate Changes Before and After the Global Crisis
Before 2007M08
and After 2007M09
If the joint hypothesis of uncovered interest rate parity (UIP) and rational expectations –- sometimes termed the unbiasedness hypothesis — held, then the slope of the regression lines (in red) would be indistinguishable from unity. In fact, they are significantly different from that value. This pattern of coefficient reversal holds up for other dollar-based exchange rates, as well as for other currency pairs (with a couple exceptions). The fact that the coefficient is positive in the post-global financial crisis period is what we term “the New Fama puzzle”.

Making Mexico Pay for the Wall (Redux)
So we’re back to this again? From CNN:
“They can pay for it indirectly through NAFTA,” Trump said Thursday in an interview with The Wall Street Journal. “We make a good deal on NAFTA, and, say, ‘I’m going to take a small percentage of that money and it’s going toward the wall.’ Guess what? Mexico’s paying.”
