Why would you invest in either? Buy high and sell low??? And, with the current yield of either you would just lose based on current rate of CPI. Have you thought of alternatives? Corporates, high yields, municipals, zero coupons, etc.?
Maybe some of you should look at the Mexican central bank policy on supporting the peso! That is why the peso has been dropping from 14.60 at 5 am to its current 14.27! And Mr know-it-all the lack of participation in the stock market is not the reason for the fall of the peso but rather the fear factor of the unknown which is driving investors to US bonds and GERMAN bunds!!!
