Follow the bouncing peso
Business taxes are due today, which had an interesting effect on the peso. Mexican companies, which have been socking away dollars suddenly and collectively all said, “oh shit!” and ran to the exchange houses to trade in the greenbacks for Sor Juanas (and Benitos, and Jose-Marias and Nezahuacoatls)… making the peso the only “emerging market” currency to gan value against the dollar yesterday.
Or, at least that’s the rationale given for the 6.8 percent rise in the peso’s value over the last month by Bloomberg (which also reports that the peso is falling).
Must be the taxes that are confusing people. It couldn’t be the G-20 Summit, the U.S. auto bailout, or the growing consumer protests against credit card and bank lending rates, the conflicting reports from the Banco de Mexico or sunspots that have anything to do with it.
I’ve given up trying to make sense of it… I can’t spend dollars, and figure a peso is still worth a peso.

I’d suggest you buy yourself a few dollars today at the local casa de cambio, RG. Sell them back for Pesos in about 3 or 4 weeks’ time.
don’t lock up your everyday money, just any pesos you have that don’t need spending for a month or so.
