The Mexican peso is losing ground against the dollar today for the first time in seven sessions. The peso's heavier tone is consistent with the generally heavier tone among emerging market currencies today. Concerns about global growth, with softer than expected PMI readings from China and Europe, concern that China may still hike rates, and the uncertainty facing a second aid package for Greece may all be conspiring to spur some profit-taking in the peso.
During this run, the peso appreciated 2.3% against the dollar, the most in Latin America, and better than most emerging market currencies, save the Hungarian forint and Polish zloty. Part of the peso surge seems to be a function of market positioning. Throughout most of June, and actually beginning back in late April, the net speculative position at the IMM had been reduced and stood at its lowest level since last September. This coincided with the sharp cut in cetes holdings by foreign investors. Speculative players appeared to have been chasing the peso higher last week, as risk appetites returned following the successful Greek austerity vote.
