There must have been an idea session at Los Pinos in the last couple of days.
Earlier today, Calderón proposed using the money in Afores (Mexico's retirement accounts) to pay for infrastructure projects, which Mexico has had a hard time funding in recent years. Presently, the money sits in one of two dozen or so mutual funds, administered by a handful of different banks. I have no idea what is the risk involved or therefore whether or not is a credible idea, but much of Mexico needs new infrastructure investment. My dream project would be a triangle train between Monterrey, Mexico City, and Guadalajara.
Update: Carstens discounts the risk, calling the plan "very safe".
