The new fiscal package planned by the Mexican government this week helped Mexico maintain its "investment grade" rating from risk experts at Moody's.

Financial experts J.P. Morgan also expressed confidence that the grade would be retained by other agencies.

The confirmation of the grade from Moody's indicates they have faith in the new government budget and remain confident that Mexican government bonds and other investments in Mexico are a lower risk than many other emerging market economies.

In a recent report, Moody's said, "Mexican mutual fund investors now number almost two million in more than 500 fixed-income and equity funds ... Mexico can now boast of being the second-largest mutual fund market in Latin America behind Brazil and is one of the fastest growing markets in the world."

A little like credit ratings for individuals, such investment grades for countries indicate the level of risk for investing. They take into account political risk and are used by investors looking to put money into overseas financial markets.

Two other large credit rating agencies, Fitch and S&P, are expected to publish their latest grade for Mexico in the coming days.
