Mexico is the new focus of the Latin American economies, as the banking industry is in a growth spurt. Investors could consider the exchange traded fund for diversified portfolios as the middle class expands and wages rise.

“The demand for bank stocks in Mexico is very large right now,” said Gerard Cassidy, an analyst at RBC Capital Markets. “When you look at global asset managers and then look at Latin America, Mexico is the new ‘in-region’ to be in. And within that, the best way to play the country’s economy, of course, is through a bank. There aren’t many banks that are publicly traded in Mexico.”

There are only two publicly traded banks in Mexico currently, and Santander Mexico is one of them. There is $58 billion in assets and about 1,000 branches in Mexico, and the Spanish parent company still owns 75%, reports Marie Beerens for Investor’s Business Daily.

The Mexican economy is forecast to grow 4% in 2013, more than Brazil and Chile. The biggest contributor to Mexico’s banking sector is expected to be the credit sector. Along with the growing middle-class and rising wages, the economy in Mexico is in a good position. The manufacturing sector makes up about 18% of the economy.
