Decoupling

While the U.S. economy is struggling to break its slump, growth remains strong in other places around the world - so strong, in fact, that analysts are breaking out a term that's spend much of the past two years on the shelf: De-coupling.

U.S. gross domestic product (GDP) will meandered along with a meager 1.7% expansion in the second quarter and is expected to grow by less than 2% for the full year.

Meanwhile, Brazil's GDP is on pace to expand by 7.5%, India's economy is projected to grow by 8.5% and China's economy is expected to grow by 9.5% this year.

Emerging market economies are moving ahead at such a brisk rate that their combined GDP will be bigger than developed countries by 2015, according to the World Bank.

Now, the biggest Wall Street firms - including Goldman Sachs Group Inc. (NYSE: GS) Credit Suisse Group AG (NYSE ADR: CS) and Bank of America (NYSE: BAC) - are betting that the global economy has de-coupled from the United States, and will shake off any slowdown in the world's largest economy.
