Yep, S&P finally took the initiative; possibly after the questioning of entire rating system during sub-prime crisis. Greece's sovereign rating was downgrade to Junk (BB+), Portugal downgraded two notches to 'A-' and Spain downgraded one step to 'AA' sending jitters down the spine of stock markets worldwide.
As a preliminary analysis, I can think of two things
a) Gold: The commodity could see some downward pressure on the possibility of the countries nearing debt/interest repayment selling part of their Gold reserves to payoff the interest on the debt or part of it. For the medium to long term, the current scenario could be positive for Gold. The downgrades in the 'Euro' countries would put southward pressue on the 'Euro' currency. Holders of Euro would like to switch to a safer currency or to Gold which is the ultimate store of value.
b) Emerging market equities: The downgrades and the possibility of crisis does not bore well for equity markets especially of emerging countries. Increase in Risk Aversion in Western countries would result in outflow of FII money which has been the primary reason for stock markets running amok. Obviously the Westerners would like their money to be parked in perceived safe zones like US treasury. Also, at a P/E of over 20, Indian equity markets are not cheap either.
And yes, the last recession was due to Greed of bankers to create Mortgage Baked Securities out of sub-prime, graded high by so called rating agencies; sold to unassuming investors. This one could possibily due to a tale of debt, downgrades and defaults, flagbeared by Greece.
A view from technical perspective in my next article.
