Tensions and fears are still persisting in markets where investors are worried that global econmeis, led by the United States, may head to another recession or financial crisis, triggering demand on safe haven assets.

Still, the S&P cut to U.S. sovereign rating by one step to AA+, losing its top rating for the firs time since 1941, is having negative impact on markets before the Fed rate decision later in the day.

Amid the sluggish growth and substantial debt, the Fed may be obliged to announce new measures to boost the fragile recovery. However, expectations refer to no change in monetary stance by the Fed on Tuesday meeting, which actually may lead to more fears that the agony in the U.S. economy will increase while the Fed is standing still.

Thus, with the risk stemming from the world's largest economy, mounting debt woes in the euro area and sluggish growth in global major economies, refuges remain the most attractive to investors.
