Markets opened strong today after the Federal Reserve pledged to hold down interest rates, saying it would keep rates near zero for a "considerable time." Markets also got a lift from a move by China's central bank on Thursday to cut short-term borrowing costs for banks.

Throughout the day, economic reports including a decline in jobless claims by 36,000 to a lower-than-expected 280,000 for the week ended Sept. 13, gave the U.S. stocks a boost.

The global markets also were keenly focused on developments in Scotland's independence vote, where more than 4.2 million voters cast their ballots. The polling places are expected to close at 10 p.m. Edinburgh, Scotland time or 5 p.m. EDT.

According to USA Today, Scottish independence would take with it "one-third of the United Kingdom's land mass, 8% of its population, about 10% of its tax revenue, and an incalculable amount of cultural and intellectual capital."

As the world watched the referendum closely, traders have surprisingly sent the British pound to fresh multi-year highs vs. the euro and multi-week highs against the greenback. David Rodriguez, quantitative strategist at DailyFX, said foreign exchange traders sent overnight volatility prices on the British pound to their highest since the last U.K. general election in 2010, unable to dismiss the threat of a major upset if Scottish voters did indeed vote for secession.

"Many traders have closed GBP-short positions in a hurry on what promises to be big volatility as results come in," said Rodriguez. "The lack of actual vote results and a ban on exit polls tells us this [increase] is largely a technical correction."

The pound gained 0.6% against the U.S. dollar Thursday hitting as high as 1.64078. The pound-euro exchange rate rose 0.2% after hitting a high of 1.2731.
