LONDON--The British pound and U.K. stocks surged on Friday after Scotland voted to stick with the rest of the U.K., reviving international investors" appetite that had waned amid uncertainty in recent weeks.

Shares in Royal Bank of Scotland Group PLC and Lloyds Banking Group PLC, which both have substantial exposure to Scotland, soared.

The pound, which slumped earlier this month when opinion polls suggested the referendum would be a close vote, rushed to a two-week high of $1.6526 as results trickled in during Asian trading hours. It also hit a more than two-year high against the euro.

"There will be collective sigh of relief as a period of huge uncertainty has been avoided," said Alan Wilde, head of fixed income at Baring Asset management. "This will calm markets, which had become increasingly nervous in the last few weeks."

Analysts said the pound may climb to $1.66, but some thought gains would be hard fought, particularly since it rallied Thursday in the immediate run-up to the vote. "The pound's better than the euro, but has already gone a long way, and is not going to hold these levels against the dollar," said Kit Juckes, a currencies analyst at Société Générale in London.

The FTSE 100 index rose 0.7% in early trade to 6,864--its highest level in around two weeks.

"While the decision is in line with most people's central expectation--including our own--the removal of the risk of a U.K. breakup is nevertheless positive for U.K. assets," said Kevin Daly, an economist at Goldman Sachs.

But Bill O'Neill, head of investment office U.K. at UBS Wealth Management said that any relief rally, might be more limited than some expect. "Investors decided early on in this campaign that there would be a "No" victory, and confidence returned to the markets well before voting day," he said. "There will be a relief rally, but it will be limited because the market has not aggressively accounted for a "Yes" vote," he added.

The yield on the two-year Gilt, or U.K. government bond, was at 0.90%, 0.03 percentage points higher on the day, reflecting strengthened expectations that the Bank of England will raise interest rates in early 2015. Yields rise as bond prices fall.

Thursday's rally wasn't limited to the U.K. Spanish bonds led the way as riskier eurozone bonds rallied. The yield on the country's 10-year bond fell 0.1 percentage point to 2.18%, the lowest since Sept. 9. Spanish debt has suffered in recent weeks as investors fretted that a vote for Scottish independence could boost separatist movements inside Spain, with Catalonia planning its own breakaway referendum. Spain's Ibex stock index rose 1.5%.
