President Nicos Anastasiades vowed on Friday to keep Cyprus in the euro but had harsh words for international lenders behind the huge bailout that saved the island from bankruptcy.

The central bank later lifted curbs on domestic credit card payments and said it would make daily efforts to relax the wider controls that it imposed to avert a bank run, the first of their kind in the eurozone.

The finance ministry announced on Friday night that restrictive measures were being extended by five days, with a central bank spokeswoman clarifying that this meant through next week.

"The week after, we will review the situation," said Aliki Stylianou.

Banks resumed normal trading hours on Friday the day after they reopened peacefully following a nearly two-week shutdown as Cyprus negotiated a 10-billion-euro ($13-billion) rescue package.

The deal with the "troika" of the European Union, European Central Bank and International Monetary Fund imposed a levy on large deposits, causing jitters among other eurozone strugglers and worrying investors.

Rightwinger Anastasiades, who was elected in February on the back of a promise to secure a bailout for the small eastern Mediterranean island, said the deal had saved Cyprus from "economic collapse."

"We will not leave the euro and I stress that," he told a conference of civil servants. "We will not engage in risky experiments that will endanger the future of our country."

But he criticized other eurozone states for enforcing the tough terms of the deal agreed with the troika after all-night talks in Brussels on Monday.

"Nobody can ignore the insensitivity of our partners," he said.

He also took aim at international lenders and at the previous government for pouring money into the country's second largest lender Laiki, or Popular Bank, which will be wound up under the terms of the bailout.

Anastasiades received the backing of visiting Swedish Foreign Minister Carl Bildt, who tweeted that the EU "pumped money into (an) unsustainable situation" and "could have pulled the plug earlier."

The bailout calls for severe cuts to Cyprus's prized tax-haven style banking system -- bloated with Russian money and exposed to toxic Greek debt -- and also threatens to deepen the economic recession the island was already suffering.

The most controversial element is the unprecedented raid on deposits over 100,000 euros. Laiki, or Popular Bank, is to be wound up, and deposits there over that amount could be lost altogether. At the Bank of Cyprus, the country's largest lender, the hair cut had been expected to be around 40 percent.

On Friday night, private broadcaster Sigma TV published a copy of what it said was a central bank decree stipulating that the figure at Bank of Cyprus would be 37.5 percent, which would be converted into shares.

That sparked fears that savers would make a run on the banks when they reopened on Thursday.

But the panic never materialized, and the banks returned to normal opening hours on Friday.

Withdrawal and transfer limits have made it hard for small businesses to pay salaries and for families to make rent payments, especially as both tend to fall around the end of the month.

The central bank then moved to ease fears that the harsh controls it imposed to stop a bank run could last for far longer than their official period of one week.

"Each day, we will measure and look to refine or relax these controls with the overriding goal of safeguarding and stabilizing the Cypriot financial system," the bank said in a statement.

Hours earlier the central bank issued a decree removing the 5,000-euro ceiling on credit and debit card transactions within the country.

However, draconian controls still remain in place including a daily withdrawal limit of 300 euros and bans on cashing checks or taking more than 1,000 euros in cash out of the country.

Foreign Minister Ioannis Kasoulides has said restrictions could last for up to a month.

Economist Yiannis Tirkides warned that they could last for years.

"These controls, we don't know when they will go away," he told AFP.

"The government says it's for a week. The foreign minister says it might be for a month. But ideally when you implement controls in a country they tend to last for years," he told AFP.
