MADRID, Dec 12 (Reuters) - Spanish lender Popular is finalising the sale of a 1.14 billion-euro ($1.5 billion) portfolio of distressed consumer loans, as the country's banks start clearing their books of troubled assets.
Popular, which unlike some other Spanish banks has not tapped European aid even though it failed a September stress test on its finances, is close to selling the loans to Nordic distressed debt group Lindorff and financial services-focused private equity firm AnaCap, a source familiar with the matter said.
Popular said no deal had yet been signed and declined to give details on any possible sale, though the source said the deal could be formalised later on Wednesday.
Such portfolio sales, including troubled assets or corporate loans, are starting to gather pace in Spain, as lenders scramble to shore up capital following a five-year-old property downturn.
Popular shrank its capital gap with a 2.5 billion euro ($3.3 billion) rights issue of new stock completed in early December.
All banks have made provisions for losses on toxic real estate loans or foreclosed properties, which should help them withstand sales of these types of assets at big discounts, which many had so far been resisting.
More deals in the property sector or on other portfolios such as consumer loans are likely to take place early next year, bankers in Madrid said.
"There is a lot more investor interest," said one banker, adding that private equity firms or distressed debt specialists such as U.S. groups TPG and Fortress were among those eyeing Spain. Other advisers on such deals have previously cited those firms among potential bidders for Spanish assets.
"The difference between the bid and the ask price has narrowed a lot," the banker said.
The portfolio shed by Popular, of troubled consumer loans including to immigrant clients, was completely provisioned for, meaning the bank will not take an additional hit even if they are sold at a discount to their original face value.
The total price paid was not immediately clear, though the source familiar with the matter said Popular could actually book a gain of over 30 million euros from the sale.
Popular also completed a buyback of various securities on Wednesday, which will yield capital gains of 45 million euros, the source said.
Both deals will bring the bank closer to booking the 300 million euros in capital gains it is eyeing for 2012, after already raising 124 million euros towards that in the first half of the year.
Popular had a capital gap of 3.2 billion euros, according to an independent audit of the bank in September evaluating how lenders would weather a serious downturn, though its recent rights issue went some way towards bridging that.
Popular said on Wednesday that 154.8 million euros, or 10.8 percent of institutional bondholders, had accepted a buy-back offer for subordinated, preference shares and securitised debt instruments worth up to 1.43 billion euros.
Distressed funds typically look to pick up toxic loans at rock bottom prices, while until recently banks had been reluctant to contemplate selling anything below 50 percent of face value, banking sources said.
But like peers across Europe, Spanish banks want to shrink their bloated balance sheets, to help them meet stricter global capital requirements.
They are also contemplating sales of healthier loans as a result. Spain's biggest bank, Santander negotiated the sale of 2.5 billion euros of a mixed bag of loans to Bank of America Merrill Lynch in October.
Number two bank BBVA had by then sold about 1 billion euros of loans on an individual basis in 2012, sources said. ($1 = 0.7693 euros) (Additional reporting by Robert Hetz; Editing by David Holmes and Helen Massy-Beresford)
