* Any listing years away, bankers say
* Glencore declines to comment
* Secretive nature has given it bumpy ride in CDS market

LONDON, June 19 (Reuters) - Glencore International AG's bumpy ride in credit markets over the past year may prompt it to seek a public listing but not for a few years, said bankers familiar with the commodity trader's thinking.
Talks about an Initial Public Offering (IPO) are taking place regularly, the bankers said, now that the secretive Swiss-based group -- founded by Marc Rich and now one of the world's biggest private companies -- is looking for more financial leeway.
"I'll be surprised if they were to sell a big chunk of their shares now. If you are talking about the next three to five years, that's possible," one of the bankers said.
The Financial Times reported on Friday that the group is exploring a stock market listing to overcome the constraints of its private ownership structure, a possible barrier to growth. The company declined to comment.
Glencore's opaqueness manifested when the cost of buying protection against default on its debt jumped to more than 3,000 basis points, a level way out of line with its investment grade credit rating.
But its credit default swap (CDS) spreads have since fallen to an eight-month low, tightening another 50 basis points on Friday to 625 basis points after the report.
"The company is currently reliant on the debt markets for funding, and the experience of the past nine months has highlighted the limitations of this model," credit analysts at RBS said in a research note.

SECRECY
A listing would require Glencore, founded in 1974, to shed its secrecy and become transparent, opening up its huge and successful oil, coal and metals trading operations to scrutiny.
An IPO could give Glencore a market value of between $30 billion and $40 billion, Liberum Capital estimated.
Rich, the former U.S. fugitive who was pardoned by President Bill Clinton in 2001 after 18 years in Switzerland to flee charges of financial crimes, sold Glencore to management.
"When a generation that have built the business wants to leave in the next decade or so, where will the capital come from to buy them out of the partnership? New partners certainly can't afford to buy their equity," Liberum said in a note.
Based in the affluent town of Zug, known for its low corporate tax rate, the company has grown from a trading enterprise into a major producer of raw materials, owning about 35 percent of UK-listed miner Xstrata.
It also holds stakes in U.S. Century Aluminum, Russian oil producer Russneft and aluminium giant Rusal, and Australia's Minara Resources.
One of the reasons why the idea of a listing seems credible are recent perceptions that the company has liquidity problems, a concern that has hurt Glencore's CDS in the past. But analysts said they were comfortable with its liquidity.
The recent signing of a $6.7 billion forward-start agreement, a type of loan, and a $8.2 billion revolving credit facility showed the strong relationship the company has with its banks, UniCredit said.
"This is not the moment to take action. Glencore has no liquidity problem," another banker said.
Standard & Poor's, which downgraded Glencore's debt to BBB- last December, the lowest investment grade rating, said the group will hit a refinancing need in May 2011, when $7.3 billion of its debt matures.
In March, Glencore reported in a one-page financial highlights statement that 2008 earnings before interest, tax, depreciation and amortisation fell to $6.79 billion.
Another option for the group would be a merger with Xstrata, Evolution Securities said in a note.
"(An IPO) would create too many public conflicts were Xstrata to remain a separately quoted associate in view of the trading links between the two organisations," Evolution said.
"Much better, we think, for Glencore and Xstrata to merge and thereby consolidate their position through cutting the overlaps that exist between the two groups."
