* Benefits from strong market
* Lenders also want to stay in favour with oil powerhouse
* Latest borrowing smaller than expected

LONDON, Jan 25 Rosneft has requested better terms on part of its financing to buy TNK-BP, banking sources said on Friday, taking advantage of strong market conditions and the desire of lenders to stay in favour with the Russian oil powerhouse.
Rosneft, which will be the world's largest listed oil producer after the acquisition, has cut 10 basis points (bps) from the interest margin of a $13 billion loan, the second part of a $29.8 billion financing package for the $55 billion purchase of its Russian rival.
"Rosneft's price cut is a token amount and it should not fundamentally change lenders' analysis, plus people have to make an overall call on their relationship with the borrower," one banker close to the deal said.
The reduction reflects strong market conditions in Central and Eastern Europe where borrowers can achieve more favourable terms from international banks fighting for market share after weak deal flow in 2012.
The change in pricing will be formally confirmed after banks have submitted commitments next week. All banks are expected to accept the new pricing, a second banker said.
The borrowing is smaller than a $15.7 billion loan that was originally discussed because a UK bank declined to participate, bankers said.
Rosneft, which is buying 50 percent of TNK-BP from AAR, a consortium of four Soviet-born tycoons, raised $16.8 billion in December to buy BP's half of the venture.
The latest borrowing consists of a term loan and bridge loan to a bond issue. The term loan is priced at 200 bps after the cut and the bridge loan is priced at 140 bps.
Rosneft could not immediately be reached for comment.
Bank of Merrill Lynch and Citigroup are co-ordinating both stages of the jumbo loan.. Neither bank would comment.
The latest financing is expected to sign by mid-February at the latest.
