Goldman Sachs downgraded its rating on BP from "buy" to "neutral," saying the spill would impact the company's ability to do business worldwide. Previously, Standard & Poor's cut BP's credit rating to AA-minus from AA.

The Nordic bank Nordea said it had divested all its BP shares worth about 11.94 million U.S. dollars from its funds.

BP shares have lost about a third of their value in the recent six weeks since the spill occurred. With the progress in oil containment, its price rose 0.7 percent on the London Stock Exchange Monday.

BP has spent 1.25 billion U.S. dollars on the response effort to date. BP said on Monday that it will make an immediate payment of 60 million U.S. dollars to Louisiana to construct six offshore sand berms to help buffer the state's coast from the oil.
