BP Plc has put its UK North Sea oil and gas assets up for sale, the latest move in Chief Executive Meg O'Neill's portfolio overhaul aimed at repairing the balance sheet and improving profitability.

The energy major also placed its biogas unit on the market. The asset sales are designed to help BP meet its debt target ahead of schedule—a metric fixed-income investors are watching closely as they assess the company's corporate credit risk.

Accelerated debt reduction lowers financial leverage and can compress spreads on BP's corporate bonds, reducing the cost of future borrowing and improving its credit profile.

Czech entrepreneur Daniel Kretinsky, a current shareholder, reduced his stake by selling more than two percent to Jakub Havrlant. Kretinsky said the move was subject to a pre-emption process, signaling the ownership transition remains ongoing.

That legal process has directly frozen a £100 million loan earmarked as West Ham United's transfer budget. The funds are now unavailable for player acquisitions this summer.

The timing is damaging for West Ham. The club already faces a financial reset following relegation, and the blocked loan compounds those constraints ahead of a transfer window when rebuilding capital is critical.

Equity markets rose sharply. The S&P 500 gained 1.8 percent to 7,739, the Dow Jones Industrial Average climbed 1.9 percent to 54,178, the Nasdaq Composite rose 2.6 percent to 26,579 and the Russell 2000 added 2.0 percent to 3,040.
