UK stock futures declined Tuesday as investors digested a busy earnings day across the FTSE 100. Major companies including BP, HSBC, and AstraZeneca reported results, driving sector-specific moves. The blue-chip index's futures slipped 0.4% in early trading, reflecting cautious sentiment ahead of the Bank of England policy decision later this week.

Energy and financial stocks led declines after mixed earnings updates. BP shares fell despite beating profit estimates, as weak refining margins offset upstream strength. HSBC revenue missed forecasts amid lower net interest income, pressuring banking peers. Meanwhile, AstraZeneca rose on strong oncology sales growth.

Traders await UK inflation data and BoE guidance for directional cues. The pound held near $1.27 against the dollar, while gilt yields edged higher. Market focus remains on whether earnings momentum can sustain the FTSE's recent outperformance versus European peers.
