Oil prices rose Sunday while US stock-index futures advanced, reflecting investor uncertainty over the escalating US-Iran conflict. The moves come as both nations continued trading fire in the Persian Gulf, renewing fears that the Strait of Hormuz may effectively close again.

Adding a contradictory signal, Bloomberg reported that equity-index futures specifically climbed on news that both sides backed away from fresh escalation. That glimmer of progress, however, sits uneasily alongside MarketWatch's account of continued airstrikes, leaving the fragile ceasefire underpinning peace talks in doubt.

MarketWatch noted oil's climb alongside the stock futures gain, while Bloomberg described oil paring its earlier climb following the peace-talk reports. No specific percentage moves were provided by either outlet, making the magnitude of price swings unclear.

The competing narratives leave traders parsing ambiguous signals: one source points to ongoing hostilities threatening global shipping lanes, the other to diplomatic backpedaling that could ease tensions. The Strait of Hormuz, a chokepoint for about 20% of the world's oil, remains the key variable. If reports of de-escalation prove premature, energy markets could face sharper volatility in coming sessions.
