Equities broadly face headwinds: strong earnings lift sentiment, but the macro backdrop of higher-for-longer oil prices and postponed rate cuts constrains upside. The S&P 500 rallied to all-time highs on earnings optimism, yet strategists remain cautious about sustainability.

Sceptics note that demand destruction could yet emerge in Europe and other mature economies if prices remain elevated, easing supply pressure and limiting the durability of the inflationThe rate at which prices rise across an economy. narrative. Additionally, unexpected diplomatic breakthroughs or a ceasefire could rapidly reverse oil's gains and restore rate-cut optimism. For now, however, the market is pricing in structural, not transitory, supply disruption.
