markets PM market analysis — 2026-10-08

The tone across markets turned more defensive this session. J.P. Morgan’s latest guide points to slower growth, persistent inflation uncertainty, and large-cap US equities that look expensive and heavily concentrated, with international markets appearing relatively more attractive by comparison. Trading Economics reports that US equities weakened as Treasury yields rose, energy costs climbed, and expectations built for further rate tightening, all of which dented risk appetite.

AI infrastructure shares were singled out as particularly exposed to this shift, given their sensitivity to borrowing costs and to any softening in broad market sentiment. Separately, a UK court’s decision to overturn convictions tied to alleged benchmark-rate manipulation has put renewed focus on the governance and credibility of the reference rates underpinning financial products. None of this amounts to a single dominant narrative, but the combination of higher yields, energy pressure, and equity concentration risk points toward a cautious stance for now.
