Executive Summary

Markets navigated a volatile session Monday as Iran conflict fears, surging Treasury yields hitting 14-month highs, and a tech-led selloff weighed on sentiment — though Wall Street bounced off lows to close mixed. The single biggest development: NextEra Energy's $66.8 billion bid for Dominion Energy, which would create the largest U.S. power company, underscoring how AI-driven electricity demand is reshaping the energy sector. Overnight, Asian shares wobbled while Nvidia earnings remain the week's most anticipated catalyst.

Market Implications

The dominant macro risk heading into next week is the bond market. Treasury yields at 14-month highs aren't just a headline — they're a valuation reset mechanism. Rate-sensitive sectors (small caps, homebuilders, consumer discretionary) face the most direct pressure, and if yields don't pull back, expect continued rotation out of growth into energy and financials. The NextEra-Dominion deal is a direct expression of this: real assets, regulated utilities, and power infrastructure are where institutional money is moving as AI electricity demand creates a multi-decade capex supercycle.

The AI trade is bifurcating. Mega-cap infrastructure plays (Google-Blackstone's $5B cloud JV, Analog Devices' Empower acquisition, Morgan Stanley's raised semicap outlook) remain well-supported. But pure-play AI infrastructure names like Nebius and CoreWeave are seeing analyst caution on valuation — D.A. Davidson flagged limited upside despite long-term demand. Nvidia's earnings this week are the single most important data point to resolve this tension: a beat could reignite the broader AI rally; a miss or cautious guide would accelerate the rotation.

Geopolitically, Iran remains the wildcard. Oil eased on Trump's diplomatic comments, but the RBA's explicit mention of Iran uncertainty in its rate decision minutes shows how far the conflict's shadow extends into global monetary policy. Markets are pricing in a delayed U.S. military response, but any escalation would spike energy prices, compress margins across transportation and manufacturing, and likely trigger a flight-to-safety bid in Treasuries — which, paradoxically, could provide some relief on the yield front.
