Asset Allocation Spotlight: Economic forces that influence markets and portfolios

  • We recently adjusted the economic growth and inflation targets, and they are still in line with the nearly 40-year averages.
  • A portfolio’s sensitivity to economic growth and inflation can be used for asset class positioning for changes in the macroeconomic environment.

Equities: High bandwidth memory reshaping the memory industry

  • Prior to the Iran conflict, artificial intelligence (AI)-led high bandwidth memory (HBM) capacity was mostly sold out for the entire calendar year 2026. Despite the Iran conflict, we expect momentum in AI-led HBM investments to continue.
  • The memory industry has prioritized reallocating their Dynamic Random Access Memory (DRAM) capacity investments toward manufacturing HBM used in AI servers, which has contributed to the recent dramatic rise in DRAM pricing.

Fixed Income: Municipal bonds — we think value can be found

  • As we move through the second quarter of 2026, we believe the municipal (muni) bond market presents a compelling opportunity following a meaningful muni bond price reset.
  • In our view, muni bonds potentially stand out as a destination for investors seeking income, diversification, and potential resilience in an environment marked by equity volatility and geopolitical uncertainty.

Real Assets: Why West Texas Intermediate is trading above Brent

  • The historical premium that Brent crude trades over West Texas Intermediate (WTI) has inverted since the outbreak of the U.S.-Iran war.
  • We view the reverse Brent-WTI relationship as a logistical issue tied to geopolitical disruptions rather than a sustained global supply shortage.

Alternatives: Private equity recovery has been uneven

  • Private equity recovery was uneven in the first quarter, with buyout activity largely flat and venture capital showing a material rebound.
  • Looking ahead, we believe a gradual and selective recovery appears most likely, as we expect AI concentration, geopolitical ramifications, softer private credit supply, and a backlog of pending exits to continue to pose challenges.
