October 2026 was a month of recalibration rather than panic. Howard Marks rejected the AI-bubble thesis, China's tax authorities imposed their first comprehensive rules on offshore trusts, and the world's family offices — Citi's 351-office survey and RBC/Campden's 155-office sample alike — quietly rotated back toward public equities and toward the harder work of succession and cybersecurity. Five signals, each with a single "so what."

AI Concentration Without a Bubble

Oaktree's Howard Marks told Bloomberg on October 18 that it is "too early" to call AI stocks a bubble, arguing that a genuine bubble requires obliviousness — and the market is anything but oblivious. The S&P 500's Shiller price-to-earnings ratio sits near 41, just below the 1999 peak of 44, and Nvidia, Apple and Microsoft alone account for about 21% of the index; yet forward price-to-earnings multiples actually fell this year as earnings expectations strengthened. Ray Dalio and Michael Novogratz publicly disagree, and the Nasdaq 100 slid 5.5% in a single week after reaching a record high. So what: the risk is not broad overvaluation but concentration — a handful of names financing one another's AI build-out — which argues for diversifying equity exposure rather than exiting it.

China Taxes Offshore Trusts for the First Time

China's Ministry of Finance and State Taxation Administration jointly issued Announcement No. 21 (with No. 15) on July 24, imposing — for the first time — a consistent tax regime across the full lifecycle of offshore trusts with Chinese connections. Under the rules, a Chinese-resident settlor is taxed on trust income and gains regardless of whether distributions are made or whether the settlor is a beneficiary; "deeming" provisions identify the "real settlor" behind overseas nominees, and look-through rules prevent holding companies from blocking income. STEP Journal's Issue 5 examines the new requirement to report the trust's structure and asset holdings in detail. So what: China-connected structures drafted for privacy now face a documentation standard — review funding, control and reporting consistency before the next filing cycle.

Family Offices Rotate Back to Public Equities

Citi Wealth's 2026 Global Family Office Report — 351 offices across 41 countries — found 46% increased public-equity exposure over the year, making listed markets the top destination for new capital after years of rotation into private assets. Some 88% reported positive year-to-date performance and 41% still target 7–10% annual returns, while inflation (63%) overtook trade and tariffs (down from 60% to 18%) as the leading concern. So what: the shift is a liquidity recalibration, not a retreat — families want the flexibility to sell listed assets while staying selective in private markets.

Succession Turns Urgent as Cybersecurity Replaces Markets as the Top Worry

Roughly one-third of family offices expect a leadership transition in the family, office or business within five years — yet only 17% describe themselves as well prepared, Citi found, and half of RBC/Campden's North American sample report an incomplete or non-existent succession plan. RBC/Campden's 2026 report also shows cybersecurity jumping from 16% to 56% as the top near-term operational concern, even as two-factor-authentication adoption slipped from 92% to 83%. So what: continuity is now the binding constraint — a family that cannot answer who leads next, and who defends the balance sheet from breach, has a governance gap before it has an investment one.

Private Markets Head Toward $34 Trillion, Led by Evergreens

Preqin's Private Markets in 2031 forecast, released October 26, projects global private-markets assets under management exceeding $34 trillion by 2031, led by private equity at $11.6 trillion and private credit surpassing $5 trillion. Evergreen structures are expected to be the fastest-growing segment of private credit as the asset class expands beyond corporate lending into asset-based finance. So what: the evergreen convergence that Blackstone's BXPM and the Wellington–Vanguard–Blackstone alliance are retailing is now the industry's structural growth engine — expect more single-allocation products and, with them, more negotiating leverage for family capital.
