⚠ The Fiduciary Standard Cuts Both WaysHigh threat

The fiduciary obligation that makes a pension trustee reluctant to switch managers is the same obligation that makes them relentless about fees. A trustee who cannot easily justify changing provider can very easily justify demanding a lower price, and does, at every renewal.

That is the whole explanation for institutional index economics, and it applies to the $3.9 trillion of pension assets that are 62% of BlackRock's long-term institutional book¹. Duty of care produces stability on the asset side and permanent downward pressure on the revenue side, and the two are the same force.

There is a sharper version in defined contribution. Litigation over plan fees has become a standing feature of the American retirement system, and the reliable defensive posture for a plan sponsor is to select the cheapest available share class of a mainstream option. That dynamic has moved enormous sums into index funds and has driven the price of those funds toward zero, which has been good for BlackRock's assets and unhelpful for its revenue per dollar.

It also constrains the strategy. Putting private-market assets into defined contribution plans — the growth ambition — means persuading fiduciaries to accept higher fees, less liquidity and harder-to-verify valuations, in a legal environment that punishes exactly those three things. Regulatory permission is necessary and nowhere near sufficient.

Watch litigation and Department of Labor guidance rather than product launches. The product is straightforward to build; the fiduciary comfort to buy it is what does not exist yet.
