Morgan Stanley Weighs Staking Routes as New ETH, SOL Trusts Land

Morgan Stanley has laid out how financial advisors should evaluate crypto staking across three venues, laying the groundwork just as its two staking-enabled trusts reach clients. In an internal newsletter aimed at advisors, John Keller of Morgan Stanley Investment Management compared staking through an exchange-traded product, a centralized exchange, or a self-custody wallet — and argued the venue determines how much of the staking reward an investor actually keeps.

The comparison is not academic. On July 28, 2026, the firm launched the Morgan Stanley Ethereum Trust (MSSE) and the Morgan Stanley Solana Trust (MSOL), both staking-enabled ETPs. Together they extend a crypto product lineup that, per the research findings cited by the firm, holds more than $14 billion in assets under management.

What are the terms on the new trusts?

The numbers are concrete. MSSE is designed to stake between 50% and 80% of its ETH holdings; MSOL can stake up to 100% of its SOL. Both trusts pass approximately 95% of gross staking rewards to shareholders after provider fees, and each carries a sponsor fee of 0.14%. Morgan Stanley retains none of the staking income for itself, per the same findings.

The partial-staking band on the Ethereum trust reflects an operational tradeoff rather than caution for its own sake. Staked ether can take time to unlock, while a fund has to manage redemptions. Keeping a slice unstaked gives the trust liquidity headroom. The Solana trust's 100% ceiling signals a different design choice for that network.

Why does the venue matter?

Staking means locking a proof-of-stake token — Ethereum's ether is the canonical example — to help secure the network in exchange for rewards. Keller's framework treats ownership structure as the deciding variable, with each route carrying different implications for liquidity, reward share, and exposure to validator slashing.

Slashing is the risk that makes advisors nervous. A validator runs the machinery behind staking; if it breaks network rules or malfunctions, the protocol can penalize the funds staked through it. The newsletter's "Ask an Expert" segment put that risk front and center. Waseem Salim, CEO of staking firm Valdora, laid out the due diligence practices that can shield clients from validator penalties.

The practical calculus looks like this:

• Self-custody: the investor safeguards private keys and picks validators personally — maximum control, maximum operational burden.
• Centralized exchange: the third party handles the mechanics, but assets sit on a platform the investor does not control.
• ETP: the activity is wrapped in a familiar brokerage format, the same one clients already use for stocks and bond funds.

The ETP pitch is straightforward: advisors get staking exposure for clients without the clients holding tokens or running the plumbing. But the wrapper does not eliminate what sits beneath it. In an ETP, investors rely on the fund's selection of staking providers rather than their own, and slashing, liquidity constraints and network-level issues still exist underneath the ticker symbol. Salim's due-diligence emphasis is a reminder that convenience and understanding are not the same thing.

What should advisors watch now?

The benchmark to track is the gap between gross and net rewards. A roughly 95% pass-through combined with a 0.14% sponsor fee gives advisors a concrete yardstick against exchange staking programs and self-custody yields — and as MSSE and MSOL build operating history, realized reward distributions versus those targets will show whether the wrapper earns its keep.
