I was surprised, but not shocked, to see PostFinance announce that it will no longer impose fixed terms on its Ethereum staking product. After years of treating PoS assets like a locked‑in savings account, the Swiss bank is now allowing self‑initiated unstaking twice weekly, a flexibility that mirrors the cadence of traditional money‑market funds.
The change matters because it directly tackles one of the biggest friction points for institutional investors: liquidity. Until now, a 12‑month lock‑up meant that treasury managers had to allocate ETH with a long‑horizon view, often at the expense of balance‑sheet agility. By letting clients exit on a semi‑weekly basis, PostFinance turns staking into a truly tradable yield‑bearing instrument, comparable to a short‑duration bond.
From a market‑structure perspective, this could increase the on‑chain supply of ETH that is readily available for trading. More frequent unstaking means a larger, more fluid pool of liquid ETH entering exchanges, potentially smoothing price volatility and narrowing the premium‑discount gap that has plagued liquid staking tokens such as Lido’s stETH.
Speaking of Lido, the Swiss move forces a re‑evaluation of the dominant liquid‑staking model. Lido’s appeal has been its ability to provide instant liquidity, but it does so at the cost of a custodial layer and a built‑in fee. PostFinance’s offering, by contrast, keeps the underlying ETH under the bank’s custody while still granting near‑real‑time exit rights, which could be especially attractive to risk‑averse asset managers who value counterparty clarity.
Regulators will likely view this development through a dual lens. On one hand, the removal of lock‑ups aligns with Swiss banking standards that emphasize client autonomy and transparent risk disclosure. On the other, it raises questions about how frequent unstaking might affect network security if large validators suddenly withdraw large stakes. The bank’s decision to expand this model to other PoS chains will test the regulatory frameworks across jurisdictions.
Of course, flexibility introduces new risks. Rapid churn could pressure validator performance, and institutions may need robust monitoring tools to avoid inadvertent slashing events. Moreover, the ability to unstake twice a week could encourage speculative behavior, blurring the line between genuine yield‑seeking and short‑term trading.
Overall, PostFinance’s policy shift signals that staking is graduating from a niche, long‑term hobby to a mainstream, liquid asset class. If other custodians follow suit, we could see a wave of institutional capital treating PoS tokens with the same liquidity expectations we have for Treasury bills, fundamentally reshaping crypto’s market structure.
