An external review says Fed supervisors “knew, or should have known” Silicon Valley Bank’s vulnerabilities; Bowman released the findings as policymakers raised rates this week for the first time since 2023.
An external review by Starling Advisory Group concluded Federal Reserve staff “knew, or should have known” Silicon Valley Bank’s vulnerabilities, Vice Chair for Supervision Michelle Bowman said, releasing findings the same week the Fed voted to raise rates for the first time since 2023.
Starling Advisory Group’s Findings
Bowman said the outside review portrays a supervisory gap: examiners “knew, or should have known” the bank’s vulnerability before it crystallized. She underscored a funding profile the review calls out — deposits that were “94 percent uninsured and concentrated in venture capital–backed technology companies.” That composition hardwires run propensity into a bank’s liabilities when asset valuations fall or when risk‑signaling events materialize. In publishing the findings, Bowman placed the supervisory lens on structural fragilities that are legible ex ante, not only post‑mortem: concentration, insurability, and interest‑rate sensitivity. The review, announced in a speech in London, reframes oversight not as reaction to a single failure but as a call to recalibrate how supervisors weigh funding structures against market‑rate shocks.
Bowman’s remarks also connect asset and liability channels: Silicon Valley Bank had sold securities at a $1.8 billion loss, and large holdings of U.S. Treasuries had lost value after the Fed began raising interest rates. The review’s emphasis on a 94 percent uninsured, clustered depositor base explains why signaling around capital and asset sales would propagate quickly through that network. These are balance‑sheet mechanics, not idiosyncrasies: when long‑duration securities reprice lower amid tightening, and the funding stack lacks insurance backstops or diversification, the path from valuation shock to liquidity pressure compresses dramatically.
Risk Mechanics in Uninsured Bases
The first‑order effect is straightforward: uninsured, concentrated deposits impose a higher bar for supervisory early‑warning systems. They shorten the feedback loop between adverse marks on securities and withdrawals, and they amplify the signaling power of capital‑raising disclosures. In such structures, supervisors need to calibrate expectations around interest‑rate risk management, liquidity buffers, and disclosure timing to the speed of the underlying depositor network. Bowman’s public remarks did not quantify account granularity or duration profiles, leaving open how concentration thresholds should map to heightened supervisory baselines. That omission matters because different clusters — even within venture capital–backed technology companies — can propagate stress at different speeds depending on funding interlinkages.
The second‑order effect is interaction with policy rates. The report was released the same week the Fed voted to raise interest rates for the first time since 2023, which ties supervisory signaling to a macro lever that directly reprices securities and, indirectly, depositor behavior. That coincidence suggests supervisors may be embedding rate‑path sensitivity into expectations for how banks manage unrealized losses and communicate capital plans. The analytical point: when macro policy tightens, the liquidity cost of mis‑timed disclosures grows in uninsured, concentrated bases, raising the premium on pre‑emptive capital buffers and cleaner interest‑rate hedging narratives.
$1.8 Billion Loss Context
- Monitor whether Bowman articulates supervisory expectations for interest‑rate risk in securities portfolios and related disclosures.
- Track Fed communications that reference uninsured, concentrated depositor bases in technology‑focused institutions.
- Listen for references to venture capital funding cycles within supervisory speeches and examination priorities.
- Watch for coordination signals between the Fed and the FDIC on rapid‑resolution playbooks for concentrated depositor networks.
Fed Rate Hike This Week
Two near‑term catalysts elevate this from a backward‑looking report to a forward supervisory template. First, Bowman announced the review in London while emphasizing funding concentration and insurability — a public cue on where supervision will focus next. Second, the release coincided with the Fed voting to raise interest rates for the first time since 2023, linking oversight rhetoric to the policy variable that reprices securities and tests funding stability. The personnel backdrop also matters: Michael Barr’s prior review in 2023 described overcaution; Bowman now holds the supervisory portfolio after his February 2025 departure and Senate confirmation. The results of the new review are likely to prompt new questions about how concentration, uninsured deposits, and interest‑rate exposure will be embedded into supervisory expectations and board‑level risk governance.

🧠 HafidWatch Take
If concrete evidence emerged that supervisory teams not only identified SVB’s vulnerabilities but also fully implemented and enforced remediation plans with timely board validations, then the prevailing narrative attributing failure to examiners’ “knew or should have known” negligence would be fundamentally flawed. This would indicate the issue is not one of detection but a failure of escalation or decision-making at higher supervisory levels, thereby challenging the core framing of supervisory breakdown as frontline oversight failure.
Historically, the regulatory response to the 2008 collapse of Washington Mutual reveals a similar dynamic where frontline concerns were flagged, but resolution faltered due to governance and escalation lapses above examiners. This precedent suggests that attributing failures to examiners alone risks oversimplifying complex supervisory hierarchies. Additionally, the market’s immediate anticipation of tougher supervision may be misaligned by conflating this review with the Fed’s concurrent rate hike, overlooking how these tools serve distinct but interacting roles rather than a single corrective mechanism.
