Three of Wall Street's most prominent institutions issued preferred shares last week at valuations that seasoned investors have not seen since before the collapse of Lehman Brothers. BNY Mellon priced a $500 million Series N preferred stock offering on 22 July with a reset spread of 186.8 basis points, setting a new post-financial crisis low for the market. Goldman Sachs and Citizens Financial followed within two days, each pricing their own preferred stock at similarly unprecedented levels, Bloomberg reported.
Preferred shares are hybrid securities, sitting somewhere between a bond and a stock. Banks issue them because they count toward Additional Tier 1 capital, or AT1, a regulatory buffer designed to absorb losses and protect depositors before shareholders bear the brunt. The "reset spread" is the premium above a benchmark interest rate that investors demand in exchange for holding these instruments. The tighter that spread, the less compensation investors are receiving for the risk.
Why are spreads this tight?
The proximate cause is a wall of investor demand chasing yield in a market where US banks look stronger than they have in years. Large American lenders posted record earnings in the first quarter of 2026, with five of the six biggest beating consensus forecasts. America's largest banks returned more than $110 billion to shareholders in 2025, and buybacks accelerated further into early 2026. That financial strength, combined with a relatively calm credit environment, has made bank-issued paper look attractive to institutional investors hunting for income.
The regulatory backdrop is also reshaping investor thinking. In March 2026, US federal banking agencies issued sweeping proposals to revise the Basel III capital framework, marking what Deloitte described as "the most significant reset to the regime in more than a decade." Overall, bank capital requirements are expected to decrease across the industry under the proposals, through lower minimum risk weights and reduced capital surcharges. If that deregulatory shift is priced into investor expectations, it may partly explain their willingness to accept thinner spreads.

A cautionary tale investors may be forgetting
The episode draws uncomfortable comparisons with the Credit Suisse collapse of March 2023, when Swiss regulator FINMA ordered the complete write-down of CHF 16 billion in AT1 bonds as part of the emergency takeover by UBS. The wipeout was particularly shocking because equity holders received some residual value while AT1 bondholders were left with nothing, inverting the traditional creditor hierarchy. Investors who held those instruments were reminded, at enormous cost, that AT1 instruments are explicitly engineered to absorb losses in a crisis.
“"There is unfortunately no such thing as 100% security, as the example of the circumvention of traditionally respected capital hierarchies shows." — LGT analysis, April 2024”
Some analysts have questioned whether the current enthusiasm fully reflects those risks. US preferred shares differ structurally from European AT1 bonds, and European and UK regulators were quick to distance themselves from FINMA's approach after the Credit Suisse rescue. Nevertheless, the core vulnerability remains: buyers accepting a reset spread of under 190 basis points are receiving historically low compensation for holding instruments that, by design, are the first to absorb losses when a bank encounters serious difficulty. Whether benign conditions persist long enough to justify that price is the central question the market is now answering with remarkable confidence.
