Global AT1 bond issuances have hit a notable rough patch since 2025 due to higher interest rates and a more cautious approach to risk from institutional investors. As borrowing costs rise, banking groups are slowing down new offerings, which could lead to tighter commercial credit conditions worldwide.
LONDON — The global financial market for Additional Tier 1 (AT1) bond issuances has entered a prolonged contraction phase, with volume tracking downward significantly since the opening of 2025. Institutional banking groups are scaling back new capital offerings as investors demand steeper yields to absorb the risks associated with these contingent convertible instruments.
The structural slowdown marks a definitive shift in institutional bank capitalization strategies, directly impacting corporate borrowing costs, tier-1 equity buffers, and fixed-income portfolio allocations for major asset managers globally.
Macroeconomic Headwinds and Yield Spreads Dent Issuance Volumes
According to debt capital market data compiled by the Bank for International Settlements (BIS), global AT1 bond issuances have faced structural roadblocks following coordinated central bank monetary policy updates. The persistent higher-for-longer interest rate environment initiated by the Federal Reserve and the European Central Bank has narrowed the historical yield spreads that previously made hybrid debt highly attractive to institutional buyers.
As benchmark government yields remain elevated, sovereign wealth funds and pension managers are rotating capital into safer, high-quality debt instruments. This repositioning has forced banking syndicates to price new AT1 bond issuances at much higher coupons to satisfy risk premiums, making the cost of maintaining regulatory capital buffers unsustainably expensive for mid-tier lenders.
Technical Risk Valuation and Pricing Volatility
The current downturn in AT1 bond issuances reflects a long-term recalibration of risk models that began in earnest during the preceding multi-year cycle. Debt desks indicate that the complete write-down of Credit Suisse's AT1 portfolio during its state-backed rescue established a lasting legal and structural precedent that continues to influence debt market pricing.
Global credit rating agencies emphasize that institutional investors are no longer evaluating these hybrid notes merely as high-yield extensions of preferred equity. Instead, buy-side analysts are pricing in the legal reality of permanent principal write-downs and coupon cancellation clauses. This meticulous approach to technical risk valuation has resulted in several tier-2 and tier-1 corporate banking entities postponing their scheduled refinancing cycles altogether.
Repercussions for Commercial Banks and Corporate Lending
The ongoing rough patch in AT1 bond issuances has clear operational consequences for commercial banking operations and corporate clients worldwide. Under Basel III banking framework rules, lenders must maintain strict capital adequacy ratios to protect against unexpected economic shocks. When the primary channel for raising flexible AT1 capital constricts, institutions are forced to consider less efficient capital preservation methods.
To maintain required regulatory reserves, some commercial banking groups are limiting credit expansion to middle-market corporate borrowers and restricting secondary corporate loans. Additionally, if existing AT1 bond issuances reach their scheduled optional call dates and banks choose to extend rather than redeem them due to high refinancing costs, the decision can trigger negative market sentiment, raising the bank's overall cost of capital.

"According to officials analyzing international debt structures, the structural mechanics of hybrid bank capitalization are undergoing a long-term repricing phase," stated senior fixed-income research directors at global banking compliance groups. "The steady reduction in new AT1 bond issuances since 2025 highlights a more cautious approach to risk management, where institutional investors require legally ironclad structural protections before committing large-scale capital to bank debt instruments."
Why It Matters
For fixed-income investors, treasury managers, wealth advisors, and corporate clients, tracking the health of AT1 bond issuances provides a vital indicator of overall banking sector stability. A healthy, liquid market for hybrid debt allows banks to lower their capital costs and expand business credit lines. Conversely, a restricted issuance market can tighten credit terms, increase lending fees, and pressure banks to optimize earnings through more conservative asset management rather than proactive commercial growth.
Key Facts at a Glance
Issuance Decline: Volume metrics for global AT1 bond issuances have experienced a clear downward trend since early 2025.
Elevated Yield Spreads: Banks are facing significantly higher coupon demands from institutional buyers to clear new capital offerings.
Risk Model Shifting: Modern credit assessments are pricing in permanent write-down and coupon-skipping clauses with greater scrutiny.
Refinancing Delays: Multiple mid-tier international banking organizations have chosen to postpone scheduled call options to avoid high replacement costs.
Lending Restraints: Tightening regulatory capital markets can lead to conservative commercial lending practices to preserve underlying balance sheet ratios.
Frequently Asked Questions
What exactly are AT1 bonds and why do banks issue them?
Additional Tier 1 (AT1) bonds are hybrid capital instruments created under Basel III rules to absorb financial shocks. They function as debt during normal periods but can convert into equity or be written down permanently if a bank's capital levels fall below a specific regulatory threshold.
Why did the market for AT1 bond issuances shift downward after 2025?
The downturn is primarily driven by higher benchmark interest rates worldwide, which make standard lower-risk bonds more competitive. This shift, combined with heightened risk awareness regarding write-down clauses, has driven up the borrowing costs for banks issuing hybrid notes.
What happens if a bank decides not to call an AT1 bond on its scheduled date?
If a bank chooses not to redeem an AT1 bond at its optional call date, the bond resets its coupon rate according to a pre-determined spread over benchmark rates and continues to run. While legally permitted, choosing not to call can signal high refinancing stress to the broader market, potentially lowering the bank's overall credit standing.
