Santander raises $1.5B in convertible bonds
What's the deal? Santander has issued $1.5 billion in convertible bonds that can be exchanged into shares. The perpetual bonds qualify as additional Tier 1 (AT1) capital — a key layer of a bank's financial safety net — and may be converted at the issuer's discretion.
Why now? Banks across Europe have been shoring up their capital buffers amid tighter regulatory requirements and economic uncertainty. AT1 instruments let lenders strengthen their balance sheets without immediately diluting existing shareholders, making them an attractive tool in the current environment.
What could go wrong? AT1 bonds sit at the riskiest end of a bank's capital structure. If Santander's financial health deteriorates, bondholders could face forced conversion into equity or even a write-down — as Credit Suisse AT1 holders learned in 2023. For existing shareholders, conversion would dilute their stakes.
The signal: Santander's $1.5 billion AT1 issuance comes as the mature banking group continues to leverage its scale to access capital markets on favourable terms. With European banks under sustained pressure to bolster regulatory buffers, the deal underscores how established lenders can tap investor demand for higher-yielding instruments — even two years after the Credit Suisse AT1 wipeout rattled the asset class.
