Credit Suisse recently suffered a significant loss due to the default of one of its prime brokerage clients. The impact of this event has been felt across the $275 billion market, and Credit Suisse and other market participants are taking steps to address the situation.

The loss for Credit Suisse has been historic, with around $17.3 billion worth of risky bonds wiped out after a takeover by UBS. This loss triggered a “complete write-down” of Credit Suisse’s additional tier 1 (AT1) bonds to increase core capital, while the bank’s shareholders are set to receive 3 billion Swiss francs. The bond write-down is the most significant loss yet for Europe’s AT1 market. It far eclipses the only other write-down of this type of security: a €1.35 billion loss suffered by junior bondholders of Spanish lender Banco Popular SA in 2017.

AT1 bonds were created in Europe during the global financial crisis to act as shock absorbers when banks begin to collapse. If a bank’s capital ratios fall below a predefined level, they are supposed to result in irreversible losses to bondholders or be converted into equity, thus supporting the bank’s balance sheet and enabling it to continue operating. However, these bonds are risky, and Credit Suisse’s losses highlight the risks of investing in such bonds.

Credit Suisse’s bond issuance practices are worth noting in the context of this loss. The bank issued different types of bonds, including traditional and hybrid bonds, such as AT1. Traditional bonds are issued to finance the bank’s operations and pay a fixed interest rate to investors. Hybrid bonds, such as AT1 bonds, have more complex structures and offer higher yields but come with higher risks. Credit Suisse’s losses and the write-down of these risky bonds could affect the broader financial market.

The risks involved in investing in risky bonds, such as those issued by Credit Suisse, include the risk of default, credit risk, liquidity risk, and market risk. These bonds may offer higher yields, but investors must be aware of the potential risks involved. Investors who hold these bonds effectively provide capital to the issuer and should be aware of the issuer’s financial health and business operations.

In response, Credit Suisse and other market participants are taking steps to address the risks associated with such bonds. Credit Suisse plans to cut its exposure to risky assets and increase its capital buffers to ensure it meets regulatory requirements. Other market participants are also taking similar steps, and regulators are increasing their oversight of these bonds to prevent such losses from happening again.

In conclusion, Credit Suisse’s loss due to the default of its prime brokerage client highlights the risks involved in investing in risky bonds, such as AT1 bonds. The loss has wiped out around $17.3 billion worth of risky bonds, and the broader market for these bonds has tumbled in the past two weeks. Credit Suisse and other market participants are taking steps to address the situation, including cutting exposure to risky assets, increasing capital buffers, and increasing regulatory oversight of these bonds. The event serves as a reminder to investors that high yields come with higher risks and the importance of understanding the risks associated with their investments.
