Coco bonds are a type of debt security that allows companies to raise funds by issuing bonds to investors.
Coco bonds are often used by companies to refinance existing debt or to raise capital for expansion. They can be issued with a fixed interest rate or a floating rate tied to a benchmark like LIBOR.
The key benefit of coco bonds is that they are senior to other types of debt, such as subordinated debt, which means they are repaid first in the event of a company's default.
Investors in coco bonds can earn a fixed return, typically in the form of interest payments.
What Are?
Contingent Convertible Bonds, also known as CoCos, are a type of hybrid financial instrument.
CoCos are primarily issued by European financial institutions and are designed to help shore up a bank's balance sheets by allowing it to convert its debt to stock if specific, unfavorable capital conditions arise.

These bonds have a specific strike price that, once breached, allows the conversion of the bond into equity or stock.
CoCos can be converted into stocks or equity of the issuing company if the strike price is breached, and they combine elements of both debt and equity securities.
They have a unique feature where they automatically convert into equity if specific predefined triggers are breached, like the entity's capital ratio falling below a certain threshold.
The bonds offer higher yields as they carry high risk, and their value may be highly volatile due to market uncertainty.
Here are some key characteristics of CoCos:
- CoCos are financial instruments that may convert into the issuing company's equity or stocks if the pre-established strike price is breached.
- The bond's conversion feature is contingent on the institution facing economic turmoil.
- These bonds assist the institutions in meeting regulatory capital requirements.
CoCos are also referred to as AT1 bonds, and they have a perpetual nature, meaning they do not have a maturity date.
The contingent events that lead to a conversion to equity shares are called 'trigger events', which refer to the point at which these CoCo bonds have to start absorbing losses.
CoCos are primarily issued by banks, but are also issued by insurance companies and non-bank financial institutions.
Key Features and Benefits

CoCo bonds have a unique feature that sets them apart from traditional bonds. The bond can be converted into stock at a predetermined strike price.
CoCo bonds are used by banks to absorb losses automatically and meet regulatory capital requirements. They're a type of security that's designed to help banks stay afloat during financial difficulties.
Investors in CoCo bonds receive interest payments that are typically much higher than those from traditional bonds. This is because CoCo bonds are riskier, and investors are taking on more risk by investing in them.
There are three potential results for investors if the issuer's capital drops below a specific level: the CoCo being converted to common shares, a temporary write-down of the CoCo's value, or a permanent write-down of the CoCo's value.
Here are the three potential results for investors:
CoCo bonds can be triggered by a variety of events, including the price of the underlying shares, the bank's need to meet regulatory capital requirements, or the demand of a managerial or supervisory authority.
The conversion of CoCos into equity can dilute the ownership stakes of existing shareholders, which may impact share prices and the distribution of ownership within the issuing institution.
How Coco Bonds Work
Coco bonds are a type of debt security that offers investors a unique combination of fixed interest payments and the potential for capital appreciation through conversion to common stock. They are similar to convertible bonds, but with modified terms for conversion.
CoCo bonds provide investors with specified interest payments that are fixed over the course of the bond's life. This means that investors can expect a steady income stream, just like with traditional bonds.
CoCo bonds contain triggers that outline when the conversion of debt holdings to common stock is a possibility. These triggers can be based on book values or market values, and can include factors such as the bank's CET1 ratio or its market capitalization to assets ratio.
Here are some examples of triggers that can be used in CoCo bonds:
- Instances of underlying shares of the institution reaching a certain level
- The need to meet regulatory capital requirements by the bank
- Instances of managerial or supervisory authority being demanded
These triggers can be used to determine when the bond is converted to equity, allowing the bank to boost its equity and absorb losses.
Understanding

CoCo bonds are a type of debt security that offers investors a unique combination of fixed interest payments and the potential for capital appreciation through conversion to common stock.
They are essentially a modified version of convertible bonds, with terms that allow for conversion to common stock under certain conditions.
CoCo bonds are subordinated, meaning they rank junior to all other debt and are senior only to ordinary stock and convertible debt.
The conversion of CoCo bonds to common stock is triggered by specific events, such as the bank's underlying shares reaching a certain level or the need to meet regulatory capital requirements.
There are two types of triggers: mechanical and discretionary, although some CoCos may include both.
Book value triggers are set based on the bank's Common Equity Tier 1 (CET1) capital as a ratio of risk-weighted assets (RWA), while market value triggers are set based on the bank's market capitalization to assets.

Here are the key differences between book value and market value triggers:
- Book value triggers are subject to balance sheet manipulation and may not reflect the bank's true financial health.
- Market value triggers are more difficult to price and may create incentives for stock price manipulation.
CoCo bonds can also be redeemed by the issuer, although this is not guaranteed and may depend on market conditions.
In some cases, the issuer may choose not to call the bonds, leaving investors to receive only coupon payments indefinitely.
In the case of HSBC's USD 4.7% Perp, the bond can be called back beginning 9 March 2031, but if not called, the coupon gets reset at the prevailing 5Y US Treasury yield + 325bp.
Dividend Stopper/Dividend Pusher
A dividend stopper is a common feature in perpetual bonds, including CoCos, that requires the issuer to not pay a dividend if it decides to stop coupon payments.
Dividend stoppers are beneficial to CoCo bondholders as they restrict the issuer from paying dividends on its equity in times when it hasn't paid coupon to its CoCo bondholders. This is seen in BOCOM's 3.8% Perp, which had a dividend stopper attached to it.
On the other hand, dividend pushers are a covenant seen in perpetual bonds issued by both banks and corporates that require the issuer to make a coupon payment if it has paid a dividend on its shares.
Risks

Investing in CoCos comes with its own set of risks. One major downside is that the share price will be diluted, further reducing the earnings per share ratio.
Regulators often require banks to be well-capitalized, making it difficult for investors to sell or unwind a CoCo position. This can be a major concern for those looking to exit their investment.
Investors bear the risks and have little control if the bonds are converted to stock. This lack of control can be unsettling, especially if the conversion occurs at an inopportune time.
CoCos are known for their complexity, primarily due to the contingent conversion mechanism and varying trigger conditions. Understanding these terms and risks can be challenging, making them less suitable for novice investors.
The value of CoCos is closely associated with the issuing institution's financial status. If the issuer faces financial difficulties, the likelihood of CoCo conversion increases, leading to significant losses for investors.
Here are some key risks associated with CoCos:
- Share price dilution
- Difficulty selling or unwinding a CoCo position
- Lack of control over conversion to stock
- Complexity of contingent conversion mechanism
- Vulnerability to issuer financial difficulties
Examples of a

Contingent convertibles, or CoCos, are a type of bond that can automatically convert to equity if a bank's capital ratio falls below a certain level. This can happen when a bank experiences financial difficulties.
Let's look at some examples of CoCos in action. Deutsche Bank issued CoCos with a trigger set to core Tier 1 capital, which means that if Tier 1 capital falls below 5%, the convertibles automatically convert to equity.
If you own a CoCo with a $1,000 face value that pays 8% per year in interest, you'll receive $80 per year. This can be a good investment, but it's essential to understand the risks involved.
The conversion ratio is crucial in CoCos. In one example, an investor received 25 shares of the bank's stock for a $1,000 investment in the CoCo. However, if the stock price declines, the investor may experience significant losses.
Here are some key differences between CoCos and other types of securities:
- Convertible Securities
- Yankee Bonds
- Fidelity Bonds
It's also worth noting that the bank's stock price can be volatile when a CoCo trigger occurs. In another example, Jake's CoCo converted into shares of the bank's stock when the capital ratio dropped below the trigger level. The bank's stock price was $20 per share at the time of conversion.
Regulation and Financial Crisis
The failure of Credit Suisse in 2021 highlighted the challenges of CoCos in preserving financial stability during crises.
Regulators have refined the rules related to CoCos to strike a balance between reinforcing banks' capital positions and preventing financial instability.
CoCos are regulated in the European Union under the Basel III framework, which sets minimum standards for the banking industry.
Credit Suisse Failure
The Credit Suisse Failure was a significant event in the banking sector, highlighting the challenges of Contingent Convertible Securities, or CoCos. In 2023, Credit Suisse Group AG's CoCos suffered a historic $17 billion loss after UBS Group AG agreed to buy the bank.
This loss was triggered by a total write-down of CoCos, which was a deliberate decision to contain a spreading crisis of confidence in global financial markets. The Swiss government brokered the deal to prevent a larger financial meltdown.
The Credit Suisse case raised concerns about the future of the CoCo market and AT1 bonds. European regulators reiterated that equities should absorb losses before bondholders, but the decision to write down the bank's riskiest debt sparked a furious response from some creditors.
Credit Suisse had 13 CoCo issues outstanding worth a combined 16 billion Swiss francs. This was a significant amount, but it was also a known risk when banks issue CoCos.
The failure of Credit Suisse in 2023 was not an isolated incident. In 2021, the bank had also encountered financial difficulties, which highlighted the challenges of CoCos in preserving financial stability during crises.
Are Regulated?
Regulation plays a crucial role in preventing financial crises. In the European Union, contingent convertibles (CoCos) are regulated under the Basel III framework, which sets minimum standards for the banking industry to improve supervision and risk management.
The Basel III framework requires banks to maintain a minimum level of capital to ensure their stability and resilience. This is achieved through stricter capital requirements, which help prevent banks from taking on too much risk.
Regulatory frameworks like Basel III are essential in preventing financial crises, as they provide a safety net for the banking industry. By setting clear standards, regulators can help prevent the kind of reckless behavior that led to the 2008 financial crisis.
In the EU, regulatory bodies have implemented measures to strengthen bank supervision, including regular stress tests and closer monitoring of bank activities.
What Happens During a Financial Crisis?
During a financial crisis, the value of Contingent Convertibles, or CoCos, can significantly decrease due to their high-risk nature. This can put investors at risk for losses.
If a bank is struggling and needs additional capital, it may postpone the payment of interest or convert the bond into equity at a lower price to meet regulatory standards.
In dire situations, a bank may write down the value of CoCos to zero.
History and Comparison
CoCos and convertible bonds share a similar trigger point that converts the bond into equity or stock, but CoCos have multiple triggers. They also pay higher interest rates than convertible bonds due to their risks.
CoCos have special options that help banks absorb a capital loss, a feature that's not typically found in convertible bonds. This is one reason why CoCos are used mainly by banks to improve their financial position.
CoCos are secondary debts issued by banks, and they have a lower priority than convertible bondholders in the event of a business default.
Background of

Contingent convertibles, also known as CoCos, were introduced to help financial institutions meet the stricter capital requirements of Basel III.
Basel III is a regulatory accord that aimed to improve the supervision and risk management of the banking industry.
The accord set a new standard for the banking industry, requiring financial institutions to hold more capital to reduce the risk of another financial crisis.
CoCos were designed to be a flexible solution for financial institutions to meet these new capital requirements.
Their popularity grew as a result of Basel III, which was implemented in 2013 to improve the regulatory framework for the banking industry.
Comparison
CoCos and regular convertible bonds have some key differences. CoCos are designed as loss-absorbing instruments that can convert into shares when a bank is under capital distress.
Banks use CoCos differently than corporations use convertible bonds. CoCos have their own set of parameters that warrant the bond's conversion to stock, whereas convertible bonds are based solely on stock price appreciation.

CoCos pay higher interest rates than convertible bonds due to their risks. This is because CoCos have special options that help banks absorb a capital loss.
CoCos are secondary debts issued by banks, whereas convertible bonds are issued by companies to raise capital. CoCos are used mainly by banks to improve their financial position.
Regular convertible bonds generally come with low coupons as they are a cost-effective way to raise funds. In contrast, CoCos have higher interest rates to reflect their risks.
The stock price might be lower than desired when a CoCo conversion is triggered, putting investors at risk for losses. This is because the bank's shares may be declining in value during times of financial stress.
CoCos and AT1 bonds are often used interchangeably, as they pertain mainly to banks and serve a similar purpose.
Conclusion and Meaning
CoCo bonds are high-yield, high-risk products that are popularly used tools in European investing, also known as enhanced capital notes (ECN). They serve as hybrid debt securities that bring with them specialized options that provide the financial institution responsible for issuing them with cushioning to help absorb a capital loss.
Individual investors, particularly from Europe and Asia, along with private banks, are the primary investors of these bonds. European financial institutions are the primary issuers of CoCo bonds.
