Convertible notes represent loans that startups owe investors

In the second part of a two-part series, convertible notes are explained to be a tool angel investors use to ensure they see a return on their investment in a startup.

Since the 1990s, banks have sold some of the credit risk of their accounts to external investors, known as SRTs, or synthetic risk transfers

This means if the account defaults, the outside investors assume most of the risk in return for some regular payments, freeing up the bank's ledger. It is a form of insurance used by banks to allow them to free up capital. In 2024, nearly $100B worth of SRT notes were sold.

To continue selling mortgages, agencies that determine how risky a loan is gave high ratings to homebuyers regardless of their actual risk portfolio.

In 2024, 74% of homebuyers took out a mortgage

Debt owed on mortgages made up about 70% of US consumer debt as of 2025. Mortgage collateral ensures the lender isn’t at a complete loss if the borrower defaults. Under most mortgage contracts, the property is considered collateral under the loan. This means that if a borrower doesn’t repay the loan, then the lender can seize their property.

Securitization has become common practice in home financing

When a homebuyer finances with a lender, they aren’t necessarily the one footing the bill. After a buyer secures a home loan, the lender can sell the loan to another financial institution or a private institution. That group can later sell that mortgage to investors. This is called securitization.

In 2008, the 'Big Short' mastermind Michael Burry made more than $700M.

Direct lending typically involves 'senior loans'

Direct lending, the most common subtype of private credit, typically involves senior loans which are secured by a company's assets. "Junior capital," on the other hand, is a type of private credit that is not secured by a company's assets, making it generally riskier than direct lending.

Direct lending is the most common form of private credit

Other types include opportunistic credit, special-situations credit, mezzanine finance, venture debt, infrastructure debt, real estate debt, and more. All of these sources of capital technically create private transactions, so they can all call themselves private credit.

Investors need a 'margin account' to short sell stock

Margin accounts are leveraged accounts through brokerage firms that allow investors to make trades without the full amount of capital on hand. Similar to a secured loan, margin accounts often require some form of collateral and typically have a cap on how much investors can borrow. However, trading with a margin account is much riskier than a traditional investment account. Fees and charged interest are due on margin accounts, regardless of trade performance, meaning it's possible for investors to lose more money than just their initial investment.

These bonds offer investors regular interest payments in addition to the return of the principal amount at maturity. They allow companies to raise capital without losing ownership.

The bond market is where bonds and other debt securities are traded

Bonds are fixed-income investments allowing individuals to lend a specific amount of money to a large entity, like a government or corporation, for a set amount of time in return for interest paid out over the life of the loan. The bond market is widely considered a key economic barometer.

The term 'securities' refers to different types of investments, such as stocks or bonds.

Different CDs can have different term lengths, interest rates, and more

For instance, if a bank needs more deposits to fund loans, then it may offer high interest rates to attract deposits. Alternatively, a large bank with sufficient deposit reserves may have less incentive to grow its CD portfolio, offering lower rates as a result.

Borrowers were increasingly defaulting on private credit loans as of early 2026
