The 60-Second Version

If you have spent any time looking at income-producing assets in the past two years, you have probably seen BDCs show up in screeners next to REITs and closed-end bond funds. The SEC published an investor bulletin on publicly traded BDCs that lays out the regulatory basics, and I recommend reading it before you buy a single share. What that bulletin does not tell you is how to distinguish a BDC with durable income from one that is quietly building a watch-list problem. That is what this guide covers.

The private credit market now exceeds $2 trillion globally, surpassing the U.S. high-yield bond market. Institutional investors have accessed this market for years through private debt funds requiring $5 million minimums and long lockup periods. BDCs give accredited investors a liquid, publicly traded route into the same asset class, with yields currently running 10-12.1% at the largest names.

That combination of income and accessibility sounds compelling. It is, with conditions attached.

What a BDC Actually Is

Congress created the BDC structure in 1980 as an amendment to the Investment Company Act of 1940. The original intent was to channel capital from public markets into small and mid-sized businesses that could not access public debt markets. The structure has worked. BDCs collectively manage hundreds of billions in assets today, and the largest single vehicle, Ares Capital Corporation (ARCC), reported $28.3 billion in total assets and $3.052 billion in investment income for fiscal year 2024.

Here is the plain-English version of how the structure works. A BDC raises equity capital through a public offering, lists on an exchange, and then borrows additional money against that equity base. It deploys the combined capital as loans or equity investments into companies that private equity sponsors or management teams are growing or acquiring. Those companies pay interest. The BDC collects interest, pays its operating costs and borrowing costs, and distributes at least 90% of net taxable income to shareholders as dividends. That distribution requirement is what drives the high yields. The BDC cannot hoard earnings the way an industrial company can.

For tax treatment, BDCs elect regulated investment company (RIC) status, similar to how REITs pass income through to shareholders. If the BDC hits the 90% distribution threshold, it pays no corporate income tax on the distributed portion. You pay ordinary income tax on dividends received unless held in a tax-advantaged account.

The 2018 Small Business Credit Availability Act doubled the allowable leverage limit from 1:1 to 2:1 debt-to-equity. Most well-managed BDCs operate below the legal maximum, but the higher ceiling means the structure can amplify returns in a benign credit cycle and amplify losses when credit deteriorates.

How BDCs Make Money

The primary revenue engine is interest income from floating-rate senior secured loans. Most BDC portfolios run 85-96% floating rate, priced at a spread above SOFR. At current credit spreads of 500-700 basis points on top of prevailing SOFR rates, the gross yields on new originations are substantial. Blue Owl Capital Corporation (OBDC) reported 96.3% floating-rate exposure in its Q3 2024 portfolio. FS KKR Capital (FSK) ran an 8.8% weighted average yield on its debt portfolio as of Q1 2026.

Secondary revenue comes from origination fees, amendment fees, and equity co-investments alongside sponsor-backed transactions. When a BDC has a relationship with a large private equity firm, it often participates in multiple deals within that sponsor's portfolio, which generates fee income that does not depend on credit performance.

A third revenue line is payment-in-kind income, or PIK. PIK is interest that a borrower pays by issuing additional debt rather than cash. The BDC accrues PIK as income, which flows through the income statement and technically qualifies as distributable income. But no cash has changed hands. By mid-2024, PIK income represented roughly 11-12% of loan holdings by value across the sector, down from a 13%-plus peak. I will come back to why this matters when I walk through the risk factors.

The Yield Numbers

The three largest publicly traded BDCs currently yield the following on a trailing basis. These numbers shift with share price and dividend declarations, so verify current figures before acting.

Ares Capital (ARCC) has raised its dividend for nine or more consecutive years. It is the category leader by assets and benefits from scale advantages in origination and access to the Ares credit platform. Blue Owl Capital (OBDC) received a Moody's Baa2 credit rating upgrade in January 2026, which signals improving balance sheet quality and should lower its cost of borrowing over time. FS KKR Capital (FSK) offers the highest stated yield of the three but carries a higher leverage ratio and saw its NAV decline from $20.89 per share in Q4 2025 to $18.83 per share in Q1 2026, a signal worth examining carefully.
