When I write about indian corporate bonds, I try to keep one thought in front of me: a bond is a promise, but the shape of that promise changes from one issuer and one structure to another. If I treat every corporate bond as the same product, I end up comparing numbers that are not truly comparable. That is why I always start with categories. Once I know what category a bond falls into, the risks become easier to see, and the return starts to make sense.

Secured and unsecured: what I am relying on

A large part of the story in types of corporate bonds is simply whether the bond is secured. If it is secured, there is usually a specific asset pool—like receivables or property—identified as support for the borrowing. If it is unsecured, my repayment depends more directly on the issuer’s overall balance sheet and ongoing cash generation.

I find this distinction helpful because it forces a practical question: If the issuer goes through stress, what is the path to recovery? With secured bonds, that path can be clearer. With unsecured bonds, the path can be longer and more dependent on the issuer’s wider financial position. Even then, I remind myself that “secured” is not a magic word. The quality of the collateral, the legal structure, and whether the same assets are already pledged elsewhere all matter.

Senior and subordinated: where I stand in the queue

Not all bondholders stand in the same line. Senior bonds are generally higher in priority, which means they are expected to be paid before subordinated instruments if things turn difficult. Subordinated bonds take losses earlier and therefore tend to offer higher yields.

Whenever I compare indian corporate bonds, I treat this as a core factor, not a footnote. A bond can look attractive on yield, but if it sits lower in the repayment hierarchy, the “extra” return is often compensation for that position. This is why categorising a bond by seniority helps me avoid false comfort.

Fixed-rate and floating-rate: certainty has a price

Fixed-rate bonds feel straightforward because the coupon is visible upfront. I know what I will receive and when. But if interest rates move up, a fixed-rate bond can lose market value. That may not matter if I hold till maturity, but it matters a lot if I want flexibility.

Floating-rate bonds adjust their coupon against a benchmark, which can reduce interest rate sensitivity. However, I do not assume floating-rate is automatically safer. I check the reset frequency, the spread, the benchmark used, and what happens to the cash flows during volatile rate cycles. These details are a big part of understanding types of corporate bonds properly.

Listed and unlisted: liquidity is not a bonus, it is a risk control

Liquidity is one of the most human, real-world considerations in indian corporate bonds. A listed bond may offer better transparency and easier access to pricing, but liquidity still varies widely from one bond to another. Unlisted bonds can offer limited exit options and fewer observable market quotes, which can make decision-making harder if circumstances change.

I ask myself a simple question: Am I comfortable holding this bond all the way to maturity? If the honest answer is “maybe not,” then liquidity becomes a serious part of the risk profile.

Credit risk: ratings help, but I look beyond them

Credit ratings are useful, but they are not the full picture. I also look at cash flow stability, leverage, refinancing needs, and how the issuer behaves across business cycles. I pay attention to covenants and payout structures as well, because the fine print can influence outcomes far more than most investors expect.

The way I bring it together

For me, the best way to approach types of corporate bonds is to categorise first, compare second. I look at structure (secured/unsecured, senior/subordinated, fixed/floating), then issuer quality, then liquidity, and finally the bond’s documentation. This sequence keeps my decisions grounded in reality. It also helps me remember that in corporate bonds, return and risk are closely linked—so understanding the category is not just educational; it is what makes the investment decision defensible.
