Corporate finance sounds like something reserved for boardrooms and investment bankers in expensive suits. In reality, treasury lives right in the middle of it, quietly making sure the company doesn’t run out of money while everyone else is busy building strategy decks.
At its core, corporate finance within treasury is about one thing: how the company funds itself and how it manages that funding over time.
Every company needs capital to operate and grow. That capital can come from different sources, broadly split into equity and debt. Equity is ownership. Debt is obligation. One dilutes control, the other creates fixed commitments. Choosing the right balance between the two is what we call capital structure.
Sounds simple. It isn’t.
The Role of Treasury in Capital Structure
Treasury doesn’t just “execute” financing decisions. It shapes them.
It looks at:
The goal is not to find the cheapest funding option in isolation. The goal is to build a funding structure that is resilient, flexible, and aligned with the company’s strategy.
Cheap debt that locks you into restrictive covenants can become very expensive the moment business conditions change.
Debt: More Than Just Borrowing Money
Debt comes in many forms. Bank loans, revolving credit facilities, bonds, private placements. Each has different characteristics in terms of maturity, pricing, flexibility, and investor base.
Treasury decides:
And then comes the part everyone underestimates: managing it over time.
Debt isn’t a one-off decision. It requires ongoing monitoring. Refinancing moments need to be anticipated. Market windows open and close. Interest rates move. Suddenly that “good deal” from two years ago looks less attractive.
Equity: The Expensive Silence
Equity doesn’t come with interest payments, which makes it look easy. It isn’t.
Equity is typically more expensive than debt when you look at the cost of capital. It also dilutes ownership and control. Treasury is not always directly responsible for raising equity, but it absolutely influences when it makes sense.
In high uncertainty environments, companies often lean more towards equity to reduce financial risk. In stable environments, they may optimise towards debt to improve returns.
Again, it’s a balance. Always a balance.
Liquidity vs Profitability
Here’s where treasury annoys everyone else in the company.
From a pure profitability perspective, you want minimal idle cash and efficient use of capital. From a treasury perspective, you want buffers. Liquidity cushions. Access to funding even when markets turn ugly.
Holding cash has a cost. Not having cash has consequences.
Treasury constantly navigates that trade-off. Too conservative, and you drag down returns. Too aggressive, and you risk liquidity stress at exactly the wrong moment.
Capital Structure Is Not Static
One of the biggest misconceptions is that capital structure is something you “set” and then move on from.
It evolves.
Growth requires funding. Acquisitions change leverage. Market conditions shift. Interest rates rise or fall. Regulations change. Investor expectations move.
Treasury continuously reassesses:
Because yes, credit ratings matter. A downgrade can increase funding costs overnight and reduce access to capital markets.
The Hidden Layer: Optionality
Good treasury teams don’t just optimise for today. They build optionality.
Undrawn credit lines
Diversified funding sources
Access to multiple markets
Flexible debt structures
These don’t always look efficient on paper. But when things go wrong, they become invaluable.
And things do go wrong. Regularly.
Where It Goes Wrong
This is the part people don’t like to talk about.
Most capital structure problems don’t come from complex financial engineering. They come from basic misalignment and lack of forward thinking.
Treasury’s Real Contribution
A strong treasury function brings structure, discipline, and realism into corporate finance decisions.
It asks uncomfortable questions:
Not because it enjoys being pessimistic, but because someone has to think about downside scenarios before they happen.
In the end, capital structure is not about optimising a formula. It’s about ensuring the company can survive, adapt, and grow without constantly worrying about its financial foundation.
Which, when you think about it, is kind of important.
