Debt Portfolio Management Can't Live in Spreadsheets

TL;DR

US companies issued roughly $1.52 trillion in corporate bonds in the first half of 2026, up over 28% year over year, with investment-grade spreads near their tightest levels since 1998. Every new tranche adds covenants to track, maturities to ladder, and rate and currency exposures to balance — a workload that breaks spreadsheet-based tracking. Debt portfolio management needs to move into daily treasury operations, connected to cash positions and forecasts, so obligations, covenants, and debt service costs live in one real-time view.

Companies Are Borrowing Like It's 2020 Again. Debt Portfolio Management Hasn't Caught Up.

Big corporations are on a massive borrowing spree. In the first half of 2026, US companies issued roughly $1.52 trillion in corporate bonds, up over 28% from last year, according to SIFMA, with the first quarter marking the highest quarterly issuance total since 2020. Tech giants and data center operators account for much of it, taking on record amounts of debt to fund AI infrastructure.

Companies are moving quickly because the market is making it extraordinarily cheap for large, highly rated corporations to borrow. Investors treat these businesses as low-risk, with spreads hovering near 0.77% above US Treasury rates, close to the tightest levels since 1998.

Between these historically low spreads, upcoming debt payments coming due, and expensive AI expansion plans, finance teams are piling new loans onto their balance sheets at lightning speed.

From a strategic standpoint, it's a useful window to fund future growth. But for treasurers, managing a large debt portfolio on 2010-era spreadsheets is a growing operational risk.

The Invisible Operational Headaches of Heavy Borrowing

When a company executes a new bond offering, executive teams celebrate the low interest rate, the headline pricing, and the successful capital raise. But for the treasury and finance teams working behind the scenes, the deal signing is the start of a major operational workload.

Every new loan, bond tranche, or credit line added to the capital structure creates an ongoing management burden that lasts for years. When a company stacks multiple issuances back-to-back, that burden compounds.

1. Navigating Complex Loan Rules (Covenants)

Every credit agreement comes with legal promises, known as covenants. These might require a company to keep its total debt below a certain multiple of its earnings, maintain a minimum amount of liquid cash, or restrict how much money can be spent on stock buybacks or dividends.

Tracking these rules across one or two bank loans is simple enough. Tracking them across fifteen bond tranches, three revolving credit lines, and localized term loans across global subsidiaries quickly becomes unmanageable. A single oversight can trigger a technical default, causing interest rates to spike or giving lenders the right to demand immediate repayment.

2. Preventing Maturity Bottlenecks

A company's debt portfolio must be carefully structured so that payment deadlines are spread out over time, in a process known as laddering maturities. If a company allows $5 billion of debt to come due in the same quarter that it faces major capital expenditures, it creates a dangerous liquidity bottleneck. Managing these due dates requires constant vigilance, especially when market conditions change and planned refinancings need to be moved up or pushed back.

3. Balancing Hidden Interest and Currency Exposures

Issuing debt is rarely as simple as paying a fixed interest rate in US dollars. Larger debt portfolios often feature a mix of fixed-rate bonds, floating-rate bank loans, cross-currency swaps, and localized foreign exchange hedges.

When interest rates fluctuate or foreign currencies shift, the total cost of servicing that debt changes daily. If treasury teams are tracking these variables across separate files, they cannot get an accurate, real-time view of what their total debt actually costs the business.

When a company only borrows money once every few years, finance teams can get away with tracking these variables in static spreadsheets. But during a high-volume borrowing spree, spreadsheet management breaks down completely.

When your balance sheet moves this fast, a broken spreadsheet formula, a missed column update, or a delayed month-end report can cause a missed loan covenant or a miscalculated cash payment.

Why Debt Needs to Be Part of Daily Cash Management

To keep pace with modern corporate borrowing, debt portfolio management can no longer exist as a siloed, quarterly exercise that lives in a finance manager's desktop folder. It must evolve into a core component of daily treasury operations and cash flow forecasting.

Historically, companies treated debt tracking as an accounting job. At the end of the quarter, someone would look at the debt schedules, calculate the accrued interest, plug the numbers into a report, and send it off to leadership.

That backward-looking approach fails in a fast-moving market. When debt structures, short-term funding lines, and daily bank balances live in separate, disconnected systems, corporate treasurers face three major operational blind spots:

Blind Spot 1: No Combined View of Short- and Long-Term Obligations

A high-volume issuance year dramatically alters when cash needs to leave the building. A company might have a $500 million bond maturity coming up in eighteen months, a $50 million commercial paper payment due next week, and a quarterly coupon payment on a floating-rate loan due in two days.

If treasury leadership cannot see every one of these obligations combined in one dashboard alongside their cash balances, they cannot make smart decisions about whether to use excess cash to pay down debt or invest in new projects.

Blind Spot 2: Reactive Covenant Tracking

Waiting until the quarter closes to calculate covenant ratios means finding out about a breach after it has already happened.

If operational costs rise unexpectedly or sales dip during a quarter, a company might unknowingly drift toward breaching a leverage covenant. Modern finance teams need live scenario modeling software that lets them directly see the potential outcomes should sales figures or interest rates materially change.

Blind Spot 3: Disconnected Cash Forecasting

Floating-rate debt costs fluctuate constantly. Coupon schedules hit at different times of the month. Every debt payment directly alters a company's net cash position.

When treasury staff have to manually copy payment dates and coupon amounts out of debt contracts and paste them into cash forecasting spreadsheets, they introduce significant room for human error. Debt service costs should flow directly into liquidity projections automatically, updating in real time whenever interest rates change or new bonds are issued.

Unifying Capital Markets and Daily Treasury

As corporate debt structures grow larger and more complex, keeping track of major debt issuances in the same system used for daily cash tracking is essential.

This operational change is precisely why enterprise treasury platforms are rushing to expand their capital markets capabilities. Rather than managing cash in one tool, bank accounts in another, and multi-billion-dollar debt portfolios in offline spreadsheets, modern finance departments are consolidating these functions into one system.

Trovata TMS connects bank data directly to debt facility schedules, bringing every bond tranche, term loan, credit facility, and investment instrument into one view.

Instead of relying on brittle, disconnected schedules, treasury teams gain complete, live visibility into global debt obligations, accrued interest expenses, and active covenants.

Because loan positions feed directly into an automated cash forecasting engine, liquidity managers no longer have to guess how a new $500 million bond issue will impact their daily cash buffer over the next three years. They can see the precise impact on cash flow, debt service capacity, and overall balance sheet health instantly.

Modernizing Corporate Treasury for a High-Volume Era

The current wave of corporate borrowing shows no signs of slowing down. As companies continue to fund long-term strategic initiatives, build out next-generation AI infrastructure, and navigate upcoming refinancing walls, high-volume bond issuance will remain a defining feature of corporate finance.

Historically low credit spreads and eager capital markets offer fantastic opportunities to raise capital on favorable terms. But taking on the money is only step one.

The companies that come out ahead won't be the ones that land the headline bond deals at great pricing, but the ones equipped to manage those debt portfolios cleanly, safely, and efficiently long after the deal closes.

If your company is borrowing like it's 2020, it's time to retire the manual spreadsheets and ensure your debt management software and treasury systems are built for 2026. Book a demo today.

FAQs

What is debt portfolio management?
Debt portfolio management is the ongoing tracking and structuring of every borrowing a company carries: bonds, term loans, revolving credit lines, and commercial paper. It covers covenants, maturities, interest costs, and currency exposures, and connects those obligations to daily cash positions and forecasts.

Why is corporate borrowing so high in 2026?
Borrowing is unusually cheap for large, highly rated companies, with investment-grade spreads hovering near 0.77% above US Treasury rates, close to the tightest levels since 1998. SIFMA data shows roughly $1.52 trillion in US corporate bonds issued in the first half of 2026, up over 28% from last year, much of it funding AI infrastructure.

What are debt covenants and why are they hard to track?
Covenants are the legal promises in a credit agreement, such as keeping total debt below an earnings multiple or maintaining minimum liquidity. They're manageable across one or two loans, but tracking them across fifteen bond tranches, multiple credit lines, and localized term loans in spreadsheets invites a missed threshold — and a single oversight can trigger a technical default.

What is maturity laddering?
Maturity laddering spreads debt repayment deadlines out over time so no single quarter concentrates too much repayment risk. If billions come due in the same quarter as major capital expenditures, the company faces a liquidity bottleneck, so treasury teams monitor the ladder constantly and restructure as market conditions change.

Why should debt live in the same system as daily cash management?
Every coupon payment, maturity, and floating-rate reset changes the company's net cash position, so debt data kept in offline spreadsheets leaves cash forecasts blind. Connecting debt schedules to live bank data shows how each obligation affects cash flow, debt service capacity, and covenant headroom in real time.

How does Trovata TMS handle debt portfolio management?
Trovata TMS brings bond tranches, term loans, credit facilities, and investment instruments into one view alongside live bank data, with debt service costs flowing directly into automated cash forecasting. Treasury teams get continuous visibility into obligations, accrued interest, and active covenants instead of quarter-end reconstructions.
