Vietnam's banks booked record profits, but VPBank has not collected 10 trillion dong of the interest it reported

Are Vietnam's bank profits as strong as they look? The headline numbers are impressive, but the cash tells a more cautious story. VPBank's nine month pre tax profit jumped 46.7 percent to 29.91 trillion dong and Techcombank's rose 23.7 percent to 28.92 trillion dong, yet both banks collected a smaller share of their reported interest income in cash than a year earlier, according to an analysis by The Investor.

At VPBank, the gap between interest booked and interest collected has reached about 10.15 trillion dong, roughly 400 million dollars. That is money the bank has counted as income but has not yet received from borrowers. For investors, depositors and regulators, the difference between accounting profit and cash collected is one of the earliest signs of whether a lending boom is healthy or storing up problems.

Strong headline profits

Vietnam's lenders have had a good year on paper. Credit growth has been strong as the government pushes banks to support economic expansion, and several banks reported sharp profit increases for the first nine months of 2026. ABBank's pre tax profit surged 86.9 percent to 4.3 trillion dong, VPBank's rose 46.7 percent and Techcombank's climbed 23.7 percent. LPBank posted a more modest 8.4 percent increase to 10.42 trillion dong.

The growth reflects expanding loan books, higher fee income and in some cases lower provisioning costs. But reported profits are built on accounting rules that allow banks to recognise interest income when it is earned, not when it is paid. That is why analysts look at cash flow statements alongside income statements.

This distinction matters most during periods of rapid credit growth. When loan books expand quickly, interest income rises on paper straight away, while any weakness in borrowers' ability to pay takes longer to show up in bad debt figures. The cash flow statement offers an earlier window into whether borrowers are actually paying what they owe.

The gap between booked and collected interest

The Investor compared each bank's recognised interest and similar income with the cash it actually collected from interest during the period. At VPBank, interest and similar income reached 107.19 trillion dong, but cash received from interest was 97.05 trillion dong. The collection ratio fell to 90.5 percent from 93.57 percent a year earlier, leaving a gap of around 10.15 trillion dong.

Techcombank's figures were stronger but moving in the same direction. It recognised 68.14 trillion dong of interest income and collected 64.36 trillion dong in cash, a ratio of 94.46 percent, down from 95.77 percent. A falling ratio means a growing share of reported interest is accrued, recorded as receivable but not yet paid by borrowers.

Profit is an opinion and cash is a fact. When a bank books 10 trillion dong more interest than it collects, investors should ask who has not paid yet.

Accrued interest is not automatically bad. Some loans pay interest at the end of a term, and fast growing loan books naturally build up receivables. But when the gap widens while the economy faces pressure from high oil prices and a weak global trade outlook, it can be an early sign that some borrowers are struggling to keep up.

The gap is not unique to VPBank and Techcombank, but the size of the move at VPBank stands out because it is one of the country's most aggressive lenders, with a large consumer finance business. Consumer loans typically carry higher interest rates and higher default risk than corporate loans, so changes in collection patterns there can be an early signal of household stress.

Why regulators are watching accrued interest

The State Bank of Vietnam has paid attention to accrued interest before. Its Official Dispatch 9608 addresses how banks should handle interest that has been recorded but not collected, part of wider efforts to make sure reported profits reflect real cash. Vietnamese banks have historically faced scrutiny over loans to property developers and corporate bond issuers, where restructured loans can allow interest to be accrued rather than paid.

Monetary policy adds another layer. The central bank has been steering lenders to cut lending rates and support growth, as we covered in our report on the State Bank of Vietnam's push for rate cuts. Lower rates can ease pressure on borrowers, but they also squeeze bank margins, making the quality of reported income even more important.

Accrued interest also has tax and dividend implications. Profits that include large amounts of uncollected interest can still be taxed and distributed to shareholders, even though the cash has not arrived. If some of that interest later proves uncollectable, banks must reverse it or set aside provisions, which can hit future earnings.

What investors should watch

For investors in Vietnamese bank stocks, which have been among the market's largest weights, the cash collection ratio is a useful complement to headline profit growth. The key indicators to monitor include:

• The ratio of cash collected to interest income recognised
• Growth in accrued interest receivable on balance sheets
• Restructured loans and loans in special mention categories
• Exposure to real estate developers and corporate bonds
• Provisioning levels relative to reported bad debt

None of these numbers on its own proves a problem. Together, they show whether profit growth is translating into cash, the ultimate test of a bank's health.

Investors can find most of these figures in banks' quarterly financial statements, particularly the cash flow statement and the notes on loan classification. Comparing several quarters helps separate one off swings from lasting trends, and comparing banks side by side shows which lenders are converting profit into cash most reliably.

What it means for Vietnam's banking sector

Vietnam joined FTSE Russell's emerging market benchmarks on 21 September 2026, an upgrade expected to draw billions of dollars of foreign inflows into its stock market, with banks among the main beneficiaries. That makes transparency on earnings quality even more important, because foreign investors tend to look closely at cash flow and asset quality.

For the banks themselves, the challenge is balancing rapid credit growth demanded by policymakers with careful risk management. A widening gap between accounting profit and cash collected is not a crisis, but it is a signal that deserves attention before it becomes one.

The FTSE milestone was widely covered, including by The Business Times, and index inclusion tends to bring more analyst coverage and tougher questions from global fund managers. Bank managements that can show strong cash conversion alongside profit growth are likely to command higher valuations than those whose earnings rely more on accruals.

Vietnam's banks have delivered impressive profit growth in 2026, but the gap between interest booked and interest collected is widening at some of the largest lenders. VPBank's 10 trillion dong shortfall is not proof of a problem, yet it is exactly the kind of signal that investors and regulators should track. As Vietnam draws foreign capital after its FTSE upgrade, the quality of bank earnings will matter as much as their size.
