A USD facility signed while the exchange rate slept becomes a burden when the currency slips double digits in a year: the converted principal grows, interest accrues on a bigger base, and foreign loan contracts contain almost no rate-sharing clause for the borrower. The company must separate what is strictly payable from what remains negotiable.
What a foreign loan obliges the company to do
A Vietnamese company’s foreign loan operates inside the foreign-exchange control frame: medium- and long-term loans must be registered with the State Bank, drawdowns and repayments move through designated accounts as prescribed, and the borrower reports loan performance periodically. Contractually, the duty to repay principal and interest in the agreed currency does not change with the exchange rate — the rate only changes the dong burden on the books and in real cash flow. The company must also watch the loan’s tax layer, including foreign contractor tax on interest paid to an offshore lender under the prevailing tax framework.
Levers when the rate moves against you
The first lever is restructuring with the lender itself: extension, partial conversion into dong where the lender has a Vietnamese presence, or a rescheduled amortisation matched to new cash flow. The second lever is hedging the remaining exposure with derivatives at a domestic credit institution, such as forwards, where the company can evidence a real foreign-currency need from the loan. The third is building a natural hedge — pushing export revenue or collecting foreign-currency receivables into the same windows as debt service — to cut net exposure rather than only buying price insurance. Every option must be cross-checked against the State Bank loan registration before signing, because changing tenor or lender may require a registration amendment.
Points to close with the servicing bank and the lender
- Build an exposure table by repayment date for the next twelve months and the rate level at which cash flow breaks — that figure anchors every negotiation.
- Ask the servicing bank about forward limits and conditions for genuine debt-service needs, supported by the registered loan file.
- Review the loan’s tax clauses (who bears contractor tax on interest) before costing any restructuring option.
Frequently Asked Questions
Does a rate move change what we owe?
No. The duty to repay in the contract currency is unchanged; the exchange rate only enlarges the converted burden and the finance cost recognised by the company, unless the contract carries a specific adjustment clause the parties agreed.
What can be done about the exposure?
Restructure tenor or partially convert with the lender, use forwards at a domestic bank for genuine repayment needs, and build foreign-currency revenue matched to repayment windows; amendments to a registered loan require a registration change with the State Bank.
What about interest withholding?
Interest paid to a foreign organisation or individual falls within foreign contractor tax under the prevailing framework; the rate and withholding mechanics follow the contract and the tax guidance in force at payment time.
Who bears the exchange risk?
The borrower, as a matter of contract; the State runs no compensation scheme for commercial loan rate losses. The only protections are contract clauses, derivatives and the company’s own natural foreign-currency inflows.
