Vietnam bond talks test rising dollar debt costs for Hanoi

Vietnam bond talks center on a possible $1 billion 10-year sale to fund infrastructure as Hanoi seeks faster growth through 2030.

Vietnam's Ministry of Finance has discussed possible terms with foreign investment banks, four people familiar with the talks said. Two of the people said proceeds would be directed toward infrastructure and other state projects, part of a growth agenda that targets annual expansion of at least 10% through 2030.

The ministry has not decided whether to proceed, two Vietnamese officials said. They said the government is assessing dollar borrowing costs at a time when global yields have risen as high oil prices and inflation shape financing conditions.

Bank proposals set a range

One foreign investment bank . A second foreign lender proposed a 10-year deal between $500 million and $1 billion, with a coupon around 7%, according to another person briefed on the recommendation.

A sale on those terms would be Vietnam's first offshore sovereign dollar bond since 2014, when it raised $1 billion through a 10-year note carrying a 4.8% coupon. The suggested 7% coupon would be 2.2 percentage points above that 2014 level, illustrating the higher price of external funding now under discussion.

Vietnam also tapped international bond markets in 2010 and 2005, but it has long kept a cautious stance toward overseas borrowing. Public debt was estimated at around 37% of gross domestic product last year, while the financial system remains closely managed by the state.

Domestic coupons have climbed

The government has raised more than $9 billion in the domestic bond market so far this year, broadly in line with the same period a year earlier. The average coupon on 10-year local-currency debt was 4.2%, up 1.1 percentage points from 3.1% in the comparable period.

That domestic comparison is central to the finance ministry's choice. A dollar bond could broaden funding sources and create a fresh offshore benchmark, but it would also expose the sovereign to foreign-currency repayment risk and a coupon above current 10-year domestic borrowing costs.

The discussions come as Vietnam's export-heavy economy faces uncertainty in global trade, a main channel for growth. The Communist Party under General Secretary To Lam has pressed for faster expansion, and foreign financing has become a more visible part of that policy mix.

Vingroup taps overseas buyers

Pressure is also visible inside the banking system. Vietnamese banks have recorded credit growth above deposit growth since at least 2021, central bank data show, a gap that can increase demand for offshore funding when domestic liquidity tightens.

The State Bank of Vietnam this year raised the ceiling for private-sector foreign borrowing to $6.1 billion, compared with $5.5 billion in 2025. One official familiar with the matter said the cap may be raised again later this year as banks seek approval for overseas borrowing plans.

Companies have already moved in that direction. Vingroup, Vietnam's largest conglomerate, issued a $350 million five-year bond on the Vienna Stock Exchange in April with a 5.75% coupon, and a filing showed it also plans to raise 455 billion won ($338 million) from South Korean investors through three-year bonds carrying an 8% coupon.

Three dollar funding paths

If Vietnam proceeds with a roughly $1 billion 10-year sovereign issue, the macro effect would be small in global capital markets but useful as a price signal for Asian frontier and emerging borrowers. For the sovereign, the mechanism is direct: higher dollar costs buy immediate infrastructure funding and an offshore curve that banks and companies could reference.

If the ministry delays or drops the sale, domestic bonds and development loans would remain more important funding channels. That path would limit foreign-currency exposure for the state, but it could leave local banks and corporate issuers competing harder for domestic savings if credit growth continues to outpace deposits.

A third path is wider foreign borrowing without an immediate sovereign dollar deal. If the private-sector ceiling rises again and development loans from Japan and Germany expand, Vietnam could bring in external capital gradually while testing investor demand before committing the sovereign balance sheet to a new offshore coupon.
