How Does the VND/USD Exchange Rate Move? FX Risk for Foreign Investors

Modern office building complex — a financial and business district

The Vietnamese dong (VND) operates under a daily central exchange rate announced by the State Bank of Vietnam (SBV), with commercial banks trading within a permitted band around it. For foreign investors, the core question is not “what is the rate today” — that changes daily — but: what may a business do with foreign currency, and how can exchange-rate risk be locked in when repatriating profits?

The Exchange Rate Through the Macro Lens: Why Has It Held?

Exchange rates do not move in a vacuum. What has underpinned the VND in recent years is the macro picture itself: GDP growth of 7.09% (2024) and 8.02% (2025) — the highest in ASEAN — with CPI rising only 3.63% then 3.31%, inside the National Assembly’s target. When domestic inflation is low and stable, the inflation gap with trading partners does not widen — the precondition for the exchange rate to avoid mechanical depreciation pressure.

Foreign-currency supply is also ample thanks to trade: 2025 import-export turnover topped USD 930 billion (up 18.2%), exports USD 475 billion — FX inflows from exports and disbursed FDI cushion the balance of payments. On that foundation, the State Bank of Vietnam manages the rate through a daily-published central rate, letting the market move within a band while keeping the policy anchor. Investors should grasp this logic: the VND does move, but within a managed framework — not a free float.

Three Macro Indicators to Read as FX Signals

Rather than guessing the rate day by day, watch three signals: (1) the Vietnam–US/EU inflation gap — the lower domestic inflation, the smaller the depreciation pressure; (2) the trade balance and disbursed-FDI flows — the larger the surplus, the more abundant USD supply; (3) the SBV’s policy stance as expressed in the daily central rate. When all three point the same way, corporate hedging costs fall materially.

Track three numbers monthly: the SBV central rate, the trade balance, and the inflation gap with the US. When all three are stable, hedging can stay light; when any one turns, tighten cover.

The VND/USD Mechanism: What Investors Must Grasp

Unlike fully free-floating currencies, the VND is managed via a central-rate mechanism: each business day, the SBV announces a central VND/USD rate reflecting domestic and international market developments; credit institutions may trade within a defined band around it. This delivers controlled flexibility — no abrupt shocks — a macro-stability plus many investors value when comparing Vietnam with other emerging markets.

“Managed stability” does not mean “frozen”, however. The VND still moves cyclically: when the USD strengthens globally or the USD–VND interest-rate gap widens, the dong typically faces relative depreciation pressure; conversely, strong FDI inflows, remittances and trade surpluses ease the pressure. Long-term investors should read the exchange rate as a multi-year trend, not weekly noise.

What May FDI Enterprises Do with Foreign Currency?

Vietnam’s foreign-exchange regulations allow foreign investors to open and use foreign-currency accounts at authorised banks; investment capital, profits and other lawful earnings may be transferred abroad after fulfilling financial obligations to the State. The general rule: payments within Vietnam’s territory are made in VND, except where the law permits foreign-currency use (e.g., certain transactions with authorised credit institutions, or payments in export-processing zones as regulated).

A key practical point: contracts between an FDI enterprise and domestic partners are in principle denominated in VND; if you wish to link to foreign currency, structure the clause in compliance with the regulations and seek legal advice before signing — a non-compliant forex clause may be partially invalidated.

Tools to Hedge Exchange-Rate Risk

Rather than “guessing” the rate, businesses can lock in risk with currency derivatives at authorised commercial banks: forwards — fixing a future buy/sell rate in advance, suitable for certain cash flows (e.g., scheduled profit repatriation to the parent); swaps — combining spot and forward legs to manage forex liquidity; options — paying a premium for the right (not the obligation) to transact at an agreed rate, suitable when cash flows are uncertain.

A practical strategy for new investors: (1) budget the project under a conservative exchange-rate scenario (3–5% buffer); (2) naturally match cash flows — raise the VND-cost share when revenues are in VND; (3) use forwards for large scheduled transfers; (4) follow SBV policy signals closely rather than market rumours.

Regional Comparison: the VND in ASEAN’s Currency Race

Set against ASEAN peers, the VND’s position looks different: Thailand and Malaysia grow only 2–3% a year, Indonesia about 5%, while Vietnam holds 5–8% with GDP near USD 514 billion (2025). Faster growth usually brings bigger depreciation pressure — but Vietnam offsets it with low inflation (3.63%, then 3.31%) and a trade surplus on USD 930 billion of turnover. The message for investors: the VND is not the currency of a stagnant economy forced to devalue for exports, but of a growing economy that needs stability to attract long-term capital.

On medium-term flows, the flagship infrastructure programme (North–South expressway, Long Thanh airport, metros, deep-sea ports) will keep pulling in FDI and foreign-currency borrowing — both a source of USD supply and a reason exchange-rate policy must stay steady so as not to inflate these projects’ costs. In other words, FX stability is not only a monetary goal but a condition for the public-investment–FDI machine to run.

FX Scenarios and the FDI Firm’s Hedging Toolkit

Alongside the base case (movement within the managed band), firms should prepare for two situations: (1) a globally strong USD — the SBV may widen the band or adjust the central rate faster; the response is locking rates ahead with forwards for large payables; (2) a trade shock — US reciprocal tariffs or EU barriers slowing exports and shrinking USD supply; the response is currency swaps and options to stay flexible. The golden rule: hedging always costs less than an unprepared shock — build the exchange rate into the financial model from day one, updated against the SBV’s daily central rate, instead of treating it as a “later” risk.

Beyond financial instruments, consider natural hedges. Firms that both import inputs and export finished goods in USD carry a built-in offset — the managed framework keeps the residual manageable. Others can shift exposure contractually: price long-term domestic supply contracts in VND with indexation clauses, align payment terms with FX inflow and outflow timing, and keep a USD liquidity buffer sized to a few months of net payables. Review the hedge mix quarterly against the central-rate trend — a hedging programme set once and forgotten decays as trade patterns shift.

Exchange-Rate Risk Checklist for New Investors

  • Understand the mechanism: track the daily SBV central rate — the market’s official anchor.
  • Open a forex account: work with an authorised bank from the capital-contribution stage so cash flows run smoothly.
  • Draft compliant contracts: every forex clause in domestic contracts should be reviewed by counsel under foreign-exchange regulations.
  • Pick hedging tools: forwards for certain cash flows, options for uncertain ones — ask banks about fees and terms.
  • Legal advice: contact FLAT Law Firm to structure capital flows and repatriate profits in full compliance while optimising tax.
