Decree 323 Pitches VIFC Sandbox as 30-Year Bond Lab
PM Le Minh Hung's April 2026 directive on 15-30 year infrastructure bonds meets a novel proposal: use the VIFC's Decree 323 sandbox to pilot VND sovereign debt for foreign buyers.
Prime Minister Le Minh Hung's late-April 2026 instruction to the Ministry of Finance and Ministry of Construction — research mechanisms for 15-30 year government bonds for foreign investors, linked to specific infrastructure projects — opens a policy window that did not exist six months ago. The question is which legal vehicle carries the pilot. One proposal gaining traction in academic and practitioner circles names the VIFC's Decree 323 sandbox as the answer.
The Financing Gap That Creates the Policy Pressure#
The numbers behind the PM's directive are stark. Total social investment requirements for 2026-2030 are reported at approximately VND 38.5 million billion — roughly $1.5 trillion — double the previous five-year period. The National Assembly's medium-term public investment plan allocates VND 8.22 million billion in public capital, covering only 20-22% of that requirement. These figures come from the Government Portal citing MoF calculations; they have not been independently verified against the National Assembly resolution text, and practitioners should model against confirmed sources before using them in investment cases.
Closing the gap requires average total investment growth of 16% per year and an investment-to-GDP ratio averaging 40% — neither achievable without deep-market debt instruments. Infrastructure assets with 20-30 year operational lives need financing that matches that duration. Vietnam's domestic bond market, historically concentrated below the 10-year mark and illiquid beyond 5-7 years, does not currently provide it.
Where the Sandbox Comes In#
Dr. Le Dat Chi, Head of Finance at the University of Economics Ho Chi Minh City, argues that the VIFC's existing sandbox architecture is the logical pilot venue. The legal basis is clear: Resolution 222/2025/QH15, effective 1 September 2025, authorizes controlled pilot financial policies for fintech and financial innovation within the VIFC. Decree 323/2025/ND-CP, effective 18 December 2025, operationalizes this by granting the VIFC-HCMC operating agency authority to license products and technologies with no existing legal framework — with a maximum pilot term of five years.
The argument is that a long-term VND-denominated sovereign bond for foreign buyers fits precisely this category: a financial product that Vietnam's current securities and capital market rules do not accommodate for the foreign investor base. The sandbox mechanism creates a controlled environment to test issuance mechanics, investor demand, custody arrangements, and secondary market behavior before the MoF commits to a full-scale program.
The proposal has real logic. The VIFC framework already contemplates that the operating agency may use city budget resources to compensate sandbox participants for unforeseeable risks during testing — a provision that matters when asking foreign institutional buyers to commit capital to an untested instrument in a market they do not fully know. See the VIFC's eight implementing decrees for the broader sandbox governance map.
The Unresolved Tension: Five-Year Sandbox, 30-Year Bond#
The most obvious structural problem with this proposal sits in plain sight: Decree 323 permits a maximum five-year controlled pilot. A 15-30 year bond cannot be piloted to maturity within that window. What the sandbox could test, however, is narrower and more tractable: issuance mechanics, secondary market liquidity, FX management, and investor settlement processes for the first tranches. The bond itself need not mature within the pilot — the sandbox tests the infrastructure around it, not the instrument's full lifecycle.
Whether this interpretation satisfies the MoF's legal risk appetite is a separate question. The MoF will need to decide whether a sovereign guarantee or direct Treasury issuance outside the sandbox structure — with the sandbox validating procedures, not the instrument — is the cleaner structure. That legal analysis has not been completed.
The Stablecoin Collateral Layer#
The more novel element of Dr. Le Dat Chi's proposal — as set out in his published academic commentary on VIFC financial innovation mechanisms (UEH Finance Faculty working paper, Q1 2026) — is a Vietnamese stablecoin mechanism modelled loosely on the US Stablecoin Act framework. The mechanism as proposed works in four steps:
- A foreign investor purchases a Vietnamese stablecoin using foreign currency.
- The stablecoin is 100% collateralized by long-term VND government bonds.
- The investor earns a fixed-rate return on those bonds while operating within the VIFC ecosystem.
- The sandbox manages FX risk exposure during the pilot period.
The attraction is that it routes around Vietnam's foreign exchange restrictions on direct VND bond investment by creating an intermediary instrument — the stablecoin — that foreign investors hold instead. The stablecoin absorbs FX risk structurally (since it is VND-denominated under the hood) while giving the investor a dollarised entry point.
This is expert commentary, not government policy. It requires the framework established under Resolution 05/2025/QH15 (the National Assembly resolution governing digital assets and crypto exchange licensing, passed in early 2025) — which governs crypto exchange licensing and digital asset issuance — to interact with the MoF's bond issuance architecture in a way that neither framework currently anticipates. Vietnam's two-track digital asset architecture, with the VIFC operating under Resolution 05/2025/QH15 and the national crypto pilot proceeding separately, creates real jurisdictional complexity for a product that would need to live in both worlds. The Resolution 05 RWA issuance compliance framework is the closest existing analogue, but sovereign bonds as RWA collateral remain outside its current scope.
Practitioners interested in the stablecoin-bond nexus should also note that Vietnam has listed stablecoins as a VIFC priority sector — which signals policy appetite without creating an implementation pathway.
Two Pre-Conditions Neither Proposal Solves#
Dr. Le Dat Chi identifies what he considers the non-negotiable prerequisites for any long-term sovereign bond program to attract foreign demand: a functioning secondary market and liquidity in that market. Without both, a foreign institution buying a 15-year VND bond accepts the risk of being locked in for the full term — an unacceptable constraint for most asset-liability management frameworks.
The proposed solution is SBV functioning as a discount facility, standing ready to purchase government bonds from holders who need liquidity. Whether the SBV has appetite for that role — and whether its current balance sheet and inflation mandate permit it — is not addressed in the academic proposal. The SBV's own Basel III transition work already constrains its ability to expand its government securities portfolio in the near term.
Vietnam's bond settlement infrastructure at VSD and trading infrastructure at HNX would also need to be adapted to handle foreign investor participation in VND instruments at scale. Neither of those upgrades is currently scoped.
What This Means for Practitioners#
The PM's directive gives the MoF a political mandate to move on long-term infrastructure debt, but a mandate is not a product. For infrastructure investors and DCM practitioners, the practical read is:
- Watch the MoF's research output. The directive requires the ministry to report back, not to launch. The research phase will reveal whether the ministry gravitates toward a sandbox pilot, a direct sovereign issuance, or a guaranteed bond structure using a policy bank intermediary.
- The sandbox angle is real but legally unsettled. Decree 323 provides the authority; whether the MoF will use it for sovereign instruments rather than leaving it for fintech products is an open policy question. The Decree 323 governance framework provides the foundational reading.
- FX is the deal-breaker. Any foreign investor considering a 15-30 year VND instrument needs a credible hedging market for VND at those tenors. That market does not currently exist in Vietnam. Until it does, the investor universe is limited to those with natural VND liabilities — a small pool.
- The stablecoin proposal is worth monitoring, not acting on. It is an academic proposal at this stage. If Resolution 05/2025/QH15 licensing progresses and the MoF engages with digital bond issuance, the mechanism becomes live. That is likely a 2027-2028 story at earliest.
The infrastructure financing gap is real and the policy pressure to close it is mounting — the disbursement gap visible in HCMC's early capital formation record is the downstream consequence of the upstream bond market shortfall. The VIFC sandbox is an innovative proposed solution, but it requires legal confirmation, secondary market infrastructure, and FX risk management tools that do not yet exist. The PM's directive starts the clock; how fast the MoF moves will determine whether this becomes a 2027 pilot or a 2030 aspiration.
