Argentina enacts RIGI — 30-year regulatory-stability incentive regime for large investments (Law 27.742)

Mechanism

RIGI is structurally a self-selecting incentive regime: rather than allocating subsidies through discretionary tenders, it offers any qualifying investor that commits ≥USD 200M to a single-purpose vehicle (VPU) a contractual lock-in of tax, customs, FX and regulatory treatment for 30 years. The mechanism is closer to a bilateral investment treaty than to a US-IRA-style tax-credit programme.

Key features that drive investor behaviour:

• 30-year stability clause. RIGI projects are insulated from future

legislative or regulatory changes that worsen their fiscal position. This is the single most important feature given Argentina's history of policy volatility and capital controls.

• Corporate tax 25% (vs. 35%). Sub-OECD effective rate for very large

capital-intensive projects.

• Customs exemption. No import duties or statistical fees on capital

goods, spare parts, inputs, or consumables required for the project.

• FX repatriation phase-out. A direct response to the cepo cambiario.

Year 1: 20% of export proceeds free of repatriation requirement. Year 2: 40%. Year 3+: 100%.

• International arbitration. ICSID or UNCITRAL — protects against

Argentine-court risk.

Downstream implications

• Lithium Triangle re-rates. RIGI plus a tightening DRC-cobalt regime

(2025-02-22-drc-arecoms-cobalt-export-ban-quota-system) shifts marginal battery-mineral capex toward Argentina at the expense of Chile (where the 2023 National Lithium Strategy mandates state-majority JVs) and Bolivia (no investable framework). Watch first-quartile cost-curve names: Rio Tinto Rincón, Ganfeng's Cauchari-Olaroz, POSCO's Sal de Oro, Lithium Argentina–Ganfeng JV, Eramet/Tsingshan Centenario-Ratones.

• LNG / Vaca Muerta acceleration. YPF + Petronas + ENI + Shell

consortium projects can pencil USD 30B+ over a decade if RIGI holds. This is the most credible non-US LNG growth story for the late-2020s.

• Bilateral framework competition. RIGI undercuts Brazil's BNDES-led

industrial policy and Mexico's Plan México for large multinational capex. Argentina also moves out of the EM-resource-nationalism cluster (Indonesia, DRC, Zimbabwe) and into an attract-rather-than-capture posture.

• Political-risk asymmetry. A change of government before 2027 mid-terms

could attempt to repeal RIGI, but the 30-year contractual lock-in plus ICSID forum selection make repudiation costly. The arbitral-award track record on Argentine sovereign disputes (YPF, Repsol, etc.) is the reference case.

Open questions

• Does the 30-year stability clause survive a Peronist return to power?

Argentine arbitration history suggests yes, at the cost of award liabilities.

• Will Mexico, Brazil, or Colombia replicate the framework? Plan México

(2025-01-21) is closest in spirit but uses sectoral decrees rather than a single statutory regime.

• How quickly does the project pipeline convert? USD 17.9B remained "under

review" as of mid-2025 — the conversion rate from submission to approval is the single best forward indicator of the regime's traction.

• Does RIGI plus FX-control liberalisation (April 2025) produce a sustained

re-rating of Argentine equities (ARGT) and sovereign credit, or does inflation/fiscal slippage abort the cycle as in 2018-2019?
