CMVM's Conta Poupança-Investimento Proposal Sketches a Portuguese Retail Investor Vehicle Against the UK ISA, French PEA and Italian PIR Reference Set — How Laginha's Architecture Stacks Up

The proposal that CMVM (Comissão do Mercado de Valores Mobiliários, Securities Market Commission) Chair Luís Laginha de Sousa surfaced at the regulator's 35th-anniversary conference on 31 May 2026 — the Conta Poupança-Investimento (CPI, Savings-Investment Account) — sits in the early-architecture stage of a project that would graft a Portuguese retail-investor vehicle onto a European reference set led by the UK Individual Savings Account (ISA), the French Plan d'Épargne en Actions (PEA), the Italian Piano Individuale di Risparmio (PIR), the Swedish Investeringssparkonto (ISK) and the Polish Indywidualne Konto Emerytalne (IKE). The Portuguese architecture, as Laginha framed it in the 31 May conference closing remarks, would carry a long-term-savings tax-deferral or tax-exemption envelope, a domestic-equity tilt designed to mobilise household savings toward the Lisbon stock-exchange capital-formation pipeline, and a regulated product perimeter administered through banks, corretoras (brokers), and sociedades gestoras (management companies) authorised by the CMVM and supervised under the Banco de Portugal prudential perimeter.

The European reference set: where the CPI lines up

The principal European retail-investor savings vehicles inform the CPI design space across five architectural dimensions: the annual contribution ceiling, the eligible-instrument perimeter, the tax-treatment envelope, the holding-period anchor, and the geographic-tilt mechanism. The UK ISA system (Individual Savings Account, introduced 1999 under the Finance Act 1998, with the stocks-and-shares variant carrying a £20,000 annual contribution ceiling for the 2025/26 tax year) is the largest comparable, with capital-gains and dividend-income tax exemption inside the wrapper. The French PEA (Plan d'Épargne en Actions, introduced 1992, with the headline PEA carrying a €150,000 contribution ceiling and a five-year holding requirement to unlock the tax exemption on capital gains and dividends, leaving social contributions at 17.2%) carries the strongest geographic-tilt mechanism, with eligible-instrument restrictions to EU and EEA-domiciled equities, UCITS funds with a minimum 75% EU-equity exposure, and PEA-PME-ETI (PEA Petites et Moyennes Entreprises - Entreprises de Taille Intermédiaire, the SME variant) for the small-and-mid-cap tilt.

The Italian PIR (Piano Individuale di Risparmio, introduced under the 2017 Legge di Bilancio with substantial 2023 reform, carrying an annual contribution ceiling of €40,000 and a lifetime cap of €200,000) explicitly anchors the Italian small-cap geographic tilt — at least 70% of the portfolio must be allocated to securities issued by Italian or EU/EEA-with-Italian-permanent-establishment companies, and at least 25% of that 70% must be allocated to companies outside the FTSE MIB index. The Swedish ISK (Investeringssparkonto, introduced 2012) operates on a flat-rate notional-yield taxation framework rather than a tax-exemption envelope — the account is taxed annually on a deemed return calculated at the government borrowing rate plus 1 percentage point, with a 0.375% floor and a 30% rate on the notional yield. The Polish IKE (Indywidualne Konto Emerytalne, introduced 2004) and the German Altersvorsorge-Wertpapier-Sparplan are pension-anchored variants with tax-exemption envelopes tied to retirement-age withdrawal triggers.

Where the Portuguese architecture currently sits: PPR, IRS Categoria E and the OICVM regime

The Portuguese long-term-savings landscape carries three existing principal architectures. The Plano Poupança-Reforma (PPR, Retirement Savings Plan, Decreto-Lei n.º 158/2002 of 2 July with successive amendments) is the closest comparable to a pension-anchored ISA — capital and accrued income are taxed at 8% on withdrawal under the qualifying conditions (age 60 or retirement, illness, unemployment), with the contribution carrying a 20% IRS Categoria F deduction up to €400 a year for under-35 holders, €350 for 35-50 holders, and €300 for over-50 holders. The IRS Categoria E framework taxes interest and dividend income outside a wrapper at a 28% liberatory rate by default, with the option to aggregate (englobamento) into the progressive IRS schedule at the taxpayer's election. The OICVM (Organismos de Investimento Coletivo em Valores Mobiliários, UCITS) regime under the Regime Geral dos Organismos de Investimento Coletivo (Lei n.º 16/2015 of 24 February with substantial 2024 reform) provides the principal collective-investment-vehicle architecture for fund-based exposure.

The CPI proposal would sit alongside the PPR rather than substitute for it — Laginha's framing at the 31 May conference treated the CPI as a more flexible, less retirement-anchored vehicle with a wider eligible-instrument perimeter and a shorter holding-period anchor than the PPR's age-60 / qualifying-event triggers. The principal design questions left open in the 31 May framing are (i) the annual contribution ceiling, (ii) the tax-treatment envelope (full exemption, tax-deferral, or notional-yield), (iii) the eligible-instrument perimeter (Portuguese equities only, Euronext Lisbon-listed, EU/EEA-domiciled, or a wider perimeter), (iv) the holding-period anchor required to unlock the tax envelope, and (v) the geographic-tilt mechanism — whether the CPI carries an explicit Portuguese-equity tilt analogous to the PIR's Italian-equity 70% / non-FTSE MIB 25% architecture, or whether it would default to a broader EU/EEA perimeter analogous to the French PEA.

The Lisbon capital-markets context: why the CPI now

The CPI surfaces against a specific Lisbon capital-markets backdrop. The Parpública 19-holding disposal window, opened 30 May 2026 at the CMVM 35th-anniversary conference, frames a state-sector rotation toward listed-equity exits. The CUF €32 million dividend distribution (CMVM filing 26 May 2026), the BCP €407.46 million recompra de ações (share-buyback) authorisation (CMVM filing 27 May 2026 for the 4 June to 4 December 2026 window), the Vista Alegre €1.07 euros-per-share OPA (Oferta Pública de Aquisição, public offer) close-out and the broader PSI weekly close at 9,093.82 on Friday 13 June 2026 (+2.6% for the week) form a market environment in which the principal Lisbon-listed names are returning cash to shareholders, the IPO pipeline is thin, and the domestic retail-investor pool — historically tilted toward bank-deposit and Certificados de Aforro / Certificados do Tesouro savings vehicles — has limited direct equity exposure.

The IGCP (Instituto de Gestão da Tesouraria e do Crédito Público, Treasury and Public Debt Management Agency) Certificados de Aforro Série F and the Certificados do Tesouro Poupança Valor architectures sit as the principal household-savings benchmark on the public-debt side. The June 2026 Certificados de Aforro Série F net subscription tape continues to dominate the household-savings flow, with the headline 2.5% base rate at the May 2026 reset point sitting close to but below the Lisbon-listed dividend-yield mean for the PSI's principal heavyweights. The CMVM Laginha proposal is, in part, an architectural answer to the question of why Portuguese household-savings flow is so heavily concentrated in IGCP retail-debt vehicles when the Lisbon equity market would benefit from broader domestic-retail capital inflow.

The CMVM regulatory architecture: where the CPI would live

The CMVM regulatory architecture (Decreto-Lei n.º 142/2025 of 20 June revising the Código dos Valores Mobiliários, Código dos Valores Mobiliários CVM) sets the supervisory perimeter inside which the CPI would operate. The CVM Article 289.º-A regime on the comercialização (marketing) of financial instruments, the Article 290.º on Tipos de Atividades de Intermediação Financeira (Types of Financial Intermediation Activities) and the Article 290.º-A on Adequação (Suitability) under MiFID II / MiFIR transposition (Diretiva 2014/65/UE and Regulamento (UE) 600/2014, with the MiFID II revision under Diretiva (UE) 2024/790) form the conduct-of-business framework. The Banco de Portugal prudential perimeter (Regime Geral das Instituições de Crédito e Sociedades Financeiras, RGICSF, Decreto-Lei n.º 298/92 of 31 December with successive amendments) handles the depositary-credit-institution side of the CPI distribution.

The product approval and disclosure architecture under the PRIIPs Regulation (Regulamento (UE) 1286/2014 on Packaged Retail and Insurance-based Investment Products, with the Documento de Informação Fundamental, DIF as the principal disclosure instrument) would be load-bearing for the CPI launch — the DIF would need to capture the tax-envelope features, the eligible-instrument perimeter, the holding-period anchor, and the geographic-tilt mechanism. The DMIF II / MiFID II Suitability Assessment (Avaliação de Adequação) and the Appropriateness Assessment (Avaliação de Adequação ao Cliente Não Profissional) would frame the distribution conduct standards.

The five operational design questions

The 31 May conference framing left five principal design questions open:

• Annual contribution ceiling: the European reference set ranges from the PIR €40,000 annual / €200,000 lifetime to the UK ISA £20,000 (around €23,500) annual to the PEA €150,000 lifetime cap. A Portuguese CPI ceiling in the €15,000-€25,000 annual range would line up with the European medium and signal a serious-but-modest retail-savings vehicle.
• Tax-treatment envelope: the principal options are (i) full tax exemption on capital gains and dividends inside the wrapper (ISA / PEA model), (ii) tax-deferral with a reduced rate on withdrawal (PPR-style 8% on age-60 / qualifying-event withdrawal), or (iii) annual notional-yield taxation (Swedish ISK model). The Laginha 31 May framing leaned toward the first model — full exemption on qualifying conditions — but did not commit.
• Eligible-instrument perimeter: the principal options are (i) Euronext Lisbon-listed equities only (the narrowest, with strongest geographic tilt), (ii) EU/EEA-domiciled equities and UCITS funds (the PEA model), or (iii) a wider perimeter including non-EU equities and ETFs (the ISA model). The Lisbon capital-formation argument leans toward the narrower perimeter, but distribution and customer-experience arguments lean toward the wider perimeter.
• Holding-period anchor: the principal options are (i) no minimum (ISA), (ii) five-year minimum to unlock the tax envelope (PEA), or (iii) longer lock-up (PIR five years, PPR eight years). A five-year anchor would line up with both PEA and PIR.
• Geographic-tilt mechanism: the principal options are (i) no geographic tilt (ISA), (ii) EU/EEA-default with no internal sub-tilt (PEA), or (iii) explicit domestic-equity tilt analogous to PIR's 70% Italian-equity / 25% non-FTSE MIB sub-tilt. The Lisbon capital-formation argument would push toward the third model, with potentially a 60-70% Portuguese-listed-equity tilt and a sub-tilt toward the non-PSI principal-names segment.

What this means in practice for residents and expat investors

The CPI is still at the proposal stage — the institutional architecture is sketched at the CMVM 35th-anniversary conference and would need to move through the Ministério das Finanças technical-working-group stage, the Assembleia da República legislative-pipeline cycle and the European Commission state-aid notification (if the tax envelope is treated as state aid under Article 107.º Tratado sobre o Funcionamento da União Europeia) before it crystallises into a launch architecture. The realistic timeline is the 2027 OE2027 / OE2028 cycle, with potential operationalisation across 2027-2028.

Six practical implications for residents and expat investors tracking the file:

• (a) PPR remains the principal current vehicle: the Plano Poupança-Reforma architecture under Decreto-Lei n.º 158/2002 remains the principal current tax-advantaged long-term-savings vehicle, with the 20% IRS Categoria F deduction up to €400 a year for under-35 holders. The CPI proposal does not displace the PPR; the two would sit alongside each other in the architecture.
• (b) IRS Categoria E options under the current regime: the 28% liberatory rate on interest and dividend income remains the default outside a wrapper; the englobamento option remains available at the taxpayer's election for those whose marginal IRS rate is below 28%.
• (c) Certificados de Aforro and Certificados do Tesouro remain the principal public-debt retail vehicles: the IGCP Série F Certificados de Aforro and the Certificados do Tesouro Poupança Valor architecture remain the principal public-debt retail-savings vehicles, with the May 2026 reset point and the 2.5% base rate the current operational reference.
• (d) Non-EU expats on the IFICI or IRS Jovem track: the CPI proposal as framed does not differentiate between EU and non-EU residents on the tax-envelope side, but the IFICI (Incentivo Fiscal à Investigação Científica e Inovação) and IRS Jovem Article 12.º-B regimes would interact with the CPI tax envelope at the IRS Modelo 3 filing stage. The IFICI 20%-flat-rate envelope on Categoria A income would not directly capture CPI gains, which would sit inside the Categoria E / G framework.
• (e) The Lisbon capital-markets pipeline matters: if the CPI launches with a domestic-equity tilt, the Lisbon-listed pipeline — including the Parpública 19-holding disposal window, potential post-2027 IPO activity, and the existing PSI principal-names dividend track — becomes the principal investable-universe anchor.
• (f) Distribution architecture and account-opening: the CPI distribution architecture would sit across banks (Caixa Geral de Depósitos, Millennium BCP, Santander Totta, Novobanco, BPI), corretoras (e.g., XTB, Activobank, Banco BiG, Best Banco) and sociedades gestoras de OICVM. The account-opening process would follow the standard MiFID II Suitability Assessment cycle and the AT (Autoridade Tributária) anti-money-laundering Know-Your-Customer (KYC) framework.

The principal operational waymarker is the Ministério das Finanças technical-working-group readout — typically the first sign that a CMVM proposal at this conceptual stage is moving into legislative drafting. The OE2027 Lei (proposed late 2026 with the statutory presentation around 15 October 2026) is the principal anchor for whether the CPI lands in the 2027 cycle. The next operational reference points are the CMVM Q3 2026 Activity Report, the Banco de Portugal Boletim Económico October 2026 read on household financial assets, and the European Commission Autumn 2026 Country-Specific Recommendation on Portuguese capital-markets development.
