A retirement annuity is the most personal product in halal finance: it is your money, your name, your 27.5% tax deduction, and a multi-decade relationship with one provider's governance. South Africa offers three genuinely distinct Shariah RA philosophies. All three work. They optimise for different things, and the differences compound over thirty years.

The three contenders, briefly

  • Oasis Crescent Retirement Annuity Fund: the purist's choice. An FSCA-registered Shariah RA where the wrapper, administrator (Oasis Crescent Retirement Solutions), investment manager and scholars are all Shariah-native. Minimum R500 a month; balanced Regulation 28 mandate across the Oasis Crescent range; compliance certified by Shaykh Nedham Yaqoobi, Shaykh Yusuf Talal DeLorenzo and Dr Mohd Daud Bakar, with signed confirmations published.
  • 27four Shariah RA and preservation funds: the diversifier's choice. Prescient-administered wrappers holding the multi-managed 27four Shariah range, so the retirement pot is spread across underlying Islamic managers rather than betting on one house's stock picking.
  • Sygnia RA with the Islamic Balanced Fund: the cost-cutter's choice. A cheap platform RA (R500 monthly debit order or R20,000 lump sum, free transfers in, monthly Regulation 28 monitoring) holding Sygnia's AAOIFI-screened Islamic Balanced Fund, running since December 2010, with Camissa Islamic Balanced, Camissa Islamic High Yield and the 27four Shariah Balanced FoF also on the platform menu.

Round one: Shariah governance

Oasis wins, and not narrowly. Its scholar bench is world famous, its compliance confirmations are signed and published, and purification runs at fund level across the range. Sygnia makes the most specific standards commitment among mainstream managers (AAOIFI, per its fact sheets) but names no scholars and posts no certificates. 27four's compliance operates at portfolio level with underlying managers' boards underneath, and no published group scholar roster, the recurring critique of an otherwise strong house. If visible, verifiable scholar accountability is your first criterion, this round decides the whole contest.

Round two: cost

Sygnia wins on structure. A low-cost platform plus a flat-fee balanced fund is the cheapest architecture on offer; Oasis runs performance-linked management fees disclosed in application forms rather than a published table, and multi-manager structures like 27four's inherently layer fees (wrapper plus multi-manager plus underlying managers). The honest caveat: none of the three publishes a simple public all-in number, so the only fair comparison is requesting the effective annual cost (EAC) for your actual contribution level from each. Do it in writing; over thirty years, one percentage point of cost difference consumes roughly a fifth of the final pot.

Round three: investment architecture

This depends on your theory of risk. One-house conviction: Oasis, where the closed menu is the point, everything certified under one roof, with the group's 1998-vintage equity record underneath. Manager diversification: 27four, the only structure where no single Islamic manager's bad decade can dominate your outcome. Flexibility: Sygnia, the only wrapper of the three where you can blend managers yourself, holding its Islamic Balanced alongside Camissa and 27four funds in one RA and adjusting as evidence accumulates. For investors who expect to have opinions over the decades, that platform flexibility is worth real money.

Round four: the endgame

RAs end at compulsory annuitisation, and here the field narrows brutally: only Oasis and 27four own compliant post-retirement products (the Crescent Pension Annuity and the 27four Life living annuity). A Sygnia RA saver must transfer at retirement, which is administratively fine but worth knowing on day one. Oasis and 27four offer the complete lifecycle in-house; the living annuity guide covers the destination in detail.

The verdict, by saver

  • Maximum assurance, one certified roof, lifecycle completeness: Oasis Crescent. Pay for it knowingly.
  • Diversification across managers, employer and umbrella needs, risk-graded drawdown later: 27four, with the EAC quote and the Shariah certification obtained in writing first.
  • Lowest cost, manager choice inside the wrapper, comfort with fund-level rather than scholar-level assurance: Sygnia, transferring at retirement.
  • Whoever you pick: automate the debit order, claim the deduction every year, and revisit the choice at most annually.

There is no wrong answer here, which is itself remarkable: a decade ago this comparison barely existed. Full provider grades on the Halal Money Index, full product data on the retirement page.

Quick answers

What is the cheapest way to run a Shariah RA?

Structurally, Sygnia: a low-cost platform plus a flat-fee AAOIFI-screened balanced fund, from R500 a month, with no performance fees anywhere in the chain. But since none of the three publishes a simple all-in number, the only real comparison is requesting the effective annual cost from each for your actual contribution level.

Can I switch providers later?

Yes, RA transfers between approved funds are standard and Sygnia accepts them free. Fees and exit terms vary, so check before assuming. The bigger switching moment is retirement itself: Sygnia savers must transfer to Oasis or 27four for compliant drawdown, while those two houses carry members through in-house.

Do all three qualify for the tax deduction?

Fully. Contributions to any approved retirement annuity fund are deductible up to 27.5% of the greater of taxable income or remuneration, capped at R350,000 a year, whether the underlying portfolios are Shariah or conventional. The compliance choice costs none of the tax break.
