In short
With an RSA Retail Savings Bond you lend to the South African government — the strongest domestic credit there is, at a rate set by National Treasury. With private lending you lend into a structured, usually secured private arrangement, typically for more. Both make you a lender for a term; they differ in who borrows from you, and the return reflects that difference.

01 — The short version
The short version
These two are more alike than most comparisons on this site: in both, you are a lender earning a return over a term, not an owner exposed to a market. The real question is who you're lending to. Lend to the government and you take on about as little credit risk as is domestically possible, at a rate Treasury decides. Lend into a well-structured private arrangement and you take on more credit risk, secured against assets, for a higher return.
So this isn't a safety-versus-danger choice. It's a step along the same ladder: same activity, different borrower, different reward.
02 — How each works
How each one works
RSA Retail Savings Bonds are issued by National Treasury directly to the public. You invest a minimum amount for a set term and earn interest at a rate Treasury publishes — available in fixed-rate, inflation-linked and top-up variants. Because the borrower is the state, the credit standing behind it is the strongest available locally. They're designed to be held to maturity, with early withdrawal possible in defined circumstances and typically penalised.
Private lending places your capital into a lending arrangement with a private borrower, administered by a registered credit provider. Local arrangements are usually prime-linked and typically secured against assets — that security being what stands in for the government's backing. The capital is committed for the term.
03 — Side by side
Side by side
| RSA Retail Savings Bond | Private lending | |
|---|---|---|
| Who borrows from you | The SA government | A private borrower |
| What backs it | The state | Security over assets |
| Rate set by | National Treasury | The arrangement; prime-linked |
| Typical return | Lower | Higher |
| Access | Held to maturity; early exit penalised | Committed for the term |
| Credit risk | Very low | Real, but secured |
The pattern is clean: the government pays less because it's the safest borrower; private lending pays more because you're accepting credit risk that security is designed to mitigate.
04 — Returns
Returns compared
Retail bond rates are published by National Treasury and vary by term and bond type — and they move over time with prevailing rates, so the current figures should always be checked at source rather than assumed. What's consistent is the principle: because the state is the borrower, the rate sits at the conservative end.
Private lending sits higher. Local arrangements are commonly quoted around prime + 1% to prime + 5% — with prime at 10.5% (August 2026), roughly 11.5% to 15.5% a year. That premium isn't free money: it's compensation for lending to a private borrower rather than the state. The right way to read the gap is as the price of the extra credit risk — which is exactly why how an arrangement is secured deserves your attention.
The inflation-linked variant deserves a mention of its own, because it answers a different question. Rather than paying a set rate, it adjusts your capital in line with inflation and pays interest on top — so its job is protecting buying power rather than maximising return. If your worry is that money quietly loses value over a decade, that's a genuinely useful instrument, and it isn't really competing with private lending at all.
A prime-linked private-lending return responds to inflation differently: it doesn't track inflation directly, but because the Reserve Bank raises rates when inflation runs hot, prime tends to climb in the same conditions — so the return moves in the right direction, indirectly, rather than by design.
05 — Security & access
Security and access compared
On credit risk, retail bonds are the stronger instrument, and it's only honest to say so plainly: government backing is about as robust as domestic credit gets. Private-lending capital isn't guaranteed; it relies on the arrangement, its security and the provider running it. That's the trade for the higher return.
On access, the two are closer than people expect. Both are term commitments: retail bonds are meant to be held to maturity, with early withdrawal restricted and typically penalised; private lending commits capital for its term. Neither is a place for money you might need next month — so if liquidity is the deciding factor, the real answer is probably a money market fund rather than either of these.
Same activity, different borrower. The government pays you less precisely because it's the safest borrower in the country.
06 — Which suits you
Which suits you — and using both
Lean to retail bonds for the portion of capital where you want the least possible credit risk and are content with a conservative return — and where the inflation-linked variant is genuinely useful if protecting buying power is the goal. Lean to private lending for capital you can commit for a term and where you want a materially higher return, and you're comfortable with a secured private arrangement rather than state backing.
Plenty of people hold both, and it's a sensible structure: retail bonds as the ultra-conservative rung, private lending as the higher-yielding rung above it, and cash in a money market fund below both for anything that might be needed soon. Thought of as a ladder rather than a contest, each rung has an obvious job.
One practical point in retail bonds' favour is how easy they are to access: you deal with National Treasury directly, minimums are modest, and there's no intermediary to assess. Private lending involves more upfront work — understanding the arrangement, the security and the provider — which is precisely why the questions on this site matter. That's not a strike against it; it's simply the difference between lending to the state, where the credit assessment is effectively made for you, and lending privately, where part of the return is earned by understanding what you're lending into.
