5 Questions to Ask When Someone Promises 'Guaranteed' Returns: A Guide for UAE Investors

The short answer: no investment return is truly guaranteed. A guarantee is a promise made by a specific legal entity, and it is only as reliable as that entity’s balance sheet on the day you need it. The useful question is never “is it guaranteed?” but “who is guaranteeing it, and what are they doing with my money to afford the promise?” This guide sets out five questions that answer that, the patterns that usually sit behind the word, and the cases where guarantees failed.

What “guaranteed” actually means

People who have built wealth through years of work want, above all, to keep it. That is exactly why “guaranteed returns” and “principal protection” are such effective sales language. But even cash is not guaranteed in the absolute sense. Bank deposits are protected only up to a statutory ceiling, and banks do fail: Lehman Brothers collapsed and Northern Rock was nationalised in 2008; in 2023 SVB failed and Credit Suisse was absorbed by UBS in an emergency takeover. When you accept a guaranteed return, you are lending to a corporate entity that takes on a project risk and pays you a fixed amount, betting that the project earns more than it owes you. The guarantee transfers the risk to that entity. It does not remove it.

The one number that anchors everything

There is a benchmark for what certainty costs: the risk-free rate, what the safest borrower in the world pays to hold your money for a few months. In mid-2026 a three-month US Treasury bill yields about 3.6% (US Federal Reserve, H.15). Because the dirham is pegged to the US dollar, that is also the right reference point for a UAE investor holding AED or USD.

Anything offering materially more than the risk-free rate with certainty has to explain where the extra return comes from, if not from extra risk. The US Securities and Exchange Commission puts it bluntly:

If you come across an investment program that promises high returns with little or no risk, be aware that it is likely a fraud.

US SEC, Investor.gov

There is a structural reason too. If a riskless, above-market return existed, sophisticated capital would borrow without limit to capture it until the opportunity disappeared. That is the no-arbitrage principle underpinning modern markets (CFA Institute). A genuine, riskless 17% does not survive contact with a functioning market. Either it is not riskless, or it is not 17%.

The five questions to ask

1. Who is the guarantor, and what happens if they fail?

A guarantee is a claim on a balance sheet, so name the balance sheet. A structured note is, in the SEC’s words, an unsecured debt obligation of the issuer: if the issuer fails, you are a creditor in the queue (SEC investor alert on structured notes). Investors who bought “100% principal-protected” notes issued by Lehman Brothers discovered in 2008 that the protection ended with the issuer. A US regulator later fined a major distributor $2.5m and ordered $8.25m in restitution for selling those notes without making the credit risk clear (FINRA).

Ask what happens if the institution ceases to exist: is there collateral held separately in your name, insurance from an unrelated party, or nothing at all? Has anyone independent audited the guarantor’s financial statements, and can you see them?

2. Who regulates the entity making the promise?

A recognised regulator, such as the Financial Services Regulatory Authority in Abu Dhabi Global Market or the Dubai Financial Services Authority in the Dubai International Financial Centre, means the firm operates under conduct rules, capital requirements and a complaints process. Check the public register yourself rather than trusting a licence number in a brochure: the FSRA, DFSA and SCA each publish one. In 2025 the FSRA warned about a fake Telegram channel impersonating the regulator itself and promising guaranteed returns (ADGM FSRA), so verify through the regulator’s own website, not a link someone sends you.

3. How far above the risk-free rate is this, and why?

This is the logic test. If Company A guarantees 18% while Company B, of similar standing, raises billions by promising 10%, why does Company A need to pay 18%? Either the underlying project is far riskier than disclosed, or the “return” is being paid out of new investors’ capital, which is the defining feature of a Ponzi scheme. Ask what activity generates the return, in plain terms, and whether that activity could plausibly produce it after the issuer’s own costs and profit.

4. Is there borrowing or leverage anywhere in the structure?

Leverage is what turns a modest yield into a double-digit headline, and a modest setback into a total loss. Put up $20 of your own money, borrow $80, and you control a $100 position. A 20% fall, an unremarkable market move, erases your entire stake before a single fee or interest payment. The SEC’s guidance on margin is explicit: you can lose more than you invested, and the lender can sell your holdings to cover a shortfall without notifying you first (SEC). If there is leverage, model a 20% adverse move before you sign.

5. What does it cost to get out, and who is paid if you buy?

Even when a return is honoured, the terms decide what you keep. Read for these:

• Surrender penalties. Many savings and annuity-style products charge to exit for the first several years, sometimes enough to wipe out early contributions (Investor.gov).
• Layered fees. Establishment charges, fund fees, insurance charges and commissions stack up and reduce value regardless of performance. Understanding how your advisor is actually paid matters as much as the headline rate.
• Caps and participation rates. “Index-linked” products often pay only a fraction of the gain, such as a 7% cap in a 12% year, while a “guaranteed minimum” applies only if the issuer stays solvent (FINRA).
• Illiquidity. If you cannot get your money out at par when you need it, the headline rate is theoretical.
• Nominal versus real. A guaranteed 3% when inflation runs higher is a guaranteed loss of purchasing power (Investor.gov).

Commission is not a sin, but it should be disclosed and understood before you commit.

A worked example: the “17% guaranteed” FCNR scheme

If you hold an Indian passport and a bank relationship in the Gulf, a particular pitch may have reached you: place savings in a Foreign Currency Non-Resident (FCNR) deposit, borrow against it, and earn a “guaranteed 17%.” It was the subject of an Economic Times piece, and it recirculated after the Reserve Bank of India reopened a concessional swap window for FCNR(B) deposits in mid-2026.

The mechanic, stripped of marketing: an investor places $1m in an FCNR deposit yielding around 6.5%. A bank lends roughly seven times that, $7m, at a lower foreign-currency rate of around 5%. The deposit earns about $520k; the borrowing costs about $385k; the roughly $135k difference, divided by the investor’s own $1m, reads as a ~17% return (Deccan Chronicle). India’s own research desks flagged that the spread was near a multi-year low and that the arithmetic ignores floating rates, fees, taxes and forced unwinds (Value Research).

The guarantee attaches to the deposit. The return attaches to the leverage. Run it through the five questions and it fails the fourth immediately.

It has happened before, on every continent

The same promise, in local clothing, has separated savers from their money for decades. Four episodes, each documented by the regulators who cleaned them up:

The minibond cases were resolved by the HKMA and the Monetary Authority of Singapore; Madoff and Stanford by the SEC and the US Department of Justice; and London Capital & Finance by the FCA, followed by a government compensation scheme.

The Gulf has its own versions

• “Savings plans.” After complaints about expensive, locked-in long-term policies, the UAE capped insurance commissions and introduced a 30-day free-look refund window in 2020 (Gulf News). Many were sold as “savings” with surrender penalties that could erase early contributions.
• Guaranteed rental yields. Dubai developers have used multi-year “guaranteed” rental returns of 7% and above to move stock; analysts flagged the strain on developer finances and questions of enforceability (Gulf News).
• Outright scams. UAE authorities have repeatedly warned against schemes offering fixed monthly returns “with no risk”, which describes a pyramid rather than an investment.

Most savings plans and many structured notes are legal. The point is that “guaranteed” and “no risk” are doing work the underlying product cannot.

A note on government guarantees

Governments borrow to fund public spending, and their guarantees deserve two separate checks.

Capacity to repay. The US government issues the currency it borrows in, so for someone who holds and intends to keep holding dollars, US Treasury lending is the most secure form of lending available. Its real value still depends on the dollar’s purchasing power. When another government borrows, its ability to repay has to be assessed on its own merits; the Greek debt crisis is a reminder that sovereign defaults happen.

Currency mismatch. When a government borrows in US dollars but collects tax and project revenue in its own currency, every fall in that currency raises the real burden of the debt. Egypt and Turkey have both borrowed heavily in dollars while their pounds and lira lost substantial value, which is exactly the situation in which a sovereign guarantee becomes harder to honour.

The bottom line

Markets pay you for bearing risk. A return that is genuinely certain and genuinely high would be arbitraged away before it reached your inbox, so when “guaranteed” and “high return” appear in the same sentence, the honest reading is that a risk has been relabelled, leveraged or buried in the terms.

Real, low-risk return tracks the risk-free rate, which is the logic behind a transparent cash product like SmartCash: the rate is the rate, with no teaser, no lock-in and no leverage presented as a guarantee. For anything beyond cash, ask the five questions, read the fine print, and have someone independent review the terms. A conversation with a fiduciary advisor who is not paid to sell you the product costs nothing, and you can book one here.
