Inflation-Linked or Fixed Rate: Which Protects Real Returns
What you actually know on day one with each rate type
You know the indexation formula and reference index. Some structures adjust interest rates; others adjust principal while retaining a fixed coupon rate. Future nominal receipts depend on index changes.
A fixed-rate peer-to-peer (P2P) loan claim specifies its rate and schedule. Receipts depend on borrower performance; purchasing power depends on future prices.
The inflation linked bonds vs fixed rate comparison concerns nominal certainty versus inflation adjustment, without establishing positive real yield.
What changes over the term of each instrument
Indexation follows contractual rules. Lags, floors and caps affect tracking; your spending basket may differ from the reference index.
A fixed-rate claim has no automatic price adjustment. Its rate stays unchanged while the purchasing power of amounts due varies.
A shorter term shortens exposure to uncertain future inflation. Reinvestment starts a new exposure.
How real return behaves when inflation rises or falls
Full indexation can stabilize the contractual real outcome against its reference index, assuming payments arrive and inflation passes through effectively. This does not establish every investor’s net result.
Does a fixed interest rate protect against inflation?
No. Rising inflation reduces a fixed return’s purchasing power; falling inflation increases it. Realized nominal return below inflation means a negative real result. Missed payments can also reduce actual returns.
What happens to real return on an inflation-linked instrument when inflation falls?
With ideal full indexation, nominal growth falls while the real component remains unchanged. Actual outcomes depend on adjustment rules, purchase price, taxes and costs; no universal real-return corridor applies.
How to calculate real return from a nominal rate
Real return vs nominal return distinguishes purchasing-power change from growth in money. Adjust nominal growth for inflation over the same period.
Subtract inflation from nominal return for an approximation. For an exact single-period result, divide one plus nominal return by one plus inflation, then subtract one, using decimal percentages.
For how to calculate real return, consider 6% growth and 4% inflation: approximately 2% real return, or about 1.92% exactly.
Assume one year, a fixed nominal return of 6%, ideal indexation maintaining 1% gross real return, and a hypothetical 4% inflation baseline. Assume repayment without costs, taxes, adjustment lags or early sales.
| Inflation scenario | Fixed-rate result | Ideal inflation-linked result |
|---|---|---|
| Above the assumed baseline: 7% | Nominal 6%; exact real return about −0.93%. | Nominal 8.07%; real return 1%. |
| At the assumed baseline: 4% | Nominal 6%; exact real return about 1.92%. | Nominal 5.04%; real return 1%. |
| Below the assumed baseline: 2% | Nominal 6%; exact real return about 3.92%. | Nominal 3.02%; real return 1%. |
These invented figures illustrate mechanics, not forecasts or promises. Indexed nominal growth includes the assumed real component.
What an early exit changes for each rate type
Rate structure does not determine exit rights. Marketable inflation-linked instruments can sell at changing prices; others have product-specific redemption conditions. Check these separately from indexation.
For an eligible Maclear claim, early exit requires a Secondary Market transfer to another investor. Listings are at par, meaning face value, or at a discount of up to 50%. Buyer demand, eligibility rules and fees affect the outcome; neither price nor execution time is assured.
Maclear’s main metric is Annualized Return on Investment (AROI): AROI = (Expected Earnings / Remaining Period) × (365 / Principal Purchased). Remaining Period is in days. This projection neither adjusts for inflation nor confirms payment.
Comparing the two without assuming either beats inflation
How do I compare a floating and a fixed rate honestly?
Convert comparable returns over the same period. A floating rate linked to another benchmark need not track inflation. Account separately for costs, taxes, payment timing and credit exposure.
| Comparison | Inflation-linked instrument | Fixed-rate loan claim |
|---|---|---|
| What is known on day one | Indexation formula; future nominal amounts are not fully fixed. | Contractual nominal rate; future purchasing power unknown. |
| What changes during the term | Indexed rate, principal or payments adjust under the rules. | Contractual rate unchanged; purchasing power varies. |
| How real return behaves if inflation rises | Comparatively stable in the ideal fully indexed case; terms and costs matter. | Falls for an unchanged realized nominal return; can turn negative. |
| How real return behaves if inflation falls | Same real component in the ideal case; nominal growth falls. | Rises for an unchanged realized nominal return. |
| Who is the debtor | Depends on the instrument; indexation does not identify or replace the debtor. | Business borrower, typically a small business repaying from operating cash flow. |
| What happens on early exit | Instrument-specific sale or redemption terms; indexation does not assure an exit price. | Eligible Maclear Secondary Market sale at par or at discount; no assured price or timing. |

Inflation protection investments address purchasing power, without removing credit risk or themselves providing a credit-risk premium. Maclear’s Provision Fund is a pooled platform reserve, not a buyback guarantee or deposit insurance. Principal is not protected against loss. Maclear AG is a non-banking financial intermediary under Swiss regulation and belongs to PolyReg, a self-regulatory organization (SRO).
Neither an inflation-linked rate nor a fixed rate guarantees a positive real return - indexation addresses purchasing-power loss under its terms but not borrower credit risk; a fixed rate provides no automatic inflation adjustment and does not protect against borrower default.
Frequently asked questions
Does p2p lending beat inflation?
Not necessarily: the realized nominal return must exceed inflation over the same period for the gross real result to be positive. Missed payments, losses, costs and taxes can reduce the outcome further. Neither a platform label nor a fixed contractual rate establishes inflation protection; indexation also leaves credit risk and product-specific conditions to assess.
What is the difference between real return and nominal return?
Nominal return measures investment growth in money; real return measures that growth after adjusting for inflation. Use the same period. Subtraction approximates the exact adjustment of nominal growth for price growth. Real return indicates the change in purchasing power, rather than just the account amount.
How do I calculate real return from a nominal rate?
Subtract inflation over the same period for an approximation. For an exact single-period result, divide one plus nominal return by one plus inflation, then subtract one, using decimal percentages. Match periods and distinguish a contractual rate from realized investment growth. A quoted annual rate cannot simply be compared with inflation from an unrelated period.
Does a fixed interest rate protect my money from inflation?
No: it fixes nominal terms rather than purchasing power. Real return depends on inflation over the holding period and the payments actually received. Lower inflation improves the real value of an unchanged nominal return; higher inflation reduces it. A shorter term limits the exposure window but does not guarantee a positive real outcome.
What happens to an inflation-linked instrument if inflation drops sharply?
Its inflation adjustment generally declines under the contract, reducing nominal growth relative to a higher-inflation scenario. In the ideal fully indexed case, the real component remains unchanged rather than increasing. Actual outcomes depend on adjustment rules, floors, costs, taxes, purchase price and payment performance. Falling inflation is also different from outright deflation, when prices decline.
