Currency Risk in P2P Lending: What a 5% Swing Does to a 12% Yield

Nearly every retail P2P platform in Europe lends in euros, and nearly every article about P2P returns quietly assumes you live your financial life in euros too. If you do, you can skip the next two thousand words with a clear conscience: on a euro platform, a euro investor carries essentially no currency risk. But if your salary, rent and savings are in Swiss francs, pounds, zloty or kronor, the exchange rate is not a footnote. It is a second, unpriced position that sits on top of every loan you fund, and over a typical holding period it can take back a third of your advertised yield - or, occasionally, add to it. This guide walks through the arithmetic with real reference rates, shows where conversion costs hide on the platforms we track, including Maclear, which ranks #3 of the 44 platforms we cover at 8.4/10, and ends with the four practical ways to manage the risk without pretending you can hedge it away.

TL;DR

Almost all of the 19 platforms in our main coverage lend and pay interest in euros. A euro-based investor carries no FX risk; a CHF, GBP, PLN or SEK investor carries it on every single loan.
The arithmetic is unforgiving: a 12% euro yield with a 5% adverse currency move over the year nets out near 6.4% in your home currency - before tax and conversion fees.
You pay currency costs even when the rate never moves: converting in and out through a bank typically costs a spread each way, and some platforms also charge their own exchange fees - at Mintos, currency exchange sits inside a fee line worth around EUR 1.4M of 2024 revenue [source: Mintos annual accounts, via our dossier].
Currency risk also exists at the operator level: Maclear lends in euros but is a Swiss company reporting in francs, so its own FY2024 accounts carry the EUR/CHF mismatch - a structural detail most reviews skip.
The honest fixes are boring: invest from the currency you will spend in, treat FX as part of your return calculation (your XIRR should be run in your home currency), and keep conversion costs under 0.5% per round trip.

The two layers of currency risk

When people say “currency risk” in P2P they usually mean one thing, but there are actually two separate exposures, and they behave differently.

The first layer is the obvious one: your money versus the loan’s money. You earn in pounds, you convert to euros, you fund a euro loan at 12%, and twelve months later you convert back. Your real return is the euro interest multiplied by whatever the exchange rate did in between. The loan can perform perfectly and you can still lose money in your own currency; the loan can struggle and a favourable rate move can bail you out. Neither outcome has anything to do with the borrower.

The second layer is structural, and almost nobody writes about it: the platform operator’s own currency position. A platform can lend in one currency while its company accounts, equity and costs live in another. That mismatch does not touch your loan contract directly, but it affects the solvency of the operator standing between you and the borrower - and as we showed in our guide to reading platform accounts, operator solvency is a risk you hold whether you think about it or not. We will come back to the clearest example in our coverage, Maclear, below.

The arithmetic: what a swing actually costs

Start with the only number that matters: your return measured in the currency you spend. The formula is simple enough to do on a napkin. Take your euro return, then multiply by the change in the exchange rate over your holding period.

Worked example, our usual EUR 10,000. Suppose you are a UK investor. At the ECB-area reference rate of roughly 0.853 pounds per euro in early October 2026 [source: ECB reference rates via xe.com, 1 Oct 2026], funding EUR 10,000 costs about GBP 8,530. The portfolio earns 12% in euros, so a year later you hold EUR 11,200.

Now three scenarios for the rate a year out:

Scenario	EUR/GBP in a year	You get back	Return in GBP
Rate unchanged	0.853	GBP 9,554	+12.0%
Euro weakens 5%	0.810	GBP 9,072	+6.4%
Euro strengthens 5%	0.896	GBP 10,035	+17.6%

The middle row is the one to stare at. A 5% adverse move - entirely ordinary for a major pair over twelve months - cut the return nearly in half. Nothing defaulted. No platform failed. The borrower paid every cent. And note the asymmetry of attention: investors routinely reject a platform over a 1% fee difference, then take an unhedged 5-10% currency position without noticing they have done so.

For a Polish investor the same logic runs through EUR/PLN, which the ECB fixed at 4.3690 zloty per euro at the end of September 2026 [source: ECB euro foreign exchange reference rates, 30 Sep 2026]. For a Swiss investor it runs through EUR/CHF - and that pair deserves its own section, because it is the one with the famous scar.

The franc below parity: why Swiss-based euro investors feel this most

The euro buys less than one Swiss franc. The reference rate sat around 0.95 francs per euro in September 2026 [source: ECB / Wise mid-market rate, Sep 2026] - a pair that traded well above parity for most of its history. The long arc has been one of franc strength, which is precisely why a Swiss-resident investor earning 14% in euros has historically kept meaningfully less than 14% in francs.

The pair is also the textbook warning against assuming currencies move slowly. On 15 January 2015 the Swiss National Bank abandoned its 1.20 floor against the euro without warning, and EUR/CHF fell by double-digit percentages within minutes. Anyone holding euro assets against franc liabilities took the whole move at once. That event is a decade old, but it is the reason no honest guide will tell you that major-pair FX risk is “a few percent a year at most”. Usually it is. Occasionally it is fifteen percent before lunch.

The flip side matters too: a euro-based investor funding euro loans on a Swiss platform carries no FX risk at all from the platform’s nationality. Where you invest from determines the exposure; where the platform is incorporated does not - with one exception, which is the operator’s own books.

Where currency costs hide on the platforms we track

Of the 19 platforms in our main coverage, the investor-facing currency is the euro essentially everywhere: Maclear, Mintos, PeerBerry, Robocash, Nectaro, Lendermarket, Crowdpear, EstateGuru and the rest all run euro accounts for European retail investors. That uniformity is good news for euro investors and uniform bad news for everyone else, because it means there is no meaningful way to build a GBP or CHF P2P portfolio on these platforms - you convert, or you stay out.

The conversion itself is where the quiet costs sit, and they arrive in up to three places:

Your bank’s spread, twice. A typical retail bank charges a margin over the mid-market rate on each conversion. Do the round trip - home currency to euros at the start, euros back home at the end - and you pay it twice. At common retail margins this alone can cost more than an entire month of interest on the position. A low-cost broker or fintech account usually cuts the round trip below half a percent; a legacy bank can multiply that several times over. This is the single most controllable number in this whole article.

The platform’s own exchange fees. Some platforms monetise conversion directly. Mintos’ 2024 accounts group currency exchange with secondary-market charges in an “other fees” line worth about EUR 1.4M of revenue [source: Mintos-full section 7, from the Mintos annual accounts] - real money, paid by investors who move non-euro funds. Our general rule from the fees guide applies here with full force: the costs that hurt are rarely on the price list’s front page.

SEPA versus international rails. Euro transfers inside SEPA are free or near-free on every platform we track. Fund the same account from a non-euro country and you may add international transfer charges on top of the FX spread. UK investors post-Brexit see this most often.

The operator-level mismatch: Maclear as the worked example

Maclear is the cleanest illustration in our coverage of the second layer of currency risk, and it cuts both ways - which is exactly why we use it.

For the investor, Maclear is a euro platform. Loans are issued in euros, interest of 14.5-14.9% realised is paid in euros, and a euro-based investor carries no FX exposure at all [source: Maclear-full section 6]. For euro investors, the Swiss address changes nothing about currency.

But the company itself is a Swiss AG that keeps its books in francs. Its FY2024 accounts - published June 2026, still unaudited - report in CHF: revenue of CHF 758,222, a net loss of CHF 122,941, negative equity of CHF 87,026, and investor funds of CHF 9.18M sitting as short-term liabilities on the AG’s own balance sheet against loans of CHF 9.30M [source: Maclear-full section 7; Maclear annual report 2024]. Those investor funds and loans are euro positions expressed in a franc ledger. When the euro weakens against the franc, the franc value of that euro loan book falls; a company whose equity is already below zero has no cushion against even routine translation effects. We flagged the thin-equity problem in our accounts guide; the currency mismatch is one more reason the audit, which the CFO says is in its final stage, matters.

To be precise about what this is and is not: it is not a risk to the denomination of your claim - your loan is in euros and repays in euros. It is a risk to the operator’s balance sheet, which is the thing that processes your repayments. We rate Maclear #3 of 44 at 8.4/10 with exactly this class of caveat priced in: outstanding realised yields and a 0.15% default record on one side, unaudited accounts, negative equity and the EUR/CHF ledger mismatch on the other.

Four honest ways to manage currency risk

Match the currency to your life, not to the yield. The cleanest hedge is structural: invest money you intend to spend in euros - a future property purchase in Spain, retirement plans in Portugal, children studying in the eurozone. Then the “risk” disappears because the euro is your real unit of account for that money.

Run your return in your home currency. Your platform dashboard will always show the euro figure. Your spreadsheet should not. As we showed in the XIRR guide, the right way to measure a portfolio is cash in, cash out, dated - so enter those cash flows in pounds or francs at the rates you actually got, and let XIRR tell you the truth. Many investors who do this for the first time discover their three-year P2P return was two points lower than they believed, none of it the platforms’ fault.

Do not try to hedge retail-size positions with derivatives. Forwards and FX futures exist, but at EUR 5,000-50,000 scale the costs, margin requirements and operational fiddle eat the benefit. Professional treasurers hedge; retail investors who try usually just add a second way to lose money. Sizing is the retail hedge: if a 10% currency move against you would change your financial plans, the position is too large.

Cut the conversion cost to the bone. You cannot control the rate; you fully control the spread. A sub-0.5% round trip through a low-cost provider versus a multi-percent round trip through a legacy bank is the difference between FX being a background noise and FX being your largest fee. Convert in few, large transactions rather than many small ones, and keep a euro balance for reinvesting so you are not paying the spread on every interest payment.

Editor’s pick for euro-denominated lending

🥇 Editor’s Pick: Maclear - #3 of the 44 platforms we cover, 8.4/10. Swiss SRO supervision, 14.5-14.9% realised yields, one default of EUR 150,000 (0.15% of funded volume) repaid in full, and fully euro-denominated loans - which means zero currency risk for euro-based investors, and a clearly understood single exposure for everyone else. We state the caveats in the same breath: SRO supervision covers anti-money-laundering only, the FY2024 accounts are unaudited with negative equity, and the operator’s franc ledger carries the EUR/CHF mismatch described above.

FAQ

Do I have currency risk if I invest in euros on a euro platform?

No, not on the investment itself. If your income, savings and spending are in euros and the platform lends in euros, the exchange rate never enters your return. The only euro-investor exception is indirect: if the platform’s operator keeps its books in another currency, as Swiss-based Maclear does in francs, the operator’s own balance sheet carries a translation exposure. That affects platform solvency risk, not the denomination of your loans.

How much does currency conversion actually cost?

It depends almost entirely on who converts for you. A low-cost fintech or broker typically prices near the mid-market rate, keeping a full round trip under 0.5%. A traditional bank margin can push the same round trip to several percent - more than a month of interest on a typical P2P position. Some platforms add their own exchange fees on top; Mintos’ accounts show currency exchange bundled into a fee line worth about EUR 1.4M in 2024.

Can the exchange rate really wipe out a P2P yield?

Over a single year, a major-pair move large enough to erase a 12-14% euro yield entirely is rare but not unheard of. A 5% adverse move, which happens routinely, cuts a 12% yield to roughly 6.4% in your home currency. The extreme case remains the Swiss franc in January 2015, when the pair moved by double digits in one morning. The realistic planning assumption is that FX adds a swing of several percent per year in either direction on top of your lending return.

Should I hedge my P2P portfolio with forwards or options?

At retail size, almost certainly not. Hedging instruments carry their own costs, margin requirements and roll mechanics that overwhelm the benefit on positions of a few thousand to a few tens of thousands of euros. The practical alternatives are structural: invest from money with a euro future, keep the position small enough that a 10% move does not change your plans, and minimise conversion costs.

Which P2P platforms let me invest in pounds or francs?

Within the 19 European platforms we cover, effectively none for retail purposes: the investor-facing currency is the euro across Maclear, Mintos, PeerBerry, Robocash, Nectaro, EstateGuru and the rest. A GBP or CHF investor converts into euros to participate. That makes the conversion route - not the platform choice - the main currency decision, and it is worth choosing a low-cost provider before choosing a platform.
