Currency Depreciation: How EUR, PLN, CZK, HUF Moves Hit EU/CEE Investors (and Hedge Strategies)

TL;DR

Currency movements are one of the most underappreciated drivers of investment returns and household purchasing power. In May 2026, EUR/USD trades around 1.09, EUR/PLN around 4.28, EUR/CZK around 24.6, and EUR/HUF around 392. A 10 percent EUR depreciation against the USD imports roughly 0.5 to 1.0 percentage points of additional eurozone inflation over 12 months and immediately boosts the EUR value of USD-denominated assets by the same amount. CEE currencies have moved in wider ranges: PLN was at 3.85 against EUR in early 2024 and has weakened roughly 11 percent since; HUF is roughly 4 percent weaker year-over-year. This article explains why currencies move, how depreciation affects your assets and bills, and the main hedge strategies available to EU and CEE retail investors.

Definition: What Currency Depreciation Actually Means

A currency depreciates when its market price (in terms of another currency) falls. EUR/PLN rising from 4.20 to 4.35 means PLN depreciated against EUR (it takes more PLN to buy one EUR), and equivalently EUR appreciated against PLN.

Three related but distinct concepts:

• Nominal depreciation — the headline FX rate change.
• Real depreciation — the FX change adjusted for inflation differential. If PLN depreciates 5 percent nominally but Polish inflation is 3 percentage points higher than eurozone inflation, real depreciation is only ~2 percent.
• Effective exchange rate (NEER/REER) — depreciation against a trade-weighted basket of currencies, not just a single pair. Published by ECB and NBP.

Contrast with:

• Devaluation — a sudden, policy-driven depreciation in a pegged or managed currency. Different from market-driven depreciation. The eurozone, Poland, Czechia and Hungary all have floating currencies, so they technically can't "devalue" in the historical sense.
• Currency crisis — a sudden, disorderly depreciation, typically more than 20 percent in weeks, often with capital flight. Hungary 1996, Turkey 2018, Russia 2014.

How Currency Moves Are Measured

Spot exchange rates are continuous market prices, quoted 24/5 by global FX dealers (volume around 7.5 trillion USD per day). The most-watched benchmarks:

• ECB reference rates — daily fix at 14:15 CET, published as the official EUR cross-rates against 31 currencies. Free, transparent.
• NBP fixing — published daily by Polish National Bank at 11:00 and 14:00 CET for PLN cross-rates.
• Effective exchange rates — calculated monthly by ECB and BIS using trade weights.

Frequency: continuous spot, daily official fixes, monthly effective rate publications.

What to look at:

• 1-year and 5-year nominal range to gauge current stress.
• REER (real effective exchange rate) — if it's 10 percent above its 10-year average, the currency is "expensive" historically; if 10 percent below, "cheap."
• Forward curve (FX forwards) — embeds interest rate differential and expected depreciation.
• Implied volatility — option market's expected magnitude of future moves.

What to ignore: intraday wiggles, single-day moves of less than 0.5 percent, FX strategist forecasts more than 6 months out (forecast accuracy historically poor).

A Short History of EU/CEE Currency Moves

EUR/USD since 1999 has ranged from 0.82 (October 2000) to 1.60 (July 2008). Long swings, often 5 to 8 years per direction. Currently mid-range at ~1.09.

EUR/GBP experienced shock in 2008 (post-crisis sterling collapse from 0.70 to 0.95) and 2016 Brexit (from 0.78 to 0.92). Currently around 0.86.

EUR/PLN has had three major episodes:

• 2008 to 2009 GFC: from 3.20 to 4.90 in 9 months (PLN crash).
• 2011 to 2015: gradual recovery to 4.20 to 4.40 range.
• 2020 to 2022: COVID + Ukraine war pushed it from 4.20 to 4.85 peak.
• 2022 to 2024: strong PLN recovery to 3.85 with NBP rate advantage.
• 2024 to 2026: modest PLN weakening back to ~4.28 as ECB-NBP spread narrows.

EUR/CZK has been the most stable CEE pair (the Czech National Bank's "managed float" with implicit cap above 27 broke in 2017). Range mostly 24 to 27 over 2018 to 2026.

EUR/HUF has shown the largest sustained depreciation: from 250 in 2008 to ~410 peak in late 2022. Currently around 392. Hungarian forint has been the weakest CEE major currency, reflecting fiscal stress, central bank credibility issues and EU funding disputes.

Historical pattern: CEE currencies typically weaken sharply during global risk-off episodes (2008, 2020, 2022) and gradually recover during risk-on periods. Beta to global risk appetite is roughly 1.5x EUR.

What Drives Currency Moves

Currencies are driven by combinations of:

1. Interest rate differentials — higher local rates attract capital, supporting the currency. EUR-USD historically correlates ~0.6 with the German-US 2-year yield spread.

2. Inflation differentials — higher domestic inflation eventually weakens the currency via purchasing power parity (long-term, decades).

3. Current account balance — persistent trade deficits weaken the currency; surpluses strengthen. Eurozone runs a current account surplus of ~2.5 percent of GDP, supportive of EUR. Hungary runs a deficit, pressure on HUF.

4. Risk sentiment — safe-haven flows lift USD, JPY, CHF; weaken EM and CEE currencies.

5. Central bank credibility — if markets trust the central bank to defend inflation target, the currency holds value. Hungarian MNB has had credibility issues; Czech CNB and Polish NBP much higher credibility.

6. Political risk — elections, fiscal crises, EU disputes can shock currencies short-term.

7. Commodity terms of trade — commodity exporters (NOK, AUD, CAD) move with oil and metals; importers do the reverse.

For EUR specifically in 2026: ECB easing cycle relative to Fed is a key driver. If ECB cuts faster than Fed, EUR weakens; if Fed cuts faster, EUR strengthens.

Direct Impact on Your Personal Finance

1. Imported inflation

A 10 percent EUR depreciation against USD raises EUR-priced energy, raw materials and imported goods. Pass-through to consumer prices is typically 10 to 20 percent of the FX move within 12 months — so 10 percent EUR/USD depreciation adds 1 to 2 percentage points to HICP over a year.

For PLN: a 10 percent PLN depreciation against EUR adds roughly 1.5 to 2.5 percentage points to Polish CPI over 12 months. Polish economy is more import-intensive than the eurozone, so pass-through is higher.

2. Foreign asset returns

If you hold a USD asset and EUR depreciates 10 percent against USD, your asset gains 10 percent in EUR terms even if the asset is flat in USD. This is the FX kicker.

Example: 50,000 EUR in a USD-denominated S&P 500 ETF. S&P returns 0 percent over a year. EUR/USD goes from 1.10 to 0.99 (10 percent EUR depreciation). Your EUR position is now worth ~55,556 EUR. Pure FX gain of ~5,556 EUR.

This is symmetric — EUR strengthening hurts foreign holdings.

3. Mortgage in foreign currency

The notorious example: Polish CHF mortgages from 2005 to 2008. When CHF/PLN went from 2.20 to 4.20+, monthly payments doubled in PLN terms. A 200,000 CHF mortgage became 840,000 PLN at peak vs the original ~440,000 PLN equivalent.

In 2026, fewer households hold FX mortgages but the lesson remains: never borrow in a currency you don't earn in unless you fully understand and accept the FX risk.

4. International travel and online shopping

EUR depreciation against USD makes US holidays, Apple devices and many subscription services (Netflix EU, Spotify EU) more expensive. Pass-through here is fast: subscription services typically reset prices within 6 to 12 months of large FX moves.

5. Wages and savings

If you earn in PLN and save in PLN, day-to-day life is unchanged when PLN depreciates against EUR — except your future eurozone travel/retirement/imports get more expensive.

If you earn in EUR but live in a CEE country (or vice versa), FX moves directly hit your real wage.

Country-by-Country Variation: CEE FX Snapshot (Spring 2026)

CEE currencies show higher implied volatility than developed-market pairs. HUF has the highest, RON the lowest (managed). PLN volatility has fallen from 9 percent in 2022 to 6 percent now as NBP credibility has strengthened.

What Investors Historically DO with FX Information

Educational framing — depending on time horizon and base currency, historical patterns observed when FX moves dramatically include:

• For EUR-based investors holding USD assets: many run a partial currency hedge — typically 30 to 70 percent of USD exposure, leaving some unhedged for the FX kicker.
• For CEE investors holding EUR assets: similar partial hedge logic. Many CEE investors deliberately hold some EUR exposure as a hedge against domestic currency depreciation, treating it as portfolio insurance.
• When local currency is materially undervalued on REER basis (PLN below 3.90 in 2024 was historically cheap, PLN above 4.50 historically expensive): some investors tilt currency exposure accordingly.
• In FX-crisis countries: many investors historically increased hard-currency (EUR, USD, gold) allocation as a wealth-preservation measure rather than a return-seeking trade.

Hedge instruments accessible to retail:

• Currency-hedged ETFs — e.g., MSCI World EUR-hedged variants. The hedging cost is roughly the interest rate differential (currently EUR-USD ~1.5 percent per year cost to hedge USD assets back to EUR).
• FX forwards — available via some brokers; common for amounts above 25,000 EUR.
• Multi-currency cash buckets — held at neobanks (Revolut, Wise, N26) for natural hedge if you have multi-currency expenses.
• Foreign currency bonds — e.g., Polish investor holding USD treasury bonds gets both yield and FX exposure.

Many investors avoid trying to actively trade currencies (FX is one of the hardest asset classes to forecast) and instead manage exposure — deciding what fraction of net worth they want denominated in each currency.

Common Misunderstandings

Myth 1: "Currency depreciation is always bad." Not for net exporters or for households holding foreign assets. A weaker EUR benefits German exporters; a weaker PLN benefits Polish IT services exporters and tourism. The pain is concentrated in importers and FX-borrowers.

Myth 2: "PPP (purchasing power parity) means currencies must mean-revert." Long-term tendency yes (correlation across decades), but persistent gaps can last 5 to 10 years. PPP is not a tradeable timing signal.

Myth 3: "Hedging always reduces risk." Hedging reduces FX risk but introduces basis risk and costs. For a long-horizon investor with diversified global equity exposure, the FX volatility is often partly diversifying — completely hedging may not reduce total portfolio risk.

Myth 4: "Polish CHF mortgage holders were just unlucky." They took a known FX risk; the magnitude was historic but the direction was always possible. The lesson is structural: never borrow in a non-income currency without explicit hedging.

Worked Example: A Polish Investor's Multi-Currency Portfolio

Anna in Warsaw, age 38, has 400,000 PLN net worth split:

• 100,000 PLN cash and PLN deposits
• 100,000 PLN in Polish equity ETF (WIG20)
• 100,000 PLN in EUR-denominated MSCI World ETF (currently ~23,400 EUR at EUR/PLN 4.28)
• 100,000 PLN in USD-denominated S&P 500 ETF (currently ~26,500 USD at USD/PLN 3.78)

Scenario A: PLN weakens 10 percent against both EUR and USD over a year. Underlying equities flat.

• PLN cash: unchanged at 100,000 PLN.
• WIG20: unchanged at 100,000 PLN.
• EUR ETF: 23,400 EUR × new EUR/PLN of 4.71 = ~110,000 PLN. (+10k)
• USD ETF: 26,500 USD × new USD/PLN of 4.16 = ~110,200 PLN. (+10.2k)
• Total: ~420,200 PLN.

The foreign currency allocation cushioned against PLN depreciation.

Scenario B: PLN strengthens 10 percent against both. Underlying equities flat.

• Same logic in reverse. Total: ~380,000 PLN.

If Anna had been 100 percent PLN-denominated, she would be insulated from FX but exposed to Polish-specific shocks. Her 50/50 PLN/foreign split halves FX risk both ways while providing partial protection if PLN drops.

Cost: holding the EUR and USD ETFs in PLN brokerage account means each currency conversion has a 0.2 to 0.5 percent spread, eating into returns over many transactions.

Polish Reader Angle

PLN depreciation directly raises Polish inflation (pass-through ~20 percent of the FX move within 12 months) and the cost of imported consumer goods, fuel, and Western European vacations.

It also raises the PLN-equivalent value of:

• IKE/IKZE holdings in EUR or USD ETFs.
• USD-denominated retirement assets held abroad by Polish emigrants.
• Foreign-currency deposits at Polish banks (where allowed).

NBP's reaction function: when PLN weakens disorderly, NBP either intervenes via FX sales (relatively rare since 2022) or signals tighter monetary policy (more frequent). EUR/PLN spikes above 4.40 to 4.50 historically trigger more hawkish NBP communications.

For Polish IKE/IKZE portfolios, partial international diversification provides currency hedging against domestic PLN risk. A common approach is 50 to 70 percent global equity (mostly EUR/USD-denominated) and 30 to 50 percent Polish assets (WIG20 ETF, Polish bonds, Polish retail treasury bonds).

CHF mortgage holders who haven't yet settled with banks: the EUR/CHF and PLN/CHF rates remain volatile. CHF currently ~4.32 PLN — well above the 2-3 range when most CHF mortgages were originated.

FAQ

Q: Should I hedge my foreign-currency ETF holdings? A: Educational framing — depends on time horizon (long-horizon investors often hedge less), base currency volatility, and total portfolio diversification. A 30 to 50 percent hedge ratio is common in academic literature for diversified equity portfolios.

Q: What's the cost of hedging EUR/USD? A: Roughly the interest rate differential — currently ~1.5 percent per year cost to hedge USD-denominated assets back to EUR. Cost reverses if EUR rates rise above USD rates.

Q: Is gold an FX hedge? A: Gold is priced in USD globally. For EUR investors, gold provides partial inflation hedge but adds USD exposure. EUR-hedged gold ETFs strip out the FX component.

Q: Why is HUF weaker than PLN despite similar economic size? A: Multiple factors: Hungarian MNB credibility issues, EU funding disputes, more open economy with structural deficits, and political risk premium. Forint has consistently traded weaker than PLN on REER basis since 2010.

Q: Can the EUR really collapse? A: Eurozone disintegration risk is very low absent a major political shock. EUR has range-traded against USD for 25 years between 0.82 and 1.60 — that's volatility, not collapse. The deeper risk is fragmentation (BTP-Bund spreads widening) rather than EUR ceasing to exist.

Q: Where do I find FX rates I can trust? A: ECB reference rates (free, official, daily). NBP fixing for PLN cross-rates. For trading rates, your broker or bank — but mind the bid-ask spread, which is typically 0.3 to 1.0 percent for retail.
