Polish Zloty: Policy Divergence Weighs on PLN Against Euro, ABN AMRO Says

ABN AMRO has warned that the Polish zloty (PLN) faces persistent pressure against the euro (EUR) due to a divergence in monetary policy between the European Central Bank (ECB) and the National Bank of Poland (NBP), as of March 2025. The bank’s analysis highlights that while the ECB has begun an easing cycle, the NBP is expected to maintain a restrictive stance, creating a policy gap that could limit zloty gains and potentially drive EUR/PLN higher.

Why Policy Divergence Matters for the Zloty

Monetary policy divergence is a key driver in currency markets. When the ECB cuts interest rates while the NBP holds steady, the interest rate differential between the eurozone and Poland narrows. This reduces the attractiveness of zloty-denominated assets for yield-seeking investors, as the relative return advantage of holding PLN diminishes. According to ABN AMRO, this dynamic is particularly relevant in the current cycle, as the ECB has signaled a more accommodative path to support a sluggish eurozone economy, while the NBP remains focused on bringing inflation back to its target.

The NBP’s cautious approach is rooted in persistent domestic price pressures, including high food and energy costs, which have kept inflation above the central bank’s 2.5% target. As of early 2025, Poland’s inflation rate stands at around 4.2% year-on-year, well above the eurozone’s 2.4% average. This divergence in inflation dynamics justifies the NBP’s reluctance to cut rates, but it also creates a policy mismatch that weighs on the zloty.

Market Implications and EUR/PLN Outlook

ABN AMRO’s analysis suggests that the zloty could remain under pressure in the near term, with EUR/PLN potentially trading in a range above the 4.30 level. The bank notes that while Poland’s strong economic fundamentals—such as robust GDP growth and a current account surplus—provide some support, the policy divergence acts as a ceiling on PLN appreciation. In contrast, if the NBP were to signal a more dovish tilt, the zloty could weaken further, as markets would price in a narrower yield advantage.

For investors and businesses with exposure to the Polish currency, this means that hedging strategies may need to account for a weaker zloty scenario. Importers, for example, could face higher costs, while exporters might benefit from a more competitive exchange rate. The outlook also has implications for the broader Central and Eastern European (CEE) region, as the zloty often serves as a bellwether for regional currencies.

What This Means for Your Portfolio

For forex traders, the key takeaway is that the zloty’s trajectory will be heavily influenced by the relative pace of ECB and NBP policy moves. If the ECB accelerates its easing while the NBP remains on hold, the zloty is likely to underperform. Conversely, any unexpected hawkish signal from the NBP could trigger a short-term rally. As always, it is crucial to monitor central bank communications and economic data releases for clues about future policy actions.

Conclusion

In summary, ABN AMRO’s assessment underscores the significant impact of monetary policy divergence on the Polish zloty. While Poland’s economic fundamentals remain solid, the current policy mix favors a weaker zloty against the euro. Investors and businesses should remain vigilant, as central bank decisions in both Frankfurt and Warsaw will be critical in shaping the currency’s direction in the coming months.

FAQs

Q1: What is monetary policy divergence?
Monetary policy divergence occurs when two central banks take different approaches to interest rates or other policy tools. In this case, the ECB is cutting rates while the NBP is holding steady, creating a divergence that affects the exchange rate.

Q2: How does policy divergence affect the zloty?
When the ECB cuts rates and the NBP does not, the interest rate differential narrows, making zloty assets less attractive to investors. This can lead to a weaker zloty against the euro.

Q3: What should investors watch for?
Investors should monitor NBP and ECB policy announcements, as well as inflation data from both regions. Any shift in policy stance could trigger significant moves in EUR/PLN.
