A strong forint puts the euro back on the agenda: when and on what conditions could Hungary adopt it?

A strong forint, a long-running question

The forint strengthened markedly in the first half of 2026, reaching around 348 against the euro in mid-June, close to a four-year high. Several analyst houses had earlier projected a rate closer to 390 for the end of 2026, so the current level is striking even against that.

Several factors lie behind the strengthening at once. One is the tight monetary policy of the National Bank of Hungary (Magyar Nemzeti Bank, MNB) and the relatively high interest rate level, which through the gap between domestic and foreign rates makes forint-denominated assets attractive. The international environment was also supportive, with growing rate-cut expectations in developed markets. The picture was further improved by market confidence tied to greater economic-policy predictability and by optimism about the inflow of EU funds.

It is important to see that a strong forint cuts both ways. On the one hand it moderates import prices and helps bring inflation down, which benefits households and price stability alike. On the other hand it can be less favourable for exporters and for businesses earning mainly in foreign currency, because the same foreign-currency revenue is worth fewer forints. The exchange rate is therefore not good or bad in itself, its effect always depends on the position of the economic actor.

What does joining the euro area mean?

Joining the euro area means joining the world's second most important reserve currency and one of its most traded currencies. Currently 21 EU member states use the common currency, the most recent to join being Bulgaria, which adopted the euro on 1 January 2026.

As a general rule, every EU member state has undertaken to adopt the euro once it meets the conditions. The only exception is Denmark, which is exempted by an opt-out clause set out in the EU treaties. Hungary has no such exemption, so euro adoption is not a question of intent in principle but of meeting the conditions and of timing.

The Maastricht criteria

Adopting the euro requires meeting the conditions laid down in the 1992 Maastricht Treaty, commonly known as the Maastricht criteria. These are economic and legal requirements meant to ensure that a country joins well prepared and operates smoothly within the euro area. The economic conditions rest on four pillars, complemented by legal convergence.

The exchange-rate condition deserves particular attention. The country must participate for at least two years in the exchange rate mechanism (Exchange Rate Mechanism, ERM II), within which the national currency may move by at most 15 percent in either direction from the central rate fixed to the euro, and no devaluation may take place during this period. The aim is to demonstrate that the economy operates stably even without excessive exchange-rate swings. Since 2018, member states wishing to join ERM II must also cooperate more closely with the single supervisory mechanism of the European Central Bank (ECB).

Where does Hungary stand now?

The current strong forint is a favourable backdrop for the exchange-rate stability condition, and the path toward lower inflation also helps the price-stability criterion. These, however, are only parts of the picture. The decisive factor is that Hungary is currently not a member of the exchange rate mechanism, and a successful period of at least two years in ERM II is an indispensable precondition for adopting the euro. For this reason, even under the most favourable scenario we are talking about several years until entry.

The government-debt ratio has persistently been above the 60 percent reference value, and bringing the budget deficit sustainably below three percent requires continuous discipline. Bringing inflation down and keeping it durably low is also a key question. All of this means that the criteria are not met at once, in a single good year, but require sustained performance over several years.

The process: who decides and how?

Euro adoption is not decided by a single actor. The ECB and the European Commission examine at least every two years, and at the request of the member state concerned, whether countries outside the euro area meet the conditions, and they set out their findings in a convergence report. The Council of the EU then decides whether the given country may adopt the euro, after the Commission has submitted its proposal, the euro-area member states have sent their recommendation, and the European Parliament has been consulted.

The closing step of the process is the final, irrevocable fixing of the conversion rate. This is set by the Council of the EU on the basis of a Commission proposal and after consulting the ECB, by a unanimous decision of the euro-area member states and the entering country. Adopting the common currency is thus a strictly regulated, multi-stage procedure in which the EU institutions and the member states take part jointly.

What does entry mean in everyday life?

Euro adoption brings several lasting obligations. The conversion rate between the national currency and the euro is fixed permanently, the conduct of monetary policy passes to the ECB, and the country takes part in the euro area's coordinated crisis management and in closer fiscal coordination. During the practical changeover the old currency is exchanged for euros at the fixed rate, typically with a transitional dual-display period that helps the public adjust.

There are arguments both for and against entry. The common currency eliminates exchange-rate risk in trade with the euro area and can reduce transaction costs and borrowing costs, but it also entails the loss of an independent monetary policy and of the country's own exchange rate as a tool of adjustment. The timing of accession and the creation of its conditions are therefore at least as much a matter of economic policy as of technical judgement.

What does the 2030 horizon mean?

There is currently no official, fixed target date, yet a horizon around 2030 keeps recurring in public discussion as a possible frame. Whether this is realistic depends primarily on when and on what terms the country joins the exchange rate mechanism, and how sustained its compliance with the criteria is.

The forint, which has strengthened significantly since April 2026, has understandably revived the debate about the euro, but adopting the common currency is not a question of the exchange rate. It is a multi-year, criteria-bound process. Meeting the Maastricht criteria, at least two years in the exchange rate mechanism and legal convergence are all necessary conditions, and the final decision is taken jointly by the EU institutions and the member states. The current strong exchange rate can ease this path but does not replace it.
