Euribor flatlines at 2.80% in June amid Middle East peace hopes, yet mortgage bills keep climbing

Why Euribor matters

The Euribor is the rate at which top European banks lend to one another and serves as the base for millions of variable-rate mortgages in Spain. After bottoming out at 2.081% in June 2025, it began climbing as the war in Iran drove up energy costs and pushed eurozone inflation above the ECB’s 2% target. On 11 June 2026 the European Central Bank reacted with its first rate increase in nearly three years, lifting the deposit facility to 2.25%. Markets had largely priced in that move, and the index’s rise had already accelerated from 2.221% in February 2026 to 2.804% in May.

June marks a plateau at two-decade highs

The June average landed at 2.801%, effectively flat against May. Daily quotes touched 2.755% before settling back, a sign that the upward momentum has broken. Experts say the index discounted not only the June hike but also a possible second increase, which now looks less likely.

Expectations of further rate rises have diminished because the Middle East outlook has improved. The Euribor is anticipating that there will be no more hikes, since there will be less need to control inflation.

The year-on-year swing from June 2025’s 2.081% is 0.72 points, the sharpest such move since the post-pandemic tightening cycle.

Mortgage payments rise despite the stall

Because most loans reset against the year-ago level, the flat monthly reading still translates into higher bills. For a €300,000 mortgage over 25 years with a 1-point spread, an annual revision adds about €130 a month (€1,550 a year). A semi-annual revision adds roughly €94 a month (€564 per half-year). A more typical €170,000 loan over 30 years with a 0.99% spread sees a jump from €735.92 to €805.12, about €70 extra each month. Even a smaller €150,000 loan over 25 years rises by €13 a month, or €155 a year. New borrowers face stiffer offers because banks, facing less competition, have not trimmed margins.

The Euribor could oscillate around current levels in the coming months. A lasting de-escalation of the conflict and a clear moderation of inflation would open the door to declines, while another energy spike or signs of second-round effects could push it up again.

Geopolitics and the ECB’s next meeting

The stabilisation is partly tied to progress in US-Iran peace negotiations. If the Strait of Hormuz reopens, energy costs could ease further. Spanish inflation, however, closed June at 3.2% for a third straight month, still roughly a point above where it began the year. The ECB’s next policy meeting on 23 July will be the next catalyst; another hike could push the Euribor higher by September. For now, analysts see the index trading in a 2.6%–2.9% range. Homeowners with anniversary reviews will continue to absorb the lagged impact of the rate surge for several more months.
