The 12-month Euribor rate fell to 2.35 percent on Tuesday, dropping from 2.44 percent the previous day.
In a post on messaging platform X, OP Financial Group's senior market economist, Jari Hännikäinen, described the 8.6 basis point drop as a crash.
He noted that it was the largest one-day drop in the Euribor since last August and the 26th largest in its history. He suggested that trade war fears are fuelling expectations of a European Central Bank rate cut.
The Euribor is short for the Euro Interbank Offered Rate, and based on the average interest rate at which European banks borrow from one another.
This rate is commonly used as the reference rate for Finnish mortgages, making it a key influence on household finances in Finland.
