SBAB and Länsförsäkringar are thus following last week's announcement from Handelsbanken and Skandia, who also lowered their variable mortgage rates.
"The rate cut is primarily a result of decreasing funding costs", writes SBAB in a press release.
Both SBAB's and Länsförsäkringar's rates on mortgages with longer binding periods, 1-10 years, remain unchanged.
The Swedish Central Bank is expected to lower the repo rate by 0.25 percentage points to 2.50 percent on Thursday - which would mean that the repo rate has been lowered by a total of 1.50 percentage points this year.
Next year, further rate cuts are expected.
The Swedish Central Bank has flagged in its interest rate path a repo rate of 2.25 percent by the summer of 2025, i.e. a cut after the expected December cut.
Most analysts, however, expect two cuts in 2025, while market players in their pricing expect three cuts of 0.25 percentage points.
