Deputy government chief whip Billy Kelleher has called for the exploration of legal avenues to force all of the financial institutions to pass on mortgage interest cuts to homeowners.
A cut of a half of one percent was announced this week by the European Central Bank. A number of banks have passed on the saving to mortgage-holders, but a number have not yet done so.
Dep Kelleher said it was a "breathtaking arrogance" that, in some cases, the cuts have not been passed on yet.
