The Labour Party has called on the Government to conduct detailed research into the possible consequences of the maturing of Special Savings Incentive Accounts (SSIAs) in the coming years.
The party said more than €8bn could flow into the economy when the accounts mature in 2006 and 2007.
Economic commentators have predicted that most of the money will be reinvested, but many people will also spend their funds on cars, home improvements, holidays and other items.
Labour TD Joan Burton said she was concerned that this could push up inflation and damage the economy in general.
