A total of €800m is being made available for lending to small and medium businesses by a new State-backed scheme.
Ministers Michael Noonan and Brendan Howlin will launch the Strategic Banking Corporation of Ireland - and will be joined by Germany's Finance Minister Wolfgang Shauble.
He says it will boost Ireland's economy and contribute to Europe.
The initiative will be administered by retail banks - and be backed jointly by Irish, German and European funding.
SCBI's lending rates are expected to come in at 1% lower than the market rate - as well as longer durations.
If there is enough demand, it is hoped that the scheme could facilitate up to €4bn in lending to the sector.
