ECB rate decision and Irish mortgage transmission
The ECB's Governing Council is deciding whether to cut its deposit rate from 4.00% to 3.75%. Euro-area HICP inflation is 2.9%, core inflation 3.1%, unemployment 6.5% and GDP growth 0.3%. In Ireland, the average variable mortgage rate is 5.1%, a tracker rate is 4.2% and a new fixed rate is 4.0%. Irish CPI inflation is 3.6%, driven by services and rents, while goods prices are falling. An Irish bank reports net interest income up 18% and loan growth of 0.8%. The government is running a budget surplus, and the finance minister argues that a rate cut would 'unfairly boost house prices'. The ECB must decide whether to cut, hold or signal a future cut, and how to communicate the decision. Its mandate is price stability for the euro area.
1. Explain how a change in the ECB deposit rate is transmitted to Irish mortgage holders and firms. Why might transmission be weaker in Ireland than in the euro area average?

The deposit rate influences short-term money-market rates and bank funding costs. When the ECB cuts, banks may lower tracker and variable mortgage rates, and new fixed rates may fall. Lower mortgage repayments raise households' disposable income; lower business loan rates may raise investment. Asset prices and confidence can also respond.
Transmission is weaker in Ireland for several reasons. A large share of mortgages is now on fixed rates, so existing borrowers do not feel a rate change until their fix ends. Trackers adjust quickly, but many have been sold or redeemed. Irish banks may not pass on the full cut because they need to rebuild margins, face higher capital requirements or have limited competition. Loan growth is only 0.8%, suggesting weak credit demand even if rates fall. The Irish CPI basket is dominated by services and rents, which are less sensitive to interest rates than goods. The finance minister's concern about house prices reflects inelastic housing supply: lower rates may raise demand more than supply, especially in a shortage.
2. Using the data, argue for and against a 25 basis point cut. Which mandate considerations should dominate?

For a cut: euro-area inflation at 2.9% is close to the 2% target, core inflation is 3.1% and falling, GDP growth is only 0.3%, and unemployment at 6.5% suggests spare capacity. A small cut would reduce the risk of overtightening and support investment. A signal of future cuts could lower market rates without a large immediate move.
Against a cut: core inflation at 3.1% is still above target, services inflation is sticky, and Irish CPI at 3.6% shows persistent price pressure in some regions. Bank net interest income is up 18%, which may mean rate cuts are not fully passed on anyway. House prices and rents are already under pressure, and a cut could add demand in a supply-constrained market. The government's budget surplus means fiscal policy is also stimulating, so monetary easing may be pro-cyclical.
The ECB's mandate is euro-area price stability, not Irish house prices or Irish CPI. It should give most weight to euro-area HICP and core inflation, and to the risk of undershooting the target. A 25bp cut can be justified as insurance if inflation is on a sustained downward path, but the communication should stress data dependence rather than promise a series of cuts.
3. Evaluate the finance minister's claim that a rate cut would 'unfairly boost house prices'. What other policies could address housing affordability?
Read the worked answer
The claim has some logic. Lower mortgage rates raise the amount buyers can borrow and may increase housing demand. If supply is inelastic, much of the demand increase is capitalised into higher prices. In that sense, a rate cut can redistribute gains toward existing owners and lenders rather than new buyers.
But the claim is incomplete. Irish house prices are driven mainly by supply shortages, planning constraints, construction costs and demographic demand. A 25bp cut is small relative to these forces. Monetary policy is also a blunt tool: it cannot target one sector, and the ECB must set rates for the euro area, not for Irish housing. Using higher rates to suppress house prices would unnecessarily slow the whole economy.
Better policies include increasing public housing and serviced land, reforming planning, taxing vacant sites, and using macroprudential rules such as loan-to-income limits to prevent excessive credit. A targeted rent subsidy could help affordability but may raise rents if supply is fixed. The minister should not ask the ECB to solve a structural housing problem with monetary policy; fiscal and regulatory tools are more appropriate.
