The potential for businesses to dramatically cut costs by merging their IT departments will act as a major catalyst for consolidation in the financial services industry.
Overall spending by Europe's banks and financial services industry on IT will fall by about 8% (£12.6bn) within five years, as merged businesses rationalise their IT departments, research by Datamonitor predicts.
The findings illustrate a growing trend for businesses in all sectors of the economy to achieve efficiency savings by merging IT operations.
But mergers are not a quick fix for struggling companies, Datamonitor reveals. Companies will have to increase their IT spending by an average of 15% in the first few years after a merger as they struggle to merge their systems.
It will take five years before the IT budget falls to 70% or 80% of the combined budget of the merged companies.
Companies can achieve quick savings in spending on front-office systems, but merging back-office systems can often prove problematic. In some cases this can significantly reduce the cost benefits of a merger.
Daniel Mayo, banking and finance analyst at Datamonitor, said, "It is important not to underestimate the problems. When it comes down to merging IT, it is often a case of trying to hammer round pegs into square holes."
Lloyds TSB, for example, has been unable to combine the Lloyds and TSB back-office systems. Customers of each bank are unable to access the same banking services and the cost savings have not been as high as they could be.
The Bank of Scotland has predicted it can save £290m in its takeover battle with NatWest.
