Of the many challenges confronting banking today, three are of  surpassing importance. They are: (1) raising the unsatisfactory revenue   growth in many business lines; (2) capitalizing on the scale economies   available in many specialty businesses; and (3) reinvigorating the lagging   retail franchise.       
For many banks, meeting these three challenges necessitates formal  mergers with other banks or nonbanks. Clearly, however, formal merger is   not the only way to cut costs, raise revenues, and acquire the wherewithal   to make investments in new products.     
  
Much can be accomplished along these lines through a variety of  activities that fall short of actual merger but can nonetheless achieve   many of its objectives. These activities can be grouped under the heading   of alliances - associations among banks or between banks and nonbanks to do   together what was formerly done separately.       
One can envision revenue-enhancing and cost-cutting alliances  penetrating several areas of banking life. 
  
For the moment, however, alliance activity is centered on bank  transaction processing businesses - those technology- and operations-   intensive activities that soak up about 20% of overall bank noninterest   expense but would preempt much less if there were a higher degree of   interbank cooperation. (In Norway, for example, the entire banking industry   uses a common back office.)         
Businesses susceptible to alliance activity include check and card  processing, data center management, mortgage servicing, securities   servicing, and trust recordkeeping.   
In the past two years, First Manhattan Consulting Group has assisted in  the birth of a number of alliances in these businesses, including that of   Bankers Trust and First Fidelity in check processing, Wells Fargo and CES   in merchant processing, and Chemical and Mellon in the securities area. As   this is written, other deals are in the works.       
  
Spurred by these associations, a growing number of institutions feel  that now is the opportune time to conclude agreements that will cut costs   and have the potential to raise revenues in processing activity in the   short run and preserve control over threatened businesses, including   perhaps the entire payments mechanism, in the long run. Alliances are   necessary and timely not only because of redundant facilities, but also   because of the need to:           
1. Replace aging core systems.
2. Introduce new products and services.
3. Bring on stream whole new technologies (e.g., image POD).
  
At the most elemental level, an alliance is a device with which to flout  the seemingly iron laws of arithmetic - to turn one plus one into at least   2#1/2. Stated differently, when, for example, one extracts the check-   processing business from two good-sized regionals and rehouses it in a   stand-alone entity, one generates more shareholder value than was embodied   in the sum of the two preexisting businesses.         
Part of the increment to value stems from the elimination of redundant  facilities - e.g., processing centers. Another part reflects the impact of   larger scale on variable costs. Two banks, each with 10 million prime pass   items per month, will process at a unit cost of about 4 cents. A combined   20-million-prime-pass-per-month entity will process at a unit cost of only   about 3 cents.         
Having lower unit costs, the new entity can reprice its services,  thereby stimulating sales to smaller banks and improving cash management   effectiveness.   
Additionally, not being a bank, the stand-alone check-processing vehicle  generally can attract business from other banks that would not have been   available to the two sponsoring institutions for competitive reasons. In   this case, then, an alliance can increase revenue as well as lower costs.     
A final advantage of an alliance is a spillover from the scale effect -  namely, with increased volume, it becomes possible for a given entity to   introduce technologies that would not be economically justified at a lower   level of activity.     
An example once again comes from check processing. At volumes below 100  million prime pass items per year, conventional technology yields lower   unit costs than image POD. At higher volumes, image gets the nod. Indeed,   when volumes exceed 200 million, the unit cost of imaging amounts to about   a third lower than that of the conventional technology.       
The bigness imperative in check processing is reinforced by the  strategic aims of technology vendors like IBM, EDS, Systematics, Fiserv,   and Unisys. These are trying to build scale processing facilities in high-   volume geographies that will be linked through proprietary communications   networks.       
The eventual objective is to create a standardized infrastructure with  which to do nationwide image net settlement. If sufficient volume can be   attracted, the ability to "net settle" across regions will considerably   reduce, if not eliminate, the transportation costs and float impacts   associated with the physical movement of checks.       
Although the technology vendors can try to constrict the role of the  banks in the payment system, this is an expensive and time-consuming   strategy, given that the banks currently control the bulk of the payments   volume. These vendors are instead trying to joint venture with banks,   region by region, in order to acquire the volume needed to activate their   nationwide image platforms.         
The need to partner is also apparent in other processing activities. Big  mortgage companies can service loans at an appreciably lower cost than   smaller ones, enabling them to bid more for servicing rights than the   smaller entities.     
Big trust record-keepers are far more economic than small ones, enabling  them to underbid the latter for 401(k) plans. In other words, in these   businesses, bigness has already begotten, and will increasingly beget, more   bigness.     
To gain the advantages of scale, a typical regional bank must choose  among essentially three options: 
1. Get out of processing businesses by outsourcing to larger banks,  alliances of banks, or technology vendors and their allies. 
2. Stay in these businesses by merging or forming alliances with banks.
3. Stay in these businesses by allying with a technology vendor.
As a general rule, admitting of exceptions, the optimal choice depends  on current and projected volumes. At low volumes - e.g., in mortgages,   fewer than 80,000 loans serviced - outsourcing the business to an efficient   processor makes sense.     
At intermediate volumes - e.g., between 80,000 and 200,000 mortgage  loans serviced - searching for alliance partners with whom one can   associate on more or less equal terms becomes feasible. Finally, at higher   volumes, the institution can itself contemplate becoming a servicer for   other institutions' mortgage loan volumes.       
Assuming that a given bank resides in the intermediate-volume zone, with  whom does it ally, a technology vendor or another bank? As already noted,   there can be advantages to hooking up with a technology vendor in check   processing.     
A bank-to-bank alliance, however, can produce more immediate benefits.  Since another bank will add check-processing volume, while a technology   vendor currently has little or no volume to contribute, an all-bank tie-up   will yield greater initial unit cost savings.     
These gains must be weighed against the possibility that an alliance  with a technology vendor will spare a regionally dominant bank the need to   invest in image POD and will facilitate eventual entry into the projected   national image exchange network - circumstances that could convey both   greater float and unit-cost advantages than were possible through a bank   alliance.         
Conceivably the optimal strategy in check processing may be a two-staged  one. First, do an all-bank alliance. This adds to volume and raises the   bargaining leverage of the bank-formed entity, which is then better able to   negotiate a second deal with the technology vendor.     
At the moment, there are no alliances between banks and technology  vendors in check processing, although there is a significant amount of   outsourcing. But there are a number of deals under consideration.   
Should one eventuate, others - and perhaps a flurry - will follow. Many  banks that have been slow to consider alliances with technology vendors   could then find themselves quickly outflanked and thus competitively   disadvantaged.     
In many businesses, the choice of a partner will depend on the trade off  between the revenue and cost-savings potential of a given deal and its   ownership options. If a bank finds it necessary to throw in its lot with a   larger bank in its region, its equity stake in the venture will generally   be less than half. By contrast, it may be easier to negotiate a more   favorable split with a technology vendor.         
And a big piece of a smaller operation with a strong growth potential  can be worth more than a small piece of a bigger operation with a more   limited growth outlook.   
In determining whether to seek alliances, a bank must answer four big  questions. The first is: Is sole ownership of a particular activity   critical to its success?   
An affirmative answer self-evidently ends the inquiry. A negative answer  elicits the second question, which is: Does the bank have a technology   advantage in the business that is sustainable?   
Again, affirmative answer, no point in continuing; negative answer, push  on to the third question, which is: Is the bank operating in this business   at a maximum scale advantage? If the bank answers "no" to this query, it   then must pose the final question: Do we have something to contribute to a   prospective alliance? This time it is a negative answer that shuts off   further discussion, while an affirmative one suggests the strong need to   explore alliance possibilities.           
Finally, it is important to emphasize that alliances are risky ventures  which may not live up to their advertised potential. Hence, it is vital to   pay attention to the following five prerequisites for success:   
1. Make sure that all potential partners have been considered.
2. Make sure that the economics of the deal take into account the value  added by each party. 
3. Ensure compatibility of participant strategies and culture.
4. Guarantee that all scenarios result in gains for each party.
5. Ensure that there is an agreed-on approach on how to deal with new  services or changes in services that are likely to occur. 
If a bank does the appropriate soul-searching and then structures any  prospective deal with an eye to satisfying the above prerequisites, it   stands more than a fair chance of emerging as a winner in this brave new   world of processing alliances.
