Credit Suisse is reducing its reliance on branches in its home market and instead pumping several hundred million francs into digital services.
The investment is said to be in the "high three-digit million range".
The bank is creating a new business area, dubbed Direct Banking, for retail and commercial clients, while its Swiss investment banking operations will become a separately managed unit.
The achievement of long-term success will not depend on having the biggest branch network in the future"
"The achievement of long-term success will not depend on having the biggest branch network in the future," Thomas Gottstein, head of Credit Suisse's Swiss Universal Bank (SUB) unit, said without elaborating on any branch closures.
"Instead, having the best digital offering - combined with access to advice from any location and the best service quality - will be the deciding factor," he said in a statement.
The new business will tend to nearly one million retail and 60,000 commercial clients using core banking offerings.
According to the bank, it will combine digital solutions with personal advice. It places an emphasis on personal contact, such as through an increase in telephone advisory services.
The new division will employ 500 and be headed by Mario Crameri, who previously worked as head of IT and operations at SUB.
Beyond digital services, Credit Suisse said it planned increased telephone advisory services and "the provision of personal advice in the regional network of branches".
More details about the new branch concept would be provided in the first half of 2020, the bank said.
At the same time, Credit Suisse will manage its Swiss investment banking division as a separate business area. At present, the unit is part of Corporate & Investment Banking.
The business will remain under the leadership of Jens Haas, who will sit on the executive board of Credit Suisse (Switzerland) and of SUB.
