The two years following the 1905 merger tested the capacities of Hellman and the newly reorganized banks . The 1906 San Francisco earthquake and fire destroyed most of the city 's business district , including the Wells Fargo Nevada National Bank building . However , the bank 's vaults and credit were left intact and the bank committed its resources to restoring San Francisco . Money flowed into San Francisco from around the country to support rapid reconstruction of the city . As a result , the bank 's deposits increased dramatically , from $ 16 million to $ 35 million in 18 months
