East West Bank was founded in 1973 in the Chinatown neighborhood of Los Angeles to serve the financial needs of the Chinese-American community. What started as a small savings and loan with $6.2 million in assets has grown into the largest minority-owned commercial bank in the United States, with over $70 billion in assets and branches spanning California, Texas, New York, Georgia, Massachusetts, Nevada, and Washington.
The routing number 322070381 carries the 322 prefix assigned by the Federal Reserve Bank of San Francisco, reflecting the bank's California charter. This single routing number serves all East West Bank accounts regardless of branch state.
The largest minority-owned bank in the United States
East West Bank is the largest minority depository institution certified by the FDIC — a designation that carries regulatory support and community development incentives designed to ensure underserved populations have access to banking services. The bank's bilingual staff, Chinese-language banking platforms, and deep familiarity with both US and Chinese regulatory environments give it a competitive moat that larger banks struggle to replicate. For a mid-market company importing goods from Shenzhen or a family purchasing property in both San Francisco and Shanghai, East West provides a rare combination of cultural fluency and institutional banking capability.
Cross-border commerce and dual-currency services
East West operates full-service branches in China, Hong Kong, and Taiwan — a rarity for an American bank of its size. This physical presence enables services beyond standard international wire transfers: trade finance, letters of credit, foreign exchange hedging, and renminbi-denominated accounts. The bank also participates in China's Cross-Border Interbank Payment System, which provides faster settlement for RMB transactions than routing through traditional correspondent banks.
For incoming international wires, East West's SWIFT code is EWBKUS66. Domestic wire fees typically run $25 for outgoing wires; international wire fees range from $35 to $50 depending on destination and currency. Incoming wires, both domestic and international, are generally free for business account holders.
Domestic transfers and ACH
For standard domestic transactions — direct deposit, ACH payments, and bill pay — routing number 322070381 applies universally across all East West Bank account types. The bank supports same-day ACH for business accounts and offers a commercial treasury management platform for companies with high transaction volumes.
Scaling beyond a single corridor with Slash
East West Bank carved out a powerful niche by specializing in US-China commerce. Businesses that trade across multiple corridors need banking infrastructure that isn't tethered to a single geographic relationship. Slash provides a modern business banking platform with built-in expense management, virtual and physical corporate cards, and integrations with the accounting tools finance teams already use — clean, modern infrastructure that lets finance teams focus on growth instead of banking logistics.
