# Who are the key customers and suppliers of OCBC?

# OCBC (O39 SP) — Key Customers and "Suppliers"

**Important framing note:** OCBC is a bank, not an industrial company. It does not have "suppliers" in the conventional sense (no input cost-of-goods, no key vendor supply chain that drives the business). For a bank, the closest analogues are:

- **Customers** = the segments OCBC lends to, gathers deposits from, and provides wealth/insurance products to.
- **"Suppliers"** = the funding base (depositors, wholesale funding) plus capital markets counterparties, technology partners, and equity affiliates that feed product/revenue.

Below is what the public disclosures and earnings calls reveal about each.

## 1. Key Customers — by segment

OCBC manages its franchise through **three core customer pillars: Corporate/Institutional, Consumer/Premier, and SME**, supplemented by a **dedicated Private Banking arm (Bank of Singapore)** and an **Insurance affiliate (Great Eastern)**.

### A. Corporate & Institutional Banking — the largest loan book
The corporate segment is the dominant driver of OCBC's SGD 341 billion loan book, which grew 9% YoY in FY2025, "contributed by both corporate and consumer segments" [1]. Management identifies these as the primary target corporate verticals:

| Sector vertical | Strategic positioning |
|---|---|
| **Sustainable financing** | SGD 56.5bn loan book = 17% of total group loans [1] |
| **TMT / Digital infrastructure / Data centres** | Named growth target sector [1] |
| **Transport & project finance** | Long-term rate hedging for infrastructure [3] |
| **Singapore residential mortgages** | Core consumer book anchor [1] |
| **EV, battery, life sciences, telco 5G, agritech, food/green** | Cross-region target sectors [9] |
| **Government-related entities (Singapore)** | Cash-management mandates and float-gathering [5] |
| **Chinese & ASEAN MNCs in the ASEAN–Greater China corridor** | Hub-and-spoke model via Singapore + Hong Kong twin hubs; Greater China loans expanded 12% since end-2020 [9] |

### B. Consumer & Premier Banking
- **Mass retail and premier clients** across Singapore, Malaysia, Indonesia (Bank OCBC NISP), Hong Kong/Macau (OCBC Wing Hang), and China.
- Singapore residential mortgages are explicitly OCBC's "biggest mortgage market" [1].
- Digital onboarding allows mass account acquisition: "98% of SME accounts were opened online" with similarly low-friction consumer onboarding [6].

### C. SME Banking
- Distinct go-to-market via digital channels — emerging-business banking, instant-approval SME loans, and online account opening built around speed [5][6].
- SMEs are explicitly cited as a focus for deposit-gathering ("more SME accounts… leading in a way also to a higher CASA percentage") [6].

### D. Wealth Management — Private Banking & Premier
This is the fastest-growing customer franchise:
- **+25% YoY** in wealth management fees [3].
- AUM up **11% YoY** with **SGD 9 billion of net new money in 1H** (SGD 5bn Q1 + SGD 4bn Q2) [4].
- Net inflows seen across **private banking, premier private clients, and premier banking** segments (e.g., a SGD 10bn quarterly inflow disclosed in a prior period) [10].
- Delivered via **Bank of Singapore** (the private banking subsidiary) — actively cross-selling to **SME owners** acquired through the Wing Hang franchise in Hong Kong [8].

### E. Insurance Customers — Great Eastern (OCBC's listed life-insurance affiliate)
- Great Eastern contributes ~10% YoY higher profit and is a captive product channel for bancassurance across OCBC's consumer base [3].

## 2. Key Geographic Customer Markets

OCBC's "Twin-Hub" structure organizes customer flows along the **ASEAN ↔ Greater China corridor** [9]:

| Hub / Market | Customer focus |
|---|---|
| **Singapore** | Mortgages, government-linked cash management, SMEs, premier wealth |
| **Hong Kong / Macau (OCBC Wing Hang)** | SME owners, GBA cross-border wealth, Bank of Singapore HK clients [8] |
| **Mainland China** | Greater Bay Area Wealth Management Connect inflows/outflows [7] |
| **Malaysia (OCBC Malaysia)** | Mortgages, SME, ASEAN MNCs |
| **Indonesia (Bank OCBC NISP)** | SME, consumer, Chinese inbound investment clients |

## 3. "Suppliers" — what feeds OCBC

For a bank, the "supplier" question maps to four real input categories:

### A. Depositors = OCBC's true "suppliers" of funding
This is the largest and most strategically managed input:
- **Customer deposits = SGD 428 billion**, +10% YoY in FY2025; 80% of total funding [2].
- **CASA deposits up 14% YoY** "across corporate SME as well as consumer segments"; CASA ratio reached **50.7%** vs. ~mid-40s prior [2].
- Liability mix is the explicit competitive lever — OCBC reshaped the balance sheet to win cash-management mandates and operating accounts (which drop directly into CASA) [5][6].

### B. Wholesale & Capital Markets Counterparties
- Senior debt, covered bonds, AT1/Tier 2 issuance — used opportunistically; OCBC remains predominantly deposit-funded (80%) [2].
- Capital markets desk also distributes structured products, FX hedges, and rate-hedging derivatives to corporate clients (these counterparties are both "suppliers" of product wrappers and customers of liquidity) [3].

### C. Internal / Affiliate Product Suppliers
- **Great Eastern** supplies insurance/bancassurance products to OCBC's bank channel [3].
- **Bank of Singapore** supplies private-banking-grade product shelf (structured products, alternatives, FX) to OCBC's wealth clients [10].
- **Lion Global Investors** supplies funds/managed solutions.

### D. Technology, Infrastructure & Service Vendors
OCBC does not publicly disclose IT/operations vendor concentration, but the call commentary repeatedly references investment in **digital channels, RM tooling, and a unified wealth platform** that powers SME and consumer onboarding — implying material spend with cloud, core-banking, and digital infrastructure providers (not individually named in disclosures) [6].

## Summary Table

| Bucket | Key constituents |
|---|---|
| **Lending customers** | Corporates (sustainable fin., TMT, transport, real estate), SMEs, Singapore mortgage borrowers, ASEAN-Greater China MNCs [1][9] |
| **Deposit "suppliers"** | Retail CASA depositors, SME operating accounts, corporate cash-management clients, Singapore GLCs [2][5] |
| **Wealth customers** | Bank of Singapore HNW/UHNW clients, Premier Private Clients, Premier Banking mass-affluent [3][4][10] |
| **Insurance customers/channel** | Great Eastern policyholders (bancassurance cross-sell) [3] |
| **Geographic anchor markets** | Singapore (core), Malaysia, Indonesia (NISP), Hong Kong/China (Wing Hang + Bank of Singapore HK) [8][9] |
| **Cross-border flow source** | Greater Bay Area Wealth Management Connect; ASEAN ↔ Greater China corridor [7][9] |

**Bottom line:** OCBC is not a supply-chain business. Its "key customers" are best understood as four overlapping segments — **corporate (incl. sustainable finance, TMT, real estate), SME, consumer/mortgage, and wealth (Bank of Singapore + Premier)** — sitting on a deposit-funded balance sheet where the **depositors themselves (especially CASA from SMEs and corporates) are the structural "suppliers"** that underwrite the bank's NIM.
