UOB’s Lim Lay Wah: Supplier readiness key to sustainability

Financing alone is rarely enough.

Companies are increasingly tying working capital to sustainability goals, but supply chains that can support these ambitions remain limited.

“Supply chains are complex and fragmented, sustainability capabilities among suppliers are uneven, and regulatory expectations vary across markets,” Lim Lay Wah, managing director and head of sector solutions and global financial institutions at United Overseas Bank Ltd. (UOB), told Asian Banking & Finance. “These constraints can slow progress, even when the intent is strong.”

Lim, who leads a global team of more than 160 people across 18 markets, said financing alone is rarely enough. “Sustainability efforts are most effective when grounded in sector realities and local market conditions,” she said in an emailed reply to questions.

Targeted interventions such as supplier workshops, performance frameworks, and tools for better traceability create meaningful impact, Lim added.

She oversees companies’ capital needs from funding to deployment, working with banks, funds, insurers, and corporate clients across emerging and established markets.

Lim, the only female Singaporean banker on the ASEAN (Association of Southeast Asian Nations) Business Advisory Council, also serves as a bridge between the private sector and regional policymakers. “We elevate real-world business challenges—cross-border complexities, decarbonisation readiness, and financial inclusion—into policy conversations,” she said.

Lim aims to increase institutional capital flows into ASEAN whilst using artificial intelligence (AI)-enabled tools to improve productivity, risk management, and client experience.

UOB plans to grow by enhancing cross-border trade and payments, scaling sustainable financing, and digitising trade and working capital processes end-to-end, she added.

Lim’s career began as an assistant relationship manager, where she learned the fundamentals of client service, credit discipline, and execution. She has since held leadership roles across the Asia-Pacific region and the Middle East.

“I work closely with senior leaders on finance, risk management, and corporate strategy to strengthen resilience and support long-term value creation,” she said.

She noted that greater female representation at the leadership level ensures diverse perspectives, producing more inclusive outcomes.

“In this uncertain environment, more female representation at the leadership level ensures that diverse perspectives are considered, resulting in more inclusive actions and outcomes,” Lim said.

The bank supports career development through training, upskilling, and leadership programmes, said Lim, who says success is creating value not only for clients but also for her team and the bank.

UOB has structured learning platforms like Better U and Better U Pivot for upskilling, coaching, and career transition support; and the Leadership Acceleration Programme.

Lim encouraged young professionals to build a strong technical foundation, embrace new roles, seek sponsors, and remain committed to learning.

“This mindset is what will sustain momentum and propel you forward in your career,” she added.
