Hin Leong hid $800 million in oil losses until the crash — then owed $4 billion

Hin Leong Trading was one of Asia's biggest independent oil traders, founded by Lim Oon Kuin in 1963 and built into a network of tankers, terminals and storage. By early 2020 the company owed roughly $4 billion to more than 20 banks, including HSBC, DBS, OCBC and ABN Amro.

When oil prices plunged in March and April 2020, the firm could no longer hide losses that had accumulated for years. Court filings revealed Hin Leong had concealed about $800 million in futures trading losses and used forged oil-sales documents to secure financing. The company was placed under judicial management in April 2020.

Lim Oon Kuin was later convicted of fraud and forgery, sentenced to 17.5 years in prison in 2024, and his family agreed to pay billions to creditors. The collapse shook Singapore's reputation as a commodities-trading hub and exposed how trade-finance documents can outrun the trades they claim to represent.

Hin Leong used forged oil-sales documents to secure bank financing while hiding $800 million in futures losses, leaving $4 billion in debt when the crash hit.

The company used forged oil-sales documents to obtain bank financing while hiding real trading losses.

Lim Oon Kuin directed staff to keep losses off the books rather than disclose them to lenders.

Rapid expansion into vessel chartering and storage multiplied counterparties and complexity, making concealment easier.

Banks relied on documents that looked perfect rather than verifying the underlying physical oil trades.

When financing is secured by documents alone, the document trail can become the fraud — lenders and auditors must verify the underlying asset, not just the paper.

Hin Leong was wound up; Lim Oon Kuin was declared bankrupt in 2024 and sentenced for fraud. Creditors including HSBC, DBS and OCBC faced large impairments.
