One of the biggest financial scandals of the modern era is entering a new phase. More than a decade after the key events surrounding Malaysia’s 1MDB fund, the legal consequences are increasingly reaching major international banks.

The British financial magazine The Banker published an analysis on September 17, 2026, titled “Net closes in on banks as 1MDB lawsuits escalate”, pointing out that the circle of financial institutions facing 1MDB-related disputes is continuing to expand.

From Financial Scandal to the Accountability of Financial Intermediaries

1Malaysia Development Berhad — better known as 1MDB — was Malaysia’s sovereign investment fund. U.S. and other international investigations have examined the movement of money from the fund for years, and according to figures reported by Reuters, approximately $4.5 billion was unlawfully misappropriated between 2009 and 2014.

However, the current lawsuits raise a broader question: to what extent can banks be held responsible for their clients’ transactions when there are indicators that should trigger anti-money-laundering systems, customer due diligence, and enhanced transaction monitoring?

For precisely this reason, the 1MDB case is no longer merely a story about one fund or the individuals who managed it. It is becoming an important international test of financial-institution accountability.

DBS Faces Claim Exceeding $1 Billion

One of the latest proceedings has been brought against Singaporean bank DBS.

Liquidators of four companies have filed a lawsuit seeking approximately US$1.03 billion, or S$1.298 billion, in alleged damages connected with 1MDB-related transactions.

DBS strongly rejects the allegations and has said it intends to defend itself vigorously. The bank has also stated that, following consultation with legal advisers, it has not determined that provisions are necessary at this stage in relation to the claim.

This is an important legal distinction: the filing of a lawsuit does not mean that the bank’s liability has been established. The allegations and any potential liability remain matters for the competent court to determine.

Standard Chartered Also in Legal Battle

The DBS case is not isolated. Standard Chartered is already facing a separate 1MDB-related dispute involving alleged losses of more than $2.7 billion. According to reports from Singapore, the High Court there rejected the bank’s attempt in June to have the case dismissed.

The focus is therefore increasingly shifting from the immediate participants in the fraud toward the financial infrastructure through which the money moved.

JPMorgan Paid $330 Million

The scale of the financial risk is perhaps best illustrated by the example of JPMorgan.

In 2025, the bank agreed to pay $330 million to Malaysia to resolve existing and potential claims connected with 1MDB. The settlement was reached without an admission of liability, and the funds were intended for Malaysia’s Assets Recovery Trust Account.

In a separate proceeding, Swiss authorities imposed a penalty of approximately $3.7 million on JPMorgan’s Swiss unit, citing deficiencies in organizational measures designed to prevent money laundering.

What Does the 1MDB Case Mean for Modern Banking?

The most important consequence of this case may not be the amount of any individual damages award.

The much more significant question is the standard of conduct expected of banks.

Modern compliance can no longer be viewed merely as an administrative obligation. KYC (Know Your Customer), AML (Anti-Money Laundering), identifying the beneficial owner, monitoring unusual transactions, understanding the source of funds, and continuously assessing risk are becoming part of the financial institution’s fundamental economic protection.

A single transaction that a bank fails to analyze properly can, years later, develop into a regulatory proceeding, a billion-dollar lawsuit, and a serious reputational problem.

A Lesson That Also Matters for Our Region

Although 1MDB happened thousands of kilometers away from Bosnia and Herzegovina, its message is universal.

As domestic companies and financial institutions become increasingly connected to international capital, banks, investment funds, factoring companies, and cross-border transactions, the quality of risk-management systems becomes just as important as the ability to generate profit.

The most expensive compliance is the compliance that was not done in time.

Standard Plaza is envisioned precisely as a place where finance, law, accounting, technology, and business consulting meet. The 1MDB case shows why these disciplines can no longer be viewed separately in modern business.

A major transaction today requires simultaneous understanding of capital, contracts, taxation, regulatory risk, the source of funds, and the reputation of all parties involved.

This is no longer merely a matter of compliance.

It is a matter of protecting the company’s value.
