Singapore financial institutions, and the vendors that serve them, are often asked how they meet MAS technology risk rules. If you run IT or security for a regulated firm, the rules can look like a long list of documents. This guide explains the main pieces in plain words and where a managed provider can help.

What MAS TRM is

MAS TRM stands for the Monetary Authority of Singapore (MAS) Technology Risk Management Guidelines. MAS published them on 18 January 2021. They help financial institutions set up sound technology risk governance and oversight, and keep their IT and cyber systems resilient.

The Guidelines cover a broad group of regulated firms, including banks, insurers, capital markets firms and payment institutions. Check the MAS page to see how they apply to your licence type.

The 2021 update also added a section on cyber security operations (monitoring, threat intelligence, incident response) and measures to test your defences, such as adversarial attack simulation, according to a Kroll review of the 2021 Guidelines.

Guidelines and notices are not the same thing

Many teams mix these up, so it helps to separate them.

Guidelines describe good practice. MAS TRM is one of them.

Notices are binding requirements. MAS issues them by type of institution.

In May 2024, MAS published a Notice on Technology Risk Management (for example, Notice FSM-N03 for insurers). Ten earlier technology risk notices, including Notice 644, were cancelled from 10 May 2024. If you still cite Notice 644 in policies or vendor questionnaires, update it.

MAS also issues cyber hygiene notices. For example, Notice FSM-N22 for capital markets institutions sets requirements on securing administrative accounts, applying security patches, setting baseline security standards, using network security devices, anti-malware measures and stronger user authentication.

Incident reporting: what changed

On 16 December 2025, MAS issued a circular on financial institution incident reporting. From 1 February 2026, firms submit reportable incidents using a revised template on the MAS-FI Transactions Platform (MAS-Tx).

The circular says to notify MAS as soon as possible, but no later than the timeline in the notice or rule that applies to your firm. That timeline depends on your institution type, so read your own notice before you set your internal playbook.

Other Singapore laws that may apply

Law firm reviews give two more points to keep in mind. These come from legal commentary, not from the MAS or PDPC pages, so confirm them with your legal team.

PDPA: From 1 October 2022, the maximum financial penalty is S$1 million or, for organisations with annual turnover above S$10 million, 10% of annual local turnover, whichever is higher (CMS).

Cybersecurity Act: It first focused on critical information infrastructure (CII) owners. A 2024 amendment, passed on 7 May 2024, widened its scope to cover more types of digital infrastructure and third-party systems (Norton Rose Fulbright).

Where mid-sized teams get stuck

Most gaps come down to ownership and records, not new tools. Four common ones are: nobody has mapped each control in the Guidelines and notices to a named owner; patch and access records sit in different tools, so evidence takes days to collect; out-of-hours monitoring depends on one or two people; and vendor and third-party checks are done once a year and then forgotten.

A simple way to start

Step 1. List your critical systems and who owns each one.

Step 2. Check which MAS notice applies to your institution type.

Step 3. Compare your current controls with the cyber hygiene areas above, and mark the gaps.

Step 4. Write your incident reporting steps, including who files in MAS-Tx.

Step 5. Keep evidence (patch records, access reviews, test results) in one place and review it each quarter.

This order keeps the work small and gives you evidence as you go.

Frequently asked questions

What is MAS TRM?

It is the MAS Technology Risk Management Guidelines, published on 18 January 2021. They set out good practice for technology risk governance and IT resilience at financial institutions.

Is MAS TRM mandatory?

The Guidelines describe expected practice. MAS also issues binding notices on technology risk and cyber hygiene, by institution type. Check which notice applies to your firm.

Can a managed provider outside Singapore help with MAS TRM?

Yes, for monitoring, identity controls, testing and evidence collection. Your own staff still own the accountability, and you should check your outsourcing and third-party rules before you sign.

Key takeaway

Know which MAS notice applies to you, keep your incident steps ready for MAS-Tx, and keep your evidence in one place.
