Transition Planning: What MAS Expects From Fund Managers by September 2027

MAS has given asset managers a date. On 5 March 2026 it issued its Guidelines on Transition Planning, with an 18-month transition period. They take effect in September 2027, less than a year from now.

The Guidelines do not hand fund managers a template. They ask a different question: can you show how environmental risk, including the risk of the transition to a lower-carbon economy, feeds into how you invest and how you deal with the companies you hold?

What they are

The Guidelines are addenda to MAS's 2020 Guidelines on Environmental Risk Management for asset managers. They build on that document and do not replace it. A firm that already follows the 2020 guidelines has a base. The new text adds structure in three areas in particular: stewardship, data, and forward-looking tools such as scenario analysis.

They apply to asset managers. Managers with discretionary authority over portfolios get the most emphasis on engagement and stewardship. Check your own position against the MAS text.

What MAS expects

• Governance. The Board and senior management oversee the approach. Senior management makes sure the risk management framework shows how environmental risk feeds into areas such as investment research.
• Research and portfolio construction. Where environmental risk is material, it is built into research and portfolio construction. This allows for differences between asset classes and for limits set by clients, such as caps on fossil fuel exposure.
• Scenario analysis. Where environmental risk is material, build scenario analysis with short and long horizons. Where data is thin, qualitative assessment can fill in.
• Data. Be clear about the limits of proxy data and work to close material gaps.
• Engagement and stewardship. Have engagement plans for investee companies, starting with the most exposed, and proxy voting policies that take climate into account. Engagement can run over several years and should be stepped up where mitigation is not adequate.
• People and review. Hire or train for the skills, put a data strategy in place, and review the governance and processes regularly.

What they do not ask for

• A single template. MAS has not prescribed one format for a transition plan.
• Blanket divestment. MAS warns against pulling out of higher-risk investee companies indiscriminately, because that can add to stranded-asset risk and a disorderly transition. Managers may still sell in line with a fund's investment strategy.
• New disclosure rules. The Guidelines do not add disclosure requirements beyond those already in the 2020 Guidelines.

Applied in proportion

MAS expects the Guidelines to be applied in proportion to the size and nature of your business. Proportionate does not mean optional. You should write down the assessment behind your approach, your priorities and a roadmap, so you can show them at an inspection.

A suggested plan for the next 11 months

This is our suggestion, not a MAS requirement.

1. Compare your environmental risk policy with the new expectations. Mark each one as covered, partly covered or not covered.
2. Check the documents the Guidelines touch. Typically these are your environmental risk policy, your research and portfolio construction procedures, your stewardship and engagement policy and your proxy voting policy.
3. Write down your proportionality assessment. Which funds and sectors carry material environmental risk, and what do you do about it?
4. Take it to the Board and senior management. Agree who owns it and when progress is reported.
5. Leave time to test. Scenario analysis and data work usually take longer than the policy wording.

One more date for your calendar

Shortly afterwards, on 7 October 2027, the first sections of MAS's final AI risk management guidelines begin to apply. Two 2027 dates, two existing areas of policy to revisit.

Why this keeps happening

The pattern is common: a long lead time, a new guideline that sits on top of an existing one, and a set of policies that need to be checked against it. Most firms do not miss these dates because they did not know about them. They miss them because nobody connected the change to the right policies in time. RegRails.ai is built for that: it tracks MAS changes by effective date and shows which of your policies are affected. Visit RegRails.ai to see how.
