Climate Emergency Scenario Officially Sidelined - May 7

The Story

Friends of Science Society issued an Open Letter to the Office of the Superintendent of Financial Institutions (OSFI) on May 7, 2026, saying a widely used climate scenario, RCP 8.5, has been officially sidelined by a climate sub-committee, according to a PR Newswire release.

The letter reports the sub-committee action and requests clarity from OSFI on scenario use in regulatory work. The PR Newswire item is the source for the claim.

Why It Matters For Your Portfolio

• May 7, 2026: Friends of Science publicly flagged that RCP 8.5 has been sidelined, RCP 8.5 being the specific scenario named in the letter, so scenario assumptions for models may be questioned.
• No market price moves or percent changes were reported in the source, so immediate trading impact is not documented in the release.
• Regulatory guidance matters for banks and insurers, so investors in Canadian financials should watch communications from OSFI and major banks such as $RY, $BNS and $TD for any policy clarification.
• The Open Letter format signals a public policy push, which could prompt follow-up statements or reviews by regulators, potentially altering risk models used for stress testing.

The Trade

Who should care: holders of Canadian financial stocks, insurers and ESG-focused funds, plus traders watching regulatory-driven volatility. The source does not report a market reaction, so exercise caution and rely on official OSFI updates.

What to watch next: OSFI responses or confirmations, any statements from major Canadian banks, and formal changes to scenario guidance or stress-testing frameworks. The PR Newswire release on May 7 is the primary source for the claim.
