Domestic Stability Buffer Announcement
OSFI Superintendent Peter Routledge to Announce Domestic Stability Buffer Update on June 19
Anonymous
Canada's financial regulator will announce its latest decision on the Domestic Stability Buffer (DSB) on June 19, 2026. Peter Routledge, the Superintendent of Financial Institutions, will make the call at 10:00 a.m. ET via a Zoom briefing. The DSB is the capital cushion that Canada's six biggest banks must hold to absorb losses during a financial crisis.
The announcement arrives at a tense moment. Canada has slipped into a technical recession after two straight quarters of negative growth. At the same time, the DSB has sat at a record-high 3.5% for 31 months — and pressure is building to cut it.
What the DSB Is and Why It Matters Now
The Domestic Stability Buffer forces Canada's largest banks — RBC, TD, BMO, Scotiabank, CIBC, and National Bank — to hold extra capital on top of normal requirements. Right now, those banks must maintain a minimum Common Equity Tier 1 (CET1) ratio of 11.5%. In plain terms, that is the share of a bank's own money it must keep on hand versus the risky loans it makes.
The tool has only been used as a rescue lever once before. On March 13, 2020, OSFI slashed the buffer from 2.25% to 1.00% to free up cash for pandemic lending. A cut this time could unlock a similar flood of capital. Routledge has said banks could lend an extra $1 trillion if they drew down their buffers.
A Split Advisory Council and a Stalled Economy
Just two weeks ago, the C.D. Howe Institute's shadow council of bank economists voted 4–3 to keep the DSB at 3.5%. The minority argued that "economic conditions had worsened enough to justify a cut." Council chair Jeremy Kronick admitted the backdrop had "worsened meaningfully" but said a slim majority still favored holding steady.
The broader economy adds to the pressure. Canada's GDP shrank 0.1% in Q1 2026. The Bank of Canada held its policy rate at 2.25% on June 10 — its fifth straight hold — even as inflation climbed to 2.8%. High energy prices, linked to conflict involving Iran, have cast a stagflationary shadow over the June decision.
Banks Are Well-Capitalized but Want Room to Lend
Canada's Big Six banks are sitting on a healthy average CET1 ratio of 13.6% — well above the 11.5% minimum. That gap represents roughly $60 billion in extra capital. OSFI's own technical note from February 2026 described banks as "well-capitalized." The "hold" camp argues this cushion is exactly why OSFI should not blink.
But the banking industry wants more room to lend. A report from law firm Torys LLP in April 2026 highlighted industry calls for OSFI to "rethink prudential rules" to push more credit to small and medium businesses. Critics say Canada's capital rules are "gold-plated" compared to US and European peers and discourage lending during downturns.
How to Follow the June 19 Announcement
The briefing takes place at 10:00 a.m. ET on June 19 via Zoom. Journalists and analysts must register in advance by emailing media-medias@osfi-bsif.gc.ca.

A hold at 3.5% would keep banks cautious but safe. A cut — even a modest one to 3.0% — would immediately free up billions and send a clear signal that OSFI is willing to support growth during the recession. Markets and mortgage holders alike will be watching closely.
