How this series is built

Definition

The yield, in percent, at which the Government of Canada bought fixed-rate 10-year Canada Mortgage Bonds in the primary market at a syndication. The government's purchases began at the February 2024 syndication. Its notices for 2024, 2025 and 2026 say it participates in all fixed-rate CMB syndications, buying "pursuant to orders placed with the lead underwriters", and that these orders are "completely filled".

Source

Bank of Canada, Valet group CMB_PURCH ("CMB Completed Purchases"), field CMB_PURCH_YIELD ("Yield (%)"), rows where CMB_PURCH_TERM ("Term (years)") is 10.

Calculation

Published as is by the source. Sphera Credit does not transform the values. Sphera Credit keeps the rows whose term is 10 and dates each value by its trade date (CMB_PURCH_TRADE_DATE).

Publication and dating

One value per syndication at which the government bought 10-year bonds, dated by trade date. The Bank announces purchases after each syndication. There are no values between syndications.

Caveats

  • A syndication can sell more of a bond first issued at an earlier syndication: the same ISIN, coupon and maturity then appear on more than one trade date. So not every value is for a new bond.
  • The series starts with the February 2024 syndication, when the government's purchases began. For a daily value between syndications, cmb-10y-estimate gives a Sphera Credit estimate.

Use this data

Use with your AI assistant

Connect Sphera Credit Data to your assistant once. It can then chart and analyze these series, and every value it quotes carries its source and date. The catalogue is open. Pulling a history asks you to sign in with your work email, and access is free.

Copy the prompt below and paste it into your AI assistant. The assistant adds the Sphera Credit Data connector for you, or walks you through the steps when it cannot.

Prompt for your AI assistant

Add the Sphera Credit Data MCP server to this assistant, so you can answer my questions with Canadian rate data from the Bank of Canada.

Server name: Sphera Credit Data
Server URL: https://data.spheracredit.com/mcp
Type: remote MCP server over HTTP with OAuth sign-in. It needs no API key.

More information about the tools, the data series and Sphera Credit is on this page:
https://www.spheracredit.com/en/resources/data/mcp
Browse it first, so you understand what Sphera Credit is and how this server helps me. If you cannot browse the web, continue without it.

I came from the page of the series 10-year CMB, yield at syndication (series id: cmb-10y-new-issue-yield). Once you are connected, start with this series.

Then follow these steps:
1. If you can add MCP servers yourself, add this one now. Tell me what you change.
   - Claude Code: claude mcp add --transport http sphera-data https://data.spheracredit.com/mcp
   - Codex: codex mcp add sphera-data --url https://data.spheracredit.com/mcp
   - Any other tool: use your own way to add a remote HTTP MCP server with the URL above.
2. If you cannot add it yourself, tell me how to add it in this app, one numbered step at a time, with the exact URL above. If you are not sure of the steps for this app, use the steps on the page above. Do not guess a different URL.
3. The first time you pull a rate history, a sign-in page opens. I sign in myself on that page. Do not enter my details or the emailed code for me.
4. When it is connected, call list_series to check that it works. Then tell me in two or three sentences what you can now do for me. Always give the source and the date of each value you quote.

Then ask: “Chart cmb-10y-new-issue-yield since 2024 and explain how it is calculated.”
