How this series is built

Definition

A Bank of Canada measure of core inflation, as a year-over-year percent change. It "excludes 20 per cent of the weighted monthly price variations at both the bottom and top of the distribution of price changes, and thus it always removes 40 per cent of the total CPI basket". The excluded components can change from month to month.

Source

Bank of Canada, Valet series CPI_TRIM ("CPI-trim"), also published as Statistics Canada table 18-10-0256-01 ("Measure of core inflation based on a trimmed mean approach, CPI-trim (year-over-year percent change)").

Calculation

Published as is by the source. Sphera Credit does not transform the values. Statistics Canada computes it from Consumer Price Index component series that are seasonally adjusted and adjusted to remove the effect of changes in indirect taxes. Since the January 2024 reference month, the year-over-year change is calculated from index values rounded to one decimal place.

Publication and dating

Monthly. Each value is dated the first day of its reference month.

Caveats

  • Subject to revision, because it is based on seasonally adjusted price index series. Sphera Credit serves the Bank of Canada's current values, so past months can change.

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 CPI-trim (series id: cpi-trim). 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 cpi-trim since 2024 and explain how it is calculated.”
