How to monitor monetary policy execution with your AI

Connect your AI to the central bank data. Once it's live, your agent can calculate the spread between target rates and actual market movement.

Short answer

How can I track the difference between the Selic target and the daily effective rate?

Your AI pulls the target Selic rate and the daily effective rate to calculate the spread. You get a clear view of how closely the market is following the central bank's target. This breakdown shows you exactly how the AI handles the data.

The outcomes

What you get from the analysis

The AI processes raw central bank data into these specific results.

SPREAD

Target vs. Effective gap

The AI compares the official Selic target against the daily effective rate. You see exactly how much the market is deviating from the policy goal.

TRENDS

Rate movement tracking

Your agent looks at historical daily rates to identify if the effective rate is drifting away from the target over time.

DATA

Clean policy metadata

The AI pulls the specific parameters and target definitions from the central bank. This ensures your calculations use the correct official benchmarks.

HUMAN

Policy decision support

The AI identifies the mathematical gaps, but you decide how these deviations impact your specific portfolio or economic model.

The workflow

What your AI does when the data arrives.

The AI moves from raw data retrieval to specific spread analysis.

  1. Fetch policy targets

    The AI pulls the official Selic target and relevant metadata to establish the baseline for comparison.

    get_selic_meta

  2. Retrieve daily rates

    The agent pulls the actual effective daily rates to see what is happening in the market right now.

    get_selic_diaria

  3. Calculate the spread

    Your AI subtracts the daily effective rate from the target rate to find the execution gap.

    get_selic_diaria

  4. Report deviations

    The agent summarizes whether the market is overshooting or undershooting the central bank's target.

FAQ

How this task behaves

  • 01

    Can the AI change the Selic rate?

    No. The AI only reads data from the central bank. It cannot influence or change monetary policy.

  • 02

    Does the AI provide investment advice?

    No. The AI provides the mathematical difference between rates, but you are responsible for all financial decisions.

  • 03

    Can I get the rates for any country?

    No. This specific connector is built for Brazilian central bank data.

  • 04

    How often is the daily rate updated?

    The AI pulls the most recent data available through the get_selic_diaria tool.

  • 05

    Can the AI create a spreadsheet of these rates?

    The AI can format the data into a table for you to copy, but it cannot directly write files to your local hard drive.
