    {
      "heading": "Perils of commitment",
      "content": "- During the low-inflation era after the global financial crisis, communication was dominated by forward guidance centered on precommitting to a likely future path of the policy rates.\n- Such commitments can be effective when policy is stuck at the lower bound and inflation expectations are drifting down.\n- Commitments may become costly when circumstances change (supply shocks, inflation surprises, abrupt shifts in the balance of risks) and may require policymakers to adjust course.\n- Result: Central bank communication has shifted toward explaining how policy will respond as economic conditions evolve and new data become available."

      "heading": "Understanding reaction functions",
      "content": "- Central task: Communicating the reaction function—how policymakers interpret incoming data, weigh risks, and navigate tradeoffs between key central bank objectives.\n- Key inputs to the reaction function:\n  - The strength of underlying inflation\n  - The evolution of inflation expectations\n  - The nature of monetary policy transmission\n- Emphasis on “Data dependence”: central banks explain what data matter, how data shape decisions, and what future contingencies may mean.\n- Goal: Help the public understand the logic that guides a central bank’s decision-making."
    },
    {
      "heading": "Explaining risks and uncertainty",
      "content": "- Central banks convey views on the economic outlook through forecasts and scenarios because policy decisions are based on where the macroeconomy is expected to go.\n- Forecasts are not promises: in a shock-prone world, forecasts are subject to tremendous uncertainty.\n- If forecasts are communicated too precisely, or policy-rate projections are interpreted as commitments, revisions can be misinterpreted as policy reversals.\n- Scenarios can:\n  - Illustrate how policy might respond under different economic outcomes\n  - Reinforce that future decisions will depend on incoming data and evolving conditions"
    },
    {
      "heading": "Communication for a shock-prone world",
      "content": "- Forecasts should be accompanied by a clear explanation of risks.\n- Effectively communicating the reaction function helps the public understand how policy may respond under alternative economic outcomes.\n- Rate-path commitments should be exceptional and conditional, with clear escape clauses so that any conditional promise is clearly subordinate to the price-stability mandate."
    },
    {
      "heading": "More isn’t always better",
      "content": "- Clear communication can anchor expectations and support accountability.\n- But more communication is not always better.\n- Rapid parsing of messages via social media, automated news analysis, and artificial intelligence means communications are parsed in real time.\n- Too much detail can lead markets to focus excessively on decoding the central bank rather than assessing fundamentals.\n- Hence conditionality relative to the evolving outlook is foundational."

    {
      "heading": "Volatility’s value",
      "content": "- The goal of central bank communication is not to eliminate volatility but to reduce uncertainty about how the central bank will respond, limiting surprises around policy decisions.\n- Volatility itself is not undesirable when asset prices move in response to new information about incoming macroeconomic data that shape the inflation and growth outlook.\n- Such volatility fosters the information content of expectations and can provide information to policymakers."

      "heading": "Speaking with humility",
      "content": "- Successful communication depends on fostering a better understanding of the policy framework.\n- Central banks should be clear about:\n  - Objectives\n  - The reaction function\n  - Forecasts\n- Given the high degree of uncertainty globally, central banks need to be explicit about risks, with the goal of reflecting the degree of underlying macroeconomic uncertainty accurately.\n\nSource: Rethinking Central Bank Communication in an Uncertain World, Tobias Adrian, August 26, 2026.\n\n---\n\n\n References\n\n- IMF note\n\nSource: https://www.imf.org/en/blogs/articles/2026/08/26/rethinking-central-bank-communication-in-an-uncertain-world"
