Understanding Forecast Revisions and Credibility
Here’s a truth about forecasts: they change. BNM revises their inflation outlook every quarter based on new data. That’s not a failure. That’s how credible forecasting works.
But the revisions themselves are informative. If BNM consistently overestimates inflation, their credibility suffers. Markets will discount their forecasts. If they revise too frequently with large swings, that signals poor modeling or high uncertainty. Stable, small revisions? That suggests good judgment and reliable methodology.
Watch the track record. Over the past 8 to 10 quarters, did BNM’s forecasts prove accurate? Were the confidence intervals reasonable? Did they flag turning points in advance? A central bank that gets the big picture right — even if quarterly numbers vary — deserves trust. That trust is essential. When people believe BNM will keep inflation stable, inflation expectations stabilize. That becomes self-fulfilling.
