Intelligence brief
The whole picture in one grounded read: observed macro indicators, the derived macro-sentiment composite, the business-cycle regime, and a forward forecast. Derived reads interpret already-observed numbers; the forecast is labelled projections (not observations); an absent series is shown honestly, never fabricated.
Brief
Observed macro, derived sentiment, the business-cycle regime, and forward projections — each traced to the live series it reads. Need it as JSON? GET /api/v1/brief/country/{iso3}.
Sierra Leone: macro conditions look balanced (pressure 40/100); the economy is in expansion; 1 turning-point signal flagged; 16 observed macro indicators held; real gdp growth is projected at 4.51 for 2026.
Macro pressure
DerivedHigher = more macro pressure. Reads as balanced (sentiment +0.20, −1 stressed … +1 supportive).
Outlook 2026: supportive (projected sentiment +0.56) · a projection from baseline forecasts
