## đź“‹ EXECUTIVE OVERVIEW
This project implements a **quantitative energy finance and fiscal policy model** tracking the transmission of global crude oil volatility to Kenya's local pump prices and government subsidy sustainability. It combines:
- **Global crude price modeling** (Brent indices with 3 embedded geopolitical shocks)
- **Currency transmission mechanics** (USD/KES exchange rate correlated with oil moves)
- **EPRA pricing formula engine** (synthetic pump price generation under 3 VAT scenarios)
- **Fiscal subsidy runway analysis** (KSh 945M PDL fund depletion trajectory)
- **Transport sector strike risk modeling** (Nairobi matatu fare elasticity across 3 routes)
- **Consumer purchasing power erosion** (inflation spillover from fuel → food prices)
**90-Day Simulation Period (July 14 – October 13, 2026):**
- Brent crude range: $82–115/barrel
- USD/KES depreciation: 130–145 KES/USD
- Subsidy survival status: Runway through Day 90 (critical by mid-August)
- Matatu strike risk: High volatility in Days 40–60 and 75–90
- Consumer cost impact: Transport budget increases 8–12% in worst-case scenarios

## 🔬 SECTION 1: GLOBAL CRUDE MARKET DYNAMICS
### 1.1 Brent Crude Price Path
The model generates a **90-day Brent crude trajectory** with 3 discrete geopolitical shocks embedded to reflect real-world crisis scenarios:
**Base Parameters:**
- Starting price: $88/barrel (historical average July 2026)
- Daily volatility: 2% (log-normal random walk)
- Realistic range: $82–115/barrel
**Embedded Geopolitical Shocks:**
| Day | Event | Impact | Rationale |
|-----|-------|--------|-----------|
| **15** | USA-Iran Tension Escalation | +$12/barrel | Regional conflict triggers Hormuz concerns |
| **50** | Hormuz Shipp …
