Bitumen Inventory Level
Last updated: 2026-10-08
Bitumen Inventory Level
Global bitumen inventory levels stood at approximately 3.1 million metric tons across major export hubs (Singapore, Korea, Middle East, and Europe) as of Q1 2024, representing roughly 28–32 days of forward supply at current consumption rates. Bitumen prices from key exporters like Singapore and Iran currently range between $420–$480 per metric ton FOB, with inventory levels directly influencing these prices within a 5–8% band. Below is a detailed breakdown of inventory dynamics by region, grade, and season.
What Is Bitumen Inventory Level and Why It Matters
Bitumen inventory level refers to the total volume of bitumen stock held in tanks, terminals, and refineries at any given point in time. It is a critical metric for traders, road construction companies, and importers because it directly affects:
- Spot pricing — Low inventory pushes prices up 10–15%; high inventory suppresses them.
- Lead times — Tight inventory can extend delivery windows from 7 days to 25+ days.
- Shipping economics — Bulk vessel utilization ranges from 60% to 95% depending on stock availability.
- Contract negotiations — Buyers with inventory visibility negotiate 3–6% better terms.
| Metric | Value | Change vs Q4 2023 |
|---|---|---|
| Global hub inventory | 3.1 million MT | -4.2% |
| Days of forward supply | 30 days | -2 days |
| Singapore inventory | 780,000 MT | -6.1% |
| Korea inventory | 410,000 MT | +1.8% |
| Middle East inventory | 1.1 million MT | -3.5% |
| Europe (ARA) inventory | 560,000 MT | +2.4% |
| Average FOB price (penetration grade 60/70) | $455/MT | +3.1% |
Inventory below 25 days of supply typically signals a shortage and triggers price spikes of $20–$40 per MT within 2–3 weeks.
Regional Bitumen Inventory Level Comparison
Inventory levels vary significantly by region due to refining capacity, export demand, and seasonal road-building cycles.
| Region | Inventory (MT) | Days of Supply | Primary Grades | Price (FOB $/MT) |
|---|---|---|---|---|
| Singapore | 780,000 | 26 | 60/70, 80/100 | $460–$480 |
| South Korea | 410,000 | 34 | 60/70, PG 64-22 | $445–$465 |
| Middle East (Iran/UAE) | 1,100,000 | 38 | 40/50, 60/70 | $420–$445 |
| Europe (ARA) | 560,000 | 29 | 50/70, 70/100 | $470–$495 |
| India (domestic) | 250,000 | 18 | VG-30, VG-40 | $485–$510 |
Key observations:
- Middle East holds the largest inventory due to high refinery output and competitive pricing (Iran, Iraq, UAE).
- India runs the tightest inventory (18 days) because of strong domestic road construction demand under the PMGSY and NHAI programs.
- Singapore is the price-setter for Asia-Pacific; its inventory drops below 700,000 MT typically trigger a $15–$25/MT price increase.
Factors That Drive Bitumen Inventory Level Changes
Bitumen inventory levels shift based on supply-side and demand-side forces. Understanding these helps buyers time purchases.
- Refinery maintenance — Turnarounds reduce output by 20–40% for 3–6 weeks, drawing down inventory.
- Crude oil prices — When Brent exceeds $85/barrel, refiners shift to higher-value products (diesel, jet fuel), cutting bitumen yield by 5–10%.
- Export quotas — Iran's seasonal quotas can add or remove 100,000–150,000 MT from global supply.
- Logistics bottlenecks — Vessel availability affects 15–20% of inventory turnover.
- Monsoon and winter seasons — In India and Southeast Asia, demand drops 30–50% from June to September, raising inventory.
- Government infrastructure spending — A 10% increase in road budgets typically absorbs 200,000–300,000 MT within a quarter.
- Price speculation — Traders holding stock can artificially tighten inventory by 5–10%.
| Inventory Level (Days of Supply) | Market Condition | Typical Price Movement |
|---|---|---|
| Below 20 days | Critical shortage | +$30–$50/MT |
| 20–25 days | Tight | +$10–$30/MT |
| 26–35 days | Balanced | ±$5/MT |
| 36–45 days | Comfortable | -$5–$15/MT |
| Above 45 days | Oversupplied | -$15–$35/MT |
How to Track Bitumen Inventory Levels for Better Buying
Buyers who track inventory gain a 3–7% cost advantage over those who buy reactively.
- Terminal reports — Weekly stock reports from ports like Singapore, Jebel Ali, and Rotterdam.
- Refinery data — Monthly output figures from major producers (Reliance, SK Energy, Shell, BP).
- Shipping trackers — Vessel loadings and discharges indicate real-time outflow.
- AI-based platforms — Tools like 6Tar aggregate inventory, price, and shipping data into a single dashboard.
| Week | Inventory (MT) | Price (FOB $/MT) | Notes |
|---|---|---|---|
| Week 1 | 820,000 | $455 | Stable supply |
| Week 2 | 790,000 | $460 | Minor drawdown |
| Week 3 | 745,000 | $470 | Refinery shutdown |
| Week 4 | 780,000 | $465 | New cargo arrival |
A 75,000 MT swing in inventory moved prices by $15/MT within 4 weeks — a clear demonstration of inventory-price sensitivity.
Bitumen Inventory Level Outlook for 2024–2025
Forecasts suggest inventory will remain tight to balanced, with regional exceptions.
- Global inventory projected at 2.9–3.3 million MT through 2024.
- Asia-Pacific demand expected to grow 4–6%, keeping Singapore/Korea inventory under 30 days.
- Middle East supply likely stable, with Iran exporting 500,000–600,000 MT/month.
- Europe may see inventory rise 5–8% due to slower road spending.
| Region | Q3 2024 (MT) | Q4 2024 (MT) | Trend |
|---|---|---|---|
| Singapore | 720,000 | 800,000 | Tight then easing |
| Korea | 400,000 | 430,000 | Stable |
| Middle East | 1,050,000 | 1,150,000 | Rising |
| Europe | 580,000 | 600,000 | Slight rise |
| India | 220,000 | 260,000 | Tight |
Buyers should lock in contracts when inventory falls below 25 days of supply to avoid peak pricing.
FAQ: Bitumen Inventory Level
Q1: What is the current global bitumen inventory level?
As of Q1 2024, global hub inventory is approximately 3.1 million metric tons, equal to about 28–32 days of forward supply. This is down 4.2% from Q4 2023, indicating a tightening market.
Q2: How does inventory level affect bitumen price?
Inventory and price move inversely. When supply drops below 20 days, prices typically rise $30–$50 per MT; when supply exceeds 45 days, prices fall $15–$35 per MT.
Q3: Which region has the highest bitumen inventory?
The Middle East holds the highest inventory at roughly 1.1 million MT (38 days of supply), driven by strong refinery output in Iran and the UAE. India holds the lowest at about 250,000 MT (18 days).
Q4: How often should I track bitumen inventory levels?
Weekly tracking is recommended for active buyers, as inventory can swing 50,000–100,000 MT in a single week. For contract buyers, monthly tracking combined with price alerts is sufficient.
Q5: What inventory level signals a good buying opportunity?
An inventory level of 35–45 days of supply with stable or falling prices signals a good buying window. Below 25 days, prices tend to spike, so early procurement is advised.
Conclusion and CTA
Bitumen inventory level is the single most actionable metric for timing purchases. With global stock at 3.1 million MT and prices at $420–$480/MT FOB, buyers who monitor inventory weekly can save 3–7% per order.
