Australia’s economy runs on long supply lines. Most of our fuel arrives by ship, is refined overseas, and then moves through a tightly coordinated network of ports, depots, trucks, and regional distribution points before it ever reaches a service station or supermarket. Under normal conditions this system is remarkably reliable, which is why most people rarely think about it. But when global shipping routes are disrupted—particularly major energy corridors like the Strait of Hormuz—the question is not simply whether fuel exists somewhere in the world, but whether it can continue to arrive here smoothly and on time.

The Australia Fuel & Logistics Risk Watchboard is intended as a practical way to follow the early signals in that system: shipping flows, refinery activity, freight costs, and regional supply indicators. By watching these indicators together, it becomes easier to understand whether events overseas are simply creating price volatility, or whether the foundations of Australia’s supply chains are beginning to tighten.

Monitoring signals for supply-chain stress (Hormuz scenario)

How to read it

Each indicator has three states:

🟢 Normal

🟡 Stress building

🔴 Disruption underway

You don’t need everything to turn red.

3–4 yellows at once usually means the system is tightening.

2–3 reds means disruption is already propagating.


Global Energy Flow Indicators

1. Tanker traffic through Hormuz

Why it matters: confirms whether the chokepoint is reopening.

🟢 20+ tankers/day

🟡 10–20 tankers/day

🔴 <10 tankers/day

Signal source:

  • Kpler
  • MarineTraffic
  • Reuters shipping reports

2. VLCC tanker charter rates

Why it matters: reflects panic in tanker availability.

🟢 <$40k/day

🟡 $40–80k/day

🔴 >$80k/day

When tankers become scarce, delivery cadence collapses.


3. Brent oil price

🟢 <$95

🟡 $95–120

🔴 >$120

High prices indicate sustained supply stress.


Asian Refinery Indicators

4. Singapore diesel crack spread

Why it matters: the Asia-Pacific fuel price benchmark.

🟢 <$20/bbl

🟡 $20–35

🔴 >$35

High crack spreads mean diesel supply is tightening.


5. Asian refinery run rates

🟢 Normal

🟡 5–10% cuts

🔴 >15% cuts

Refinery cuts show crude deliveries are failing.


6. Singapore diesel inventories

🟢 stable

🟡 slow drawdown

🔴 rapid drawdown

Singapore is effectively the fuel warehouse of Asia.


Australian Fuel Supply Indicators

7. Wholesale diesel price (Australia)

🟢 < $2.10/L

🟡 $2.10–2.50

🔴 > $2.50

Sharp rises signal tightening imports.


8. Fuel terminal allocations

🟢 no allocation limits

🟡 voluntary reductions

🔴 mandatory allocation

Once terminals allocate fuel, the system is already strained.


9. Regional fuel shortages

🟢 none reported

🟡 isolated shortages

🔴 widespread shortages

Regional areas show problems weeks before cities.


Freight System Indicators

10. Truck freight fuel surcharge

🟢 <10%

🟡 10–20%

🔴 >20%

Freight operators adjust prices first.


11. Supermarket supply disruptions

🟢 normal shelves

🟡 substitutions increasing

🔴 noticeable gaps

Fresh produce is usually the earliest visible signal.


Behaviour Indicators

12. Panic buying

🟢 normal retail demand

🟡 fuel queues forming

🔴 rationing introduced

Behavioural shocks can accelerate shortages dramatically.


Infrastructure Resilience Indicators

13. AdBlue supply status

🟢 stable

🟡 supply warnings

🔴 trucking restrictions

AdBlue shortages can halt freight even with diesel available.


14. Mining output adjustments

🟢 normal production

🟡 precautionary cuts

🔴 major curtailments

Mining will reduce operations if diesel allocation begins.


Interpreting the System

Stable

Most indicators green.

Tightening

3–4 yellow signals.

Expect:

  • rising fuel prices
  • freight costs increasing
  • some volatility.

Disruption beginning

2+ red signals.

Expect:

  • regional fuel shortages
  • freight constraints
  • supermarket gaps.

Structural crisis

4+ red signals.

Expect:

  • diesel allocation
  • sector prioritisation
  • economic contraction.

Signals I Would Personally Watch Most Closely

These 5 will tell you almost everything:

1️⃣ Tanker traffic through Hormuz

2️⃣ Singapore diesel inventories

3️⃣ Asian refinery run cuts

4️⃣ Australian diesel wholesale price

5️⃣ Regional fuel shortages

When 3 of those move together, the system is tightening.
