Epic Fury Ends, But Brent $108 Still Hits Indonesia’s $4.1B Budget — And ASEAN’s

Subtitle:

US ends Operation Epic Fury May 8. Brent drops 9% from $115 peak. For Indonesia, that’s Rp66 trillion freed from emergency subsidies. But 3 days of calm ≠ peace for ASEAN fiscal math.

Lead :

US declared Operation Epic Fury over May 8, 2026. 72 hours later, Brent crude slid to $108, down 9% from May 5 war peak $115. Markets exhale.

For Indonesia, that 9% drop rewrites 2026 budget math. Every $1 Brent fall = Rp15.2 trillion saved on fuel subsidies per BKF Ministry of Finance. $7 drop = Rp106 trillion potential saving. But Jakarta only gets Rp66 trillion because subsidies were already capped.

3 days of ceasefire isn’t peace. Barclays sees Brent $100 if Hormuz stays blocked, $110 if disruptions run through May. ASEAN’s largest oil importer is still exposed.

1. The $4.1B Number: Why Brent $108 = Rp66 Trillion APBN Space

Indonesia pegs 2026 APBN oil price at $100/bbl per draft KEPPRES APBN 2026. Subsidy formula: if Brent >$100, government pays difference to keep Pertalite Rp10,000/L + Solar Rp6,800/L.

May 5 peak $115 = $15 above assumption = Rp228 trillion emergency subsidy risk per BKF. May 11 Brent $108 = $8 above assumption = Rp122 trillion risk.

Math: Rp228T - Rp122T = Rp106T theoretical saving. But APBN already budgeted Rp60T for subsidy + Rp40T for compensation. Real “fiscal space” freed = Rp66 trillion that Jakarta doesn’t need to spend.

So What: That Rp66T can shift to 3 urgent items: 1) IKN infrastructure, 2) free school meals expansion, 3) buffer for rupiah defense if BI needs to raise rate. Oil de-escalation = budget flexibility.

2. Market Split: MEDC vs GIAA Shows ASEAN’s Two-Face Risk

Oil price fall doesn’t hit all stocks equally. IDX data May 7-11 proves it:

MEDC -7.3%: Medco Energi gets 62% revenue from oil. Brent $108 vs $115 = profit forecast cut $180M 2026 per Mirae Sekuritas. Investors price “peace = lower upstream margin”.

GIAA +74%: Garuda Indonesia flies 70% domestic routes with jet fuel 34% of cost. Brent $108 vs $115 cuts fuel bill ~Rp4.2T/year. Plus US-Iran de-escalation = fewer flight route detours + lower insurance premium.

Rupiah Rp17,378 on May 10: Seems strong vs peak Rp17,856. But oil import cost still bleeding: Indonesia imports 380K bpd per ESDM 2026. Brent $108 = $15B annual import vs $16B at $115. Rupiah strength can’t hide import bill.

So What: ASEAN markets split between “oil producers vs oil consumers”. Singapore airlines up, Petronas flat, Thai Airways up 18%. One region, two P&L stories.

3. The Hormuz Catch: Barclays $100 vs $110 Scenario

3 days without Epic Fury bombing ≠ Strait of Hormuz open. Barclays Commodities Update May 11, 2026 maps 2 scenarios:

1.       Scenario A $100 Brent: If Iran + US keep ceasefire + Hormuz stays 20% blocked, not closed. Risk premium drops from $15 to $8. Indonesia saves Rp66T but must watch Q3 demand spike.

2.  Scenario B $110 Brent: If disruptions run through May + 1 tanker hit, risk premium stays $18. Indonesia subsidy risk jumps back to Rp180T. That wipes out Rp66T saving in 2 weeks.

Data:21M bpd oil flows through Hormuz = 20% global supply per EIA. Indonesia takes 0 bpd directly from Hormuz but global price sets Pertamina import cost.

So What: 3 days calm is trading noise, not fiscal policy. Finance Minister Sri Mulyani must budget for $110, hope for $100. “Ceasefire accounting” is dangerous for APBN.

4. ASEAN Domino: Singapore, Thailand, Malaysia Feel It Too

Indonesia isn’t alone. Epic Fury ripple hits all ASEAN oil importers:

1.       Singapore: Jet fuel hub. Brent $108 vs $115 = Changi Airport fuel cost down 6%. SIA + Jetstar Asia margin up. But Singapore OSAT + data centers need stable power price. Oil volatility = electricity price risk.

2.       Thailand: Subsidizes diesel B7 at 29.94 baht/L. Brent $108 saves Bangkok ∼$2.1B 2026 vs $115 scenario per Thai Ministry Energy. But baht at 36.8/USD means import cost still high.

3.     Malaysia: Net oil exporter. Brent fall hurts Petronas dividend to government. 2026 budget assumed $105 Brent. $108 = okay, but $100 = RM8B revenue gap. ASEAN “oil importer vs exporter” divide widens.

So What: No ASEAN country escapes Epic Fury math. Importers get fiscal room, exporters lose revenue. Neutral Tech Corridor and energy security = fiscal security.

5. CTA: 3 Moves Jakarta Must Make Before June 2026 

Brent $108 window won’t last if Hormuz escalates again. Finance Minister + Commission XI DPR must act before June 2026 APBN revision:

1.       Move 1: Lock Rp66T into “Epic Fury Buffer Fund”

Don’t spend saving on populist programs. Park Rp66T in separate account at DJPPR. Use only if Brent >$115 again. This prevents 2018 repeat: oil fell, subsidy saved, then spent on elections.

2.       Move 2: Accelerate BBM One Price + EV conversion

Use saving to expand Pertashop in 3T region + subsidize electric motorbike swap 300K units 2026. Every 100K EV swap cuts oil import 5K bpd = $197M saved at Brent $108.

3.       Move 3: Hedge 30% oil import via long contract 

Task Pertamina + SKK Migas to lock 30% of 2026 import at $105 via futures. If Brent jumps to $130, budget safe. If Brent falls to $90, Indonesia still pays $105 but gets price certainty.

Bottom line: Epic Fury ended May 8. But Indonesia’s oil risk didn’t. Rp66T saving is real, but only if Jakarta treats it as insurance, not income.

Bottom Line: Ceasefire Gives Budget Room, Not Energy Security 

Operation Epic Fury stop = Brent $108 = Rp66 trillion APBN space. That’s $4.1B breathing room for Indonesia 2026. MEDC down, GIAA up proves market already priced it.

But Barclays $100-$110 range + Hormuz 20% blockage means risk is deferred, not gone. ASEAN oil importers must use this window to cut subsidy dependence, not expand it.

For Indonesia, the lesson is fiscal: peace is temporary, but budget math is permanent. Treat Brent $108 like a discount coupon with expiry date.

Key Numbers to Watch:

- Brent $108 vs APBN assumption $100 

- Rp66 trillion fiscal space freed 

- Hormuz 21M bpd = 20% global oil 

- June 2026 APBN revision deadline
