ALERT LEVEL: ELEVATED (governance and policy-predictability risk; near-term market risk Low) · Indonesia · Reported Tue 29 Sep 2026, 20:51 WIB (Jakarta Post, dated 30 Sep) · House deliberations expected in October 2026

Coalition parties are proposing a rule that would require at least 2 House parties behind every presidential ticket. That could undo, through the back door, the Constitutional Court’s January 2025 ruling that let every party nominate a candidate.

1. What happened

As the House and government prepare to revise the 2017 General Elections Law before the 2029 elections, parties in President Prabowo Subianto’s coalition have proposed new rules for presidential nominations. Experts warn the proposals may breach Constitutional Court (MK) rulings meant to widen competition.

Item	Detail
Court ruling being implemented	MK ruling, 2 Jan 2025: scrapped the 20% of House seats / 25% of national vote threshold to nominate a presidential ticket; every party has the right to nominate. The House and government may regulate nominations by other means, but not via seat or vote shares
Proposal	Each presidential ticket must be backed by at least 2 parties that hold House seats
Backers	NasDem (coalition member); Golkar, via secretary-general Sarmuji, who says it follows the court order
Undecided	Gerindra (Prabowo’s party) has not stated a position
Timing	Election Law revision deliberations to start “sometime in October”, per NasDem secretary-general Hermawi Taslim (29 Sep)
Related	Party leaders began election-law talks on 18 Sep and are weighing a higher parliamentary (legislative) threshold; small parties warned in May against a last-minute revision
Critics	Election experts and civil-society groups: the 2-party rule narrows choice and may face a fresh MK challenge

2. Why it matters

Continuation and escalation of a trend, not a one-off. It is the second coalition move this month to narrow electoral competition for 2029. On 15 to 16 Sep, Gerindra, Golkar and PKS backed raising the parliamentary threshold from 4% to 5%. On 11 Sep, 7 KIM Plus leaders met at the State Palace on a 130-page House Expertise Body study. That study listed adding presidential-nomination requirements and separating legislative and presidential election dates.

The arithmetic narrows the 2029 field. Only 8 parties sit in the House (580 seats); 7 of them, holding 470 seats (81%), back Prabowo. A 2-House-party rule caps the field at 4 tickets in theory. In practice it means 1 coalition ticket plus at most 1 PDI-P-led ticket, and only if PDI-P (110 seats) can peel away a partner. Parties outside the House (e.g. PPP, PSI, Perindo) could not nominate at all, even though the January 2025 ruling gave them that right.

It tests Indonesia’s courts. The MK said nominations may be regulated, but not by seat or vote share. Requiring House seats is arguably a seat-based test by another name. A House-government push against MK rulings repeats August 2024, when an attempt to override MK’s regional-election ruling triggered nationwide protests and was dropped within days.

It feeds a wider governance narrative. It lands alongside reported recentralisation of fiscal and education powers and a Jakarta Post editorial on public discontent (22 Sep). For foreign investors the issue is not 2029 itself but policy predictability and checks on executive power under a supermajority.

3. Market impact

No market move can be pinned on this story alone; it lands on assets already under stress, adding a governance-risk premium. Stocks fell 7% in September with IDR 7.2 trillion of foreign selling, and 10-year yields hit 7.20%.

Market	Level	Move	Read-through
Jakarta Composite Index (JCI)	6,071.14 (30 Sep close)	-0.83% d/d; -6.96% in September; about -21% vs 7,710 on 5 Mar	Fourth straight losing day; banks (BBRI, BBNI), Telkom (TLKM), Astra (ASII) led foreign selling in late September
Foreign equity flows	IDR 7.20 trillion net sell (1 to 29 Sep)	About US$400m	Governance headlines make it harder to win these flows back
10-year SBN yield	7.20% (29 Sep)	+21 bp m/m; +85 bp y/y	Higher state funding cost for Prabowo’s spending programmes; political-risk premium is part of the spread
USD/IDR	17,913 (25 Sep)	-1.3% over 30 days; 2026 range 16,675 (1 Jan) to 18,175 (record weak)	Bank Indonesia intervening; a governance shock could retest 18,175
Sovereign rating	Negative outlook since early Mar 2026	JCI fell 4.5% on the day of that decision	Rating agencies weigh institutional checks; an override of MK rulings is a direct input
Energy (Brent)	About US$100/bbl (1 Oct)	+57% y/y	Not affected by this story, but it widens Indonesia’s fuel-subsidy bill and limits fiscal room
Freight and war-risk insurance	Not affected	n/a	Domestic political story; no shipping-lane effect

4. Who is affected

The direct losers are small and non-House parties and would-be challengers; the indirect losers are investors who price Indonesia on institutional checks.

Group	Named players	Effect	Direction
Ruling coalition (KIM Plus)	Gerindra, Golkar, NasDem, PKB, PKS, PAN, Demokrat (470 of 580 seats)	Controls who can field a 2029 ticket; NasDem and Golkar on record in favour	Benefits
Opposition	PDI-P (110 seats, largest party)	Needs 1 House partner to nominate; all others are in the coalition	Hit
Non-House parties	PPP, PSI, Perindo, Hanura and new parties	Would lose the nomination right MK gave them in Jan 2025	Hit hard
Potential independent-minded candidates	Figures polling outside the coalition’s chosen ticket	Fewer parties able to carry them	Hit
Constitutional Court and KPU	MK, General Elections Commission	Likely fresh judicial review; KPU rule-making delayed	Institutional strain
Banks and index heavyweights	BRI (BBRI), BNI (BBNI), Bank Mandiri (BMRI), Telkom (TLKM), Astra (ASII)	Most exposed to foreign-flow swings on governance headlines	Negative
Long-horizon foreign investors	Nickel and battery (e.g. Vale Indonesia, Harita Nickel, IMIP tenants), data centres, power IPPs	Regulatory predictability is the key risk, not the election rule itself	Negative at the margin
State investment vehicle	Danantara (reportedly opening a Hong Kong office)	Fundraising pitch rests on governance credibility	Negative at the margin

Geographies: national, with Jakarta (House, MK) as the decision centre; protest risk is highest in Jakarta, Yogyakarta, Bandung, Surabaya and Makassar, which saw large student protests in Aug 2024.

Supply chains at risk: none directly. A repeat of August 2024-style protests would disrupt central Jakarta logistics and offices for days, not weeks.

5. Scenarios (next 2 to 8 weeks, to late Nov 2026)

The bill is unlikely to pass within 8 weeks; the window is about which drafts reach the House floor and how the street and markets react. Probabilities are our estimates.

Scenario	Trigger	Probability	Market signal	Impact
De-escalation	Gerindra or Prabowo publicly rejects the 2-party rule; draft keeps open nominations; threshold stays at or below 5%	30%	JCI recovers above 6,300; 10y yield back under 7.0%	Governance premium fades; focus returns to fiscal and energy drivers
Base case	Proposal enters House drafts in October alongside a 5% threshold; slow committee debate; civil-society criticism, small protests; no final vote before 2027	50%	JCI range 5,900 to 6,300; USD/IDR 17,800 to 18,100; foreign selling continues at a slower pace	Uncertainty lingers into 2027; MK challenge prepared for when the law passes
Escalation	House fast-tracks the bill in a few sittings; MK rulings openly sidelined; large student protests as in Aug 2024	20%	USD/IDR breaks 18,175 record; 10y yield above 7.5%; another JCI drop of 5% or more	Rating-agency commentary, central Jakarta disruption, pressure on Bank Indonesia to intervene

6. Actions to consider

Treat this as a policy-predictability risk on Indonesia exposure: hedge IDR, stress-test for a retest of the 18,175 record, and build protest contingency for central Jakarta.

Finance and treasury

Hedge 50% to 75% of next-6-month IDR payables and receivables; budget a USD/IDR stress case of 18,500.

Reprice IDR funding at a 10-year SBN of 7.2% to 7.5%; delay non-essential IDR bond issuance until after the October House sittings.

For equity holders, cut overweight in foreign-flow-sensitive banks (BBRI, BBNI, BMRI) relative to domestic-demand and commodity exporters (e.g. PTBA, Chandra Asri, which saw foreign buying).

Procurement and supply chain

Lock IDR-denominated supplier contracts now with currency-adjustment clauses triggered above 18,000.

Add 1 to 2 weeks of buffer stock for Jakarta-dependent distribution in case of multi-day protests.

Legal and government relations

Review stabilisation and change-in-law clauses in Indonesian concessions, licences and PPAs.

Map exposure to permits that could be revisited after 2029 (mining IUPs, data-centre approvals, energy PPAs).

Brief government-relations teams on each coalition party’s stated position; engage via chambers (AmCham, EuroCham, US-ASEAN Business Council) rather than directly on electoral rules.

Operations and people

Set protest triggers for staff near the House (Senayan), the MK (Medan Merdeka Barat) and the Palace: work from home, travel advisories, office closures.

7. What to watch next

The decisive signal is Gerindra: if Prabowo’s party endorses the 2-party rule, it passes; if it stays silent or opposes, the idea likely fades.

Indicator	Who / when	Current reading	Trigger and inference
Gerindra position	Sugiono, Dasco, Prabowo; October	Silent on 2-party rule; backs 5% threshold	Endorsement means escalation; rejection means de-escalation
Bill tabled and fast-track signals	House Commission II, Legislation Body (Baleg); October	Deliberations expected “sometime in October”	Bill passed in under 2 weeks or debated late at night mirrors Aug 2024 and signals escalation
Election schedule split	KIM Plus leaders, Expertise Body study	Option to separate legislative and presidential votes on the table	A split weakens MK’s simultaneity rulings and adds a second governance flashpoint
PDI-P response	Megawati, Hasto, PDI-P faction	Proposed 5.5% to 6% threshold in May; no public word on the 2-party rule	Opposition alignment with small parties raises the cost of passing it
MK and legal community	Constitutional Court, Perludem, ICW, law faculties	Experts already warning	Pre-emptive judicial review petitions show expected legal fight
Street mobilisation	BEM-SI student groups, labour unions	Not yet	Protest calls around House sittings: Aug 2024 repeat risk
Foreign flows and yields	IDX, DJPPR SBN auctions; weekly	IDR 7.2 trillion equity outflow in Sep; 10y at 7.20%	Weak SBN auction bid-to-cover or yields above 7.5% show governance risk being priced
Rupiah	Bank Indonesia; daily	About 17,900	Break of 18,175 record forces bigger intervention
Rating agencies	S&P, Moody’s, Fitch comments	Negative outlook since Mar 2026	Any reference to institutional checks moves the outlook toward a downgrade

8. Bottom line

Prabowo’s coalition (470 of 580 House seats) is weighing a rule requiring at least 2 House parties per presidential ticket, which could undo the Jan 2025 court ruling; it adds a governance premium to markets already down 7% in September, with 10-year yields at 7.20%.
