Ratchet and Repair

The companion essay, “The Return of the Single Door”, closed with four scenarios for Indonesia to 2030 and a set of assessed probabilities. This paper converts those scenarios into a monitorable instrument: explicit indicator thresholds, discrete event triggers with probability-revision rules, regime-dating criteria, quantified paths, and falsification tests.

Note: the thresholds are calibrated judgments, not econometrics. They are anchored to (a) verified August 2026 values, documented in the companion essay; (b) Indonesian stress episodes: 1998 (reserves $14.4bn, 80% depreciation), the 2013 taper tantrum (rupiah −20%, reserves $112bn→$96bn, current-account deficit 3.2% of GDP), 2018 (reserves −$14bn, BI +175bp), Covid 2020 (deficit 6.14%); and (c) statutory trip-wires (the 3% deficit law, BI’s mandate, MSCI’s stated review points). Their value is consistency: the same lines applied every quarter, so drift is measured rather than felt.

1. Scenario definitions

Semantics: Indonesia is currently in an S1 regime (the panel below confirms it). The probabilities answer: which regime prevails over the next 24 months. Section 7 extends to 2030. Probabilities are revised in a dated tracking log using the §3 deltas; floor any scenario at 2%; renormalise to 100 after each application.

2. The indicator panel

Twelve indicators, four states each: G (repair), N (drift — the S1 band), A (amber — tightening), R (red — S3-consistent). Sustained = held for a full quarter unless stated. Baseline state as of 15 Aug 2026 in the final column.

Panel reading, 15 Aug 2026: 1 G, 10 N (one at A-boundary), 1 A, 0 R → S1 operative. Consistent with the 45% prior.

Supplementary series (tracked, not scored): official-vs-corrected growth gap (>1.0pp sustained = credibility damage continuing; <0.5pp = repair); manufacturing growth minus electricity value-added growth (>3pp in a quarter = red-flag print); IDX foreign net flow (renewed outflow >$1bn/mo ×3 = S3-consistent); middle-class series (next print <46M = erosion continuing; <44M by 2028 = S3-consistent); 5-yr CDS (level to be established at next check; >200bp amber, >280bp red); parallel/NDF premium over spot (>2% = controls binding; >5% = S4 signature).

Threshold rationales, briefly: the 18,250 line is the 2026 crisis peak; holding below it means the June shock remains the floor of the range; 19,500 is ~10% beyond, the point at which the Rp17,500 budget assumption and corporate hedging break; $120bn reserves ≈ 4.7 months of imports, comfortably above the 3-month adequacy convention but the level at which 2018-style defensive tightening became unavoidable; −3% CAD reproduces the 2013 vulnerability; 3.0% deficit is statute; Rp300T of BI purchases ≈ 45% of the 2027 financing need, the point where “secondary-market operations” stops being a defensible description.

3. Event triggers

Applied once per event, at resolution, to the four probabilities (percentage points); then renormalise. Gateway events (†) additionally arm the S4 alert (§6).

Two consecutive official sub-4.5% prints score positive for S1/S2 deliberately: a state that publishes a bad number has chosen honesty over the series, which is repair of the instrument even as it marks a weaker economy. The panel (§2) captures the economic deterioration separately.

4. Regime-dating rules

Applied at each quarterly review; the call is recorded in the tracking log.

• S3 regime declared: ≥3 panel indicators R sustained a full quarter, or 2 R plus any 2 gateway events within 12 months.
• S2 regime declared: ≥6 G, zero R, and at least two structural repair events from §3 (Constitutional Court strike, threshold restoration, DSI dilution, BPS audit, clean MSCI outcome) inside 12 months. Price recovery alone never dates S2: July 2026 proved a 10% rally coexists with an intact ratchet.
• S4 alert (not yet regime): any 2 gateway (†) events within 90 days, or any 1 gateway plus 2 R states → move to weekly monitoring, §6 checklist.
• S4 regime: the currency criterion: >7% depreciation within 30 days with intervention visibly failing, or any deposit/convertibility restriction.
• Default: S1. Ambiguity resolves to the incumbent regime; regimes change on evidence, not vibration.

5. Quantified scenario paths

Indicative annual paths, year-end values. “Underlying growth” = the LPEM-method corrected estimate (the arithmetic behind the correction is set out in the companion essay); the official series is assumed to keep printing above it in S1/S3 (the gap is itself an indicator). Middle class = BPS/Mandiri definition.

S1 — Managed drift (45%)

Signature: 3–4% annual depreciation as a managed tax; the deficit kisses the cap in the 2029 election year; FDI into resources stays strong throughout; the official-underlying gap persists near 0.7–0.9pp. Nothing breaks. Everything discounts.

S2 — Credibility repair (20%)

Signature: the official-underlying gap closes below 0.5pp (the honesty dividend); foreign SBN share back above 15% by 2028; IHSG regains its January-2026 peak in 2029, roughly three and a half years after losing it. Requires the §4 S2 dating conditions — two structural repairs, not a rally.

S3 — The ratchet (25%)

Signature: the 22,000–25,000 rupiah calls that circulated as alarmism in May 2026 become the 2029–30 track; MSCI frontier lands 2027; the cap is amended rather than breached (“temporarily”, Covid precedent cited); under-invoicing returns through DSI; Kopdes credit sours on Himbara books from 2028; the election is fought on distribution and won by the machine. Note what S3 is not: production does not collapse, exports continue, FDI into nickel persists — Argentina 2011–15, not Venezuela.

S4 — Rupture (10%)

Event path, not an annual table — see §6.

6. S4 anatomy

Gateway triggers (†, from §3): non-resident capital controls; Himbara recap/bailout; Himbara deposit flight >10%/quarter; unrest with deaths or emergency powers; succession crisis; election-postponement talk; plus the §3 external pair (Brent >$120 quarter) when combined with any other gateway.

Windows of maximum vulnerability:

1. Q1–Q2 2027. DSI sole-channel go-live meets the MSCI aftermath meets the first test of the 6%-growth revenue arithmetic: three stress vectors on one calendar. If the November review opened a consultation and DSI jams covered exports and H1 revenue misses, the S4 alert will likely arm here.

2. H2 2028 – 2029. Kopdes and MBG (free-meals) credit seasoning on Himbara balance sheets coincides with election-year spending and any global downcycle. The four state banks are the single point of failure: they simultaneously hold the trapped export dollars, the cooperative loans, the buyback losses and the SBN book.

Sequence sketch (the plausible order, not a forecast): reserve drain accelerates past −$5bn/month → BI hikes into weakness, real rate still negative → a Himbara stress rumour meets the deposit base → deposit migration to foreign and private banks → authorities respond with the instrument the architecture has prepared, restriction rather than rate: FX withdrawal limits or forced conversion → the restriction converts a bank problem into a currency panic (the 1997 liquidation lesson, re-learned) → rupiah gaps through 21,000; the question of external support returns to a political system for which the IMF is the national humiliation myth. Assessed outcomes from there: orthodox stabilisation within 2–3 years (the 1998–2003 shape, ~40%), an Argentine doubling-down (~35%), forced early political transition (~25%).

Quantified S4 signature: rupiah −25 to −40% inside two quarters (21,000 → 24,000+); reserves −$15–25bn over two quarters, through $110bn; inflation >10% within a year; IHSG <4,500; at least one negative official growth quarter, the first since 2020; spreads: CDS >280bp, 10-yr SBN >9%.

7. Transition dynamics

Assessed annual transition likelihoods between regimes (%, rows sum to 100). These are coherence devices: they force today’s probabilities to imply cumulative risk honestly, nothing more.

Implications worth stating plainly:

• P(an S3 regime at some point before end-2030): ~45–50%. The ratchet does not need to be the base case to be the modal visited state.
• P(an S4 episode before end-2030): ~18–22% cumulative, roughly one in five. Fat for a country with $145bn of reserves; thin for one whose policy risk concentrates in four bank balance sheets.
• S2 is sticky if reached (70% persistence): repair compounds, because each repaired institution lowers the risk premium on the rest. The problem is reaching it: from S1 the annual chance is 15%, and it requires the government to move before pressure peaks, which is the one thing the record says it does not do.
• The S3→S2 cell (3%) is the Argentine lesson quantified: once the ratchet regime is established, its constituencies defend it; exits run through crisis (S4) or exhaustion (S1), almost never through voluntary reform.

8. Falsification

The central thesis of the companion essay — that the single-door reversion is structural, not cyclical — is falsified, and this framework should be rebuilt around S2 as base case (>50%), if three or more of the following occur by end-2027:

1. PP 24/2026 repealed, or DSI formally reduced to a reporting/marketing agency with exporters’ direct sales restored;
2. Art. 50A struck down and Danantara brought under ordinary state audit (BPK);
3. FX documentation threshold restored to ≥$50k/month;
4. DHE retention cut back to ≤30%/3 months as the general rule (not by bilateral exemption);
5. Kopdes bansos (social-assistance) exclusivity reversed — distribution returned to agencies/direct transfer;
6. BI mandate re-narrowed to price/financial stability (re-amendment of the P2SK financial-sector law).

Fewer than three by end-2027, the thesis stands. Zero (the current trajectory), and S3’s weight should be reviewed upward at the 2027 annual revision regardless of market prices, because prices follow the doors with a lag.

Symmetrically, the framework itself, not just the thesis, needs rebuilding if the official-underlying growth gap closes while controls persist (statism that works better than assessed here), or if a leadership change re-scrambles every assumption before the 2029 window.

9. Operating protocol

• Quarterly full review (with each BPS release): score all 12 panel indicators, record the G/N/A/R count, apply any §3 event deltas, restate probabilities, date the regime per §4. Log the result.
• Monthly light check: indicators 1, 2, 9, 10 plus any §3 events. One log line suffices if nothing moved.
• On S4 alert (§4): weekly cadence; add daily rupiah/JISDOR spread, Himbara deposit reporting, and BI announcement monitoring.
• Data to establish at next check: 5-yr CDS level; exact 10-yr SBN yield; latest monthly inflation print; IDX foreign flow YTD update.
• Annual revision (each August): re-anchor thresholds to the new baseline, re-assess the transition matrix, and re-run §8.

Prepared 17 August 2026. Baseline values as verified at that date; the evidentiary base, with sources, is set out in the companion essay, “The Return of the Single Door”. Single-source figures (resident outflows, cumulative foreign withdrawal) are excluded from the panel deliberately — no indicator in §2 depends on an unverifiable series.
