What was done, how, why, by whom — with sentiment and market impact. A step-by-step walkthrough of 8 coordinated actions by Bank Indonesia, the Government, and OJK.
The core
What happened
Between early May and 4 June 2026 the rupiah fell to a record low (breaching Rp18,000 for the first time on 4 June) and the IHSG slid to its lowest since 2021. Authorities ran a coordinated but contested defense across three institutions — Bank Indonesia, the Ministry of Finance, and OJK with BEI.
Why it failed
Public sentiment was predominantly negative and distrustful. Drone Emprit measured 72.2% negative sentiment (14–20 May). Reassurance messaging from the President and Finance Minister backfired and was widely mocked. The rate hike split opinion, the DHE rule drew a formal Chinese-investor protest, and the market impact of all measures was, at best, temporary: the rupiah hit its record low two weeks after the rate hike.
Market outcome
What happened after a month of response. These are the measurable outcomes investors, exporters, and households saw as the policy mix rolled out.

The full story
Each action is broken into six questions: What was done, how, why, by whom, what sentiment was received, and what impact followed. Click a card to open the detail.
What
Bank Indonesia raised the yields on its rupiah securities (SRBI) to 6.21%, 6.31% and 6.45% for the 6-, 9- and 12-month tenors.
How
Through regular SRBI auctions — a "pro-market" monetary-operation instrument designed to set attractive returns relative to US Treasuries.
Why
To widen the yield spread over US Treasuries and lure foreign portfolio money back into rupiah assets. BI later reported Q2 portfolio net inflows of ~US$5.5 billion up to 18 May, attributed mainly to SRBI and SBN inflows.
By Whom
Bank Indonesia (monetary operations).
Sentiment received
Mostly technocratic / neutral in mainstream coverage; among retail investors, high yields on safe instruments reinforced the "why hold stocks?" mood on Stockbit.
Impact
Helped attract some inflows on paper, but did not stop the rupiah's slide; the currency kept weakening through late May.
Division of labor
Three institutions, three different roles. What BI brings to the table differs from what the Government or OJK brings — and so does the public reception each one receives.
Role
Monetary authority
Tools used
BI-Rate +50 bps to 5.25%; SRBI yield hikes; triple intervention (spot/DNDF/SBN) + offshore NDF; tighter FX thresholds.
Public faces
Perry Warjiyo (Governor), Destry Damayanti (Sr. Deputy)
Reception
Mixed; #BankIndonesiaTanggungJawab trended
Effect
Brief reprieve, no lasting reversal
Role
Fiscal authority & policy
Tools used
PP 21/2026 (DHE SDA — 100% repatriation, 12-month hold, 50% conversion cap, Himbara accounts); one-door export via DSI/Danantara; public reassurance messaging.
Public faces
Prabowo Subianto (President), Purbaya Yudhi Sadewa (FM), Airlangga Hartarto (Coord. Min.)
Reception
Strongly negative; messaging mocked
Effect
Foreign-investor backlash; credibility gap
Role
Capital-markets regulator
Tools used
Buyback without RUPS, delayed short-selling, adjusted trading-halt and auto-rejection parameters (extended to Sep 2026).
Public faces
OJK Capital Markets supervision; BEI/SRO
Reception
Skeptical; conspiracy narratives on retail
Effect
Flat market response; IHSG kept falling
How the public received it
Social-media sentiment
72.2% Negative
Drone Emprit · multi-platform social media · 14–20 May 2026
Four dominant themes explain the negative reaction. The sharpest is not the technical policy — it is the communication that was perceived as dismissive.
#BankIndonesiaTanggungJawab trended alongside calls for BI Governor Perry Warjiyo to resign. Frustration shifted from economics to political accountability.
KISI analyst Muhammad Wafi flagged three concerns: DSI/Danantara taking over commodity exports, the Himbara rate-cut instruction just before BI tightened, and the President's personal fiscal messaging — read together as policy centralization.
The verdict
The response was orthodox and coordinated (rate hike + intervention + export-retention + market backstops), but its credibility was undercut by political messaging, and its effect was at most a temporary cushion. The decisive sentiment failure was communication, not the technical toolkit.
What the reader should know
One internally inconsistent source excluded
A blog (esy.almaata.ac.id) claimed BI held the rate at 4.75% — contradicting the confirmed 20 May hike to 5.25% reported by BI itself and every major outlet. Its specific claims are not used.
OJK package date uncertainty
The capital-market relaxation is confirmed as a 2026 measure, but the exact announcement date in the source is ambiguous. Buyback-without-RUPS is a recurring tool (2013/2015/2020/2025) — treat the "flat market response" as the established pattern rather than a precise 2026 reading.
Lower-quality outlets flagged
Some details (KISI's three concerns, certain intraday levels, China-protest specifics) appear on weaker or likely-AI-assisted sites (babelinsight.id, asatunews.co.id, pojokpapua.id, fxstreet-id.com). Where possible they are attributed to a named analyst/institution.
Sentiment quantification is thin
The only robust number is Drone Emprit's 72.2% negative (14–20 May). There is no published volume/engagement figure for the 4 June "Udah 18K" trend — confirmed as #1 trending but without counts.
Coordination-meeting date
One documented government–BI synchronization meeting (Prasetyo Hadi + Purbaya + Perry) is dated to January 2026 in its source; it illustrates the standing coordination mechanism rather than a within-period event.
Conflicting headline figures
Different cut-off dates/methods, not contradictions: IHSG YTD decline ~29% (CNBC Indonesia) vs ~34% (Bloomberg/Trading Economics); 4 June record low cited ~Rp18,003–18,047.
Verifiable
Every claim maps to a numbered source. Lower-quality sources are flagged openly — their specific figures should be corroborated against reputable outlets.
Scope: Indonesia. Social-media sentiment skews toward more vocal and negative participants and is not a representative population survey. Policy mechanics are sourced to official releases (Bank Indonesia, Ministry of Finance via PP 21/2026, OJK) and reputable press; market figures are supporting context and may be revised by primary sources. Forward-looking official projections (H2 strengthening, DHE effect by end-June) are forecasts, not realized outcomes within this window.
