Every national leader, scored across up to eight dimensions of tenure contribution — from governance and economy to politics and crisis response. Compare current form against the legacy they'll leave behind.
Lee Jae Myung, President of South Korea, has no composite Leadership score yet — too few dimensions have sourced data to compute one. Their standout dimension is Institutional Integrity (92/100). The pressure to watch: Weak Stability Trend — Stability Trend of 39 indicates that the recent direction is a material pressure even when the broader stability level remains stronger.
The data & sources
Lee Jae Myung carries no composite rating: too few dimensions have sourced data, so it renders as "No data" rather than a filled-in guess. Diplomatic Conduct 80/100 (medium confidence) — performance-under-test blend from directed GDELT events + UCDP. Governing-stability conditions score 78/100, renormalised over WGI, V-Dem and UCDP.
The risk read
For country-risk purposes, Lee Jae Myung's tenure reads as broadly stable: governing-stability conditions score 78/100. Crisis exposure 10/100 (Minimal exposure); response untested. For the full opportunity, market-pulse and resilience read, see South Korea's nation page.
The strategic read
Governing conditions: stability 78/100. Live pressures: weak stability trend.
Analyst OutlookAI · not a sourced score
claude-fable-5 · 2026-08-24
Cited, adversarially-verified forward analysis — every claim is sourced and survived a red-team. An LLM intelligence brief, not a sourced score, and never blended into this leader's ratings.
Trump halved the joint drills and Kim slammed the door, yet the number killing Lee Jae-myung is 9.56% — Seoul housing inflation — while the alliance 'crisis' he is blamed for is quietly delivering the wartime-command transfer Korean progressives could never negotiate on their own terms.
The Consensus
The honeymoon is over: Lee's pragmatic pivot won a year of goodwill and a 3%-plus, chip-fuelled economy, but approval has fallen from 64% to the low 40s in four months on housing, a supermajority's judicial overreach and a Trump who cut the joint drills and told Seoul it isn't earning its US troops; conservatives read one-party drift, foreign investors have sold Korean assets for six straight months.
The October 2026 Security Consultative Meeting produces a dated target for wartime OPCON transfer — a year no later than 2030 — rather than another 'conditions-based' roadmap.

Wrong if no SCM is held by 2026-12-31, or if its joint communiqué names no target year for OPCON transfer, or names a year later than 2030. by 2026-12-31

Strongest counter — The SCM has slipped before, Trump just used readiness as a bargaining chip over Iran, and a US that halves drills on a whim can also refuse to bind itself to a date — leaving Seoul with a 'roadmap' and no year. Survives because both sides now want the same thing for different reasons: Seoul for autonomy, Washington to offload; the USFK commander has already published the conditions timeline and the 2026 strategy prices USFK adjustments from 2030, so the date is the easy concession to make.

ⓘLeadership Rating measures change under the leader relative to global trends — a score near 60 means performance broadly matched the benchmark trajectory. It is a weighted average of up to eight dimensions, renormalised over the ones with sourced data (the coverage note beside the score says how many), and requires all four core dimensions — Governance, Economy, Politics and Institutional Integrity — to be sourced. Five use live World Bank indicators; the rest are derived from sourced signals (WIPO/Oxford/UNESCO, GDELT, World Bank + UCDP, survey data) where coverage exists. Diplomacy is a GDELT-derived engagement proxy, and anything unsourced shows as no data. Political position is V-Dem V-Party expert coding. Full weights on the Methodology page.

Test Severity (active conflict + conflictual share + sanctions received) amplifies the blend so conduct under fire moves the score more. Full model on the Methodology page.
ⓘCrisis Exposure measures how severely a leader was tested — a peak-biased aggregate of per-year shock severity (conflict intensity, economic contraction and political-stability decline vs. recent normal) over the mandate. It is context, not a verdict: high exposure is neither good nor bad on its own. Crisis Response measures how the country fared during its genuine crisis years relative to comparable crisis episodes worldwide — country-years hit with the same shock severity. Higher = less national damage than peers at that severity. Leaders who never faced a major shock are marked Untested rather than rewarded. Per country-year, real WB/UCDP/WGI shocks are winsorised and percentile-ranked into a ShockSeverity; Exposure is the peak-biased mandate aggregate. Crisis years (severity ≥ 60) score Response = 100 − damage percentile among comparable-severity crises worldwide, then severity-weighted over the mandate. Untested = no major shock (never rewarded). Absent components are reweighted, never filled.

A score near 60 means performance broadly matched the benchmark trajectory; above = improved the country's standing, below = declined. Governance / Economy / Politics / Institutional Integrity from World Bank WGI, WDI and V-Dem trajectories; Vision from the country's innovation rank (WIPO patents + UNESCO tertiary), former leaders only (patents lag ~3 years); Crisis Response (World Bank + UCDP + WGI, an absolute response-quality scale) and Communication (GDELT) from tenure signals; Diplomacy (Diplomatic Conduct) is active-only. A tenure under six months, or an indicator whose series hasn't reached the term, shows as no data. Full model on the Methodology page.

Source: World Bank WGI + V-Dem + derived·Method: Stewardship·✓ ReconstructableⓘMeasures whether strong institutions inherited at the start of the tenure were preserved, improved or eroded. It does not reward the leader for inheriting a strong country. A metric qualifies only when the inherited baseline was at least 75 on its normalized scale; the score is the world-net change over the tenure on the single public scale (60 = preserved relative to global movement). Requires two or more eligible sourced groups, the six-month tenure floor and a post-tenure-start observation — otherwise No data, never a zero. Weights mirror the current-form groups (gov 0.17 · pol 0.15 · int 0.08 · vis 0.09), renormalized over what is eligible and sourced.

Stability Trend of 39 indicates that the recent direction is a material pressure even when the broader stability level remains stronger.
Source: Derived·Method: Rule-based·✓ ReconstructableⓘFlags challenges when a sourced dimension falls below the published benchmark band: any leadership dimension < 58 (severe < 48), Stability < 50, Crisis Exposure > 60, or regime continuity/legitimacy < 40 — plus an adverse Stability Trend, adverse External Conditions, or Severely Constrained / Extreme domestic context. Economy derives from World Bank indicators; Institutional Integrity from V-Dem's executive-corruption index (World Bank Control of Corruption as fallback); Communication from GDELT media reach, tone and resilience; Crisis Exposure and continuity from the stability blend. A low Communication signal can mean thin coverage OR wide-but-hostile coverage — the flag distinguishes the two.
