The Populist Paradox: Why Institutional Erosion Outlasts Economic Promises

In this episode of Not Another Politics Podcast, the hosts examine Christoph Trebesch’s research on the global rise of populism. The findings show that populism is not just a rhetorical style but a systemic shift that consistently wears down democratic institutions and leads to long-term economic stagnation. The hidden consequence is the serial nature of populist governance: once a country enters this cycle, it rarely returns to its previous political balance. This analysis matters for those watching global governance because the primary risk of populism is not a sudden economic crash, but the slow, durable degradation of the checks and balances that support market stability. Understanding this helps in forecasting political instability and institutional decay over 10 to 20 year horizons.

The Hidden Cost of Us vs. Them Governance

The most significant insight from Trebesch’s research is that populism functions as a thin ideology built on an us versus them rhetorical strategy. While public attention often focuses on the economic promises made during campaigns, the data shows that these leaders rarely deliver on them. Instead, the downstream effect is a consistent dismantling of judicial independence, media freedom, and electoral integrity.

This creates a feedback loop: populists are often elected during periods of economic distress, but their subsequent actions, specifically the weakening of institutional constraints, actually worsen the country’s long-term economic decline.

"The populist then pretends to be on the side of these true people fighting against the corrupt elite that has captured a government. So this is, and this rhetoric of us versus them is really what is at the core of both the electoral campaign and the ruling strategy of populist."

-- Christoph Trebesch

The 10-Year Stagnation Trap

Conventional wisdom often frames the economic impact of populism as a sugar rush, an initial boom followed by a sharp inflationary crisis. However, Trebesch’s data reveals something more persistent: long-term stagnation. Ten years after a populist leader takes office, GDP per capita is typically 10% lower than it would have been under a non-populist government.

The system responds to this by creating a new class of politically connected entrepreneurs who thrive not through market competition, but through state-sanctioned access to gains. This shift replaces a functional market with a form of institutionalized cronyism that persists long after the populist leader leaves, creating a bad equilibrium that is difficult to escape.

Why the System Struggles to Correct

The conversation highlights a troubling dynamic: once a country enters a populist cycle, it rarely cures itself. The hosts note that even in countries with recent histories of dictatorship, where one might expect a heightened sensitivity to institutional erosion, populist parties are making sudden, significant gains.

This suggests that the establishment, which previously maintained the peaceful exchange of power, is losing its effectiveness. As populists push boundaries and the establishment reacts with aggressive legal or bureaucratic countermeasures, both sides become trapped in a cycle of mutual recrimination. This environment makes it difficult to return to a normal political order, as each side becomes convinced that losing power means facing existential threats, such as imprisonment.

"Once you had a populist in office at the high at the presidential or premier level, the likelihood you see another populist following increases. What I came to realize... is that we live in a populist era and this is likely to stick with us."

Key Action Items

• Monitor Institutional Metrics: Do not judge the health of a political system by short-term GDP growth or stock market performance. Watch judicial independence scores and media freedom indices. These are leading indicators of long-term economic erosion (12 to 18 month horizon).
• Identify Serial Risk: Recognize that populism is not a one-off event. If a country has elected a populist leader, the probability of future populist governance increases significantly. Adjust long-term investment risk profiles accordingly (5 to 10 year horizon).
• Look Beyond Rhetoric: Distinguish between anti-establishment rhetoric and institutional dismantling. A leader may criticize the status quo, but the danger lies in the specific actions taken to bypass checks and balances.
• Prepare for Bad Equilibrium: In regions showing signs of populist cycles, assume that traditional market-based competitive advantages will be replaced by political-access-based advantages. Re-evaluate operational reliance on government contracts or state-aligned entities (18 to 24 month horizon).
• Assess the Establishment Response: Observe how the existing political class responds to populist entrants. If the response is purely reactive or divisive, it may accelerate the breakdown of the rule of law, creating a more volatile and less predictable business environment (immediate to 12-month horizon).
