Episode: What happens to central banks under pressure?

Date: September 6, 2025

Brief Overview

This episode delves into the critical importance of central bank independence and the dangers posed when political forces attempt to undermine it. Through the perspectives of three renowned "central bank watchers"—Carolina Garriga, Lev Menand, and Carola Binder—the hosts unpack what defines central bank independence, how it can erode, and why regaining trust is so difficult once lost. The discussion draws on historical and recent global examples, examining both statutory rules (de jure) and practical implementation (de facto), and focuses particularly on the current situation in the United States.

Key Discussion Points & Insights

1. The Watchers: Who Watches Central Banks and Why?

• Carolina Garriga is introduced as a "watcher" of central banks, tasked with monitoring challenges to their independence worldwide.
• She traces her origin to Argentina, a "canary in the coal mine" for politically pressured banking, recalling family accounts of inflation-driven shortages.
• Example cited: Turkey, where presidential influence led to massive inflation and loss of monetary credibility (01:18–02:18).

"Turkey is another poster child of what not to do with monetary authorities."
— Carolina Garriga, 01:44

2. The Harm: What Happens When Independence Fades?

• Loss of independence correlates with higher volatility, inflation, and long-term economic instability (02:38–03:16).
• Unique global ramifications when the U.S. dollar’s credibility is threatened, due to its use as a reserve currency (03:01–03:16).

"None of those are good things. And none of those things are easy to fix once they're unleashed."
— Carolina Garriga, 03:16

3. Where Central Banks Came From and Why Independence Matters

• The modern central bank model grew from British and American "missionary work" in the 20th century (06:02–06:58).
• The last 50 years have seen an increasing emphasis on keeping central banks separate from political cycles (07:02–07:18).
• Political meddling leads to short-term gains but long-term pain (07:18–08:55).

"The harm is that monetary policy decisions may be made by political interests that can cause damage in the long term."
— Carolina Garriga, 07:22

4. Measuring Independence: A Search for Better Metrics

• Lev Menand and colleagues revisit how independence is defined, challenging previous indices that overlooked loopholes, e.g., a long governor term is meaningless if the executive can dismiss at will (10:19–13:04).
• Their research involves granular, subjective coding of legal features and surveying actual central bank officials (13:24–16:15).

"It's not worth much to have an eight year term if you can be removed at will."
— Lev Menand, 12:41

• Fundamental divide highlighted: laws on the books (de jure) vs. actual practice (de facto) (16:15–17:47).

"You could have a state of the art central banking statute ... but there's no rule of law ... then there's no de facto independence, even if you're a 10 out of 10 on de jure independence."
— Lev Menand, 16:51

5. Beyond Rules: Watching What Central Banks Actually Do

• Carola Binder studies actual central bank behavior in response to political pressure, drawing on nuanced, narrative-based news reports (19:41–21:41).
• Finds that about 10% of central banks are pressured annually, and nearly 40% between 2010–2018 (22:10–22:53).
• Pressure is almost always directed toward looser monetary policy (cutting rates), as seen in Turkey and the U.S. (22:53–23:22).
• Central banks succumbing to pressure consistently see spikes in inflation (23:22–23:55).

"If a country goes from there not being any reports ... then suddenly one quarter they start facing [pressure]. What happens to inflation afterwards?"
— Carola Binder, 22:21

6. Why Is Independence So Hard to Win Back?

• Once lost, it may take decades and painful reforms to rebuild credibility—see the U.S. after the Nixon era (25:00–26:03).

"Building institutions takes decades, but destroying institutions take very little time."
— Carolina Garriga, 25:13

• Increasing political consolidation (e.g., transition to presidential systems) exacerbates pressure (24:54).

7. Current U.S. Context

• Discussion of Trump’s public pressure campaigns on the Federal Reserve, attempts to remove board members, and the unprecedented legal battles currently shaping U.S. central banking (26:18–27:16).

"We have the United States scored as having independence ... But if courts ... determine that for cause doesn’t really mean anything, then we maybe don’t have this scored right."
— Lev Menand, 26:48

Memorable Quotes & Moments

• On Central Bank Pressures and Global Ripples:
  "The dollar in itself is a matter of concern for most countries in the world. If there is loss of credibility ... this will have a rippling effect."
  — Carolina Garriga, 09:35

• On Research Methodologies:
  "Somebody has to read the whole statute and go through and decide, is this a one or zero on this dimension?"
  — Lev Menand, 13:56

• On Regaining Lost Independence:
  "The trust in the system or the long term trust in the institutions is hurt. And that takes a long time to rebuild."
  — Carolina Garriga, 25:42
