ECB's TPI stopped eurozone yield divergence without buying a single bond
In July 2022 the ECB announced a conditional, unlimited bond-purchase backstop — the TPI — and peripheral spreads calmed without it ever being used.
European Central Bank
The solution
As the ECB began raising rates in 2022, borrowing costs rose faster in the eurozone periphery than in core countries, threatening to break the single transmission of monetary policy. Italy, with heavy debt and a government crisis, was the focus of market fear.
On July 21, 2022 the Governing Council approved the Transmission Protection Instrument: secondary-market purchases of public-sector securities with one-to-ten-year maturities, 'not restricted ex ante' in scale, activated when spreads widen for reasons not justified by country fundamentals.
Eligibility depends on a cumulative list of criteria — compliance with EU fiscal rules, no severe imbalances, sustainable policies as judged by the Commission, ESM and IMF. The PEPP's reinvestments remain the first line of defense, with the older OMT program as a further backstop.
Why it worked
- Unlimited size makes the backstop credible against speculative attacks.
- Conditionality keeps it from underwriting fiscal indiscipline.
- Focused maturities and secondary-market purchases limit footprint.
- It works by changing expectations, so it can cost nothing.
What can be applied
A conditional, credible backstop can calm a market at zero cost — the announcement itself is the policy, and the conditions stop it becoming a subsidy for bad policy.
Aftermath
Spreads narrowed sharply after the announcement, and the TPI has never been activated. It sits alongside PEPP and OMT as a third layer of anti-fragmentation defense in the ECB's toolkit.
