Episode recorded on 19 June 2026 at the PSE-CEPR Policy Forum in Paris.Twice before, the world's savings and debts have piled up in the wrong places, and twice the imbalance broke something. The first time it took the Plaza Accord to fix it. The second time it took a global financial crisis.Now we are in a third wave. Gita Gopinath (Harvard, former IMF Chief Economist and First Deputy Managing Director) and Philip Lane (European Central Bank, CEPR) join Tim Phillips to ask what is different this time.Household and bank balance sheets are stronger than before 2008. But the fragility has moved to governments carrying much higher debt, and to non-bank financial institutions whose exposures and links to banks are only partly visible. Foreign investors hold US$40.7 trillion of US equities, 44% of world GDP outside the US, much of it riding on the AI boom.Lane's overriding principle: central banks can calm bond markets under stress, but they must be just as clear about what they will not do if debt is unsustainable.The research behind this episode:Bai, Chong-En, Gita Gopinath, Hélène Rey, and Axel Weber. 2026. <a href="https://www.g7.utoronto.ca/finance/G7-economists-memo-on-global-imbalances.pdf">"G7 Economists Memo on Global Imbalances."</a> Prepared for the French Presidency of the G7, 28 March.The panel also draws on the fourth CEPR/Bruegel Paris Report, <a href="https://cepr.org/publications/books-and-reports/paris-report-4-new-global-imbalances">Paris Report 4: The New Global Imbalances</a>, edited by Hélène Rey, Beatrice Weder di Mauro and Jeromin Zettelmeyer (CEPR Press and Bruegel, 2026), free to download at <a href="http://cepr.org">cepr.org</a>.Gopinath made the keynote presentation “The Third Wave: Addressing Global Imbalances” on 19 June at PSE.To cite this episode:Phillips, Tim, Gita Gopinath, and Philip Lane. 2026.

Gopinath frames today's imbalances as the third episode since the 1970s in which national savings and investment have pulled badly out of line, a framing she titled "The Third Wave" in her Atlanta Fed presentation. The first, in the early 1980s, produced the 1985 Plaza Accord, when the US and its G5 partners agreed to talk the dollar down after years of a strong currency and a widening trade deficit. The second built through the 2000s and unwound in the 2008 global financial crisis. In both, the US was the deficit country; the surplus moved from Japan to China.Foreign holdings of US equities. Gross foreign holdings of US equities stood at US$40.7 trillion, 44% of world GDP excluding the US (Gopinath 2026, citing US Treasury data). Gopinath's slides show 54% of gross foreign inflows into US government debt since 2007 and estimate that 61% of the deterioration in the US net international investment position since the global financial crisis has been driven by valuation effects rather than trade deficits.Non-bank financial institutions (NBFIs). Hedge funds, private credit funds, insurers and other institutions outside the regulated banking system now intermediate a large and growing share of global finance. Gopinath's slides show leveraged intermediation migrating from households and banks before the 2008 crisis toward government and non-bank financial institutions today, echoing the concerns set out in the G7 memo and the CEPR Paris Report.The 2020 "dash for cash." In March 2020, US Treasury yields rose sharply even as investors would normally be expected to flee to safety, a sign that market functioning, not just prices, can break down under stress. Gopinath cites the episode as evidence that hedge funds, now bigger players in Treasury market-making, can amplify rather than absorb shocks.ECB crisis tools: PEPP, OMT and TPI. Lane describes three instruments built since 2012 to separate monetary policy from market functioning: the Outright Monetary Transactions programme (2012), designed to backstop governments already in an ESM assistance programme; the Pandemic Emergency Purchase Programme (2020), the ECB's flexible, country-varying response to Covid-19; and the Transmission Protection Instrument (2022), intended to calm unwarranted bond market panic without financing unsustainable debt.US federal debt and the fiscal deficit. Gopinath's slides put federal debt at 108% of GDP in 2025, up from 41% in 2007 and 39% in 2000 (source: Federal Reserve, FRED). In conversation she cites the US fiscal deficit at close to 7% of GDP, at a point in the cycle when the economy is strong. Note this is federal debt specifically; the G7 memo cites a broader measure, US general government debt, at around 120% of GDP, projected to reach around 140% by 2031. The two figures are not directly comparable and should not be conflated in the notes or on air.More VoxTalks Economics episodesThis episode sits alongside three earlier VoxTalks Economics conversations built around the CEPR/Bruegel Paris Report 4, The New Global Imbalances.<a href="https://cepr.org/multimedia/global-imbalances-redux">Global Imbalances Redux</a>, in which Maurice Obstfeld sets out the history of the three waves of imbalances and what today's policymakers can learn from how the first two were resolved.<a href="https://cepr.org/multimedia/rebalancing-chinese-economy">Rebalancing the Chinese Economy</a>, in which Yiping Huang explains why decades of investment-led growth suppressed Chinese household consumption, and what it would take to reverse that.<a href="https://cepr.org/multimedia/stablecoins-and-global-imbalances">Stablecoins and Global Imbalances</a>, in which Gilles Moec examines how dollar-backed stablecoins help fund the US deficit, and the regulatory gaps that leaves behind.Related reading on VoxEU<a href="https://cepr.org/voxeu/columns/why-global-imbalances-matter-again-and-what-do-about-them">Why global imbalances matter again, and what to do about them</a>, a VoxEU column drawn from Chapter 1 of Paris Report 4, setting out why imbalances have widened since 2018 and the risks of a disorderly unwind.<a href="https://cepr.org/voxeu/columns/industrial-policy-tariffs-and-return-global-imbalances">Industrial policy, tariffs, and the return of global imbalances</a>, which finds that tariffs are a weak tool for correcting current account imbalances and that industrial policy's effects run mainly through its impact on domestic saving and consumption.</div>
