Raghuram Rajan on the Impact of the Ratcheting Effect of The Fed's QE Program

Episode Summary

Executive Summary: David Beckworth and Raghu Rajan discuss Rajan’s career, his warnings about hidden financial risk before the global financial crisis, India’s 2013 currency/inflation crisis and successful inflation-targeting response, and his recent research arguing that QE changes bank liability structures, increases liquidity dependence, and makes shrinking central bank balance sheets difficult. The episode closes on policy limits, moral hazard, and the Fed’s growing footprint in finance.

Main Topics: Raghu Rajan’s policy career and intellectual arc (Priority: 4/5): Rajan reflects on his roles at the IMF, RBI, BIS, and Group of 30, emphasizing the differences between academic influence and policymaking constraints. Early warnings about financial risk and the 2005 Jackson Hole speech (Priority: 5/5): He explains why he warned that tail risk had migrated onto bank and AIG-like balance sheets and why that message was controversial before the 2008 crisis. India’s 2013 fragility and RBI stabilization strategy (Priority: 5/5): Rajan recounts how fiscal weakness, inflation, and the taper tantrum hit India, and how he used inflation targeting and reforms to restore confidence. India’s growth model and the role of services (Priority: 3/5): He argues India cannot rely mainly on manufacturing-led export growth and should instead build a services-led model supported by human capital, privacy, and institutional reform. QE, bank balance sheets, and liquidity dependence (Priority: 5/5): Rajan summarizes papers with Viral Acharya showing QE can expand reserves while inducing banks to issue runnable liabilities and credit lines, increasing systemic liquidity risk. Why shrinking central bank balance sheets is hard (Priority: 5/5): The discussion ties liquidity dependence to repo stress, the Fed’s return to balance-sheet expansion, and the notion that QT becomes difficult once markets depend on central bank backstops. Policy limits, moral hazard, and the Fed’s future role (Priority: 5/5): They debate whether central banks can safely maintain large balance sheets, how to price liquidity support, and whether current Fed operations increasingly resemble government financing.

Key Arguments: The IMF’s problem in the mid-2000s was not too many borrowers but too few, which raised concerns about its income model. The pre-crisis financial system looked stable only because tail risk was being absorbed by banks and institutions like AIG, not eliminated. Warning about risks in good times is essential because crises are often seeded during periods of calm, buoyant markets, and easy credit. India’s 2013 crisis showed that exchange rates, oil imports, inflation, and fiscal weakness can interact into a destabilizing loop. Credible inflation targeting can stabilize expectations and the exchange rate even in an emerging market if paired with reforms and limited but clear rate hikes. Central bank reserves do not necessarily translate into more productive credit; banks may instead increase demand deposits, reduce time deposits, and create more liquidity claims. QE can inadvertently increase systemic liquidity risk by encouraging more runnable funding and credit-line promises backed by reserves. Shrinking a central bank balance sheet is difficult because markets and banks become dependent on the liquidity backstop once it has been repeatedly supplied. Current large-scale Fed operations look more like ongoing financing of government debt and market plumbing than temporary crisis support. Central banks face a moral-hazard problem: providing rescue liquidity prevents collapse but also encourages the very risk-taking that makes rescues necessary. The right way to reduce risk is to constrain liquidity creation before crises occur, since pricing emergency support correctly during a crisis is nearly impossible.

Data Points: Jackson Hole speech year: 2005 - Rajan’s warning about financial risk was delivered at Jackson Hole during Greenspan’s farewell conference. IMF chief economist tenure: 2003 to 2006 - Rajan described the IMF environment during the Great Moderation and emerging-market recovery. RBI governorship: 2013 to 2016 - He served during India’s taper-tantrum and inflation-targeting transition. India exchange rate depreciation: about 25% - The rupee fell sharply during the 2013 market turmoil. India inflation target zone: 2% to 6% - Rajan says inflation was brought into the target band by the end of his term. India inflation level by end of term: around 4% - He notes inflation fell from near double digits to mid-band inflation. Interest-rate increase used as signal: 75 basis points - Rajan says modest hikes were enough to signal seriousness without destabilizing growth. UPI monthly transactions: about 14 billion - He cites the scale of India’s payments system developed during his tenure. Fed reserves estimate in April 2008: $35 billion - Board staff estimate before QE and the floor system. Fed reserves estimate in November 2016: $300 billion - A later staff estimate of needed reserves under the new regime. Fed reserves estimate in November 2018: $1 trillion - Structural estimate rose sharply as the operating framework evolved. Fed reserves estimate in October 2019: $1.4 trillion - Further ratcheting of the estimated optimal reserve level. Implicit reserves estimate in current regime: $3 trillion - Current operating expectations imply a much larger reserve need. Fed balance sheet plus currency and TGA: about $6.5 trillion - Combined size cited when adding reserves, currency, and the Treasury General Account. Fed Treasury holdings: about $4.5 trillion - Rajan notes the Fed’s large holdings of government bonds. Fed Treasury holdings as share of GDP: 15% or more - Approximate macro scale of government bond holdings discussed. Repo crisis episode: September 2019 - Used as evidence that QT/withdrawal of liquidity can trigger stress. Pandemic stress episode: March 2020 - Fed responded with massive QE after market dysfunction. March 2023 banking turmoil: small and medium-sized banks; uninsured deposits - Referenced as a later episode consistent with liquidity dependence research. Currency franchise risk: stablecoins could displace physical currency - A possible future scenario discussed as a threat to Fed income and independence.

Pivotal Quotes: "the best time to nip risk-taking is at the beginning" — Raghu Rajan: He reflects on his early warnings before the global financial crisis and the limits of waiting until a collapse occurs. "Liquidity, liquidity everywhere, not a drop to use" — Host quoting Rajan paper title: The title captures the idea that reserves alone do not necessarily create usable liquidity for the real economy. "the system takes too much liquidity risk" — Raghu Rajan: Explaining the moral-hazard logic in which underpriced central bank backstops encourage excessive risk-taking.

Implications: The episode warns that large, persistent central-bank balance sheets can reshape bank funding, weaken market discipline, and create dependence on emergency liquidity. For policymakers, the challenge is limiting moral hazard before crises rather than relying on crisis-time rescue.
