(Last updated September 2, 2025.) It’s hard not to notice the similarities between the 1920s and 2020s economy. Does that mean trouble is coming in 2029? Maybe not exactly, but roughly? If so, the severity of the shock will … Continue reading →

In the early 1900s, depositors ran on banks.
We fixed that with FDIC insurance and regulation.
In 2007-8, lenders ran on shadow banks.
We haven’t fixed that yet.
In fact we’ve made it worse.

“The events of March 2020 provide evidence of structural instability in the repo market …because the repo market is now so large, in a crisis it acts as a coordination device generating an overwhelming volume of sell orders that all demand to be filled simultaneously.

“The particular crisis of 2007–2009 manifested itself in new forms of short-term debt runs in which repurchase agreements, commonly known as repos, played a major role.

“So-called ‘repos’ are a way for borrowers to raise short-term funding by agreeing to buy and sell securities over very short timeframes. In practice they function as short-term loans and are a vital, under-appreciated lubricant of the financial system.” — Robin Wigglesworth in the Financial Times, January 3, 2019.

“Panic-type phenomena occurred in a variety of contexts in the recent financial crisis. … Of particular concern were funding pressures in the critical market for repurchase agreements (repos), which are used heavily by broker-dealers and others to finance credit holdings.” Ben Bernanke, Brookings Institution, September 2018.
*****
“Although the deterioration of household balance sheets and the associated deleveraging likely contributed to the initial economic downturn and the slowness of the recovery, I find that the unusual severity of the Great Recession was due primarily to the panic in funding and securitization markets, which disrupted the supply of credit.” — Ben Bernanke, “The Real Effects Of The Financial Crisis,” September 13-14,2018.

“Prior to the crisis, repo was a lightly regulated multi-trillion dollar market which funded nearly half of the asset holdings by the major investment banks.” – Gary Gorton, Toomas Laarits, Andrew Metrick, “The Run On Repo and The Fed’s Response,” July 2018.
*****
“Bank regulation since the 2008 crisis has taken a wrong turn. In response to widespread condemnation of ‘bailouts,’ Congress included stringent new restrictions on Fed lending in the Dodd-Frank Wall Street Reform Act of 2010. … it is vital to the future safety of the financial system that Congress correct its 2010 mistake.” – Laurence M. Ball, The Fed and Lehman Brothers: Setting the Record Straight on a Financial Disaster, 2018.
*****
“The 2008 crises on Wall Street were 21st century versions of bank runs. They originated with bad investments in real estate, but losses from these investments were not the direct cause of Lehman’s sudden collapse or of the near-collapses of the institutions that the Fed chose to rescue. Instead, the fatal development was a loss of confidence by other financial institutions, which led them to suddenly refuse to renew short-term loans that Lehman and the other distressed firms needed to operate.” – Laurence M. Ball, The Fed and Lehman Brothers: Setting the Record Straight on a Financial Disaster, 2018.
*****
“When mortgage defaults started rising, many financial institutions experienced a run on their short-term liabilities.

A standard narrative “has it that the financial meltdown of 2008 was caused by an overextension of mortgages to weak borrowers, repackaged and then sold to willing lenders drawn in by faulty risk ratings for these mortgage back securities. To many, mortgage backed securities and rating agencies became the key villains of that financial crisis,” but this is wrong, write Juan Ospina of Banco de la Republica de Colombia and Harald Uhlig of the University of Chicago in “Mortgage-Backed Securities And The Financial Crisis of 2008: A Post Mortem,” April 2018.
*****
“The 2007-2008 Financial Crisis was a horrific global preview of the consequences of depending on repo-based funding when the financial system becomes vulnerable to risk. Repo funding drove the entire American financial system into the foster care of the federal government.” — Kurt Dew, Seeking Alpha, Visiting lecturer, Northeastern University, April 11, 2018.

“A financial crisis is an event in which the holders of short-term debt come to question the collateral backing that debt.” — “Collateral Damage,” Gary Gorton and Toomas Laarits, Yale School of Management, February 2018.
*****
“In a classic banking panic, holders of demand deposits want their cash back because they do not trust the value of the banks’ loan portfolios backing the deposits. Deposit insurance solves this problem. In the crisis of 2007-8 the holders of short-term debt, in the form of repo, came to distrust the bonds used as collateral and increased haircuts, generating a run on the banking system.” — “Collateral Damage,” Gary Gorton and Toomas Laarits, Yale School of Management, February 2018.

“Runs present a sadly familiar set of perils when they happen to regulated and protected banks. They create more complicated perils when they happen to other types of financial institutions that are less regulated, as was the case in the United States before the 2008 crisis.” –Timothy Geithner, “Are We Safe Yet?” January/February 2017.

“Excessive use of repos can indeed weaken the financial system by facilitating the use of short-term funding and the build-up of leveraged positions backed by collateralized borrowing. It can also increase the interconnectedness within the financial system.” — The Bank of International Settlements, April 12, 2017.

“Today, it is not the heavily regulated traditional commercial banks that are the main source of concern. Rather, it is the lightly regulated nonbank financial institutions that are deeply reliant on uninsured short-term debt that pose significant risk.” — Paul Volcker and the Volcker Alliance, “Unfinished Business, Banking In The Shadows,” December 5, 2016.
*****
“At the heart of the crisis were contagion effects … and the withdrawal of much of the short-term wholesale funding on which many large financial firms and the shadow banking system had come to rely. … The period was defined by runs, not on bank deposits (at least not insured bank deposits), but on short-term wholesale funding … investors refused to roll over existing repurchase agreements (or repos) and similar extensions of credit, much less to offer new lending.” — Federal Reserve Governor Daniel Tarullo, December 2, 2016.

“Data describing bilateral repurchase agreements and securities lending were scant in the run up to the financial crisis, and they still are.” — Richard Berner, director, Office of Financial Research. October 27, 2016.
*****
“The crisis brought to light unique risks from the excessive use of short-term wholesale funding and repo agreements in particular …. Looking back, it is easy to see how certain behaviours and market practices necessitated government intervention with wholesale funding and collateral management reforms becoming a cornerstone of global regulators’ post-crisis efforts to reduce risk in the financial system.” — James Slater, global head of
securities finance at BNY Mellon Markets, Securities Lending Times. September 29, 2016.
*****
“I continue to believe that the post-crisis work to create a solid regime to protect financial stability cannot be deemed complete without a well-considered approach to regulating runnable funding.” — Federal Reserve Governor Daniel Tarullo. July 12, 2016.

“After four years of efforts, regulators and the financial firms with the most at stake have failed to extinguish systemic risk in a crucial short-term lending market (the repurchase market} that greases the wheels of trading in U.S. Treasuries.” — Liz McCormick, Bloomberg. May 25, 2016.

*****
“Data gaps persist in securities financing transactions, including repo and securities lending. The markets for these critical short-term funding instruments remain vulnerable to runs and asset fire sales. Yet comprehensive data on so-called bilateral repo and securities lending transactions are scant.” — Richard Berner, Director, Office of Financial Research. April 12, 2016.

“Market interest rates are effectively determined in the collateral market, such as the repo, or repurchase market, where banks and other financial institutions exchange collateral (such as US Treasuries, mortgage securities, corporate debt, equities) for money.” –Manmohan Singh, Financial Times, November 23, 2015.
*****
“In many ways, repos are the building blocks of financial markets. To mess with repo is to mess with the DNA of the markets.” — Andy Hill, International Capital Market Association. September 2015.
*****
“The market for repurchase agreements is an elemental building block of modern financial markets. Whether used as a money market instrument, a source of funding, a means of mobilising collateral, or the transmission mechanism for monetary policy, it is difficult to think of any financial instrument or derivative that is not impacted in one way or another by repo rates.” — Andy Hill, International Capital Market Association. September 2015.
*****
“Nearly half of the liabilities of broker-dealers consist of short-term wholesale funding (repo and securities lending), an amount that is nearly the same as it was during the crisis.” — Federal Reserve Governor Daniel Tarullo, Brookings Institution, November 17, 2015.
*****
“I also believe that the greatest risks to financial stability are the funding runs and asset fire sales associated with reliance on short-term wholesale funding … If there is one lesson to be drawn from the financial crisis, it is that the rapid withdrawal of funding by short-term credit providers can lead to systemic problems as consequential as those associated with classic runs on traditional banks.” — Federal Reserve Governor Daniel Tarullo, Brookings Institution, November 17, 2015.

“Given its vast scale and position at the center of the wholesale finance markets, repo is without doubt a critical activity. ” — Federal Reserve Governor Jerome Powell, Clearing House Annual Conference, November 17, 2015.
*****
“For the most part, the main problems during that (financial) crisis didn’t involve banks that offered both commercial and investment services. Instead, the problems were primarily at traditional investment banks. Had Glass-Steagall remained in place, the financial crisis would almost surely have happened anyway.” — Mark Thoma, MoneyWatch, November 16, 2015.

“Despite of its systemic importance, the repo market remains opaque to most market participants, including even the regulators. Because no official data on repos exists, questions as basic as the overall size of the market are difficult to answer.” — Grace Xing Hu, Jun Pan, Jiang Wang, Tri-Party Repo Pricing, August 2015.

Financial panics are increasing in frequency. While they used to be driven by depositors lining up to get their money, nowadays, “the problem is that institutional creditors do the same thing in the repo market.” — John Maxfield, The Motley Fool, March 19, 2015.

“The repo market, the largest short-term funding market … still remains susceptible to asset fire sales and runs.” — Office of Financial Research, December 2014.

“While regulated banks have faced far tighter oversight following the financial crisis, the shadow-banking market remains a source of potential instability. It is worth remembering that runs here, rather than traditional bank runs, were a cause of the crisis and led to seizures of credit markets.” — David Reilly, Wall Street Journal, February 19, 2013.

*****
“Repo has a flaw: It is vulnerable to panic, that is, ‘depositors’ may ‘withdraw’ their money at any time, forcing the system into massive deleveraging. We saw this over and over again with demand deposits in all of U.S. history prior to deposit insurance. This problem has not been addressed by the Dodd-Frank legislation. So, it could happen again.
