We talk about CBDC, the Swiss National Bank, whether CBDC would render it easier to implement helicopter drops, and how central bank profits should be distributed.

- Economic policy is not about GDP growth. It’s about welfare.
- Externalities are key. Infection externalities don’t go away by calling for responsible behavior. Infection externalities can turn positive.
- Keeping worthy companies or networks alive does not require government intervention, unless capital markets don’t work.
- To judge the right amount of burden sharing is beyond economics. But economics gives some clues: In an ideal world, idiosyncratic risk exposure would be insured while in second best, taxes and subsidies achieve only part of that. The data show that trade-offs between public health and economic activity are less severe than sometimes argued.

The Swiss National Bank—yes, the Swiss one—feels it must remind politicians of its independence. Parliamentarians from left to right (!) voice demands. To shrink the SNB’s balance sheet? No, for more central bank profits to be distributed sooner rather than later.
I discuss misconceptions, possible motivations, and a constructive response. «The best way to defend the independence of a central bank is never to exercise it.»

Clarifying the connections between outright monetary financing, QE, the distribution of seignorage profits, the relationship between fiscal and monetary policy, and central bank independence.

Monetary deficit financing is the norm—after all, central banks distribute their profits. Monetary financing occurs in the context of regular open market operations and QE and, hyper charged, with helicopter drops. The question is not whether monetary policy should finance the government, but why it does so, and to what extent. Fiscal and monetary policy are inherently connected; what constitutes monetary policy is defined by objectives.
Promising to do “whatever it takes” in order to avert a bad equilibrium is very different from printing money when the problem is a lack of resources, or their distribution.
See Gilles Saint-Paul’s “Whatever it Takes.”
For over a year the federal funds rate has increased relative to the rate the Fed pays on excess reserves. In mid September 2019, the federal funds rate increased abruptly, triggering the Fed to inject fresh funds. In parallel, the repo market rates spiked dramatically.
On the Cato Institute’s blog, George Selgin argues that structurally elevated demand collided with reduced supply. He mentions explicit and implicit regulation; Treasury General Account (TGA) balances; the NY Fed’s foreign repo pool (Japanese banks); and the administration’s $1 trillion deficit which required primary dealers to underwrite newly-issued government debt.
The bottom line is that regulators have managed to raise the biggest banks liquidity needs enough to compel them to sit on most of the banking system’s seemingly huge stock of excess reserves, and to do so even as repo markets present them with an opportunities to earn five times what those reserves are yielding just by lending them out overnight.
… So there you have it: a host of developments adding to banks’ demand for excess reserves, while others gradually chipped away at the stock of such reserves. Add a spike in primary dealers’ demand for short-term funding, a coinciding round of tax payments that transferred as many reserves to the TGA, and binding intraday liquidity requirements at the banks holding a large share of total system excess reserves, and you have the makings of last month’s perfect repo-market storm.
David Andolfatto and Jane Ihrig concur. On the Federal Reserve Bank of St. Louis’ On the Economy Blog, they already argued in March 2019 that banks feel compelled to hoard reserves rather than lending against treasuries:
Why should banks prefer reserves to higher-yielding Treasuries? One explanation is that Treasuries are not really cash equivalent if funds are needed immediately. In particular, for resolution planning purposes, banks may worry about the market value they would receive in the sale of or agreement to repurchase their securities in an individual stress scenario.
Consistent with this possibility, Federal Reserve Vice Chair for Supervision Randal Quarles noted, “Occasionally we hear that banks feel they are under supervisory pressure to satisfy their [high-quality liquid assets] with reserves rather than Treasury securities.”
To quantify this liquidity consideration, a recent post on the Federal Reserve Bank of New York’s Liberty Street Economics blog suggests that the eight domestic Large Institution Supervision Coordinating Committee’s banks collectively may want to hold $784 billion in precautionary reserves to cover their immediate liquidity needs in times of stress.
Andolfatto and Ihrig argue that the precautionary reserves hoarding by banks could substantially be reduced if the Fed offered a standing repo facility:
The Fed could easily incentivize banks to reduce their demand for reserves by operating a standing overnight repurchase (repo) facility that would permit banks to convert Treasuries to reserves on demand at an administered rate. This administered rate could be set a bit above market rates—perhaps several basis points above the top of the federal funds target range—so that the facility is not used every day …
With this facility in place, banks should feel comfortable holding Treasuries to help accommodate stress scenarios instead of reserves. The demand for reserves would decline substantially as a result. Ample reserves—and therefore the size of the Fed’s balance sheet—could in fact be much closer to their historical levels.
A standing repo facility could effectively impose a ceiling on repo rates. And as Andolfatto and Ihrig argue it would also have other benefits. In a follow up post, Andolfatto and Ihrig emphasize that,
[w]hile U.S. Treasuries are given equal weight with reserves in the calculation of high-quality liquid assets (HQLA) for the LCR, they are evidently not considered equivalent for resolution purposes.
Internal liquidity stress tests apparently assume a significant discount on Treasury securities liquidated in large volumes during times of stress, so that Treasuries are not treated as cash-equivalent. We have heard that banks occasionally feel under supervisory pressure to satisfy their HQLA requirements with reserves rather than Treasuries.
On the NewMonetarism blog, Stephen Williamson offers a longer-term perspective. He appears more skeptical as far as bank liquidity requirements as a possible explanation for the recent interest rate spikes are concerned. In Williamson’s view a floor system that requires even more reserves in the banking system than currently present is ineffective and should be replaced. He writes (my emphasis):
Before the financial crisis, the Fed intervened on the supply side of the overnight credit market by varying the quantity of its lending in the repo market so as to peg the fed funds rate. … a corridor system, as the central bank’s interest rate target was bounded above by the discount rate, and below by the interest rate on reserves, which was zero at the time. But, the Fed could have chosen to run a corridor by intervening on the other side of the market – by varying the quantity of reverse repos, for example. Post-financial crisis, the Fed’s floor system is effectively a mechanism for intervening on the demand side … With a large quantity reserves outstanding, those financial institutions holding reserves accounts have the option of lending to the Fed at the interest rate on reserves, or lending in the market – fed funds or repo market. Financial market arbitrage, in a frictionless world, would then look after the rest. By pegging the interest rate on excess reserves (IOER), the Fed should in principle peg overnight rates.
The problem is that overnight markets – particularly in the United States – are gummed up with various frictions. … Friction in U.S. overnight credit markets … is nothing new. Indeed, the big worry at the Fed, when “liftoff” from the 0-0.25% fed funds rate trading range occurred in December 2015, was that arbitrage would not work to peg overnight rates in a higher range. That’s why the Fed introduced the ON-RRP, or overnight reverse-repo, facility, with the ON-RRP rate set at the bottom of the fed funds rate target range, and IOER at the top of the range. The idea was that the ON-RRP rate would bound the fed funds rate from below.
… if total reserves outstanding are constant and general account balances go up, then reserve balances held in the private sector must go down by the same amount. The Fed permits these large and fluctuating Treasury balances, apparently because they think this won’t matter in a floor system, as it shouldn’t. … Another drain on private sector reserve balances is the foreign repo pool. … if the problem is low reserve balances in the private sector, those balances could be increased by about $300 billion if the Fed eliminated the foreign repo pool.
… The key problem is that the Fed is trying to manage overnight markets by working from the banking sector, through the stock of reserves. Apparently, that just won’t work in the American context, because market frictions are too severe. In particular, these frictions segment banks from the rest of the financial sector in various ways. The appropriate type of daily intervention for the Fed is in the repo market, which is more broadly-based. If $1.5 trillion in reserve balances isn’t enough to make a floor system work, without intervention through either a reverse-repo or repo facility, then that’s a bad floor system. … Make the secured overnight financing rate the policy rate, and run a corridor system. That’s what normal central banks do.

Huw van Steenis’ summarizes his report as follows (my emphasis):
A new economy is emerging driven by changes in technology, demographics and the environment. The UK is also undergoing several major transitions that finance has to respond to.
What this means for finance
Finance is likely to undergo intense change over the coming decade. The shift to digitally-enabled services and firms is already profound and appears to be accelerating. The shift from banks to market-based finance is likely to grow further. Ultra low rates, new regulations and the need to invest in updating their businesses mean many UK and global banks are struggling to make their cost of capital. Brexit and political and policy changes around the world will also impact the shape of financial services. Risks are likely to shift.
Regulators and the private sector have to collaborate in new ways as technology breaks down barriers. Finance is hugely important to the UK and the right infrastructure can support new finance.
What we ask the Bank of England to do
Shape tomorrow’s payment system
Enable innovation through modern financial infrastructure
Support the data economy through standards and protocols
Champion global standards for markets
Promote the smooth transition to a low-carbon economy
Support adaption to the needs of a changing demographic
Safeguard the financial system from evolving risks
Enhance protection against cyber-risks
Embrace digital regulation
- It is not central bank digital currency (CBDC) per se which might act as a game changer in financial markets. What will be key is how central banks accommodate the introduction of CBDC.
- In principle, this accommodation can go very far, to the point where the introduction of CBDC does not affect macroeconomic outcomes.
- But such complete accommodation is unlikely. On the one hand, central banks will want to exploit the new monetary policy options that CBDC opens up; that is, central banks will not choose to fully accommodate.
- On the other hand, the introduction of CBDC increases transparency and this will increase political pressure; as a consequence, central banks will not be able to fully accommodate.

- Modern monetary theory (MMT) is neither a theory, nor modern, nor exclusively monetary.
- I discuss fallacies related to MMT.
- Dynamic inefficiency requires permanent, not transitory, r<g.
- For now, policy makers should rely on common sense rather than MMT.
In a Staff Working Paper, the Bank of England’s Philip Bunn, Alice Pugh, and Chris Yeates discuss how monetary policy easing following the financial crisis affected income and wealth of different age groups.
The authors analyze survey panel data (ONS Wealth and Assets Survey) on households’ characteristics and balance sheet positions. They argue that
the overall effect of monetary policy on standard relative measures of income and wealth inequality has been small. Given the pre-existing disparities in income and wealth, we estimate that the impact on each household varied substantially across the income and wealth distributions in cash terms, but in percentage terms the effects were broadly similar. We estimate that households around retirement age gained the most from the support to wealth, but that support to incomes disproportionately benefited the young. Overall, our results illustrate the importance of taking a broad-based approach to studying the distributional impacts of monetary policy and of considering channels jointly rather than in isolation.
In an NBER working paper, Arvind Krishnamurthy, Stefan Nagel, and Annette Vissing-Jorgensen analyze which components of bond yields were affected by the European Central Bank’s government bond purchasing programs.
Given the institutional restrictions on monetary policy in the Euro area, the ECB had to carefully argue why it intervened in the first place. (To many, the case was obvious; the ECB intervention amounted to quasi-fiscal policy. But an intervention with this objective would not be covered by the rules of the Euro area.) It gave two reasons for the SMP, OMT, and LTRO:
The ECB has publicly stated that these policies reduce redenomination risk, i.e., the risk that the Eurozone might break up and countries redenominate domestic debt into new domestic currencies, and financial market “dysfunctionality,” i.e., segmentation- and illiquidity-induced pricing anomalies.
The authors decompose bond yields into five components: an expectations hypothesis component; a euro-rate term premium; a default risk premium; a redenomination risk premium; and a component due to sovereign bond market segmentation. To identify the non-observable, country-specific components (reflecting default risk, redenomination risk, and sovereign bond market segmentation), the authors use information from asset prices that are differentially exposed to these components.
Specifically, they use the fact that
foreign-law sovereign bonds denominated in US dollars cannot be redenominated through domestic law changes … and redenomination into a new currency should affect all securities issued in a given country under the country’s local law equally.
The authors find that
the default risk premium and sovereign bond segmentation effect appear to have been the dominant channels through which the SMP and the OMT affected sovereign bond yields of Italy and Spain. Redenomination risk may have been present at times and it may have been a third policy channel for the SMP and OMT in the case of Spain and Portugal, but not for Italy. … default risk accounts for 30% of the fall in yields across SMP and OMT for Italy. Segmentation accounts for the other 70%. For Spain, the numbers are 42% (default risk), 15% (redenomination risk) and 43% (segmentation). For Portugal, the numbers are 40% (default risk), 24% (redenomination risk) and 36% (segmentation). For the LTROs, we find that their effect on Spanish bond yields worked almost entirely via the sovereign segmentation channel. We show that the more substantial impact of the LTROs on Spanish sovereign yields than on Italian and Portuguese sovereign yields is consistent with Spanish banks purchasing a larger fraction of outstanding sovereign debt in the months following the introduction of the LTROs.
In a CEPR discussion paper, Christoph Trebesch and Jeromin Zettelmeyer argue that
ECB bond buying had a large impact on the price of short and medium maturity bonds … However, the effects were limited to those sovereign bonds actually bought. We find little evidence for positive effects on market quality, or spillovers to close substitute bonds, CDS markets, or corporate bonds.
A multiple equilibria view of the crisis would probably suggest otherwise.
In an ECB occasional paper, Ulrich Bindseil, Marco Corsi, Benjamin Sahel, and Ad Visser review the European Central Banks’s collateral framework.
From the executive summary, on misconceptions:
… differences e.g. with interbank repo markets: first, central banks are not subject to liquidity risk in the way “normal” market participants are, and can therefore accept less liquid collateral. Second, as the central bank has a zero default probability in its domestic market operations, collateral providers are willing to accept severe haircuts to obtain credit. …
According to the authors the ECB is the most transparent central bank when it comes to its collateral framework. But the latter is also complicated:
However, it is true that the ESCF is relatively broad in terms of the scope of eligible collateral and rather complicated. This is inevitable because of the diversity of financial institutions and markets in the euro area.
In a VoxEU eBook, Refet Gürkaynak and Cédric Tille collect the views of central bank and academic economists on DSGE models. In the introduction to the eBook, Gürkaynak and Tille summarize these views as follows:
… there is agreement on the place of DSGE models in policy analysis. All see these models as part of the policymaker tool kit, while understanding their limitations and perceiving a similar road ahead.
On VoxEU, Luca Benati, Robert Lucas, Juan Pablo Nicolini, and Warren Weber argue that long-run money demand in many countries is rather stable.
… using a specific, narrow monetary aggregate, M1, we study a dataset comprising 32 countries since the mid-19th century (Benati et al. 2016). The main finding of this large-scale investigation is that, contrary to conventional wisdom, in most cases statistical tests do identify with high confidence a long-run equilibrium relationship between either M1 velocity and a short-term interest rate, or M1, GDP, and a short rate – that is, a long-run money demand.
The Economist reports that implementation gradually changes:
[T]he way in which the People’s Bank of China conducts monetary policy is changing. It is beginning to look a little more like central banks in developed economies as it shifts towards liberalised interest rates. Rather than simply ordering banks to set specific lending or deposit rates—the focus for many years in China—it is altering the monetary environment around them. China does not yet have an equivalent of the federal-funds rate in America or the refinancing rate in Europe, but it has a few candidates for its new benchmark interest rate. The seven-day bond-repurchase rate, which influences banks’ funding costs, is in pole position.
There is also an element of political intrigue in this transition to a more mature monetary framework. The Chinese central bank sits under the State Council, or cabinet, which has the final say over lending and deposit rates as well as other big policy decisions. Repo rates, by contrast, are seen as sufficiently abstruse for the central bank to decide on its own when it wants to change them.
In the NZZ, Kjell Nyborg questions whether the collateral values of the securities the ECB accepts in monetary policy operations reflect market values. He argues that the valuation is discretionary and politicized.
Meine Analyse macht deutlich, dass der Besicherungsrahmen in der Euro-Zone in unterschiedlicher Ausprägung unter all diesen Problemen leidet. Das öffentliche Verzeichnis der zulässigen notenbankfähigen Sicherheiten enthält 30 000 bis 40 000 verschiedene Wertpapiere, von Staatsanleihen bis hin zu unbesicherten Bankanleihen und forderungsbesicherten Wertpapieren (Asset-Backed Securities). Die überwiegende Mehrheit dieser Wertpapiere hat keinen Marktpreis. Ungefähr ein Drittel all dieser Sicherheiten wird in nichtregulierten Märkten gehandelt. Zudem können Banken nichtmarktfähige Anlagen und Wertpapiere mit «privaten Ratings» verwenden, die nicht im öffentlichen Verzeichnis sind. Daher basieren die Werte der Sicherheiten mehrheitlich auf Modell- statt auf Marktpreisen. Interessanterweise ziehen Banken es vor, Sicherheiten zu benutzen, bei denen häufiger theoretische Preise verwendet werden. Generell tendiert die Besicherungspolitik der Euro-Zone zu risikoreichen und illiquiden Sicherheiten. Die untergeordnete Rolle des Marktes sieht man auch an der Häufigkeit, mit welcher die Sicherheitsabschläge für die Repo-Geschäfte des Euro-Systems aktualisiert werden: Dies geschieht lediglich alle drei bis vier Jahre.
Im Kern des Geldsystems in der Euro-Zone gibt es somit wenig Spielraum für Marktkräfte oder Marktdisziplin. Insgesamt kann die Besicherungspolitik des Euro-Systems als expansiv beschrieben werden. Die Liste notenbankfähiger Sicherheiten ist äusserst umfangreich und oft auf die «Bedürfnisse» von Banken in verschiedenen Ländern zugeschnitten. Sicherheiten können, zum Beispiel, durch Staatsgarantien aufgewertet werden. … Weil es im Kern des Euro-Geldsystems an Marktkräften und Marktdisziplin fehlt, entsteht ein Vakuum, das von anderen Kräften, wie Rating-Agenturen und der Politik, aufgefüllt wird.
… Ich dokumentiere, dass DBRS eine ausschlaggebende Rolle innehatte, indem sie über eine lange Zeit hinweg Italien und Spanien ein Rating von A– und Portugal ein solches von BBB– gab. Das hob den Wert der in diesen Ländern begebenen Sicherheiten um ungefähr bis 200 Mrd. € an und kann als unterstützende Massnahme für indirekte Bail-outs interpretiert werden.
Im Dezember 2011 und Februar 2012 hat die EZB eine ihrer wichtigsten geldpolitischen Massnahmen vor dem Beginn des Quantitative Easing implementiert. … Um aus dieser Möglichkeit Vorteil zu schlagen, hat die italienische Regierung gleichzeitig eine präzedenzlose Anzahl von Garantien für Bankanleihen mit niedrigem oder gar keinem Rating gesprochen. Damit erhöhte sie deren Besicherungswert. Darüber hinaus hat die EZB mehr als 10 000 unbesicherte, auf nichtregulierten Märkten gehandelte Bankanleihen der öffentlichen Liste notenbankfähiger Sicherheiten hinzugefügt, obwohl der aggregierte Wert notenbankfähiger Sicherheiten die Nachfrage von Banken nach Zentralbankgeld schon bei weitem überstieg.
In the 18th Geneva Report on the World Economy, Laurence Ball, Joseph Gagnon, Patrick Honohan and Signe Krogstrup ask whether “central banks can do [more] to provide stimulus when rates are near zero; and … whether policies exist that would lessen future constraints from the lower bound.”
They are optimistic and argue that the unconventional policies of recent years can be extended: “[I]t is likely that rates could go somewhat further than what has been done so far without adverse consequences” and “[m]ore stimulus can be provided if policymakers increase the scale of quantitative easing, and if they expand the range of assets they purchase to include risky assets such as equity.” While the authors concede that QE might have negative side effects they argue that the benefits are worth the costs.
To relax the zero lower bound constraint in the future, Ball, Gagnon, Honohan and Krogstrup argue in favor of a higher inflation target. They view cashless societies as not imminent but possible.
