SNB Strategy Update

With its annual report from a few weeks ago the SNB communicated minor changes in its monetary policy strategy (p. 24):

The review of the monetary policy strategy showed that it has fundamentally proved its worth. There was no need to adjust the first two elements, namely the definition of price stability and the conditional inflation forecast. The strategy has enabled the SNB to fulfil its mandate of price stability well, despite repeated strong external shocks in recent years. The definition of price stability has allowed the SNB to react flexibly to such shocks and to weigh up the costs and benefits of monetary policy measures. The conditional inflation forecast has also proved its worth as the main indicator for the orientation of monetary policy and as a tool for its communication. It summarises the need for monetary policy action and helps to communicate monetary policy decisions in an understandable manner.

The formulation of the third element, however, has been adjusted. The SNB implements its monetary policy by setting the SNB policy rate. The third element now explicitly provides for the SNB to also use additional monetary policy measures to influence the exchange rate or the interest rate level, if necessary. With this adjustment, the SNB is taking into account the increased importance of such measures in recent years. Until now they have been mentioned in explaining the strategy, but were not explicitly included in the third element.

As part of this review, the SNB also decided to hold a news conference following every monetary policy assessment, in order to explain the monetary policy decision to the public in greater detail. This change was implemented for the first time at the September assessment.

In my NZZ article from August 2021 I had concluded (in German):

Daher ist eine Strategieüberprüfung inner- und ausserhalb der SNB sinnvoll. Geldpolitisch prüfenswert sind das Inflationszielband, die Zentralität des Zinsinstruments und die Kommunikation. Die Glaubwürdigkeit der SNB verbietet ein Auseinanderklaffen von Theorie und Praxis, aber auch allzu häufiges und detailversessenes Feilen an der Strategie, und sie verlangt Konzentration auf das Wesentliche. Gleichzeitig sollte die SNB ihre Bindung an den – gegebenenfalls sich wandelnden – Willen des Gesetzgebers betonen. Bei Fragen, die nicht allein in ihre Zuständigkeit fallen, muss sie klarstellen, dass sie Partei und nicht Schiedsrichterin ist. Damit die SNB auch in Zukunft zu den grossen Schweizer Erfolgsgeschichten zählt, muss sie von Zeit zu Zeit über die Bücher gehen. Doch alleine kann sie die Verantwortung in Geld- und Währungsfragen nicht tragen.

The title of that article was “Die Nationalbank ist an vielen Fronten gefordert”. Online, the NZZ added “—die Schweizerische Nationalbank braucht eine neue Strategie”.

Monetary Policy, the NK Model, and Humility

In an NBER working paper John Cochrane concludes that

… we have been guilty of playing with too-complex models when we don’t really understand basics, such as stability, determinacy, and the frictionless limit. …

Given the state of actual agreed-on knowledge, central banks’ proclamations of detailed technocratic ability to manipulate delicate frictions is laughable. Figure 10 shows in chart form the Rube-Goldberg list of mechanisms the ECB thinks it understands and can manipulate. Central bankers who think they have any idea how all these boxes and arrows work, and how to manipulate them, should reread Bob’s unsung classic “on a report to the OECD” Lucas (1979) once a week. A little humility would do us all good.

Doves and Hawks at the ECB

In the FAZ, Christian Siedenbiedel discusses a ZEW study on the positions of ECB board members and how they relate to national debt levels.

Es gibt klare Fraktionen von „Falken“ und „Tauben“ im Rat, und es gibt eine gewisse Korrelation zur Höhe der Staatsschulden im jeweiligen Heimatland des Ratsmitglieds. Als „Tauben“ wurden nach der Daten-Auswertung die Ratsmitglieder Ignazio Visco (Italien), Pablo Hernández de Cos (Spanien), François Villeroy de Galhau (Frankreich), Giannis Stournaras (Griechenland und Mario Centeno (Portugal) eingestuft. Auf der anderen Seite bestehe die klare „Falken“-Fraktion aus Jens Weidmann (Deutschland), Robert Holzmann (Österreich), Klaas Knot (Niederlande), Pierre Wunsch (Belgien) und Martins Kazaks (Lettland).

Die Klassifizierung der EZB-Direktoriumsmitglieder, die ebenfalls dem Rat angehören, zeige ein gemischteres Muster, heißt es in der Studie. So vertrat beispielsweise Isabel Schnabel (Deutschland) eine gemäßigtere Position als ihr deutscher Kollege im Gremium, Bundesbankpräsident Jens Weidmann. Das umgekehrte Muster gelte für Spanien, wo der Vizepräsident Luis de Guindos gemäßigter sei als sein eher „taubenhaft“ eingestellter Kollege, der Notenbankchef Hernandez de Cos. EZB-Präsidentin Christine Lagarde wird in der Studie als „Taube“ eingestuft, da sie sich auf die Fortführung des PEPP konzentriere und alle Arten von Debatten über einen vorzeitigen Ausstieg, die von der Falkenfraktion kämen, strikt ablehne. „Obwohl für sechs Ratsmitglieder nur unzureichende Daten zur Verfügung standen, deutet unsere Kategorisierung darauf hin, dass es im EZB-Rat eine Mehrheit von Tauben gibt“, heißt es in der Studie. …

Die Taubenfraktion im Rat kommt auf eine durchschnittliche Schuldenquote in ihren Heimatländern von 133 Prozent, fast dem Doppelten der Falkenfraktion mit 71 Prozent. Den Zusammenhang haben die Wissenschaftler dann noch statistisch abgesichert. „Unser Ergebnis zeigt eine klare Korrelation zwischen heimischer Staatsverschuldung und Positionierung“, sagt Studienautor Friedrich Heinemann.

Should the SNB follow the Fed and the ECB and rework its strategy? There is a case for rethinking the broad inflation target, the monetary policy concept, and the communication strategy. Equally important is a strategy review outside of the SNB: The SNB cannot and must not decide about the framework within which it operates.

Conclusion:

Daher ist eine Strategieüberprüfung inner- und ausserhalb der SNB sinnvoll. Geldpolitisch prüfenswert sind das Inflationszielband, die Zentralität des Zinsinstruments und die Kommunikation. Die Glaubwürdigkeit der SNB verbietet ein Auseinanderklaffen von Theorie und Praxis, aber auch allzu häufiges und detailversessenes Feilen an der Strategie, und sie verlangt Konzentration auf das Wesentliche.

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.

“Unabhängigkeit der Nationalbank (Independence of the SNB),” FuW, 2020

Finanz und Wirtschaft, July 25, 2020. PDF.

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.»

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.

U.S. Money Markets

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.

The Bank of England’s “Future of Finance Report”

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.

  • For now, policy makers should rely on common sense rather than MMT.

Monetary Policy and the Wealth Distribution

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.

ECB Bond Purchases: Fiscal or Monetary Policy?

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.

Price Effects of Purchases of Greek Sovereign Debt by the ECB

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.

ECB Collateral Framework

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.

DSGE Models for Monetary Policy Analysis

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.
