Rebuilding Social Capital: the role of Central Banks remarks by Governor Gabriel Makhlouf at the 175th Anniversary of Banco de Portugal

01 April 2022 Speech

Governor Gabriel Makhlouf

Boa tarde,

Banco de Portugal’s Money Museum is certainly an appropriate place to discuss today’s topic. The museum’s focus on the relationship between money, individuals and human societies is at the core of the role of central banks in building (or indeed rebuilding) social capital.1

Back to the beginning

What is social capital? There are many definitions and the history of the concept goes back to Adam Smith, de Tocqueville and even Aristotle.2

Ultimately, it’s about how people connect to one another.

I like to think of it as “the social connections, attitudes and norms that contribute to societal wellbeing by promoting coordination and collaboration between people and groups in society."3

This is still very nebulous for an audience of economists (and I will avoid discussing payoff matrices, dominant strategies, and game theoretic equilibria to make my point!).4 But social capital is essential to what we – central banks – do every day and why we do it.

To understand why, it is worth going back to the beginning.

Central banks today have many functions but, fundamentally, they exist to provide monetary stability.

In 1668 the world’s oldest central bank, Sveriges Riksbank, was “founded from the ruins of Stockholms Banco” a failed private bank.5 Shortly afterwards in 1694 “the Bank of England began as a private bank that would act as a banker to the Government. It was primarily founded to fund the war effort against France.”6

Many of the early central banks were established to deal with monetary disarray.

Political and financial turmoil provides the context for the establishment of the Banco de Portugal 175 years ago.

In 1846 the Portuguese State was on the “brink of bankruptcy”, the country was in civil war and as the museum exhibits explain “the armies of the Provisional Junta of the Supreme Government of the Kingdom, based in Porto, were advancing towards Lisbon in order to remove the new government of Costa Cabral.”7 The Bank was granted the power to issue banknotes convertible into hard currency.

The Banque de France “was established by Napoleon in 1800 to stabilize the currency after the hyperinflation of paper money during the French Revolution, as well as to aid in government finance. Early central banks issued private notes which served as currency, and they often had a monopoly over such note issue.”8

Money is a symbol of stability and central banks play an important role in maintaining this stability.  It may be obvious but it’s worth saying: the stability of money plays a critical role in the stability of society.

The role of money (as a store of value, a unit of account and a medium of exchange) is also an important instrument in how we connect with each other, through trade, commerce, and our everyday interactions and hence in building social capital.

In more recent history, the later wave of central banks were established at the turn of the 20th century and brought together the many instruments that people were using for currency and to provide financial stability.9 While central banks at this time were constrained by the gold standard, they “learned to act as lenders of last resort in times of financial stress—when events like bad harvests, defaults by railroads, or wars precipitated a scramble for liquidity (in which depositors ran to their banks and tried to convert their deposits into cash).”10

As we chart the history of central banks, we can see their critical role providing stability, both monetary and financial.  I will discuss considerations beyond monetary and financial stability later in my remarks.

One point I would like to reiterate now is who central banks serve. This is an important anchor when thinking about the role of central banks in building (or rebuilding) social capital.

Since becoming Governor of the Central Bank of Ireland, a guiding principle for me has been a phrase from the original legislation establishing the Central Bank of Ireland in 1942.

Echoing the State’s Constitution, it stated that the Central Bank’s “constant and predominant aim shall be the welfare of the people as a whole”.11

But I will return to that later.

Institutions matter

Taking a step back, if social capital is ultimately about how we connect with one another, it’s clear that institutions matter for building social capital.  And central banks, as important institutions of the State, play a critical role. In fact, I suggest that central banks are part of an institutional ecosystem that is interconnected, notwithstanding that the individual components may act independently. We do not act in a vacuum, and we should not confuse independence with isolation.

Douglass North defined institutions as the “humanly devised constraints that structure political, economic and social interactions”.12

Economists from Adam Smith, to Ronald Coase, Mancur Olsen and, more recently, Daron Acemoglu and James Robinson, have explained how institutions are critical for the rule of law, property and civil rights, economic development, economic stability, and solving information and co-ordination problems across communities and societies.13

Surrounding us today are also pre-monetary exhibits of the museum’s collection which include treasures like Kuba cloths, a form of money from Congo in the 17th century.

I think this is a good example to explain my thinking on how money’ as an institution is a key instrument in building social capital.

Kuba cloths, with their bold graphic patterns, I learned, were time-intensive to make, and created by many members of the community – stripping and kneading the raffia fibres, colouring, weaving and embroidering. They were not simply a means of payment, but used as clothing, offerings, rewards and dowries.14

Conceptually we can think about institutions from many perspectives.

Old institutions include money, law or contracts.

Other examples of institutions include the concept of nation states, representative democracy, or written constitutions.

Newer institutions include the United Nations, EU treaties and the Law of the Sea.

Modern institutions include the World Trade Organisation and the concept of independent central banks.

I like how Andy Haldane put it: “whether old or new, institutions seem to matter. Their secret lies in solving societal problems of knowledge, co-ordination and incentives. Institutional memory can help lengthen and strengthen otherwise short and subjective minds. And institutional investment can help build public goods and flatten otherwise fat tails.”15

Trust and social capital

One common thread that enables all institutions to work is trust.

Without the trust of the public that it serves, an institution will struggle to function, to be effective, and, ultimately, to persist.

Institutional trust “is a key element of a resilient society and is critical for implementing effective policies, since public programmes, regulations and reforms depend on the co-operation and compliance of citizens”.16

Why is this important for central banks?

Kenneth Arrow in 1972 explained that “virtually every commercial transaction has within itself an element of trust, certainly any transaction conducted over a period of time. It can be plausibly argued that much of the economic backwardness in the world can be explained by the lack of mutual confidence”.17

Walking around the museum I also saw the only known specimen of a silver leais struck in the Oporto mint and introduced during the reign of King Afonso V (r. 1438-1481). This coin was introduced during a period of relative monetary stability in Portugal from the 1420s on “following decades of wars against Castile, successive currency debasements and inflation.”18

The silver leais as suggested by its name means ‘loyal’ or ‘honest’.

Trust is as critical today for central banks, as it was for King Afonso V.

Trust is essential for the transmission of monetary policy. Trust affects the public’s (and financial markets’) inflation expectations which are an important anchor and determinant of price stability. Trust affects the legitimacy of central banks, particularly that of the ECB as a supranational institution.19

50 years on Kenneth Arrow’s assertions still hold true. To buy something over the internet, you not only need to trust the vendor – that they will deliver the goods as promised – but also the legitimacy of the website, the security of the technology platform and the payments system to make the transfer. If people do not even trust the currency in which they are paying, the ecosystem will not function.

Like the monetary system, the financial system relies on trust and confidence.

Central banks and regulators have a key role in ensuring the integrity of the regulatory and supervisory frameworks which safeguard the stability of the financial system, and often the protection of consumers.

A lack of trust weakens the central bank and makes it vulnerable to political pressure.20

So central banks, like all institutions, need to build trust and build social capital.

This is necessary to ensure we continue to be effective in the delivery of our mandate for the “welfare of the people as a whole”.

Communications

How do we do this?

Expectation-setting requires a central bank to communicate clearly both its objective and how it intends to achieve it.  Yet it is always a challenge: “with a more ideological public, more polarised politics, and more fractionalised parliaments, central banks face growing demands for greater accountability, enhanced political engagement, and greater understanding.”21

Transparency, honesty and engagement help to build credibility and to set expectations.

This requires, in turn, that the public understand the mission of central banks, recognises the importance of that mission, and trusts in its commitment to deliver.  All this requires effective central bank communication.22

Growing our social capital requires us to communicate in a way that is understandable to people, and to speak to issues that resonate with people and not just financial markets.

Nor can we rely on ‘old intermediaries’ alone.

Traditional communication channels are disappearing so we must navigate new channels effectively between central banks and the wider public to allow different narratives to emerge. Adapting to new channels, new platforms, new ways to target our communications and deliver our messages.23

Some questions for today

Demands for greater trust, transparency, accountability, legitimacy, and rebuilding of social capital all come at a time of rapid change.

Technological change is disrupting the landscape of financial services, with new entrants, new business models, a race by incumbents to invest in developing the necessary capabilities, and in many cases the potential for a fundamental disruption in the value chain of traditional financial services firms and sectors. This has impacted different sectors such as the retail banking sector, payment and e-money firms as well as new emerging areas such as crypto.  The ECB’s own ‘Digital Euro’ project is a recognition of this changing landscape, and what it might mean for money, for central banks themselves and for citizens.24

At the same time the mandates of central banks have increased significantly.  In the euro area most national central banks are also competent authorities for the supervision of banks, and also resolution authorities.

Moreover, and taking the Central Bank of Ireland as an example, we are the competent authority for the funds sector, the insurance sector, and the national macroprudential authority.  We also play an important role in the State’s framework for consumer protection and exercise enforcement powers.

The broadening of our mandate beyond monetary and financial stability – and giving us responsibilities which more directly and closely interact with the lives of the public – places a greater onus on us to build social capital, not least at a time of significant change.

This is relevant to a number of issues that we are considering today.

Social capital is stronger when institutions respond to, or even lead, key issues of the day.

Aiming to simply preserve institutions can lead to weakening them.

While all institutions need to change, we must make sure expectations on institutions are not misaligned, as this would lead to an erosion of social capital.

Some of the key issues highlighted for today’s discussion include the distribution of income and climate change.

I will not get into the data on inequality or the risks from climate change. I think these are well known.

I would however like to discuss the role of central banks.

Intergenerational economics: climate change and inequality

Reflecting on the impact of the pandemic and the significant economic transitions that started before it and remain ahead of us (climate change and demographic change in particular), it is clear that they require long-term and more integrated thinking across a number of dimensions.25

We need to be thinking broadly and over longer time horizons to fully capture the trade-offs we face, not least because many of these challenges also require a global policy response.26

Policies to address climate change, for example, may appear costly in a short time horizon, but deliver large net benefits in a longer horizon that makes clear the benefits of avoiding catastrophic increases in global temperatures.

Central banks are acting in response to the climate challenge.

We’re embedding climate change considerations into our supervisory assessments.

This is about ensuring the true environmental and indeed societal costs of climate change are factored-in appropriately, whether the design of insurance policies or the granting of credit or something else.27

We're broadening our understanding of the nature and magnitude of financial risks stemming from environmental change and how interlinkages across the economic and financial system might amplify these risks.

We're working with our domestic and international partners to ensure that green and sustainable financial products are defined appropriately and identifiable to investors.

Our goal is to ensure that climate change is a strategic priority for the financial system, and that the financial system is resilient to the risks posed by climate change and capable of supporting the transition to a lower-carbon world.

Central banks need to play their part and lead by example in their own actions, as well as deliver on their mandate to ensure that the financial system is resilient to climate-related risks and ready to support the transition to a more sustainable world.

But let us also be clear: central banks cannot solve the problem of climate change.

The challenge requires action on the part of the whole community, businesses, households, as well as policymakers.

Inequality is another issue for today’s panel and both income and wealth inequality have been increasing in many advanced economics since the 1980s.

As my colleague on the ECB’s Governing Council, Isabel Schnabel, has outlined, there are two factors which can explain income inequality trends. These are the effects of technological development in the labour market – with less-skilled workers experiencing lower wage growth than those with higher education levels – and the reduction in bargaining power for workers.28

Inequality is something that central banks need to pay close attention to, not least because it does have economic consequences as well as implications for social capital and the public’s trust in a state’s institution

Monetary policy decisions inevitably affect financial markets, and the wider economy. This is why central banks must have a clear mandate, which in the case of the euro area is of course price stability.

We also conduct proportionality assessments, which include analysis on the benefits and the possible side effects of monetary policy measures, their interaction and their balance over time.

Overall, central banks do not have the mandate or the tools to deal with societal concerns around excess income or wealth inequality.29 Governments are best placed to address the concerns in their societies around these developments.

But we do need to ensure that while we take our decisions with a clear goal in mind, we also understand the side effects of our actions and that they do not outweigh the benefits.

Conclusion

There are three things I suggest we should bear in mind.

First, central banks need trust to succeed. Trust is stronger where social capital is strong. Central banks can help build social capital through their actions.

Second, social capital is an important determinant of a community’s wellbeing, alongside human capital, natural capital and financial and physical capital.  (I like to describe these capitals as our collective “economic capital”30 but that is a subject for another day.)

An important fact is that social capital does not grow on its own.  An economy, a society and its environment are all complex systems that constantly interact with each other. Societies need to invest in economic, social and environmental infrastructures – including institutions such as central banks – to enable social capital to grow.

Third, stasis is not an option. The frameworks we operate with, the ideas that “ramify … into every corner of our minds”, must be capable of change.31 As I said, preserving institutions could also weaken them. Our challenge is to understand how and when our frameworks need to change. We need to be ready to challenge familiar paradigms, as one way of eroding social capital is to ignore the need for change.

So where does this leave us?

Well for me, back to the beginning and back to the present.

Back to the beginning, in the sense that at their core central banks exist to provide monetary stability.

Back to the present, in that inflation has continued to surprise on the upside because of unexpectedly high energy costs.

The path for our monetary policy will continue to be determined by the Governing Council’s commitment to stabilise inflation at two per cent over the medium term.

Price stability is the best contribution central banks can make to ensuring stability for the ‘welfare of the people as a whole’.

Like King Afonso’s leais, we need to be loyal to this objective.

And like weaving a Kuba cloth, we must constantly build and rebuild social capital to achieve this.

To paraphrase José Saramago – who once wrote that the history of Portugal was not that of Europe but that the history of Europe would be unimaginable without that of Portugal32 – the history of central banks is not that of social capital but strong social capital would be difficult to deliver without successful central banks.

I look forward to the discussion.

Obrigado.
