When a tin-foil-hat-wearing blog full of
digital dickweeds suggest the dollar's reserve currency status is at best
diminishing, it is fobbed off as yet another conspiracy theory (yet to
be proved conspiracy fact) too horrible to imagine for the status quo huggers.
But when the VP of Research at the New York Fed asks "Could the dollar lose its status as
the key international currency for international trade and international
financial transactions," and further is unable to say why not, it
is perhaps worth considering the principal contributing factors she warns
of.
Could the
dollar lose its status as the key international currency for international trade
and international financial transactions, and if so, what would be the principal
contributing factors?
Speculation about
this issue has long been abundant, and views diverse. After the introduction of
the euro, there was much public debate about the euro displacing the dollar (Frankel 2008). The monitoring and
analysis included in the ECB’s reports on “The International Role of the Euro”
(e.g. ECB 2013) show that the international
use of the euro mainly progressed in the years prior to 2004, and that it has
largely stalled since then. More recently, the euro has been displaced by the
renminbi as the debate’s main contender for reducing the international role of
the dollar (Frankel 2011).
This debate has
mainly argued in terms of ‘traditional’ determinants of international currency
status, such as country size, economic stability, openness to trade and capital
flows and the depth and liquidity of financial markets (Portes and Rey 1998). Considerations
regarding the strength of country institutions have more recently been added to
the list. All of these factors influence the ability of currencies to function
as stores of value, to support liquidity, and to be accepted for international
payments. Inertia also plays a role (e.g. Krugman 1984, Goldberg 2010), raising the bar for currencies
that might uproot the status quo.
We argue here – building on discussions we began
during the World Economic Forum Summit on the Global Agenda 2013 – that the rise
in global financial-market integration implies an even broader set of drivers of
the future roles of international currencies. In particular, we maintain that
the set of drivers should include the institutional and regulatory frameworks
for financial stability.
The emphasis on
financial stability is linked with the expanded awareness of governments and
international investors of the importance of safety and liquidity of related
reserve assets. For a currency to have international reserve status, the related
assets must be useable with minimal transaction-price impact, and have
relatively stable values in times of stress. If the risk of banking stress or
failures is substantial, and the potential fiscal consequences are sizeable, the
safety of sovereign assets is compromised exactly at times of financial stress,
through the contingent fiscal liabilities related to systemic banking crises.
Monies with reserve-currency status
therefore need to be ones with low probabilities of twin sovereign and financial
crises. Financial stability reforms can – alongside fiscal prudence – help
protect the safety and liquidity of sovereign assets, and can hence play a
crucial role for reserve-currency status.
The broader
emphasis on financial stability also derives indirectly from the expanded
awareness in the international community of the occasionally disruptive
international spillovers of centre-country funding shocks (Rey 2013). We argue that regulatory
reforms can play a role in influencing these spillovers.
Resilience-enhancing
financial regulation of global banks can help reduce the volatility of capital
flows that are intermediated through such banks.
On
financial stability and reserve-currency status
International
reserve assets tend to be provided by sovereigns, notably due to the fiscal
capacity of the state and the credibility of the lender of last resort function
of the central bank during liquidity crises (see also De Grauwe 2011 and Gourinchas and Jeanne 2012). Systemic financial
events can be accompanied by pressures on the government budget, however. While
provision of a fiscal backstop to the banking sector is not the best ex ante
approach to policy, fiscal support will tend to be forthcoming if the risk and
estimated welfare costs of a systemic fallout are otherwise deemed too high.
Yet banking sector
risks – and inadequate capacity within the banking sector to absorb these risks
– can end up exceeding a government’s ability to provide a credible fiscal
backstop without adversely affecting the safety of its sovereign assets. The
fiscal consequences of bailouts may result in increased sovereign risk and the
loss of safe-asset status, with implications for the status of the currency in
question in the international monetary system.
To increase the
likelihood that sovereign assets remain safe during systemic events, the
sovereign can undertake financial and fiscal reforms that decouple the fiscal
state of the sovereign from banking crises. Such reforms should achieve, in
part, a reduction in the likelihood of and need for bailouts through increased
resilience and loss absorption capacity of the financial system, and by ensuring
sufficient fiscal space for credible financial-sector support (see also Obstfeld 2013).
Reform
initiatives
A number of
current reform initiatives already take steps in this direction. These
include:
- Reforms to bank capital and liquidity regulation, which reduce the likelihood that financial institutions, and notably systemically important ones (SIFIs), become distressed;
- Initiatives that seek to counteract the procyclicality of leverage, and to strengthen oversight; and
- Recovery and resolution regimes for distressed systemically important financial institutions (SIFIs) are being improved.
Importantly,
initiatives are underway to improve recovery and resolution in the international
context. While a global agreement on cross-border bank resolution is currently
not in place, bilateral agreements among some pairs of countries are being
forged ex ante to facilitate lower-cost resolution ex post. Further, the
resilience of the system as a whole is being strengthened, to better contain the
systemic externalities of funding shocks. Examples include:
- The strengthening of the resilience of central counterparties and other financial market infrastructures; and
- The foreign currency swap arrangements among central banks to provide access to foreign currency funding liquidity at times when market prices of such liquidity are punishingly high.
Nevertheless,
the financial system contains vulnerabilities – globally, as well as in
individual currency areas. The negative sovereign banking feedback
loop may be weakened in many countries, but has not been fully severed.
Moreover, reforms are not necessarily evenly implemented across countries.
Fiscal capacities to provide credible backstops of the financial sector during
stress vary widely. The consequences of recent reforms for the future of key
international currencies are therefore open. Scope remains for countries vying
for reserve-currency status to use the tool of financial stability reform to
protect the safety and liquidity of their sovereign assets from the contingent
liabilities of financial systemic risk.
Financial
stability reforms matter for spillovers and capital flows
International
capital flows yield many advantages to home and host countries alike. Yet the
international monetary system still faces potential challenges stemming from
unanticipated volatility in flows, as well as occasionally disruptive spillovers
of shocks in centre-country funding conditions to the periphery. With the events
around the collapse of Lehman Brothers, disruption in dollar-denominated
wholesale funding markets led to retrenchment of international lending
activities. Capital flows to some emerging-market economies then recovered with
a vengeance as investors searched for yield outside the countries central to the
international monetary system, where interest rates were maintained at the zero
lower bound. After emerging markets were buoyed by the influx of funds, outflows
and repositioning occurred when markets viewed some of the expansionary policies
in the US as more likely to be unwound.
While
macroprudential measures – and in extreme cases, capital controls – are some of
the policy options available for addressing the currently intrinsic
vulnerabilities of some capital-flow recipient periphery countries (IMF 2012), we point out that these vulnerabilities
can also be addressed in part by financial stability reforms in centre
countries.
Consider, for
example, the consequences of the regulatory reforms pertaining to international
banks that are currently being proposed or implemented. Improvements in the
underlying financial strength and loss-absorbing capacity of global banks could
have the beneficial side-effect of reducing some of the negative spillovers
associated with unanticipated volatility in international banking flows –
especially those to emerging and developing economies. Empirical research
suggests that better-capitalized financial institutions, and institutions with
more stable funding sources and stronger liquidity management, adjust their
balance sheets to a lesser degree when funding conditions tighten (Gambacorta and Mistrulli 2004, Kaplan and Minoiu 2013). The result extends to
cross-border bank lending (Cetorelli and Goldberg 2011, Bruno and Shin 2013).
While financial
stability reforms may reduce the externalities of centre-country funding
conditions, they retain the features of international banking that promote
efficient allocation of capital, risk sharing and effective financial
intermediation. By enhancing the stability of global institutions and reducing
some of the amplitude of the volatility of international capital flows, they may
address some of the objections to the destabilising features of the current
system.
Cross-border
capital flows that take place outside of the global banking system have recently
increased relative to banking flows (Shin 2013). Regulation of global banks does very
little to address such flows, and may even push more flows toward the
unregulated sector. At the same time, however, regulators are considering
non-bank and non-insurer financial institutions as potential global
systemically-important financial institutions (Financial Stability Board 2014).
Conclusions
We have argued
that the policy and institutional frameworks for financial stability are
important new determinants of the relative roles of currencies in the
international monetary system. Financial stability reform enhances the safety of
reserve assets, and may contribute indirectly to the stability of international
capital flows. Of course, the ‘old’ drivers of reserve currencies continue to be
influential. China’s progress in liberalising its capital account,
and structural reforms to generate medium-term growth in the Eurozone – as
examples of determinants of the future international roles of the renminbi and
the euro relative to the US dollar – will continue to influence their
international currency status. Our point is that such reforms will
not be enough. The progress achieved on financial stability reforms in major
currency areas will also greatly influence the future roles of their
currencies.
