MEMORANDUM BY FITCH IBCA
This written evidence has been submitted by
the Sovereigns Department of Fitch IBCA Limited, the international
credit rating agency. Fitch IBCA provides international credit
ratings for the foreign and local currency debt of over 60 sovereign
governments worldwide. Fitch IBCA's Sovereign Risk Report on the
UK was published in October 1999. The material below firstly sets
out in brief terms some aspects of public debt management which
are important in assessing sovereign credit risk and then offers
a few observations on public debt management policies from an
international perspective.
PUBLIC DEBT
MANAGEMENT AND
CREDIT RATING
2. When assessing the risk of default on
sovereign debt considerable attention is given to the structure
of public debt in addition to its overall level and trend. In
general a lower risk of default will be associated with a country
which has a low share of short term debt in its total debt stock
and a smooth profile of public debt maturities. These features
will mitigate the risks of governments facing difficulties in
persuading lenders to rollover their holdings of maturing public
debt. Deep and liquid government bond markets may also help reduce
debt service costs and reduce bond market volatility, although
the benefits of market depth obviously have to be assessed carefully
against the overall level of public borrowing.
3. The importance of the maturity structure
of debt can be illustrated by the example of Belgium, where Fitch
IBCA's sovereign credit rating was downgraded (from AA+ to AA-)
last December, on the eve of Belgium's entry to EMU. This reflected
the fact that, in addition to its high overall stock of public
debt, Belgium has a particularly high stock of short-term debtequivalent
to around 30 per cent of GDP. This increases its vulnerability
to liquidity and roll-over risks. These risks are significantly
more serious within EMU because the Belgium government can no
longer rely on a captive pool of domestic investors who demand
local currency assets, but rather have to compete with 10 other
sovereign governments issuing in the Euro. In addition, the scope
for central bank liquidity support is much more limited under
the "no bail out" clause in the Maastricht Treaty. Italy's
relatively low sovereign credit rating reflects similar concerns
about the maturity of its public debt. By contrast the UK's low
stock of short term public debt, as well as lower public debt
overall, means that rollover and liquidity risks are less of a
concern, allowing the government some flexibility in debt management
without fear of jeopardising credit worthiness.
4. Transparency in public debt management
is also important. Rating agencies look to the availability of
clear consolidated fiscal accounts, covering the total of government
debt liabilities, including publicly guaranteed debt. Transparency
is also important as regards the objectives of public debt managers
and their accountability to policy makers.
RECENT INTERNATIONAL
TRENDS IN
PUBLIC DEBT
MANAGEMENT
5. The introduction of the UK Debt Management
Office can be seen as part of a wider international trend towards
the establishment of autonomous or quasi-autonomous public debt
management agencies in the 1990s. Several OECD countries now have
autonomous agencies (see table), and the numbers are growing fastAustralia
and Greece have both established agencies in the last six months.
Even where debt management has remained an integral part of the
Finance Ministry or Central Bank, the general tendency has been
towards stronger recognition of debt management as a specialist
function and greater independence in pursuing debt management
objectives. And it is not just developed countries that have followed
this trendfor example in 1997 Hungary transferred responsibility
for managing foreign currency debt from the central bank to a
Government Debt Management Agency which is part of the Treasury.

6. Countries have expressed common aims in this process,
namely:
to improve transparency and reduce the risk of
political interference in debt management;
to raise the credibility of monetary policy by
mitigating potential conflicts of interest between the central
bank's debt management objectives and its monetary policy goals;
to exploit the advantages of specialisation in
risk management skills.
7. It is virtually impossible to isolate the impact of
the shift to greater autonomy in debt management from wider trends
in fiscal policy. But developments in debt management in recent
years generally appear to have been positive. For example some
smaller euro area countries such as Ireland, Austria and Portugal
have been successful in boosting market liquidity and improving
their standing with investors. These countries now have low levels
of short-term debt. And in Belgium, which now has an independent
debt management agency, more progress seems to have been made
in reducing debt and lengthening maturities than in other heavily
indebted euro area member states. In addition, the experience
of the Swedish National Debt Office in the early 1900s showed
that specialist public debt managers have the potential to outperform
external private sector debt managers in terms of reducing funding
costs. Hungary's move in 1997 has also been seen as greatly enhancing
the transparency of the public sector balance sheet. More generally,
by contributing to greater transparency in fiscal policy overall,
the shift to greater autonomy in debt management may have helped
to lock in the drive towards fiscal consolidation in recent years.
8. In conclusion, it would seem unrealistic to suggest
that the shift towards greater autonomy in public debt management
has, by itself, had a major impact on sovereign risk, relative
to the impacts of wider trends of fiscal consolidation. But to
the extent that it has contributed to greater transparency in
overall fiscal policy, more independence in pubic debt management
is likely to have been helpful.
