Namibia: Staff Report for the 2011 Article IV Consultation–Debt Sustainability analysis

Namibia’s government has launched a major three-year fiscal initiative in 2011 aimed at increasing growth and employment. Public debt is rising rapidly, from a low base. The authorities intend to unwind the fiscal expansion in 2014. Fiscal consolidation would help keep public debt to a manageable level, support the economy’s external position, and provide room to maneuver if further shocks arise, including a potential fall in revenues from the Southern African Customs Union. The authorities reaffirmed their intention to support the exchange rate peg against the South African rand.

Abstract

Namibia’s government has launched a major three-year fiscal initiative in 2011 aimed at increasing growth and employment. Public debt is rising rapidly, from a low base. The authorities intend to unwind the fiscal expansion in 2014. Fiscal consolidation would help keep public debt to a manageable level, support the economy’s external position, and provide room to maneuver if further shocks arise, including a potential fall in revenues from the Southern African Customs Union. The authorities reaffirmed their intention to support the exchange rate peg against the South African rand.

DEBT SUSTAINABILITY ANALYSIS

1. Namibia’s public debt for FY2010/11 is estimated at about N$13.5 billion (16.2 percent of GDP). About 24 percent of the debt is owed to bilateral, multilateral and private foreign creditors while the rest is domestic debt. Before its recent rise, public debt had fallen from 26 percent of GDP in 2005/6 to 15.5 percent in 2009/10, with domestic debt declining from 22.2 percent of GDP to 11.5 percent over the same period. However, the current expansionary stance of fiscal policy is projected to increase debt sharply, bringing overall public debt to 35.3 percent of GDP in FY2016/17. Further upside risks stem from a potential future decline in SACU revenues.

2. Table 2 shows two scenarios:

  • The first scenario shows the fiscal outcome if real GDP growth, real interest rates, and the primary balance remain at their historical 10-year averages. In this case, the public debt to GDP would only reach 19.8 percent of GDP by 2016, reflecting the relatively more benign historical levels of the key variables, including the prudent fiscal stance over the last decade.

  • The second scenario shows the fiscal outcome if government’s policies in 2010 remain unchanged, with the primary deficit standing at 3.6 percent of GDP throughout the medium term. In this case, public debt rises sharply to 59 percent of GDP, thereby breaching the authorities’ indicative limit of 35 percent of GDP.

Indicate coverage of public sector, e.g., general government or nonfinancial public sector. Also whether net or gross debt is used.

Derived as [(r – π(1+g) – g + αε(1 +r)]/(1 +g+π+gπ)) times previous period debt ratio, with r = interest rate; π = growth rate of GDP deflator; g = real GDP growth rate; α = share of foreign-currency denominated debt; and ε = nominal exchange rate depreciation (measured by increase in local currency value of U.S. dollar).

The real interest rate contribution is derived from the denominator in footnote 2/ as r – π (1 +g) and the real growth contribution as –g.

The exchange rate contribution is derived from the numerator in footnote 2/ as αε(1+r).

For projections, this line includes exchange rate changes.

Defined as public sector deficit, plus amortization of medium and long-term public sector debt, plus short-term debt at end of previous period.

The key variables include real GDP growth; real interest rate; and primary balance in percent of GDP.

Derived as nominal interest expenditure divided by previous period debt stock.

Assumes that key variables (real GDP growth, real interest rate, and other identified debt-creating flows) remain at the level of the last projection year.

3. The bounds tests reveal the vulnerability of the fiscal position to exogenous shocks (Figure 1). The most benign shock is that stemming from a negative growth shock (decline from 4.3 percent to 2.6 percent) which could result in a 12 percentage point increase in the debt to GDP ratio. Public debt is also highly sensitive to shocks to the primary balance and contingent liabilities.

4. Namibia’s external debt is projected to increase somewhat by 2016, yet remain at a moderate level. In 2011, external debt is estimated to have increased by 3 percentage points to 23 percent of GDP, largely reflecting the substantial deterioration in the external position as well as the recent issuance of the Eurobond by the government (US$500 million). The debt ratio is set to remain on an upward trajectory over the medium-term and reach 25 percent of GDP in 2016 as the current account deficits—although moderating—are projected to persist. In this regard, the impact of the current account deficits on the external debt’s trajectory is projected to remain modest, as a large share of the projected imports are related to foreign direct investment in the mineral sector.

5. The rising external debt ratio increases the vulnerability of the economy to external shocks, although risks remain manageable. Stress tests suggest that Namibia’s external debt is mostly sensitive to a persistent non-interest current account shock, which would increase the external debt ratio to 44 percent of GDP. This scenario, which could be interpreted as a sharp drop in external demand for Namibia’s mineral exports in the event of a protracted global slowdown, should be seen as the upper bound estimates, particularly given that a standard DSA scenario does not capture the likely impact of such a shock on relative prices. A one-off depreciation of 30 percent, as well as a scenario that combines a relatively moderate shock to both current account balance and GDP growth, are also estimated to sharply increase the debt ratio to around 40 percent of GDP by 2016. In contrast, a separate shock to GDP growth and interest rates is projected to have a relatively moderate impact on the external debt’s trajectory.

Derived as [r - g - ρ(1 +g) + εα (1+r)]/(1 +g+p+gp) times previous period debt stock, with r = nominal effective interest rate on external debt; ρ = change in domestic GDP deflator in US dollar terms, g = real GDP growth rate, ε = nominal appreciation (increase in dollar value of domestic currency), and α = share of domestic-currency denominated debt in total external debt.

The contribution from price and exchange rate changes is defined as [–ρ(1 +g) + εα(1+r)]/(1+g+p+gp) times previous period debt stock. ρ increases with an appreciating domestic currency (ε > 0) and rising inflation (based on GDP deflator).

For projection, line includes the impact of price and exchange rate changes.

Defined as current account deficit, plus amortization on medium- and long-term debt, plus short-term debt at end of previous period.

The key variables include real GDP growth; nominal interest rate; dollar deflator growth; and both non-interest current account and non-debt inflows in percent of GDP.

Long-run, constant balance that stabilizes the debt ratio assuming that key variables (real GDP growth, nominal interest rate, dollar deflator growth, and non-debt inflows in percent of GDP) remain at their levels of the last projection year.
