Structure and Management of Public Debt in Nigeria


AHAM NZENWATA

Governments in developing countries are faced with a myriad of challenges in their drive to improve infrastructure and achieve economic development. Among these challenges is the problem of how to accumulate the needed capital to fund developmental projects and also ensuring that the capital so accumulated is “sufficient” in order to contribute significantly to the economic growth objectives of policy makers.

In trying to deal with the problem of capital accumulation, the government relies principally on revenue generated through economic activities within the country. But this is hardly ever enough to generate the huge amount of capital that is required to achieve the government’s development objectives. Thus, the inability of the government to accumulate a sufficient amount of capital through revenue generation gives rise to the need for governments to borrow.

As noted in Ezirim (2005), when the government’s actual revenue performance falls short of projected estimates, government resorts to borrowing to finance projects of social and economic importance to the nation. Gbosi (1998) also noted that the need to finance rising government expenditure was responsible for the rapid increase in the stock of Nigeria’s public debt.

Gurley and Shaw (1956) stated that the mounting volume of public debt is a necessary feature of a strong and healthy financial structure in a market based economy. But went on to caution that such borrowing should as much as possible be planned. From the above, it can be deduced that for a development oriented government in a market based economy, borrowing to finance budgetary shortfalls is unavoidable.

As noted by Onoh (2007), deficit budgeting is now a deliberate policy direction employed by governments in developing countries. However, he also stated that countries that resorted to borrowing especially from external sources to finance budgetary shortfalls have recorded varying degrees of success or failure in their use of this tool. While some recorded some measure of success in improved production and consequently higher employment levels, others have resulted in higher inflationary pressures, weak domestic currencies, capital flight chronic deficit in balance of payments and negative savings.

The implication is that borrowing by government is a policy option that should be used with utmost care in order not to trigger adverse economic conditions that may not have been intended in the first place. With this in mind, it is important to note that public debt consists of two components viz – domestic and external debt. Both involve different mechanisms and interact differently with the economy.

Domestic debt implies the government issuing debt instruments such as treasury bills, treasury certificates, development stocks and bonds locally and denominated in the local currency.  By definition, external debt refers to the portion of a country's debt that was borrowed from foreign lenders including commercial banks, governments or international financial institutions (Ajayi & Khan, 2000).

These loans, including interest, must usually be paid in the currency in which the loan was made. According to Odozi (1996), domestic debt is the gross liability of government, and properly considered should include Federal, State and Local governments transfer obligations to the citizens and corporate firms within the country.

On the other hand, external debt arises as a result of the government sourcing funds outside the shores of the country. According to Rais and Anwar (2012), while external borrowing increases the country’s access to new financial resources, domestic borrowing only transfers resources within the country. In other words, domestic borrowing only change hands of money holders while the volume of money within the country remains the same.

Nigeria like many other developing countries has over the years relied heavily on borrowing to finance huge capital intensive projects. A cursory look at the structure of Nigeria’s debt structure both domestic and external indicates a gradual increase in public debt from 1981 to 1998.

In 1999 total debt spiked upwards to N3.37 trillion from the previous year’s 1.19 trillion representing about a 182% increase. It is also instructive to note that external borrowing is largely responsible for this upward spike, increasing from 1998’s N688 billion to N2.57 trillion in 1999.

Nigeria’s total public debt peaked in 2004 at N6.26 trillion before dropping to N3.18 trillion in 2006. Nigeria’s public debt data published by the CBN also indicated that domestic debt constituted a whopping 82% of the total public debt. But by 2004, domestic share of the total debt had dropped to about 21.89% and rose again to about 86.84% of the total by 2010.

Available data from the Debt Management Office (DMO) shows that Nigeria’s total debt stock (addition of external and domestic debts) as at December 31, 2011 stood at N6,510bn representing an increase of 24.37% from the December 31, 2010 figure of N5,235bn. A breakdown of the debt stock shows that external debt accounted for 13.64% of the total debt stock at N887.95bn, while domestic debt stock accounted for 86.36% of the total debt stock at N5, 623bn.

The total public debt stock in the country as at December 2011 is estimated at about 17.50% of the GDP, as against the applicable critical limit of 40% for countries in Nigeria’s economic peer group (FSDH, 2012). It is important to note at this point that the Debt Management Office has set a target of not exceeding a GDP to Debt ratio of 30%.

Data on fixed capital formation as published in the CBN Statistical Bulletin (2012) showed that from inception gross fixed capital formation has been on an upward trend except for a few intermittent years when it had shown a reduction from the previous year. For example in 1981, Nigeria’s expenditure in provision of fixed capital was N18.2 billion.

This value dropped consistently through the next few years until it reached its lowest value at N8.79 billion in 1985. It rose to N11.35 billion in 1986, N15.22 billion in 1986 and N17.56 billion in 1987. The upward trend continued until it peaked in 2010 at N4.012 trillion before dropping to N3.357 trillion in 2012.

In the next section, we will explore the structure of Nigeria's public borrowing using graphs, charts and tables.


The data presented in this section are those relating to the characteristics and trends of the data involved in this study. The information generated in this section gives a clear indication of the trends and characteristics in the Gross Fixed Capital Formation, Domestic and External Debt in Nigeria for the period of the study (1981-2012).

FIGURE 4.1:        Gross Fixed Capital Formation (GFCF) Trend for the Period of the Study (1981-2012)

Figure 4.1 above shows the trend in Gross Fixed Capital Formation (GFCF) for the period 1981 to 2012. The figure shows that in 1981, Nigeria’s expenditure in provision of fixed capital was N18.2 billion. This value dropped consistently through the next few years until it reached its lowest value at N8.79 billion in 1985. It rose to N11.35 billion in 1986, N15.22 billion in 1986 and N17.56 billion in 1987. The upward trend continued until it peaked in 2010 at N4.012 trillion before dropping to N3.357 trillion in 2012. See Table 4.1 above.

FIGURE 4.2:        Total Long-Term Debt for the Period of the Study (1981-2012)

Total Long-Term Debt rose at a slower gradient in the earlier years. From its initial value of N5.68 billion in 1981, it rose steadily to N824.86 billion in 1995, it dropped to N697.70 billion in 1999 before spiking upward to N3371.64 billion in 2000. Total long-term debt attained its highest value in 2004 at N5282.46 billion before dropping to N2371.63 billion in 2008. Currently (2012), it has a value of N5441.51 billion.
















FIGURE 4.3:        Nigeria’s Long-Term Domestic and External Debt Trend for the Period of the Study (1981-2012)


Figure 4.3 show trends in Nigeria’s Long-Term External and Domestic Debt for the period of the study. It shows that external debt maintained a much higher value than Domestic Debt from 1981 to 2004. Following the debt repayment agreement between the Federal Government and the London and Paris Club of Creditor in 2004, External Debt Dropped from its record high of N4783.71 billion in 2004 to N431.08 billion in 2007. Before resuming an upward trend again in 2008 but at a much gentler gradient than in previous years. In   2012, the value stood at 1026.90 billion. The figure also show that for the first time in 2006, Total Domestic Debt Assumed a higher value at N1058.26 billion  against External debt’s N386.63 billion. To date, domestic debt has continued to be higher than external debt.
















FIGURE 4.4:        Nigeria’s Total Debt to GDP Ratio for the Period (1981-2010)

Figure 4.4 above show Nigeria’s Total Public Debt to GDP ratio from 1981 to 2010. It shows that Nigeria’s total debt to GDP ratio rose from about 28% in 1981 and consistently grew to about 142% in 1991. Of the 1991 value, external debt accounted for about 105% of the total. From 1992 until 1996, the total debt to GDP ratio assumed a downward trend dropping to 38% in 1996 before spiking upwards to 106% in 1999. Since then, total debt to GDP ratio has continued to drop. Presently (2010), it stands at 18% of GDP. The figure above also indicate that













FIGURE 4.5:        Nigeria’s External Debt to GDP Ratio for the Period of the Study (1980-2010)
              
Figure 4.5 above shows that the trend in External Debt to GDP ratio for the period of the study almost mirrors the trend in Total Debt to GDP. This is probably because external debt is the dominant component of Nigeria’s public debt. For example, of the total of 130%, 133%, 143%, 142% and 136% Total Debt to GDP ratio in 1988, 1989, 1990, 1991 and 1992 respectively, External Debt accounted for 96%, 111%, 112% and 105% and 102%.

















FIGURE 4.6:        Structure of Nigeria’s Public Debt From 1997-2012

Figure 4.6 shows the structure of Nigeria’s Long-Term Public debt from 1997 to 2012. It shows that in 1997, Nigeria’s Total Long-Term Debt comprised of about 80% External Debt and 20% domestic debt. This value rose to about 85% in 1999, it maintained values in the 85% to 91% range from 1999 to 2004. In 2006, it fell to 27% and fell even lower to about 17% in 2010.
