We analyse the potential balance of payments (BoP) impact of lower oil prices (an oil price shock) for a selection of 16 oil exporters. We assess the current account impact through the loss of export revenues and compare this to the current level of international reserves for each country. The estimated current account impact relative to reserves provides a simple indicator of external vulnerability and gives us a sense of the likelihood and extent of any resulting BoP liquidity crisis. We caution, however, that this is a static analysis and may therefore overstate the actual impact (for example, we ignore any offsetting policy response to mitigate the loss of export revenues) and we ignore the financial account shock on the BoP too, which could be even more severe for those with large gross external financing needs, although we think this still serves as a useful exercise to assess where vulnerabilities might reside.

Modelling approach

Put simply, a 50% fall in the oil price translates into a 50% fall in oil export revenues, other things equal. This would, again ceteris paribus, translate to an equivalent change in reserves (or fall in reserves compared to the baseline). However, the current account impact would also depend on the extent of oil dependence. If oil makes up the vast majority of a country’s exports (which it does in Angola, Iraq, Kuwait and Nigeria), then this translates virtually to a 1:1 fall in total exports. However, if oil makes up only a small share of overall exports (for example, Indonesia, Ghana and Colombia), the impact on total exports is scaled similarly and becomes less significant overall (assuming unchanged non-oil exports). The overall current account impact would also depend on changes in other current account items, while the overall BoP impact would further depend on other BoP flows, although for simplicity we ignore those impacts here.

For our estimated current account impact, we calculate oil export revenues for each country as the product of oil prices and oil export volumes, and measure the loss of oil export revenues in our shock scenario by the price differential, assuming volumes are unchanged. For oil prices, we take as our baseline the pre-crisis 2020 forecast, given by either the national government's budget assumption, the latest IMF country report or the October IMF WEO projection. The pre-coronavirus average oil price assumed for 2020 across our sample is cUS$58/bbl. For our oil price shock, we assume an annual average oil price in 2020 of US$35/bbl; we note that the new IMF WEO published yesterday assumes about the same price based on oil futures (US$35.61 in 2020). Given oil prices averaged around US$50/bbl in Q1 (US$51 for Brent, US$47 for WTI), this implies average prices in the low 30s for the rest of the year. Clearly there is some uncertainty around the outlook, although we note that production cuts agreed at the OPEC+ meeting last Thursday do not appear to have changed the price outlook significantly at this stage given global demand pressures. Hence, on average, the fall in oil prices in our oil price shock scenario is of the order of 40% compared to the baseline, although there are marked differences across countries, depending on the initial projection.

We proxy oil export volume through oil production and share of oil exports in oil production, where available. For oil production, we use as our baseline the pre-crisis 2020 forecast, given by either the national budget assumption, the latest IMF country report, or if unavailable, the latest reported oil production figure. We assume production is unchanged in response to the oil price shock so the loss of oil export revenues is given simply by the difference in price multiplied by volume. This assumption may, however, prove invalid now in light of the new OPEC+ production cuts, although a country-by-country breakdown of revised quotas or production targets is not yet available and it is too early to assess the degree of compliance. We note, however, that some producers under the OPEC+ agreement risk suffering from a combined price and volume shock to the extent that oil prices do not respond as intended.

There are two other things to note in our analysis. First, we only look at the impact through gross oil exports rather than through net oil exports, so we might therefore overstate the current account impact for countries that also import oil. The oil price shock reduces the oil import bill as well as reducing oil export revenues. Second, we do not model the impact on gas exports here, which could also be significant in some cases (eg in our sample Kazakhstan, Trinidad and Indonesia are significant gas producers too). However, the nature of gas pricing makes this assessment harder to do. These factors are particularly relevant to Indonesia, an energy exporter, because of its gas exports but a net oil importer despite being an oil exporter.

For the current level of international reserves, we take the latest available pre-crisis level of reserves from national central banks, Haver or IMF reports where available. 

Results – Angola and Ecuador are the most vulnerable

Countries that are more dependent on oil exports (major oil producers and with greater share of oil in total exports) and/or with relatively low levels of reserves to start with are – obviously – the most vulnerable to a protracted period of low oil prices, and hence loss of oil export revenues; while the low level of reserves may limit their ability to respond appropriately, or quickly enough, to the shock. Our results are summarised in Figure 1 and shown in detail in Table 1 (see full report). 

Angola and Ecuador are the most vulnerable countries in our sample, whereby the current account impact (fall in oil exports) from the oil price shock is enough virtually to wipe out their already low level of reserves. For Angola, the estimated current account impact as a share of reserves is 95%. We estimate the current account impact from a projected loss of oil exports is cUS$11bn, which is about the same as the country's net international reserves. For Ecuador, the estimated current account impact as a share of reserves is 90%. We estimate the current account impact from a projected loss of oil exports is about US$3.0bn, compared to total foreign reserves of US$3.3bn. Moreover, both countries find themselves with limited room for manoeuvre as they pursue economic adjustment programmes with the IMF, with Angola suffering from a high public debt ratio (and a pegged exchange rate) and Ecuador (which is dollarised) facing a heavy debt service schedule on its international bonds. Ecuador has already quickly preempted this looming liquidity challenge by seeking a bond restructuring after struggling to keep on track with the IMF programme in its previous review. 

Nigeria, Iraq, Bahrain, Oman and CEMAC countries (Gabon and Republic of Congo, especially) are also vulnerable. For Nigeria, Iraq, and Oman the projected fall in oil exports from the oil price shock is about half of their respective reserves, while it is even higher for Bahrain (about two-thirds). In the CEMAC region, while the fall in oil exports for individual countries looks modest relative to the region’s total (pooled) reserves, the cumulative export loss is about two-thirds of total reserves. Hence, the cumulative impact from individual countries could have implications for macroeconomic stability of the region as a whole, and the CFA currency peg; a re-run of the 2014-2016 oil price shock which forced CEMAC members, under international pressure, to adopt IMF programmes in order to help restore regional stability. In particular, at a country level, the projected fall in oil exports for Gabon and Republic of Congo may exceed their imputed reserves (their share of the region’s reserves).

At the other end of the scale, the projected current account impact relative to reserves is negligible for Indonesia and relatively minor for Cameroon, Egypt and Colombia. The impact on Trinidad is also minor although we think that is because we ignore the impact on gas exports.

We also benchmark our results for the current account impact against the latest IMF WEO projections (released yesterday). We plot the estimated current account impact according to our model as a share of projected nominal US$ GDP (based on WEO forecasts) against the projected change in the current account as a share of GDP between 2019 and 2020 according to WEO forecasts (Figure 3). Our projections are broadly consistent except mainly for Iraq, Kuwait and Trinidad where the IMF project a much larger current account impact this year.

Policy responses

This static approach may, however, overstate the actual impact, as we do not account for offsetting effects that might help to mitigate the loss of export revenues (either through active policy decisions or elsewhere, eg through volume effects, reduced imports, or other balance of payments flows). In particular, there are a number of policy choices to ameliorate an expected current account deterioration:

  1. Policy adjustment. EM Countries might ordinarily be expected to tighten macroeconomic policy in response to a current account shock (procyclical policy response) in order to reduce imports and/or cut government spending to limit the fiscal impact from the revenue loss (where oil revenues comprise a significant share of government revenue), although the appropriate macro response during this episode is made more complicated by the wider economic crisis caused by the coronavirus pandemic, which has encouraged EM countries to pursue countercyclical policies (as many did during the GFC), loosening their policy stance (monetary and fiscal) to increase health spending and support demand. Some countries here have already announced policy adjustments, and amended their budget, such as Kazakhstan and Nigeria. Indeed, Kazakhstan’s initial response was textbook as the central bank raised its policy rate on 10 March (although this was subsequently reversed on 2 April), devaluing the tenge, and reportedly looking at budget cuts early on. Reports suggests the government has revised the 2020 budget based on US$20/bbl oil, down from US$50-55. Nigeria also devalued its currency surprisingly quickly and announced plans for a 10% cut in its budget. Reports suggest it has also cut its budget oil production forecast from 2.1mn bpd to 1.7mn and lowered its budget oil price to US$30/bbl, down from US$57. However, some countries may have limited room for manoeuvre, or limited policy space, which makes it even harder for them to respond flexibly to shocks or to pursue further austerity measures.
  2. Currency adjustment. Countries with free floats or market-determined exchange rates may allow their currencies to weaken, acting as a shock absorber, although this may be accompanied by intervention to smooth the adjustment process. Countries with pegged or fixed exchange rates may choose to intervene (selling dollars) in order to maintain the exchange rate parity, although some may need to devalue to protect limited reserves. The policy decision to devalue or not will in part be influenced by the authorities’ views on whether the shock is temporary or more persistent, and the inflation pass through and balance sheet impact of devaluation (at the government, corporate and household level). Devaluation will also help the fiscal balance, in the short-term, by increasing oil revenues in local currency terms. Nigeria and Kazakhstan have both devalued their currencies.
  3. Capital controls (capital flow management measures). Countries may impose capital controls to limit capital outflows, in order to protect reserves, although this does not address the underlying cause and could damage their reputation as an investment destination in future.
  4. IMF financing. Countries may seek IMF help (some already have) either through its emergency financing facilities or through programme requests or modifications to existing programmes. Countries in our sample that have, or are said to be seeking, help from IMF emergency facilities include Ghana, Gabon, Nigeria and Ecuador (see our IMF emergency financing tracker). Colombia, meanwhile, is seeking to renew an IMF contingent credit line. However, the estimated size of emergency financing available (now up to 150% of quota) may not be enough relative to the current account impact from a loss of oil exports in some cases.
  5. Other multilateral or bilateral support. Countries may seek support from the World Bank, other multilateral agencies (regional development banks) or bilateral partners (donors). For instance, Nigeria is also reportedly seeking US$2.5bn from the World Bank and US$1bn from the AFDB. Meanwhile, continuing regional financial support for Bahrain may help it to mitigate the negative impact from lower oil prices; Bahrain secured a US$10bn support package from Saudi Arabia, Kuwait and the UAE in 2018.
  6. Using savings. Some countries have sizeable savings (eg in sovereign wealth funds – SWFs –  or other external deposits) that could augment official reserves and be drawn down to provide an additional liquidity cushion in the event of a BoP crisis. Notably in our sample this includes Kuwait (other foreign assets of US$590bn at end-2019 according to the IIF), Trinidad (about US$6bn in its Heritage and Stabilisation Fund in September 2019, according to the ministry of finance), and Kazakhstan (assets of US$60bn in the National Oil Fund in February 2020, according to the central bank), and to a lesser extent Oman (other foreign assets of US$23bn at end-2019 according to the IIF). However, the liquidity and convertability of such assets, and conditions under which these assets can be used, is usually unclear.
  7. Debt relief – official sector debt relief and/or bond restructuring. Low income oil exporters that are deemed eligible may seek flow relief (a payment standstill) from bilateral creditors under an IMF/World Bank proposal. Eligible countries for a bilateral standstill in our sample are Cameroon, Republic of Congo, Ghana, and Nigeria. Some countries may seek a standstill or restructuring of their international bonds, either in parallel with official sector initiatives or separate to them, although this may be seen as a last resort (or first resort by others). Ecuador recently announced a consent solicitation to seek to defer interest payments on its bonds until August, although this could be a prelude to a full restructuring.

Investment implications

The market reaction since the oil price slump in early March has been broadly consistent with our findings. We plot the projected current account impact relative to reserves (y-axis) against bond spreads (x-axis) – see Figure 2. This reveals a clear (positive) relationship between the two variables – the more vulnerable countries on our measure have higher spreads (country risk). However, we should caution that other factors will also affect spreads, including other economic and political fundamentals, and trading liquidity.

Countries above/right of the fitted trend line may be judged as cheap while countries below/left of the fitted line may be expensive. The chart suggests that potentially, Angola is expensive as might be Kuwait, Bahrain and Kazakhstan. However, the degree of vulnerability may be overstated in the case of Kuwait and Kazakhstan, given their high savings, and in the case of Bahrain, given its external donor support umbrella (although that is conditional on the support continuing); on an adjusted basis, the current account impact relative to savings for Kuwait would be -3% and for Kazakhstan -12%, which might instead imply they are cheap. Conversely, Ghana may be cheap (although there are other factors that might explain its high spread). 

Meanwhile, while the individual CEMAC-3 countries may be above the line, we caution that this understates their vulnerability at a wider regional level, which may put Cameroon at more risk given current prices (although Cameroon should be less badly hit than other members), and Gabon.
