Falling oil prices ease pressure on Asian frontier economies, while Mongolia benefits from higher copper price forecasts

Overview

This edition of Asia Edge reassesses the macro outlook for Mongolia, Pakistan, Sri Lanka, and Vietnam after concerns over a prolonged closure of the Strait of Hormuz receded and JPMorgan's commodities team lowered its oil price forecasts. The report argues that growth forecasts overall do not need major adjustment, but lower oil prices will reduce peak inflation and import bill pressures, while improving the current account and fiscal outlook for some economies. At the same time, the Middle East situation remains unresolved, and fiscal subsidies, tax cuts, sticky core inflation, and exchange rate changes remain key uncertainties.

Core views

The core views are as follows: first, growth forecasts for the four countries are broadly unchanged because the base case already incorporated assumptions of a June Middle East ceasefire and a gradual reopening of the Strait of Hormuz. Second, inflation pressures are generally lower than previously feared, but transmission mechanisms differ across countries: Vietnam and Sri Lanka are supported by falling oil prices, Pakistan still faces double-digit inflation and sticky imported costs, and inflation in Mongolia is driven more by agricultural supply shocks such as meat. Third, monetary policy is more inclined toward staying on hold: JPMorgan withdraws its tightening calls for Pakistan and Sri Lanka and expects central banks to remain unchanged; the Bank of Mongolia is also likely to stay on hold. Fourth, on external accounts, Vietnam is dragged in the short term by a surge in tech goods imports, but its 2027 surplus forecast is revised sharply higher; deficit pressures in Pakistan and Sri Lanka have eased; and Mongolia's surplus remains strong, supported by copper prices and coal exports.

Analysis framework

The report uses a scenario reassessment approach, incorporating the new oil price baseline, fuel price pass-through, fiscal subsidies or tax cuts, exchange rate moves, import structure, commodity export prices, and IMF program constraints into country forecasts. The focus of the analysis is not to reprice equities, but to update the impact of macro variables on inflation, the current account, fiscal deficits, international reserves, and central bank policy.

Methodology notes

• Macro ForecastingOil Price Baseline Scenario Reassessment

  Re-transmit the lowered global oil price forecast into projections for inflation, import bills, and the current account.

  Lower oil prices usually ease fuel price and import bill pressures, but the actual impact depends on domestic fuel taxes, subsidies, exchange rates, and the pace of price pass-through.

• External Account AnalysisCurrent Account Decomposition

  Assess current account changes through dimensions such as energy imports, electronics and technology goods trade, and copper and coal exports.

  The report emphasizes that Vietnam's trade deficit mainly comes from a surge in electronics and technology imports, while Mongolia's external account improvement comes from higher copper price forecasts and strong coal exports.

• Monetary Policy AssessmentInflation Targeting and Central Bank Reaction Function

  Judge the probability of rate hikes or staying on hold based on peak inflation, core inflation, target ranges, and central bank communication.

  Rate hike expectations for Pakistan and Sri Lanka have been withdrawn, and the Bank of Mongolia also tends to keep the policy rate unchanged amid supply-driven inflation.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• Vietnam macro assets

  Affected jointly by falling oil prices and the technology trade cycle

  Strengths

  Lower fuel prices help contain inflation, the 2027 current account surplus forecast has been revised up significantly, and tech exports remain resilient.

  Weaknesses

  A record trade deficit appeared in the first five months of 2026, with electronics and technology goods imports up 49% year-on-year, leaving low visibility on the short-term external account.

  Comparison

  Compared with the energy shock, Vietnam is currently more affected by the technology goods import cycle.

  Risks

  A longer-than-expected period of elevated electronics imports, sticky core inflation, and fiscal pressure from extended tax support.

• Pakistan macro assets

  Relieved by lower oil prices but inflation remains elevated

  Strengths

  The current account deficit forecast has improved, international reserve estimates have been raised, and the IMF program continues to anchor fiscal targets.

  Weaknesses

  Inflation is still expected to remain double-digit by year-end and only return to the target range by end-2027, while real rates and policy credibility remain under pressure.

  Comparison

  Compared with Sri Lanka, Pakistan faces higher inflation pressure, and even if the central bank stays on hold, it still faces a stronger need for tightening.

  Risks

  Sticky imported costs, fiscal execution deviating from IMF targets, exchange rate pressure, and renewed rises in energy prices.

• Sri Lanka macro assets

  Inflation and policy assessment are jointly affected by falling oil prices and rupee depreciation

  Strengths

  Peak inflation has been revised lower, the current account deficit forecast has improved, and pressure for central bank rate hikes has eased.

  Weaknesses

  The rupee depreciated about 11% year-on-year in May-June, fuel price pass-through may lag, and the path for subsidy withdrawal remains uncertain.

  Comparison

  Compared with Pakistan, Sri Lanka has lower inflation, giving stronger justification for policy to remain unchanged.

  Risks

  Further currency weakness, price increases triggered by subsidy withdrawal, and tourism and the global backdrop being weaker than expected.

• Mongolia macro assets

  Driven jointly by higher copper price forecasts, coal exports, and supply-side inflation

  Strengths

  Higher copper price forecasts extend the cycle of mining revenue and current account surpluses, the fiscal deficit forecast has improved, and the threshold for the central bank to keep rates unchanged is relatively high.

  Weaknesses

  Inflation remains in double digits, with recent pressure coming mainly from meat and agricultural supply shocks, while the pass-through from lower oil prices is weak.

  Comparison

  Compared with energy importers, Mongolia has lower exposure to Middle East energy shocks, but is more sensitive to copper prices and Chinese demand.

  Risks

  Persistently accelerating core inflation, declines in copper prices or coal demand, and tax cuts weakening fiscal improvement.

Key data

• Vietnam 2026 average CPI forecast4.6%The previous forecast was 5.3%; the downgrade mainly reflects the base effect of lower oil prices.
• Vietnam 2027 average CPI forecast3.7%The previous forecast was 4.2%; core inflation is expected to approach 5% in summer, then gradually fall to around 3.2% by end-2027.
• Vietnam 2026 current account surplus forecast1.7% of GDPPreviously 1.8%, due to short-term trade pressure from a surge in tech goods imports.
• Vietnam 2027 current account surplus forecast5.3% of GDPPreviously 2.6%, driven by lower oil and electronics imports and strong tech exports.
• Sri Lanka peak inflation forecast5.6%Previously 6.0%; expected to gradually fall below 5% around mid-2027.
• Sri Lanka 2026 current account forecast0.2% of GDP deficitPreviously a 0.4% deficit, due to a lower import bill.
• Pakistan peak inflation forecast13.4%Expected to peak in July, versus the previous forecast of 14.2% in August; inflation is not expected to return to the SBP's 5%-7% target range until end-2027.
• Pakistan estimated international reserves in June 2027US$20.9bnRaised by about US$1bn, reflecting eased pressure from energy imports.
• Mongolia 2026 CPI forecast9.1%Previously 9.4%; the impact of oil prices is limited, mainly because Mongolia sources more of its energy from Russia.
• Mongolia 2027 CPI forecast6.0%Previously 6.6%; the decline is more pronounced after agricultural supply pressures fade.
• Mongolia 2027 current account forecast2.4% of GDP surplusClose to the 2.7% surplus level in 2026, supported by higher copper price forecasts and coal shipments.
• Upward revisions to copper price forecasts for 2026H2 and 2027 in MongoliaUp 16% and 19%, respectivelyJPMorgan's commodities team believes US-China tensions and structural demand from electrification support copper prices.
• Mongolia fiscal deficit forecast0.8% of GDP in 2026, 1.0% of GDP in 2027Previously 1.5% and 1.6%, respectively, reflecting mining revenue above prior assumptions.

Impact & implications

For investment and macro allocation, falling oil prices reduce stagflation risks for some energy-importing Asian countries and support improvements in current accounts and international reserves; however, the degree of benefit varies across countries. Vietnam's short-term external pressure comes more from tech goods imports than from energy, Pakistan remains constrained by high inflation and IMF fiscal requirements, Sri Lanka's policy rate path is tilted more toward stability, and Mongolia benefits more directly from higher copper price forecasts and coal demand. Investors should distinguish between the broad relief brought by lower oil prices and each country's own structural factors.

Risks

• The Middle East situation is still not fully resolved, and oil prices may rise again.
• Adjustments to domestic fuel taxes, subsidies, and price stabilization funds may weaken the pass-through of lower oil prices to inflation.
• Sticky core inflation may force central banks to reconsider rate hikes.
• If Vietnam's surge in tech goods imports is not temporary, it will drag on current account improvement.
• Fiscal targets in Pakistan and Sri Lanka depend on IMF program execution, and policy slippage would increase risk.
• Mongolia's copper prices and coal exports are highly dependent on the global commodity cycle and Chinese demand.
• Currency depreciation may offset the cushioning effect of lower oil prices on imported inflation.

What to watch

• Progress on reopening the Strait of Hormuz and geopolitical risks in the Middle East.
• Subsequent changes in oil and copper price forecasts from JPMorgan's commodities team.
• Whether Vietnam's electronics and technology goods imports fall back to normal.
• Whether Pakistan's inflation peaks in July as expected, and SBP policy communication.
• Sri Lanka's fuel price adjustments, subsidy withdrawal, and rupee trends.
• Mongolia's August CPI and core inflation performance, as well as the September central bank meeting.
• Execution of fiscal targets for Pakistan and Sri Lanka under IMF programs.
• The final size and implementation timing of Mongolia's tax cut plan in parliament.
