Korea economic outlook and the macroeconomic implications of the technology boom Report Interpretation

Overview

JPMorgan argues that Korea has moved into a technology-led upswing. AI-related demand is lifting semiconductor exports, corporate profits, investment, fiscal revenue and the current account, although the transmission to consumption remains gradual and construction remains weak.

Core views

JPMorgan expects Korea's real GDP growth to accelerate from 1.1% in 2025 to 3.8% in 2026 and 3.3% in 2027. The report attributes the expansion primarily to the AI-related technology cycle, which is increasing exports, corporate profitability and, with a lag, facility investment. Net exports are expected to make a strongly positive contribution as the technology cycle offsets the drag from the Middle East conflict. Consumption and equipment investment should lead the domestic recovery, while construction is still expected to subtract from growth in 2026, albeit less severely than in 2025. The institution estimates potential growth at about 2.2-2.3%, up from its prior estimate below 2%, but expects the output gap to become positive in the second half of 2026 and widen through 2027. The external-sector outlook is central to the thesis. Real exports are projected to grow around 11% in 2026, supported by both technology export prices and volumes; non-technology export volumes have also recovered more strongly than expected despite oil-related disruption. Korea's AI-related technology exports, particularly semiconductors and computers, have lagged Taiwan since 2023 because of Korea's larger legacy-product exposure, but JPMorgan sees upside over coming quarters as Korea follows with a delay. Unlike prior cycles, rising semiconductor supply is occurring alongside rising prices because demand is expanding rapidly. Persistent AI demand, supply bottlenecks and large investment plans lead the report to argue that the sector may be operating around a higher nominal equilibrium. The boom also drives unusually strong nominal-income and terms-of-trade outcomes. JPMorgan forecasts nominal GDP growth of 21.3% year on year in 2026 and 10.4% in 2027, with the 2026 pace potentially the strongest since 1990-91. This differs from the earlier episode because the current rise is principally driven by export prices and terms-of-trade gains rather than broad domestic inflation. Export-deflator inflation reached 56.5% year on year in 2Q26 and is expected to moderate but remain elevated. Nominal GNDI expanded at 52.8% quarter on quarter annualized and 40.7% in consecutive quarters, largely through corporate profits; employee compensation has also accelerated. The report expects a greater eventual pass-through of profit gains into compensation and household income. Consumption is recovering, but less forcefully than JPMorgan's income-and-wealth-effect model had predicted for late 2025 and early 2026. The institution therefore expects private consumption to run at roughly a mid-2% annualized pace near term and firm over time, rather than surge immediately. Durable-goods demand is recovering after the drag from higher interest rates, while services and non-durables are broadly stable. Luxury demand has strengthened, but consumer staples appear weaker, consistent with a K-shaped pattern. The report judges the aggregate wealth effect modest: households' equity share increased only from 7% to 9% despite the 2025 market rally, real estate remains dominant, and equity ownership is concentrated in wealthier households with lower marginal propensity to consume. Inflation is framed as a mix of supply shocks and still-firm underlying pressures. Fuel-price volatility has affected headline CPI, but wholesale price caps distribute the burden among refiners, consumers and the government, limiting direct retail-fuel pass-through. JPMorgan expects inflation to rise into the mid-3% range in August on base effects before easing toward the high-2% range by 1Q next year. Core inflation should remain firmer than a benign disinflation narrative implies because terms-of-trade gains and income spill over into demand, including technology-related durables. However, easing labor-market tightness limits the upside: the report expects core inflation to undershoot the pace implied by a significantly positive output gap, as labor tightness has softened since 2023. Monetary policy has shifted from an easing mindset toward tightening as growth has proved more durable. JPMorgan targets a 3.75% terminal policy rate by 2Q27 and identifies upside risk, particularly if potential growth and the neutral rate are reassessed upward; it estimates potential growth could rise by around 50bp following the AI boom. Its Taylor-rule and financial-conditions analysis suggests a faster policy shift is becoming likely, though it stresses that policy is not mechanically tied to that rule and that uneven growth composition keeps the terminal-rate debate open. The technology profit windfall has major fiscal implications. Corporate-income-tax receipts are expected to rise sharply from 2H26, lifting fiscal revenue from 22.6% of GDP in 2025 to 23.0% in 2026 and 25.6% in 2027. The headline fiscal balance is forecast to move from a 1.7% of GDP deficit in 2025 to a 0.9% surplus in 2026 and a 3.8% surplus in 2027. The government plans a Future Response Fund to separate windfall revenue from structural revenue, limiting procyclical spending and avoiding excessively rapid debt reduction while retaining scope for targeted investment and redistribution. JPMorgan forecasts a historically large external surplus: the current account is projected at US$435 billion, or 19.0% of GDP, in 2026 and US$457 billion, or 16.7% of GDP, in 2027. The merchandise surplus and terms-of-trade gains more than offset the oil-shock drag, increasing private saving and net foreign assets. Currency effects are less direct, however, because net FDI and equity outflows plus overseas institutional investment recycle much of the surplus abroad. The adjusted basic balance is expected to improve from about -1.3% of GDP in 2025 to around 8% in 2026, supporting real effective exchange-rate appreciation in 2026-27, but the report expects the effect of the record current-account surplus on the REER to be more muted than historical relationships imply.

Analysis framework

JPMorgan links the AI-related technology cycle to export prices and volumes, corporate profits, investment, household income, inflation, monetary policy, fiscal revenue and external balances. It compares current conditions with prior cycles, uses growth and inflation forecasts, an output-gap and labor-market assessment, a simple Taylor-rule reference, and an adjusted basic-balance measure for foreign-exchange pressure.

Methodology notes

• Industry AnalysisSupply-demand framework

  Technology export prices and volumes are assessed against AI demand, supply bottlenecks and investment plans.

  The report explains the semiconductor upturn through simultaneous growth in supply, prices and AI-driven demand, rather than treating it as a conventional supply-led price decline cycle.

• MacroeconomicsTaylor rule

  A simple Taylor rule based on the output gap and core-inflation deviation from 2%.

  JPMorgan uses the rule as a reference point for how growth, inflation and financial conditions may support a faster monetary-policy shift, while noting that policy is not mechanically determined by it.

• Macroeconomics

  Adjusted basic balance: current-account surplus less net FDI outflows, net equity outflows and NPS overseas bond investments.

  The measure is used to judge longer-term foreign-exchange pressure after excluding major unhedged financial-account outflows.

Impact & implications

The report sees the technology boom broadening from exports and corporate profits into capital expenditure, fiscal receipts and eventually household income. It expects a stronger external buffer and some REER appreciation, but sustained capital outflows, weak construction and a potentially higher policy-rate peak moderate the transmission to domestic demand and currency adjustment.

Risks

• Construction-investment downside remains significant because housing starts are still nearly half below their peak.
• Oil-price disruption may weigh on trade and inflation, although technology strength is expected to offset much of the growth drag.
• The terminal policy rate carries upside risk if potential growth and the neutral rate are revised higher.
• Continued FDI, equity and institutional overseas outflows can mute the currency effect of the current-account surplus.

What to watch

• Whether AI-related semiconductor demand, prices and export volumes remain strong as Korea closes its lag versus Taiwan.
• The pass-through from corporate-profit gains into employee compensation and household consumption.
• Core inflation and labor-market tightness as the output gap turns positive.
• The Bank of Korea's policy shift and whether the terminal rate rises above 3.75%.
• Implementation and fiscal treatment of the proposed Future Response Fund.
• Capital outflows and the adjusted basic balance relative to the record current-account surplus.
