Goldman Sachs: U.S.-Iran Thaw Drives Oil Prices Lower, Downgrades Energy, Upgrades Asia Pacific Banks
With the signing of a memorandum of understanding between the U.S. and Iran and expectations of the reopening of the Strait of Hormuz, Goldman Sachs lowered its Brent crude price forecast and downgraded the Asia Pacific energy sector rating from overwight to neutral; meanwhile, due to favorable interest rate environment and wealth effect, upgraded the bank sector (excluding China/Australia) to overweight.
- MXAPJ Index rebounded 3.9%, South Korea (+14%) and Taiwan (+5%) led gains, technology hardware and semiconductors performed well.
- U.S.-Iran situation eased, Strait of Hormuz expected to reopen gradually, Goldman Sachs lowered 2026Q4 Brent oil price forecast from $90 to $80.
- Energy sector earnings upside momentum peaked, rating downgraded from overweight to neutral.
- Bank sector benefited from wealth effect, active capital markets, and approx. 4% attractive dividend yield, rating upgraded from neutral to overweight (excluding China and Australia banks).
- MSCI upgraded South Korea's Investor Tools Availability from negative to positive, but maintained other five negative criteria, temporarily not including in developed market index.
- MSCI downgraded Indonesia's Information Flow standard from positive to negative, reflecting opaque ownership issues, but base case still maintains its emerging market status.
Report interpretation
Overview
This report primarily analyzes market performance and sector allocation strategies for Asia ex-Japan equities (MXAPJ) against the backdrop of easing geopolitical tensions (U.S.-Iran MOU signed) and ubiquitous hawkish stances by global central banks. Core conclusion: Erosion of geopolitical risk premium leads to downward revision in oil price expectations, prompting Goldman Sachs to downgrade energy sector rating to neutral; conversely, under expectations of sustained high or further tightening rates, bank sector gains upgrade to overweight due to net interest margin advantages, wealth effects, and revitalized capital market activity. Additionally, the report details MSCI's latest adjustments to classification standards for South Korea and Indonesia markets and potential impact on capital flows.
Core views
Geopolitical Easing and Oil Price Forecast Downgrade: With the signing of a memorandum of understanding between the U.S. and Iran, the market expects the Strait of Hormuz to gradually reopen, with Middle Eastern supply recovery earlier than expected. Accordingly, Goldman Sachs' oil analysts lowered their Q4 2026 Brent crude price forecast from $90/barrel to $80/barrel, and the 2027 average price forecast from $80/barrel to $75/barrel. While risks exist both ways, upward risk slightly dominates. This change directly weakens the logic for prior gains in energy stocks, causing the sector to lag recently. Major Sector Allocation Adjustment: Downgrade Energy, Upgrade Banks. Given the downward revision in oil price expectations and the peaking momentum in energy stock earnings upgrades, Goldman Sachs downgraded the Asia Pacific energy sector rating from overweight to neutral. At the same time, it upgraded the bank sector (including Japan, excluding China and Australian banks) from neutral to overweight. Supporting logic for bullishness on the bank sector includes wealth effects from stock gains, strong capital market activity, an attractive dividend yield of approx. 4%, and banks' historical positive sensitivity to rising rates. For Chinese banks, given defensive balance sheet strategies and weak credit growth, maintain neutral rating; Australian banks remain neutral due to tight capital. Market Performance and Capital Flows: The MXAPJ Index rebounded 3.9% this week, with South Korea (+14%), Taiwan (+5%), and Philippines (+5%) outperforming China offshore market (-3%) and Thailand (-2%). Technology hardware and semiconductors, capital goods sectors led gains, while internet/media and energy sectors lagged. On funds, emerging Asia markets excluding China recorded $5.7 billion net FII inflow, driven mainly by Taiwan (+$3.3 billion) and South Korea (+$1.7 billion). However, retail investors were net sellers in Taiwan and South Korea this week. MSCI Market Classification Updates: Regarding South Korea, MSCI upgraded Investor Tools Availability from negative to positive, reflecting progress in derivatives listed on KRX. However, the other five criteria (Foreign Exchange Liberalization, Investor Registration, Information Flow, Clearing and Settlement, Transferability) remain negative, so Goldman Sachs base case believes South Korea will not be included in Developed Market indices in the annual review on June 23. Regarding Indonesia, Information Flow standard was downgraded from positive to negative, mainly concerns regarding opaque ownership and coordinated trading limit investor ability to assess true float. Nevertheless, Goldman Sachs still expects Indonesia to retain its emerging market status, though Foreign Investment Limits (FIF) may be adjusted downwards based on new disclosures.
Analysis framework
Goldman Sachs' analysis follows the logic chain of Macro Event-Driven -> Asset Price Revaluation -> Industry Fundamentals Verification -> Allocation Recommendation Adjustment. First, capture the key macro variable of U.S.-Iran situation easing and derive its direct impact on oil supply and prices (downward oil price forecast). Second, combine Federal Reserve and Asian central banks' hawkish monetary policy stances to analyze differences in industry sensitivity to interest rates and commodity prices. By comparing earnings revision trends for energy stocks (dependent on high oil prices) and bank stocks (benefiting from high rates and wealth effects), found that energy stock earnings upward momentum weakened while bank stocks show improvement potential. Finally, combine structural capital flow expectations driven by MSCI index classification adjustments to comprehensively give overweight/underweight suggestions at regional and sector levels. This methodology emphasizes the timeliness and directionality of macro factor transmission to micro industry performance.
Methodology notes
Impact of Geopolitics on Commodity Supply
The report analyzes the impact of the U.S.-Iran agreement on Strait of Hormuz navigability to judge the pace of Middle East crude supply recovery, thereby adjusting oil price forecasts. This is a typical logic where geopolitical events influence commodity prices by changing supply expectations.
Transmission of Oil Price Changes to Energy Sector Earnings
Falling oil prices directly compress upstream energy enterprises' profit margins, leading to peaking profit expectations, thus triggering rating downgrades. This reflects the direct transmission mechanism of upstream resource price volatility to fundamental aspects of related listed companies.
Industry Comparison Based on Earnings Revision
The report looks not only at static valuation but also pays attention to dynamic profit prediction adjustment directions. Energy stock earnings upturn stagnation while bank stocks have potential for improvement; such marginal changes are important basis for adjusting sector allocation weights.
Impact of Central Bank Monetary Policy Stance on Asset Pricing
The report mentions Federal Reserve and multiple Asian central banks' hawkish stance (rate hikes or maintaining high rates) and points out that bank stocks usually perform well in rising interest rate environments. This implicitly contains logic using monetary policy cycles to judge relative returns of financial stocks.
Capital Flow Expectations Triggered by MSCI Index Adjustments
Minor adjustments by MSCI on South Korea and Indonesia market access standards, although they do not immediately change index belonging, affect international institutional investors' expectations on liquidity improvement and risk premium, thereby guiding capital flows.

Impact & implications
For investors, this means reducing exposure to energy stocks linked to oil prices in Asia Pacific equity allocation, and increasing allocation to bank stocks, especially those benefiting from high interest rate environment and active capital markets (such as Japanese and some Southeast Asian banks). Progress in South Korea's structural reform reforms, although not making it immediately enter developed market index, improvements in investor tools availability may bring long-term liquidity premium. Indonesia's ownership transparency issues formally marked as negative, reminding investors to be alert to downward adjustment risks for its foreign investment limits. Overall, market style may shift from previous resource-driven to finance and technology hardware-driven.
Risks

- Global central bank rate hikes exceed expectations, triggering economic hard landing
- MSCI makes more negative adjustments to South Korea or Indonesia market classification than expected
