BOJ|JPYUSD/JPY has moved sharply to 159.50 (down 2.33%), a significant yen strengthening move heading into the BOJ decision at 11:30 JST. The prior overnight session had USD/JPY at approximately 163.50 per research notes, and Mitsubishi UFJ had flagged potential tests of 165 with intervention risks — the current pullback to 159.50 may reflect pre-BOJ positioning. Tokyo Core CPI for July (due 08:30 JST, forecast: 1.8% y/y vs prior 1.6%) will set the inflation context for the BOJ's statement.

NIKKEI|SEMISJapanese semiconductor and electronic components stocks bore the brunt of Thursday's Nikkei 225 decline: SCREEN Holdings (7735.T) -17.25%, KIOXIA Holdings (285A.T) -13.85%, Murata Manufacturing (6981.T) -12.89%, Taiyo Yuden (6976.T) -12.36% and Tokyo Electron (8035.T) -10.59%. The TOPIX IT & Services sub-index fell 1.22% and the Nikkei VIX remains elevated at 39.52 (down only 3.94%), indicating persistent near-term volatility expectations in Japanese equities.

TOPIX|AUTOSTOPIX Electrical Equipment was the standout sector gainer on Thursday (+2.52%), and Toyota Motor (7203.T) surged 7.18% — likely supported by yen weakness in the prior session (USD/JPY was near 163.50 overnight) which benefits Japanese exporters' earnings translation. Komatsu (6301.T) also gained 7.63%, reflecting both yen dynamics and copper's 3.71% rise to $6.506/lb supporting construction equipment demand signals. The TOPIX Autos & Transport sub-index fell 2.21%, however, indicating the gains were not uniform across the sector.

KOSPI|TWSEThe KOSPI's 5.98% decline to 5,663.24 and TWSE's 3.76% fall to 40,039.18 represent the two sharpest regional equity drawdowns on Thursday, both reflecting heavy semiconductor and technology export exposure. USD/KRW moved to 1,421.14 (down 1.47%, i.e. KRW strengthening), and TWSE at 40,039.18 remains sharply elevated year-to-date in absolute terms but the single-session loss signals meaningful risk repricing in the semiconductor supply chain.

CHINA|SSE|STARChina's STAR 50 index fell 5.38% to 1,588.41 in the prior session, with technology, semiconductor and aviation equipment names leading losses amid a domestic deleveraging cycle and US semiconductor sector weakness spillover. Despite RMB 2.34 trillion in two-market turnover, Northbound flows were selective, concentrating in consumer staples and appliance names (Luzhou Laojiao, Midea, Yili) rather than tech, highlighting a bifurcation between foreign institutional preferences and domestic sector momentum.

GOLD|MATERIALS|ASXGold surged 3.43% to $4,173.20/oz — a record high per available data — driven by safe-haven demand from both Fed policy uncertainty and Middle East escalation. Copper gained 3.71% to $6.506/lb and platinum rose 5.09% to $1,671/oz, while palladium added 5.96% to $1,320/oz. On the ASX, the Materials sector gained 1.12% and Health Care led all sectors at +4.24%, while the ASX VIX ticked up 2.06% to 11.39, a relatively contained volatility reading compared with the Nikkei VIX at 39.52.

Asia Sectors to Watch

Sector Outlook · Signal & Rationale

Energy

Middle East escalation (Iran missile strike on US base in Jordan, US-Saudi retaliatory strikes in Iraq) drove an intraday surge in Brent crude, with the risk premium still embedded in prices at $89.28/bbl, though Brent closed down 1.61% session-on-session per snapshot data.

▲ Positive bias

Financials

Long-end US yield steepening (30-year +11bp to 5.20%, 10-year +6bp to 4.67%) is structurally supportive for net interest margins, but TOPIX Banks fell 3.79% on Thursday and the BOJ rate decision today introduces near-term policy uncertainty for Japanese bank earnings.

● Neutral

Technology

US semiconductor sector weakness transmitted sharply to Asia-Pacific, with SCREEN Holdings (-17.25%), KIOXIA (-13.85%), Murata (-12.89%), Taiyo Yuden (-12.36%) and Tokyo Electron (-10.59%) all posting heavy losses in the Nikkei, while KOSPI and TWSE fell 5.98% and 3.76% respectively on concentrated semis exposure.

▼ Negative bias

Materials

Gold (+3.43% to $4,173.20/oz), copper (+3.71% to $6.506/lb), platinum (+5.09%) and palladium (+5.96%) all posted strong gains on safe-haven and industrial demand signals, supporting Australian and global materials names, though iron ore (-0.03% to $98.27/t) and coking coal (-1.80% to $218.50/t) were flat to lower.

▲ Positive bias

Healthcare

ASX Health Care was the top-performing ASX sector on Thursday, gaining 4.24%, in a move consistent with defensive rotation amid geopolitical risk-off and Fed policy uncertainty.

▲ Positive bias

REITs

Long-end US Treasury yields rising sharply — 30-year at 5.20% (+11bp) and 10-year at 4.67% (+6bp) — increases the discount rate applied to real estate cash flows, representing a structural headwind for listed REITs, with ASX REITs gaining only 0.75% despite the broader market's 1.01% advance.

Analysis

Macro Themes

Top 5 Structural Themes · Asia-Pacific Focus

Structural Driver

The Bank of Japan has shifted from ultra-loose policy to gradual normalization, with the short-term rate now at 1% amid reflation and wage pressures that mark a 31-year high. This creates a structural divergence from other major central banks, sustaining yen depreciation near multi-decade lows and boosting exporter competitiveness while pressuring importers through higher input costs. The mechanism directly links higher JGB yields to financial sector re-rating and currency-driven earnings bifurcation across the Nikkei.

Current Catalyst

BoJ’s July 30-31 meeting is expected to hold rates at 1% while revising FY2026 growth forecasts higher amid persistent inflation vigilance, following the July 29 close where autos and transport sectors rose 5.6%.

Watch

BoJ policy decision and growth forecast revisions on July 31

Names to Watch

7203.T Toyota Motor Corp +2.1% Wed · yen tailwind on exports

7267.T Honda Motor Co Ltd +1.8% Wed · direct yen beneficiary

8306.T Mitsubishi UFJ Financial +0.9% Wed · higher yield sensitivity

9983.T Fast Retailing Co Ltd -0.4% Wed · import cost pressure

Structural Driver

PBOC and fiscal authorities are pivoting toward consumption support and targeted liquidity easing to offset property sector drag and deflationary risks, with Q2 growth slowing to around 4.3%. This structural shift prioritizes high-value manufacturing and domestic demand while deploying RRR cuts and LPR adjustments under the 15th Five-Year Plan framework. The dynamic transmits through supply chains to Korean and Taiwanese exporters tied to China demand.

Current Catalyst

Expectations for PBOC RRR or OMO easing intensified after July 29 mixed regional performance, with China-sensitive names reflecting Q2 slowdown data and incremental fiscal measures.

Watch

PBOC liquidity operations and potential RRR announcement in early August

Names to Watch

700.HK Tencent Holdings Ltd +1.2% Wed · consumption support exposure

9988.HK Alibaba Group Holding Ltd +0.8% Wed · domestic demand focus

005930.KS Samsung Electronics Co Ltd +0.5% Wed · China export linkage

300750.SZ Contemporary Amperex Technology -0.3% Wed · EV supply chain sensitivity

Structural Driver

Global capex in AI infrastructure continues to drive sustained chip demand, reinforcing supply-chain resilience across foundries and memory producers despite cyclical inventory swings. This structural force elevates Korean and Taiwanese names as key beneficiaries of US Big Tech spending, with export data showing resilient EM semiconductor shipments. The cycle transmits directly into Japanese equipment suppliers via capex multipliers.

Current Catalyst

Meta and Microsoft earnings on July 29 highlighted ongoing AI spend, lifting related Asian semis after the July 29 close where electronic equipment lagged -1.4% amid broader rotation.

Watch

Amazon and Apple earnings on July 30 for AI capex signals

Names to Watch

005930.KS Samsung Electronics Co Ltd +0.5% Wed · memory AI exposure

000660.KS SK Hynix Inc +1.1% Wed · HBM demand strength

8035.T Tokyo Electron Ltd +2.4% Wed · equipment capex link

2454.TW MediaTek Inc +0.7% Wed · chip cycle beneficiary

Structural Driver

Yen weakness and domestic recovery trends are driving sector rotation into Japanese autos and transport alongside Australian consumer discretionary names, with autos benefiting from export competitiveness. This structural rotation reflects currency-driven earnings upgrades and commodity-linked consumer spending in Australia. Direct transmission occurs through Nikkei sector outperformance and ASX discretionary gains amid global risk appetite.

Current Catalyst

Nikkei autos and transport rose 5.6% on July 29 while ASX consumer discretionary gained 2.7%, coinciding with yen pressure near multi-decade lows ahead of the BoJ meeting.

Watch

Japan retail sales data and Australia consumer confidence on August 5-6

Names to Watch

7203.T Toyota Motor Corp +2.1% Wed · yen export boost

BHP.AX BHP Group Ltd -0.8% Wed · materials lag

3697.T Shift Inc +7.7% Wed · retail rotation play

WOW.AX Woolworths Group Ltd +1.4% Wed · discretionary strength

Structural Driver

US Fed policy path, energy price volatility and trade tensions interact to shape Asia-Pacific risk appetite and capital flows, with the July 29 hold at 3.50%-3.75% introducing hawkish undertones. This structural interplay elevates inflation expectations across the region while pressuring cyclicals and materials amid oil swings. Transmission occurs through broad beta exposure in exporters and commodity names.

Current Catalyst

Fed July 29 hold with dissent and oil volatility triggered post-decision equity weakness, with Nikkei mixed and ASX materials down 1.4% on July 29 amid geopolitical risks.

Watch

US July employment report and oil inventory data due August 1-5

Market News

Global Macro Overview

The dominant macro driver overnight was the FOMC's 9-3 vote to hold the federal funds rate at 3.50–3.75%, with three regional presidents — Hammack, Kashkari and Logan — dissenting in favour of a 25bp hike, marking the first three-way hawkish dissent split since 2016. The result was a 'hawkish pause' that steepened the US Treasury curve sharply: the 30-year yield closed at 5.20% (up 11bp) and the 10-year at 4.67% (up 6bp), while the 2-year eased 4bp to 4.22% — a configuration that prices in a non-trivial probability of further tightening and reflects the market's unease about inflation persistence alongside a geopolitical oil supply shock. Compounding the move, Middle East escalation — Iran's ballistic missile strike on a US base in Jordan and subsequent US-Saudi retaliatory strikes in Iraq — injected a material energy risk premium, with Brent crude settling at $89.28/bbl (down 1.61% at Thursday's close per snapshot data) after having surged intraday on the conflict news, while gold hit $4,173.20/oz (up 3.43%), a new high driven by safe-haven demand. The VIX collapsed 17.23% to 17.10 as US equities rallied — the S&P 500 gaining 1.66% to 7,437.63 and the NASDAQ surging 2.78% to 25,122.18 — suggesting US equities are pricing the pause as a policy ceiling rather than a prelude to hikes, even as the long end tells a different story. For Asia-Pacific markets, the cross-asset configuration is complex and bifurcated: USD/JPY has pulled back sharply to 159.50 (down 2.33%), which compresses yen-weakness tailwinds for Japanese exporters like Toyota (7203.T, +7.18% Thursday) and weighs on the Nikkei VIX still elevated at 39.52, while the BOJ rate decision due at 11:30 JST today is the single most critical near-term catalyst for the region. The KOSPI's 5.98% decline and TWSE's 3.76% drop reflect concentrated semiconductor and technology sector pressure transmitted from US semis weakness — visible in Thursday's Nikkei losers including SCREEN Holdings (7735.T, -17.25%), KIOXIA (285A.T, -13.85%), Murata Manufacturing (6981.T, -12.89%), and Tokyo Electron (8035.T, -10.59%) — while the CSI 300's 3.60% drop signals continued China A-share tech deleveraging, with cross-asset safe-haven flows concentrating in gold, copper (up 3.71% to $6.506/lb) and platinum (up 5.09% to $1,671/oz).

Market-Moving Events · Asia-Pacific

BOJ|JAPANThe Bank of Japan's two-day policy meeting (July 30-31) concludes today, with the rate decision due at 11:30 JST alongside the Monetary Policy Statement and Outlook Report, followed by Governor Ueda's press conference at 14:30 JST. Market consensus expects a hold at the current rate (prior: below 1.00%), but the tone of the statement and Outlook Report will be critical given USD/JPY's sharp move to 159.50 (down 2.33% on the day) and the Nikkei VIX remaining elevated at 39.52.

JAPAN|NIKKEIThe Nikkei 225 closed down 1.49% at 61,434.19 in Thursday's session, with a pronounced divergence between semiconductor/electronic components losers and industrial/auto gainers. SCREEN Holdings (7735.T) fell 17.25%, KIOXIA (285A.T) dropped 13.85%, Murata Manufacturing (6981.T) lost 12.89%, Taiyo Yuden (6976.T) fell 12.36% and Tokyo Electron (8035.T) declined 10.59%, all reflecting US semis sector pressure. On the upside, Konami (9766.T) surged 12.74%, Keyence (6861.T) gained 9.36%, Komatsu (6301.T) rose 7.63%, Toyota (7203.T) added 7.18% and Shiseido (4911.T) gained 7.01%.

CHINA|SSE|CSIChinese equities saw sharp divergence: the SSE Composite edged up 0.40% to 3,828.47 but the CSI 300 fell 3.60% to 4,529.10, reflecting concentrated selling in technology and semiconductor names on the STAR board, consistent with the prior session's STAR 50 decline of 5.38% to 1,588.41 and two-market turnover of RMB 2.34 trillion. Northbound flows showed selective buying in consumer names including Luzhou Laojiao, Midea and Yili despite the broader tech deleveraging.

KOREA|KOSPIThe KOSPI fell 5.98% to 5,663.24, one of the sharpest single-session declines in the region, reflecting concentrated exposure to semiconductors and technology given Korea's export structure. Foreign net buying contrasted with retail selling in the prior session, but the scale of Thursday's loss indicates the US semis sell-off and geopolitical risk-off combined to overwhelm inflows.

HKEX|SGXThe Hang Seng (HKEX) outperformed regional peers, gaining 1.96% to 25,807.92, while the Singapore STI (SGX) rose 1.73% to 5,713.19. The ASX 200 added 1.01% to 9,038.60, with Health Care (+4.24%), Consumer Discretionary (+2.37%) and Information Technology (+1.98%) leading sector gains, and Financials (+0.18%) the laggard.

Market-Moving Events · Americas

FEDThe FOMC voted 9-3 to hold the federal funds rate at 3.50–3.75% at its July 30 meeting, with Cleveland Fed's Hammack, Minneapolis Fed's Kashkari and Dallas Fed's Logan all dissenting in favour of a 25bp hike — the first three-dissenter hawkish split since 2016. The result has been characterised as a 'hawkish pause,' with the dissent composition signalling meaningful internal division over the inflation outlook.

MACROUS Treasury yields moved sharply at the long end following the FOMC outcome: the 30-year yield rose 11bp to close at 5.20% — briefly breaching that level intraday — and the 10-year climbed 6bp to 4.67%, while the 2-year eased 4bp to 4.22%, steepening the curve and reflecting market concern about fiscal supply and a potential further hike cycle.

ENERGY|GEOMiddle East escalation drove an intraday surge in crude oil: Iran launched ballistic missiles at a US base in Jordan, prompting US and Saudi retaliatory strikes on Iran-backed targets in Iraq, with President Trump stating the US would 'hit Iran hard.' Brent crude (September contract) surged as much as 8% intraday on the conflict news; the snapshot close shows Brent at $89.28/bbl (down 1.61% session-on-session), with WTI at $83.98/bbl (down 0.57%).

TECH|SEMISThe Philadelphia Semiconductor Index came under broad selling pressure, transmitting directly to Asia-Pacific semi names. The weakness reflected both the hawkish Fed backdrop and geopolitical risk-off rotation, with no specific single-stock US earnings details flagged in overnight coverage but the sector-level pressure clearly evidenced in Japan and Korea movers.

MACRODespite the hawkish-leaning FOMC outcome and geopolitical oil spike, US equities rallied sharply: the S&P 500 gained 1.66% to 7,437.63, the NASDAQ surged 2.78% to 25,122.18, and the Russell 2000 added 1.37% to 2,946.10. The VIX fell 17.23% to 17.10, suggesting broad equity markets interpreted the FOMC hold as a policy ceiling rather than a tightening signal, at least in the near term.

Market-Moving Events · Europe

MACROEuropean indices posted mixed results against the backdrop of elevated oil, a stronger USD following the FOMC hawkish pause and rising long-end US yields. The Euro Stoxx 50 gained 1.53% to 6,344.40 and the CAC 40 rose 0.92% to 8,485.64, while the DAX added a more modest 0.60% to 25,612.03 and the FTSE 100 edged down 0.10% to 10,897.27.

ENERGY|GEOThe Iran-US Middle East escalation — including the Iranian ballistic missile strike on a US base in Jordan and US-Saudi retaliatory strikes in Iraq — represents a direct energy supply risk for European markets given their LNG and crude import dependencies, with Brent crude having surged sharply intraday on the news before settling at $89.28/bbl.

ECBThe EU Core CPI Flash Estimate for July is due at 18:00 JST today (forecast: 2.4% y/y, unchanged from prior), alongside the headline CPI Flash Estimate (forecast: 2.9% y/y vs prior 2.8%). These prints will be closely watched for confirmation of whether ECB policy divergence from the now-hawkish-leaning Fed is widening, with implications for EUR/USD and European rate markets.

MACRONo major ECB or Bank of England policy announcements or single-stock European movers were flagged in overnight coverage. The primary European market driver remains the interplay between geopolitical oil risk, US yield curve steepening and the USD index move toward 100.92 per overnight reports.

Risks & Watch Items

Key Risks · Geopolitical · Supply Chain · Policy

BOJBOJ rate decision, Monetary Policy Statement and Outlook Report due at 11:30 JST today, followed by Governor Ueda's press conference at 14:30 JST — USD/JPY at 159.50 (down 2.33%) and Tokyo Core CPI forecast at 1.8% y/y (due 08:30 JST) will frame market interpretation of any hawkish language shift.

GEO|ENERGYMiddle East escalation remains active: Iran's ballistic missile strike on a US base in Jordan, US-Saudi retaliatory strikes in Iraq and President Trump's statement that the US will 'hit Iran hard' represent an ongoing supply-route and geopolitical risk premium in crude oil markets with Brent at $89.28/bbl.

MACRO|FEDThe first three-way hawkish dissent at the FOMC since 2016 (Hammack, Kashkari, Logan voting for a 25bp hike) has steepened the US curve — 30-year at 5.20%, 10-year at 4.67% — and US Employment Cost Index q/q (forecast: 0.8%, prior: 0.9%) due at 21:30 JST today will be watched for further evidence of wage inflation feeding the dissent narrative.

CHINA|SEMISChina's STAR 50 index fell 5.38% in the prior session amid domestic tech deleveraging and US semiconductor spillover, with the CSI 300 down 3.60% on Thursday — continuation of this deleverage cycle into Friday's session is a key watch given RMB 2.34 trillion turnover volumes and the divergence between Northbound selective buying and broad domestic selling.
