Asian equities slid on Monday after U.S.-Iran peace talks collapsed in Islamabad and President Donald Trump announced a U.S. blockade of the Strait of Hormuz, sending crude oil surging back above $100 a barrel and reigniting fears of a prolonged energy crisis across the region.
Japan’s Nikkei 225 fell 0.74%, South Korea’s KOSPI dropped 0.86%, and Hong Kong’s Hang Seng Index lost 0.9% — while mainland China’s CSI 300 bucked the trend with a modest 0.2% gain. Oil benchmarks Brent and WTI both jumped more than 7%, reversing much of the decline triggered by the short-lived ceasefire announced on April 7.

What Happened: U.S.-Iran Talks Collapse, Hormuz Blockade Announced
Weekend talks between the U.S. and Iran in Islamabad ended without agreement, dashing market hopes for a diplomatic resolution to the conflict. Trump declared on social media that American forces would block the Strait of Hormuz, adding that Iran would be “blown to hell” if it struck back. Iran’s top negotiator Mohammad Baqer Qalibaf pledged to fight back (Source: SCMP, April 13).
U.S. Central Command confirmed it would begin implementing a blockade of all maritime traffic entering and leaving Iranian ports, while stating that freedom of navigation for vessels transiting the Strait of Hormuz to and from non-Iranian ports would not be impeded (Source: Nikkei Asia, April 13).
“The failure to reach a deal is negative for markets because it reverses some of the peace dividend that had started to get priced in,” said Charu Chanana, chief investment strategist at Saxo Markets. “At the same time, the fact that talks happened at all means this is not automatically back to the most extreme oil panic seen earlier in this cycle.” (Source: SCMP)
Japan: Nikkei Slips 0.7%, JGB Yields Hit 29-Year High
Japanese stocks fell as oil prices surged, stoking inflation fears and reinforcing expectations of a Bank of Japan rate hike. The Nikkei 225 lost 0.74% to close at 56,502.77, down 421 points, amid heavy selling in energy-sensitive sectors.
The more critical development: 10-year Japanese government bond (JGB) yields surged to 2.49% — the highest level in 29 years. The surge was driven by concerns that persistent high oil prices would push Japanese inflation well above the BOJ’s target, forcing the central bank to act at its April 28 policy meeting. Financial markets are pricing in roughly a 60% chance of a rate hike (Source: Nikkei Asia, April 13).
Economic Minister Akazawa noted that BOJ policy to boost the yen could be “one option” to curb inflation, saying the central bank’s 2% target is “quite close” (Source: Nikkei Asia, April 12).
Meanwhile, Japan’s corporate bankruptcies hit a 12-year high as smaller companies struggle with rising prices and labor costs — underscoring the stagflationary pressures building across the economy (Source: Nikkei Asia, April 9).
South Korea: KOSPI Falls 0.86% on Foreign Selling, Won Weakens
The KOSPI opened sharply lower, plunging 121.59 points (−2.08%) to 5,737.28 at the bell — the steepest opening decline in weeks — before recovering through the session to close at 5,808.62, down 50.25 points (−0.86%) (Source: Yonhap, April 13).
The recovery from the opening rout was notable: the KOSPI clawed back more than half its losses by the close, suggesting that institutional investors were buying on dips while foreign investors were net sellers.
The South Korean won weakened against the U.S. dollar amid heightened geopolitical uncertainty. The won’s weakness adds pressure on import-dependent sectors and could further complicate the Bank of Korea’s policy stance after it held rates steady last week, as the Iran war fans inflation (Source: Yonhap, April 13; Nikkei Asia, April 10).
Key Korean stocks to watch: Samsung Electronics (005930.KS) and SK Hynix (000660.KS) face dual headwinds from the stronger dollar and rising energy costs, though their semiconductor supply chain dominance continues to provide structural support. Tracking South Korea’s export data remains critical for gauging demand in the AI semiconductor cycle.
China: CSI 300 Bucks the Trend, EV Stocks Rally
Mainland Chinese markets stood out as the lone bright spot. The CSI 300 gained 0.2%, while the ChiNext board surged 0.8% after the China Securities Regulatory Commission (CSRC) announced on Friday that it would loosen fundraising restrictions by allowing pre-profit companies to sell IPO shares on the market (Source: SCMP, April 13).
However, Hong Kong’s Hang Seng Index fell 0.9% to 25,660.85, dragged down by tech heavyweights: Tencent lost 2.9% to HK$490, and Alibaba slipped 1.8% to HK$123.20. Gold retailer Laopu Gold dropped 4% to HK$628.
Chinese EV Stocks: A Standout Sector
Chinese electric vehicle (EV) stocks rallied sharply against the falling broader market, powered by strong export data and the logic that rising oil prices accelerate EV adoption globally:
| Company | HK Close (HK$) | Change |
|---|---|---|
| Nio | 52.40 | +7.5% |
| BYD | 110.30 | +5.0% |
| Leapmotor | 55.85 | +1.6% |
| Xpeng | 67.60 | +0.9% |
China exported 2.23 million vehicles in Q1 2026, up 56.7% year-over-year—with new-energy vehicle (NEV) exports more than doubling to 954,000 units. As the Auto China show in Beijing approaches (April 24–May 3), new model launches with advanced self-driving and battery technology are expected to further boost the sector (Source: SCMP, April 13).
“Higher oil prices could trigger a non-linear increase in demand for new-energy vehicles once they pass consumers’ cost threshold,” said Dai Wenjie, analyst at Shenwan Hongyuan Securities. (Source: SCMP)
Key data this week: China’s Q1 GDP data is due Thursday, with economists expecting growth of approximately 4.8% — within the official 4.5–5% annual target.
Oil & Commodities: Brent and WTI Surge 7%+, Gold Down
| Asset | Level | Change |
|---|---|---|
| Brent Crude | Above $100/bbl | +7%+ ▲ |
| WTI Crude | Above $100/bbl | +7%+ ▲ |
| US Dollar Index | ~100 | +0.2% |
| Gold | ~$4,760/oz | −0.9% |
| Japan 10Y JGB Yield | 2.49% | 29-year high |

Crude oil surging back above the psychologically key $100 level reignites stagflation fears across Asia. Energy-import-dependent economies — Japan, South Korea, India, and Southeast Asia — are particularly vulnerable.
Gold’s 0.9% decline to around $4,760/oz may seem counterintuitive during a geopolitical crisis, but it reflects rising unease about monetary tightening by global central banks. If crude prices persist at these levels, central banks may be forced to raise rates to fight imported inflation — which is negative for gold as it raises the opportunity cost of holding non-yielding assets.
Saudi Aramco’s May premium for Asian oil shipments is the highest in data going back to February 2010, at $19.50 per barrel above the benchmark — locking in elevated costs for Asian refiners and consumers (Source: Nikkei Asia, April 8).
Analyst Outlook: “Fragile Middle Ground”
Despite the sell-off, the magnitude of Monday’s declines was milder than many anticipated. Markets appear to still price in a diplomatic path to resolve U.S.-Iran tensions, with the Hormuz blockade potentially used as leverage by Trump when negotiations eventually resume.
“We expect renewed pressure on risk assets and upward moves in oil early this week. However, gradual improvement in conditions is more likely than not before the end of April,” said Benjamin Jones, global head of research at Invesco. “We accept that there has been a de-escalation in the armed conflict but the scale of the de-escalation and lack of clarity on when trade flows will resume leaves us broadly still in the same place from an economic perspective.” (Source: SCMP)
Key Events to Watch This Week
- China Q1 GDP (Thursday): Economists expect ~4.8% growth, within the 4.5–5% annual target
- BOJ April 28 Policy Meeting: Markets pricing 60% chance of a rate hike amid surging inflation
- U.S.-Iran Diplomatic Developments: Any resumption of talks could trigger a rapid reversal in oil and equity markets
- Saudi Aramco May Pricing: Record $19.50/bbl premium already locked in for Asian buyers
- Auto China 2026 (April 24–May 3): New EV model launches from BYD, Nio, Xpeng expected
The Bottom Line
Monday’s session showed a market caught between two forces: the fear of a prolonged energy crisis if the Hormuz blockade escalates, and the residual hope that diplomacy will ultimately prevail. The relatively contained sell-offs suggest investors aren’t yet panicking — but they’re not complacent, either.
The divergence between mainland China (up) and the rest of Asia (down) is notable. China’s relative insulation from direct Hormuz exposure, combined with a proactive regulatory stance on ChiNext listings and the structural EV export boom, gives its markets a defensive quality that other Asian markets lack.
For energy-import-heavy economies like Japan and South Korea, the path of oil prices over the next two weeks will determine whether this is a temporary setback or the beginning of a deeper correction. Watch the JGB yield curve and the South Korea export data for the earliest signals.
