Market Performance
Japanese equities extended their losing streak for a third consecutive session, with the Nikkei 225 falling 0.97% to close at 60,816 and the Topix declining 0.97% to 3,827. Technology shares led the downturn, with notable declines from Fujikura (-2.9%), SoftBank Group (-2.7%), and Advantest (-0.8%).
Chinese markets showed relative resilience despite weak economic data. The Shanghai Composite decreased 0.08% to close at 4,132 points on May 19, while declines were led by Sany Heavy Industry (-6.01%), Aluminum Corporation of China (-4.12%) and China Fortune (-3.67%). New home prices across 70 major cities fell 3.5% year-on-year in April 2026, while retail sales rose just 0.2% annually, the weakest pace since December 2022.

Oil Markets and Geopolitical Risk
Energy markets whipsawed as diplomatic signals from the Iran conflict evolved. Brent crude futures reversed earlier gains and fell more than 1% to around $108 a barrel after Iranian media reported the US had proposed a temporary waiver of oil sanctions pending a final agreement, with separate reports indicating Tehran may be willing to a long-term nuclear freeze. International benchmark Brent crude futures for July added 0.79% to trade at $110.12 per barrel, while US West Texas Intermediate futures for June advanced 1.17% to $106.65 per barrel.
The geopolitical situation remains highly uncertain, with the Strait of Hormuz still largely shut and the Trump administration continuing to blockade Iranian ports, while Trump posted that "For Iran, the Clock is Ticking". Over the weekend, energy infrastructure across the Persian Gulf was targeted, including a nuclear facility in the United Arab Emirates, further heightening concerns over regional stability.
US-China Relations: From Trade War to Fragile Détente
The Trump-Xi summit in Beijing last week marked a pivotal moment in bilateral relations, though concrete outcomes remained limited. President Trump's hefty tariffs on China sparked a tit-for-tat trade war with Beijing, leading the two countries to briefly jack up tariffs on each other's goods to over 100%, but tensions have calmed since then, with both countries scaling back tariffs and China agreeing to halt export restrictions on rare earths.
On May 12, both countries reached a truce in a bid to reduce tensions, with the US reducing tariffs on Chinese goods to 30% while China responded by reducing tariffs on US products to 10%. In June 2025, the White House announced the trade deal with China was "done," with baseline tariffs sustained at 10% by China and 30% by the US, with the US agreeing to resume accepting Chinese students and China agreeing to resume shipments of rare earths.
Analysts suggest the summit could mark a reset in ties between the world's top two economies, with the two leaders expected to discuss Chinese purchases of American agricultural and industrial goods, tariffs, Taiwan, and rare earths, with the backdrop of the war in Iran. The US and China agreed to forge more cooperative ties on the first day of summit, striving to build a "constructive China-U.S. relationship of strategic stability".
However, Wall Street's major indices closed lower on Friday, weighed down by losses in technology stocks and a rise in US Treasury yields after the summit ended without major policy breakthroughs, leaving traders worried.
Central Bank Dynamics
Asian monetary authorities face a challenging environment as elevated oil prices threaten to reignite inflationary pressures. "Higher oil for longer will translate into a more hawkish bias" among central banks in Asia, according to JPMorgan Asset Management.
India's inflation has been low at around 2%, a 47-year low and the bottom end of the Reserve Bank of India's mandate, which gave room for the central bank to cut rates by 125bps from 6.50% to 5.25%. The Reserve Bank of India revised its full-year 2026 forecast lower from 3.1% to 2.6%, with rate cuts in 2026 a distinct possibility, especially if India can't improve tariff terms with the US.
In Japan, continued inflation of around 2% combined with GDP growth above potential will underpin the Bank of Japan's policy rate hikes, with the base case projecting the policy rate reaching 1.0% by the end of 2026.
China's central bank remains cautious. The People's Bank of China will likely retain a fine-tuning approach to balance growth and inflation objectives with banking sector profitability, with no meaningful policy rate cuts expected. The PBoC is expected to remain on an easing trajectory next year, looking for 20bp of rate cuts and 100bp of reserve requirement ratio cuts.
Semiconductor Supply Chain Developments
Taiwan's semiconductor sector continues to demonstrate strategic importance despite regional tensions. TSMC's first quarter 2026 consolidated revenue was NT$1,134.10 billion with net income of NT$572.48 billion and diluted earnings per share of NT$22.08. TSMC announced revenue for April 2026 was approximately NT$410.73 billion, a decrease of 1.1% from March 2026 but an increase of 17.5% from April 2025, with revenue for January through April 2026 totaling NT$1,544.83 billion, an increase of 29.9% compared to the same period in 2025.
TSMC's Board approved capital appropriations of approximately US$31,284.30 million for advanced technology capacity installation and fab construction, and approved capital injection of not more than US$20 billion to TSMC Arizona. Sony Semiconductor Solutions and TSMC signed a non-binding memorandum of understanding to form a strategic partnership for development and manufacturing of next-generation image sensors, with plans to establish a joint venture with Sony being the majority and controlling shareholder.
Currency Markets
The strongest currency in Asia is the Singapore Dollar (SGD), which is considered a financial hub and the most stable currency in Asia, followed by the Japanese Yen (JPY) and the South Korean Won (KRW). Latest REER estimates (as of September 2025) suggest that the Chinese yuan, Korean won, Indian rupee, Japanese yen and Indonesian rupiah have the most room to appreciate.
Foreign institutional investor flows recently point towards renewed foreign investor interest in Asia, particularly in Indian and Korean debt, supporting local currency appreciation. In 2026, inflation is unlikely to rise above central bank targets in any of the Asian economies under coverage, with rate cuts expected in Korea, India, Indonesia, the Philippines, and China.

FAQ
Q: What caused Asian markets to decline on May 19, 2026? A: Asia-Pacific markets fell Monday as investors weighed renewed geopolitical tensions after President Trump warned Iran to "get moving, FAST," raising fears of further escalation in the Middle East and potential disruptions to global oil supplies. Additionally, the Trump-Xi summit ended without major breakthroughs, disappointing investors who had hoped for more concrete trade progress.
Q: What is the current status of US-China trade relations? A: After reaching a truce in May 2025, the US reduced tariffs on Chinese goods to 30% while China responded by reducing tariffs on US products to 10%, with baseline tariffs sustained through a June 2025 deal. The US and China agreed at the recent Beijing summit to forge more cooperative ties and build a "constructive China-U.S. relationship of strategic stability", though concrete implementation details remain limited.
Q: How are central banks responding to elevated oil prices? A: Asian central banks are expected to move to higher interest rates, with "higher oil for longer" translating into a more hawkish bias among central banks in Asia, according to JPMorgan Asset Management. However, individual policies vary: India has already cut rates by 125 bps due to low inflation, while Japan is gradually hiking toward 1.0% by year-end, and China remains cautiously accommodative with modest easing expected.
