Nikkei Hits All-Time High, KOSPI Surges as TSMC Record Earnings and China GDP Beat Fuel Asia Rally

April 16, 2026 — ECONPLEX Economy News

Asia-Pacific markets surged on Thursday as the global rally extended into a tenth consecutive day, powered by record-breaking earnings from TSMC, a beat on China’s Q1 GDP, and growing conviction that the Iran war is nearing its end. Japan’s Nikkei 225 hit a fresh all-time high, South Korea’s KOSPI jumped over 2%, and the MSCI All-Country World Index marked a new record. The optimism was broad-based — but not universal. Australia bucked the trend on hawkish labor data, while oil prices dipped as ceasefire expectations deepened.

Why Today’s Session Mattered

Thursday’s Asian session was the moment the post-war rally went from recovery to record territory. MSCI’s All-Country World Index advanced 0.2% to notch a 10th straight day of gains and a fresh all-time high, while MSCI’s broadest gauge of Asia-Pacific shares ex-Japan rose 1.2%. “Hopes are high that a U.S.-Iran deal may be struck over the coming days,” DBS analysts wrote. “The Middle East conflict is no longer treated as a stress point by market participants, and we wonder if a U.S.-Iran deal or ceasefire extension is already in the price.” (Reuters via Investing.com)

The KOSPI surged 2.21% to 6,226.05, driven by Samsung Electronics (+3.08%) riding the wave of TSMC’s blockbuster Q1 earnings, which confirmed that AI chip demand remains “extremely robust.” The broader semiconductor rally lifted the Korean benchmark as investors bet that the AI supply chain boom — which has been the single most resilient sector through the Iran war disruptions — will continue to deliver outsized earnings growth.

Index	Close	Change
TAIEX	37,132.02	+1.12%

TSMC, the world’s largest contract chipmaker and Asia’s most valuable tech company, posted a 58% jump in Q1 net profit to a record T$572.5 billion ($18.2 billion), comfortably beating expectations. Revenue hit T$1.134 trillion ($35 billion), marking a fourth consecutive quarterly record. (CNBC)

CEO C.C. Wei raised TSMC’s full-year revenue growth forecast to “more than 30%” (up from “close to 30%”) and said capital expenditure would be at the high end of the $52–56 billion range. “AI-related demand continues to be extremely robust,” Wei said. Advanced chips under 7nm now account for 74% of total wafer revenue, with 3nm alone comprising 25%. (Reuters via Investing.com)

Counterpoint Research analyst William Li told CNBC that demand “has pushed TSMC’s manufacturing capacity to its limits” and the “sold-out environment” will remain throughout 2026. TSMC’s Taipei-listed shares have gained 35% year-to-date and closed at a record T$2,085 ahead of the report. (CNBC)

Capital Economics noted the data “will reinforce the RBA’s assessment that upside risks to inflation are greater than downside risks to the labour market” — dampening rate-cut expectations. A refinery fire also raised supply concerns in the energy sector. (Reuters via Investing.com)

Trump Threatens to Fire Fed Chair Powell

In a development that rattled the bond market, President Trump threatened to fire Fed Chair Jerome Powell from his separate seat on the Board of Governors if Powell does not vacate that post when his term as Fed chief ends on May 15. The standoff has renewed concerns about Federal Reserve independence at a time when markets are already navigating the intersection of war-driven energy inflation and potential easing.

What to Watch Next

• Iran ceasefire deadline — AP reports an “in principle” extension agreement ahead of the April 21 expiry, but the U.S. has not formally confirmed. Any collapse would reverse risk-on trades quickly
• TSMC aftershock — TSMC’s U.S.-listed ADRs were down 1.3% pre-market despite the earnings beat; markets may be “buying the rumor, selling the news” on AI chips. Watch how global semiconductor ETFs react
• China follow-through — Q1 GDP beat expectations, but Coface warns the export engine “could still be constrained.” Watch for further policy signals from Beijing
• Fed independence — Trump’s threat to oust Powell from the Board intensifies an already complex transition. Any escalation could move Treasury yields and the dollar sharply
• U.S. data — Weekly jobless claims and March industrial production are due today
• Earnings parade — PepsiCo, Abbott Labs, Travelers, U.S. Bancorp, and Charles Schwab all report before the U.S. open

The Bottom Line

Asia’s session was a masterclass in the two forces driving global markets right now: AI and geopolitics. TSMC’s record quarter confirmed that the AI chip cycle remains on an exponential trajectory, while ceasefire hopes have turned the Iran war from a stress point into a potential catalyst. The risk? DBS analysts are right to ask whether peace is already priced in. If the April 21 ceasefire deadline passes without an extension — or if Trump’s standoff with the Fed escalates — this rally’s momentum could reverse as fast as it built.
