Japan election lift sparks Asian equity rally as Nikkei hits record high

Japanese equities led a broad Asian market surge on Monday after Prime Minister Sanae Takaichi’s ruling coalition won a decisive lower-house victory, bolstering investor expectations for more reflationary fiscal measures including higher defence spending and possible tax cuts. The result sent the Nikkei to fresh highs and lifted risk appetite across the region.

The benchmark Nikkei 225 jumped roughly 4.2% to an all-time high in early trading, Reuters and Bloomberg reported; Mettisglobal put the intraday peak slightly higher at about 4.4%. Bloomberg noted the Nikkei had climbed as much as 4.2% to a fresh record as of 9:05 a.m. local time. The broader TOPIX also hit a record, with Mettisglobal saying it rose 3.4% to 3,825.67 points while Bloomberg reported it was up as much as 2.6% to a new peak. Electronics and bank stocks led the advance in Tokyo, reflecting expectations that targeted stimulus will favour those sectors.

Market players framed the political outcome as a green light for fiscal expansion. Jamie Halse, managing director at Senjin Capital in Sydney, said: "Cutting the consumption tax on food is a positive for domestic consumption spending; increased military spending is a positive for defence stocks." Halse added that "the real question is what other measures may be possible now with the huge mandate granted by gaining a two-thirds majority" and that "the voters have clearly endorsed Sanaenomics, so it is possible further measures may be announced." Those comments, reported by Reuters and other outlets, crystallize investor hopes that policy will tilt toward demand-supporting measures.

The Japan-led rally spilled into other Asian markets. MSCI's broadest index of Asia-Pacific shares outside Japan rose 1.0%, Reuters reported. South Korea’s tech-heavy index (.KS11) climbed about 3.9% per Reuters, while MG News said the broader KOSPI jumped nearly 5% as Samsung Electronics and SK Hynix both rose more than 5% after reports the former will start mass production of next-generation HBM4 memory chips later this month. U.S. chip names that had rallied late last week also helped sentiment: Nvidia jumped almost 8%, Advanced Micro Devices surged over 8% and Broadcom rose around 7%, according to Reuters and Yahoo Finance.

Greater China markets advanced as well, with MG News reporting Hong Kong’s Hang Seng up about 2% and the Hang Seng TECH index adding 1.5%; mainland gauges including the Shanghai Composite and CSI 300 rose roughly 1.3%. Commodity and beaten-down momentum trades such as silver saw some bargain hunting, cited by regional outlets, as investors rotated back into risk assets.

The move also reflected a wider shift in global expectations about U.S. monetary policy. S&P 500 futures rose 0.4% and Nasdaq futures added 0.6%, Reuters and Yahoo reported, with markets pricing a rate cut by June as an "odds-on" bet according to Reuters and CNBC summaries. Traders will now look to a slew of U.S. data on jobs, inflation and spending this week for confirmation.

For markets, the twin forces of renewed fiscal stimulus prospects in Japan and easing expectations from the U.S. central bank have created a constructive near-term backdrop for equities, particularly for cyclical and technology-related sectors. The durability of the rally will hinge on the specifics of Tokyo’s policy announcements and the incoming U.S. economic data that will shape the Fed’s path.
