The more interesting wrinkle is in South Korean bonds, where both the three-year and ten-year yields ticked slightly lower even as global bonds, per <a href=\"https:\/\/investinglive.com\/education\/how-rate-hikes-and-expectations-of-them-ripple-through-stocks-and-gold\/\" rel=\"follow\">Mohamed El-Erian&#8217;s recent comments<\/a> on a broader sovereign sell-off, face renewed upward pressure. That&#8217;s a live divergence worth tracking: if Korean yields continue decoupling from the global bond weakness El-Erian described, it points to idiosyncratic domestic demand for Korean debt holding up even as reliable buyers of US and European government bonds reportedly thin out. Japan&#8217;s rally is a different case. The stated rationale, that a calmer bond market and steadier yen from Treasury Secretary Bessent&#8217;s actions eased volatility, sits uneasily next to the reported facts in the same piece: <a href=\"https:\/\/investinglive.com\/news\/investinglive-americas-market-news-wrap-big-beat-for-non-farm-payrolls\/\" rel=\"follow\">Wall Street actually fell Friday<\/a> on rising Fed hike odds, with only the semiconductor sub-index bucking that decline. Crediting a broad &#8220;risk-on&#8221; shift to bond and currency calm, while the source material shows the opposite happening in US rates and a narrow, chip-specific rally rather than a market-wide one, is a gap worth flagging rather than repeating uncritically.<\/p>\n<p dir=\"ltr\">&#8212;<br \/>\nKorea&#8217;s chip-and-currency rally has a clean story behind it; Japan&#8217;s stated rationale for its own rally is harder to square with what actually happened on Wall Street.<\/p>\n<p dir=\"ltr\">Summary:<\/p>\n<ul dir=\"ltr\">\n<li>South Korea&#8217;s Kospi rose around 2.9% to about 6,880, having climbed as much as around 3.5% intraday to its highest level since 27 August<\/li>\n<li>Samsung Electronics gained around 3.7% and SK Hynix rose about 6%, leading the benchmark higher on AI chip demand optimism<\/li>\n<li>The Korean won hit its strongest level since October 2024, with foreigners net buyers of roughly 790 billion won (about $590 million) in shares<\/li>\n<li>South Korea&#8217;s three-year and ten-year government bond yields both edged slightly lower, a notable contrast to the upward pressure on global bond yields described elsewhere this week<\/li>\n<li>Japan&#8217;s Nikkei rose around 2.3% to about 66,500, with the attributed rationale being calmer bond markets and a steadier yen easing broader market volatility<\/li>\n<li>Wall Street actually fell on Friday as a strong jobs report lifted Fed rate hike odds, with only the semiconductor index bucking the decline, a detail that complicates the stated case for Japan&#8217;s rally<\/li>\n<\/ul>\n<p dir=\"ltr\">\nSouth Korean shares and the won rallied to start the week, driven by chipmakers riding optimism around AI investment demand, while Japan&#8217;s Nikkei also advanced on a rationale that deserves closer scrutiny. The Kospi rose around 2.9% to about 6,880, having climbed as much as roughly 3.5% intraday to its highest level since 27 August, with Samsung Electronics up around 3.7% and SK Hynix gaining about 6% to lead the index.<\/p>\n<p dir=\"ltr\">The Korean won hit its strongest level since October 2024 amid expectations of continued dollar selling by major exporters, while foreigners were net buyers of roughly 790 billion won, about $590 million, worth of shares. South Korea&#8217;s exports so far this year have already surpassed last year&#8217;s full-year record, underscoring how much the economy is currently riding on global AI chip demand.<\/p>\n<p dir=\"ltr\">The more interesting detail sits in South Korean bonds. Both the three-year and ten-year government bond yields edged slightly lower on the day, a genuine point of contrast with the broader global bond picture described by economist Mohamed El-Erian in recent comments to CNBC, where he warned of continued upward pressure on yields driven by a shrinking pool of reliable buyers for government debt worldwide, though El-Erian did not comment on Korea specifically. If that divergence holds, it suggests Korean bonds are, for now, being driven more by domestic demand dynamics than the buyer-base concerns El-Erian flagged for markets like the UK, Japan and France.<\/p>\n<p dir=\"ltr\">Japan&#8217;s Nikkei rose around 2.3% to about 66,500, with the Topix up around 0.8% to roughly 4,136, as chip-related shares tracked gains in their US counterparts. A circulating narrative, that US Treasury Secretary Scott Bessent&#8217;s actions had curbed bond yields and stemmed yen weakness, reducing volatility and encouraging a shift to risk-on positioning, is worth treating with some caution. The same reporting notes that Wall Street actually fell on Friday, as a robust US jobs report raised the probability of a Federal Reserve rate hike this month, with only the Philadelphia Semiconductor Index, up around 3.4%, bucking that decline. A narrow, chip-specific rally against a backdrop of broader US equity weakness and rising rate expectations is a different story than the calmer, risk-on narrative offered for Japan&#8217;s gains, and the discrepancy is worth keeping in mind before taking the stated rationale at face value.<\/p>\n<p dir=\"ltr\">\n<p dir=\"ltr\">\n<p dir=\"ltr\">\n<p>                            This article was written by Eamonn Sheridan at investinglive.com.<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"<p>The Kospi move looks like a coherent, chip-led story: exporter dollar selling supporting the won, foreign inflows into equities, and a genuine global AI demand tailwind visible in Samsung and SK Hynix&#8217;s&hellip;<\/p>\n","protected":false},"author":216,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[86],"tags":[],"class_list":["post-437580","post","type-post","status-publish","format-standard","hentry","category-market-news"],"_links":{"self":[{"href":"https:\/\/www.swingfish.trade\/blog\/wp-json\/wp\/v2\/posts\/437580","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.swingfish.trade\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.swingfish.trade\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.swingfish.trade\/blog\/wp-json\/wp\/v2\/users\/216"}],"replies":[{"embeddable":true,"href":"https:\/\/www.swingfish.trade\/blog\/wp-json\/wp\/v2\/comments?post=437580"}],"version-history":[{"count":0,"href":"https:\/\/www.swingfish.trade\/blog\/wp-json\/wp\/v2\/posts\/437580\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.swingfish.trade\/blog\/wp-json\/wp\/v2\/media?parent=437580"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.swingfish.trade\/blog\/wp-json\/wp\/v2\/categories?post=437580"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.swingfish.trade\/blog\/wp-json\/wp\/v2\/tags?post=437580"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
