Emerging markets rally hard

The fastest money in markets spent the week doing a full U-turn: traders who had been hiding from war risk rushed back into emerging-market stocks as oil fell and ceasefire headlines made the Strait of Hormuz look less likely to shut. The result was a 5.1% jump in the MSCI Emerging Markets index, its biggest one-day move since 2022. (msci.com) (markets.ft.com) That reaction starts with oil, not equities. When fighting near the Gulf threatens shipping through the Strait of Hormuz, countries that import a lot of energy get hit first because every tanker of crude and liquefied natural gas suddenly looks more expensive. (cnbc.com) (news.northeastern.edu) South Korea is the cleanest example. On April 8, the Korea Composite Stock Price Index, the country’s main stock benchmark, jumped 6.87% to 5,872.34 after reports of a tentative United States-Iran ceasefire tied to keeping shipping open through Hormuz. (koreajoongangdaily.joins.com) South Korea imports most of its energy, and its stock market is packed with exporters like Samsung Electronics and SK Hynix that benefit when investors stop pricing in an oil shock and a supply-chain jam at the same time. That is why the Korea Composite Stock Price Index moved harder than many larger markets. (en.sedaily.com) (bloomberg.com) Turkey rallied for a different reason. Turkish banking and airline shares led a more than 4% rise in Turkish stocks on April 8 as the lira strengthened and traders treated a two-week ceasefire as relief for a country that sits close to the conflict and is heavily exposed to swings in energy prices and regional risk. (english.aawsat.com 1) (english.aawsat.com 2) Banks in places like Turkey act like a lever on confidence. If investors think oil stays lower, inflation cools, and the currency stops sliding, bank shares can jump much faster than the overall market because their loan books and funding costs both look less dangerous. (akbankinvestorrelations.com) (english.aawsat.com) South Africa joined the move even though it is far from the Gulf. Its Top 40 index had surged roughly 6% in the relief rally before slipping back, because global investors often buy and sell South Africa as part of one big “emerging markets” basket, especially when commodity prices, bond yields, and the dollar all move together. (tradingeconomics.com) (resbank.co.za) Then there is Vietnam, which was rising for a second reason that had nothing to do with the ceasefire. On April 7, FTSE Russell confirmed Vietnam will enter its Secondary Emerging market group in September 2026, and Vietnam’s market regulator said that could bring in about $6 billion of foreign money. (msn.com 1) (msn.com 2) That kind of upgrade works like adding a country to a major sports league. Funds that track FTSE Russell benchmarks often have to buy the market simply because the rules of the index changed, so Vietnam can get inflows even if no portfolio manager suddenly “discovers” Hanoi this week. (vietnam-briefing.com) (msn.com) Put together, this was not one story but three trades landing on the same day: lower oil helping importers like South Korea, lower fear helping fragile markets like Turkey, and index-rule changes helping Vietnam. Emerging markets rallied hard because traders suddenly had fewer reasons to demand a discount all at once. (cnbc.com) (msci.com)
