# Yen Sinks to a 40-Year Low as the Fed Meeting Goes Live - G10 FX & The Carry Trade - Week of July 27, 2026 > G10 FX and carry-trade newsletter for the week of July 27, 2026. The yen slid to a 40-year low near 163 to 164 as the $74 billion spring intervention was fully erased, the Fed meeting turned into a genuine coin-flip on a hike with roughly one-in-three odds priced, and Britain's new government inherited a 30-year gilt yield above its 2022 crisis peak. ## G10 FX & The Carry Trade ### Week of July 27, 2026: Yen Sinks to a 40-Year Low as the Fed Meeting Goes Live --- Most weeks in currency markets, the big central banks are a slow-moving backdrop. This is not one of those weeks. Over the next few days we get rate decisions from the Federal Reserve, the Bank of England, and the Bank of Japan, three of the most important interest-rate committees on the planet, all in the same stretch of the calendar. And for the first time in a long time, the outcomes are genuinely uncertain. The Fed is now a real coin-flip to *raise* rates. The Bank of Japan is expected to sit still even as its currency slides to levels not seen since the 1980s. And Britain is walking into all of it with a brand-new prime minister and a brand-new finance minister who has already started saying things no British chancellor has said out loud in years. Here is what the podcasts actually said. ## TL;DR - **The yen just hit its weakest level in 40 years**, around 163 to 164 to the dollar, a level last seen in December 1986. The huge $74 billion the Japanese government spent buying yen back in the spring has now been completely erased by the market. Traders explained, in plain terms, why: Japan pays 1% interest while the US pays 3.75%, so borrowing cheap yen to buy dollars is simply too profitable to stop. - **The Federal Reserve meeting is "live."** Markets now put roughly a one-in-three chance on the Fed actually *hiking* rates this week, a stunning shift given how soft US inflation was earlier this month. The trigger is oil: energy prices are climbing again, and the Fed's rate expectations only seem to react when oil goes *up*. - **Britain has a new government, and the bond market is watching closely.** New PM Andy Burnham was sworn in on July 20; his surprise choice for chancellor, John Healey, used his first big speech in the City to praise "profit," the first time a chancellor has done that in years. But the UK's long-term borrowing cost is now *higher* than it was at the peak of the 2022 Liz Truss crisis, and the government's financial safety margin has been roughly halved. - **The Bank of Japan is expected to do nothing on Friday, but the whispers are getting louder.** Some officials are reportedly open to raising rates faster than their usual once-every-six-months pace, and markets are starting to bet on an October hike. Japan's finance ministry is talking tougher about defending the yen, but so far the market is simply ignoring it. - **The carry trade still works, and desks are getting specific about how to play it.** The favourite recipe: borrow the world's lowest-yielders, the Swiss franc above all, and buy high-yielding emerging-market currencies, especially in Latin America (Colombia, Brazil, Mexico), which one desk flagged as both high-paying *and* under-owned. ## What's New **1. The single most striking number of the week: the yen at a 40-year low.** The Japanese yen fell to roughly 163–164 per US dollar this week, its weakest since December 1986. Two podcasts drove the point home. On [The Rundown](http://url7324.matterfact.com/ls/click?upn=u001.idHmPrr2Geh7KYLAsTy7NkrIVb-2FgA4pmf2rMXQwGcOiqGafN5Fte-2BKIwITCd9hA6i5-2B95JZ9TeNSNShBNqiHmNniI0Ng-2B3-2FZz2I9g30G3TajbVyuA9ope0vO4Z-2BWXCpkLwf2vH6unYHC8hhl9pTIfw-3D-3D1isD_7mLGwmUci-2BLaXswv9WX1yTgqn3Wad-2FotHhzHgSNAZbUB716ZNyhDpvXEaiMzV3cHe3kbIekJ2sqtWZ7Ctjml7r8GnlzJRX06SYYdmOPqyumCaVzwf0XiLEILFPdafhs0-2F7UG7bknShD484UX8MIiioqC0zStflbnex0UaEpe3wqPxMvNBSr-2Fcvk2ExpsU9WJYiHW2D6iCeEr3yuhykQ0Hg-3D-3D) (Jul 23), the closing "fun fact" was that "the Japanese yen is now at its weakest level in 40 years... a level that we haven't seen since December of 1986," despite the government having "spent nearly $74 billion buying yen earlier this year." The blunt takeaway: that intervention "really hasn't had much impact." The clearest explanation of *why* came from an unlikely but genuinely useful source, [The Trading Coach Podcast](http://url7324.matterfact.com/ls/click?upn=u001.idHmPrr2Geh7KYLAsTy7NkrIVb-2FgA4pmf2rMXQwGcOjm0nDTmOg-2BKIPigEUmMHUkJY2PhN7vXwzNNxr-2BtpZrnDfHTL1u5XAnpNy9PfPOxE9UOreHoICgNCl1eO6a9hHvdWOq4yrtRJLjPoNJz7NJow-3D-3DiF8K_7mLGwmUci-2BLaXswv9WX1yTgqn3Wad-2FotHhzHgSNAZbUB716ZNyhDpvXEaiMzV3cHe3kbIekJ2sqtWZ7Ctjml7oKYVwIkPzme23pQyZBTQDkPhHCZDRsIDBrRqnbJJRrzSbtY-2BYQXdydHIM5rSDBipMNHaF1PyfgV8eRSkd8gpV9jQ1b728hlJylyIB9MAP3HdCFJppOcSr5gPGk9NdRq3Q-3D-3D) (Jul 26), whose whole episode was devoted to the failed intervention. The host walked through exactly what happened: on April 29 and May 1, Japan bought yen and sold dollars, spending "almost ¥11 trillion, or $74 billion." The move was dramatic, the dollar-yen "fell roughly 3%, and... more than 500 pips in just a matter of hours." And yet "less than 2 months later, the market had completely shaken off the intervention," with the yen back above where it started. His analogy for why it failed is worth quoting because it captures the whole problem in one image: > Japan was essentially trying to put a Band-Aid over a gushing wound... the market never actually saw any statistical reason for the currency to be stronger. The "statistical reason" is the interest-rate gap. He laid out the numbers side by side: "Australia, 4.35%. America, 3.75%. United Kingdom, 3.75%. The ECB... 2.40. Canada, 2.25. Japan, 1." As he put it: "Japan is the obvious outlier." When you can borrow yen at 1% and park the money in dollars earning 3.75%, you keep selling yen, and no amount of one-off government buying changes that math. His forecast: don't expect another meaningful intervention until Japan "believes that the market will actually support a stronger yen," which probably means waiting for actual rate hikes later this year (he flagged the October and December meetings) *and* for US rates to start falling. Until then, shorting the yen stays "a very profitable trade." **2. The Fed meeting is suddenly a real event.** Two weeks ago, the story was soft US inflation and a Fed that might finally cut. Now the market is pricing a serious chance of a *hike* this week. On J.P. Morgan's [At Any Rate](http://url7324.matterfact.com/ls/click?upn=u001.idHmPrr2Geh7KYLAsTy7NkrIVb-2FgA4pmf2rMXQwGcOhj1HEBDyStR9o4p-2Bkh-2BaneSQ6Ok5Pgpr9x0Pb-2ByUSQ2SW3NRZ9oUNEFXsQpI0cb-2FLsaK7IC5SBQQ3YEKa0WIEpvrCc-2B3SAIpz1ZAycys-2FFcQ-3D-3DvCPA_7mLGwmUci-2BLaXswv9WX1yTgqn3Wad-2FotHhzHgSNAZbUB716ZNyhDpvXEaiMzV3cHe3kbIekJ2sqtWZ7Ctjml7rgeBxFjVFrM4jIhhP36q3j4QbZfc1eb7H48sTPJEIOWXvY-2BNF3H4GULeBawH-2F-2F8yOBN6QpnjilkHvGGm3Yhxl7FSTvmW6XmZOWEXQouhLM6AZdVt0cVqHDFsvLrX-2FpTBw-3D-3D) (Jul 24), co-head of FX strategy Meera Chandan said "the market is pricing in... now more than a third of a chance of a hike for next week." Her colleague Patrick Locke put a number on it: "we were pricing about 9 basis points of a risk premium for a hike this meeting, which is 40-ish percent... getting kind of close to that kind of toss-up range." What flipped the mood? Energy. Chandan explained that the only thing keeping J.P. Morgan committed to a stronger-dollar view was "the extent of Fed hawkishness," their computer models measuring how hawkish Fed officials sound clocked "the largest [two-week swing] since 2022." Rising oil "added fuel to the fire." And she flagged a genuinely odd pattern: "the rates pricing for the Fed is actually showing sensitivity to oil only when prices are going up, not when they're coming down." In other words, oil going up pushes the Fed hawkish, but oil coming down doesn't push it dovish, a one-way ratchet that keeps the dollar supported. Veteran FX strategist Marc Chandler, on [The KE Report](http://url7324.matterfact.com/ls/click?upn=u001.idHmPrr2Geh7KYLAsTy7NkrIVb-2FgA4pmf2rMXQwGcOjKxXpSi15o1tBJ0NMmS5mu-2Bappfd6Z3nmhkFCHNv8hotqNEn5sudBRRiVJp4ZjHyeLczQJe6dORyi-2B6jVFjXl1G7LBSJdn0yXL9drh4Sheyw-3D-3Dfj32_7mLGwmUci-2BLaXswv9WX1yTgqn3Wad-2FotHhzHgSNAZbUB716ZNyhDpvXEaiMzV3cHe3kbIekJ2sqtWZ7Ctjml7nSy-2BuwpGntK-2B1OBXoyv-2FIR0Es7SoCW1yk9EUH8z0MDJ58Dny8NDfjS-2Fotb8zMepjWOpjq0l2LUjBK4ph26lJZ4bgOqt4mVyUrdP1Hk5WSRzPNb5y4NxxtwJqk7v8YOQkg-3D-3D) (Jul 24), agreed the odds have jumped, "the market's pricing at about a one in three chance," and said the futures market now sees "about an 80 percent chance of two" hikes this year, one in the third quarter and one in the fourth. But he personally pushed back on a move *this* week: "I would lean against a rate hike this week... I don't think [new Fed chair Kevin Warsh] wants to raise rates at his second FOMC meeting." His reasoning is a useful reminder that energy shocks are double-edged: higher oil is inflationary at first, but "the higher prices for oil act like a tax on American consumers," slowing spending down the line. Why it matters: the dollar right now is being propped up not by strong inflation, which actually came in soft this month, but by the *fear* of Fed hikes and by rising energy prices. Chandler was explicit that the real driver is the two-year US government bond yield (up about 11 basis points on the week, more than most other rich countries), and that "the dollar tracks rising US interest rates... more so than interest rate differentials." He sees the dollar index, last year's high near 110 and this year's high near 101.80, grinding up toward 102–102.5. **3. Britain got a new government, and its first moves are a study in tightrope-walking.** Andy Burnham was sworn in as UK prime minister on July 20, the country's seventh leader in a decade, as [Market Maker](http://url7324.matterfact.com/ls/click?upn=u001.idHmPrr2Geh7KYLAsTy7NkrIVb-2FgA4pmf2rMXQwGcOhO6XFW8XE5ica8Uo2XImcSSJwyDXY0axJYpVKH5K8h2AuZkbrYEnFgQcBGRjVgPKmcavhNAcJ7ZzFpUFU6zNTjBLnJFyS7UaZB5mKnsDHFcw-3D-3Drqo-_7mLGwmUci-2BLaXswv9WX1yTgqn3Wad-2FotHhzHgSNAZbUB716ZNyhDpvXEaiMzV3cHe3kbIekJ2sqtWZ7Ctjml7tLON1unXX2nsCZa3eqfG8Gsn4o4bCtwR0l1MJEoNVL5hg2npHwy0RZj2yBV2xGOAoFY3gxazmXTURSxnKU2VvXoWzWIbIzseFK-2BRzY6v2ZEIVKXmC1ZWP-2F6GeF8SJqhag-3D-3D) (Jul 23) noted. His opening salvo was a burst of cost-of-living giveaways: cutting VAT (a sales tax) on household energy bills, capping bus fares at £2 (down from £3), business-rate relief for pubs, clubs and live-music venues, and a "growth in every postcode" plan to shift investment out of the south-east and into the regions. The surprise, and the more important market story, was his chancellor. On the FT's [The Business](http://url7324.matterfact.com/ls/click?upn=u001.idHmPrr2Geh7KYLAsTy7NkrIVb-2FgA4pmf2rMXQwGcOh-2BXb9e3FHIMhh-2FJGYDtTGEQHQEw1L8VudtipqeoqSbz4f4rNm6qSD24i0Dqo-2B0tWsz5ZQ-2B1YRqCd9306AeAi2K9F4tHN0ViStZ-2BlR1ncItZw-3D-3DDmDL_7mLGwmUci-2BLaXswv9WX1yTgqn3Wad-2FotHhzHgSNAZbUB716ZNyhDpvXEaiMzV3cHe3kbIekJ2sqtWZ7Ctjml7mkO22pz8grTAQH7MPAYjRTR4dvU1iq-2FYKVRbuLhiMB29hraPM9xM4ZaZWaVNsltbOCExhSF19shYwo6NnY8oLfA3fhqvtIQKSridVkMmq6vED72bfkHhWl5F1uSQUeOhg-3D-3D) (Jul 23), the panel zeroed in on new Chancellor John Healey's very first speech, delivered that morning at a Citi conference in the City. He said he wanted "government decisions to raise the levels of investment, of innovation, of confidence, and of profit in British-based businesses." One panellist's reaction: "I don't think I've heard a politician say [profit like that] since probably maybe Cameron or Osborne... profit is no longer a dirty word." Choosing the City, rather than "an aero engine factory in the Midlands... with a hard hat on," for his first big outing was read as a deliberate, market-friendly signal. Part of the relief was simply that the job hadn't gone to Ed Miliband, whom business "was very unhappy about." The catch is the numbers Healey inherits. On Market Maker, Piers Curran of AmplifyME laid out the uncomfortable starting point: the 10-year gilt (UK government bond) yield is at 5.1%, and the 30-year is at 5.8%, actually *higher* than the panic peak during the 2022 Liz Truss "mini-budget" crisis, when the 30-year topped out "just shy of 5%." As he put it: "Burnham's starting point is a bond yield that's higher than the spike high of Liz's Truss." UK yields are now the highest of any G7 nation. **4. The chancellor's financial safety margin has already been cut in half.** Both UK podcasts hammered the same point: the buffer the government keeps to stay within its own budget rules, its "headroom," has shrunk alarmingly. On The Business, the panel explained that former chancellor Rachel Reeves left £24 billion of five-year headroom, but "about half of it's gone," and "almost as soon as we had a spring statement, half of it had gone because the Iran War had basically wiped out about £10 to £12 billion." That is not from any policy choice, it is pure arithmetic, as higher market interest rates raise the government's borrowing costs. One panellist's memorable framing: the gilt yield "is the thing that can rob a chancellor of... the equivalent of a 1p cut in the basic rate of income tax," worth "£5 to £6 billion at a splash." Market Maker put the current buffer even tighter, at around £10 billion, "basically nothing," meaning "a much, much, much finer margin of error." The real test comes at the budget in November. ## The Debate **On one side: the dollar stays firm, the yen keeps sliding, and carry keeps paying.** This is the mainstream desk view. J.P. Morgan is "still constructive, generally speaking, on the dollar pre-FOMC," Chandan said, with energy prices doing the heavy lifting. The firm's energy team even sketched the pain thresholds that would force Washington's hand: if supply disruptions run another month, average US gasoline "is likely to rebound to $4.20," and after two months "the prices could go back to $4.50." Marc Chandler's charts point the same way, a dollar index carving out a year-long base and "just a fraction off... breaking to 52-week highs." And on the yen specifically, the logic is almost mechanical: with Japan at 1% and everyone else far higher, there is no fundamental reason for the currency to strengthen, so the path of least resistance is weaker still. **On the other side: the hawks may be over their skis, and something could snap.** Chandler himself, despite his bullish dollar chart, does not think the Fed hikes this week, he expects Warsh to wait for "the July jobs data in early August." And on carry, the loudest warning came from Peter Schiff on [The Peter Schiff Show](http://url7324.matterfact.com/ls/click?upn=u001.idHmPrr2Geh7KYLAsTy7NkrIVb-2FgA4pmf2rMXQwGcOhcRlbdkyrdBdooG-2FCmYgZx-2F08130A88DFscqwkherhvk0DEUW5CmgQZ1-2F1iyCxjqKz0cZuFNxyZbkWBWFC02DsFqbdrGlLuHVTyf5PfcFPuQ-3D-3DV69O_7mLGwmUci-2BLaXswv9WX1yTgqn3Wad-2FotHhzHgSNAZbUB716ZNyhDpvXEaiMzV3cHe3kbIekJ2sqtWZ7Ctjml7s1uR0u15xaRRdya1tWp8ayzLBgy1lQECz2QOIcrvfN3VxjxA-2BmTUINhn-2F1FKoUr7czTFpPXrhMMrPSslAux8zq8HKxfX2MNoYTfCol27Xj17JdsWuK20dQGdnEcTJhGgg-3D-3D) (Jul 26). Schiff is a perennial bear and this is a pundit's macro call, not a trading-desk forecast, but he laid out the mechanism cleanly. Japanese government bond yields are climbing fast: the 10-year at 2.8% ("the highest... since 1996") and the 30-year at nearly 4% (a record). With Japan's debt above 200% of its economy and the policy rate still at just 1%, he argues the Bank of Japan will eventually be forced to hike hard, "at least to 3% from 1%." Either it acts aggressively and triggers a crisis at home, or it stays timid and the yen crashes. And here is the read-through for everyone else: Japan's government owns "over $1.1 trillion in treasuries," it is the single biggest foreign owner of US government debt, so if it ever sells to defend the yen, the shockwaves land squarely on US markets. His word for it: "dominoes." **Where the debate is genuinely one-sided this week: the Swiss franc.** Beyond a passing mention of the strong franc squeezing Swiss exporter Roche's reported sales, and its role as the go-to funding currency (more on both below), there was no fresh commentary this week on the Swiss National Bank, Swiss deflation, or where EUR/CHF goes next. The franc story is quiet right now, better to say so than to manufacture a view. ## Trades in Play - **The carry recipe, spelled out.** The most concrete idea came from State Street's [Street Signals](http://url7324.matterfact.com/ls/click?upn=u001.idHmPrr2Geh7KYLAsTy7NkrIVb-2FgA4pmf2rMXQwGcOg9aJBuqzccRfsJPvFkQ23haacTio-2F5L3UkHiZ56C-2BzE1Ba0xSJzXG7hsGJBX4vV4Q7RT0DTOUjKz2AtiSEBMMr9w-2Fy0iAFPq9HjTiEyhgh4g-3D-3DU9X2_7mLGwmUci-2BLaXswv9WX1yTgqn3Wad-2FotHhzHgSNAZbUB716ZNyhDpvXEaiMzV3cHe3kbIekJ2sqtWZ7Ctjml7u860CVg5WvegYDVvEc1-2Bw5eLwKDzx9iFnDeTewmrEGTzs5CrxW-2BwPywXEUYam0prWfbRRUD0zGOsL9I9GXordTzoTlbtHz0nCHpSCasbedfNCZcv0KOeIshDo3u-2F3SBbA-3D-3D) (Jul 23). The strategist argued that the highest-yielding emerging-market currencies are also, unusually, the *least crowded*, "especially Latin America and particularly Colombia, Brazil, and Mexico. None of these currencies are overweights in our FX holdings measures." Their local bonds pay far more than anything in the rich world "with only modestly higher currency volatility," and many of their central banks can still cut rates from high levels, which tends to lift those bonds further. The trade is to fund those positions by selling the lowest-yielders: in the developed world, "the one that really stands out is the Swiss franc, the lowest yielder of them all," and among Asian exporters, the Taiwan, Korean and Chinese currencies, all of which are heavily over-owned. - **How to actually trade the Fed meeting: watch the dissents.** Because this is a Fed meeting without updated forecasts, Locke said the dollar reaction will hinge on how many officials formally disagree with the decision: "a couple of dissents would be dollar positive on the day, and any more than a couple, 3 or more... would certainly be very constructive for the dollar." - **The dollar's own options look cheap, a late-summer setup.** Street Signals flagged a wrinkle worth filing away: even though institutions are "selling the dollar aggressively" and building bets against it, the options market makes bets *on* the dollar look inexpensive, "especially the Japanese yen." Their read: near-term dollar weakness against high-yielders is likely, but "the short-term dollar losses we might see could be very good long-term buying opportunities" later in the summer. ## Read-throughs - **Japan's finance ministry is talking tougher, and being ignored.** On [Bloomberg Daybreak](http://url7324.matterfact.com/ls/click?upn=u001.idHmPrr2Geh7KYLAsTy7NkrIVb-2FgA4pmf2rMXQwGcOhsf5WO65W-2FzbLkU7qwhK8qDXYnhTnVJq-2FHAJSl1vaAeLjQ0haC1AYIlsewzw45sZjSSc5C5fuGnEKkwvuwtgemYAH5wZRURAGH4gNb5altsg-3D-3D-5gK_7mLGwmUci-2BLaXswv9WX1yTgqn3Wad-2FotHhzHgSNAZbUB716ZNyhDpvXEaiMzV3cHe3kbIekJ2sqtWZ7Ctjml7rdIuHMqc9yBMaS-2FqmECaeLZ8SnADAOyD26-2B6qAUQWkRbm2EHigw9Az-2BlDslfCggDu0-2FOZBf0FPUk1obZ2NJG8GOThXewOfl1UiwHwU3i-2BknjOMvUTg3M5jOdO7tfgOAcA-3D-3D) (Jul 24), Tokyo-based reporter Molly Smith said Finance Minister Katayama has "sounded a bit more forceful with her language" in recent days, shifting to "we will take bold action as needed or decisive action as appropriate," the kind of phrasing that in Japan is code for intervention. The tell: "there hasn't really been a subsequent reaction in the yen... the markets are pretty unconvinced." Any actual intervention would probably wait until after Friday's Bank of Japan meeting. - **The Bank of Japan is expected to hold, but the door to faster hikes is creaking open.** Smith noted the BoJ raised its rate to 1% in June, "the highest in 31 years," and is widely expected to hold on Friday. The interesting part is a Bloomberg report that some officials are "open to raising interest rates at an accelerated rate," faster than the informal every-six-months pace. That would normally mean the next hike in December, but "you have seen growing market odds that there could be another hike by October." Governor Ueda, she expects, will stay deliberately vague and "would not want to commit to any kind of predetermined path." - **Bunds and gilts vs. Treasuries: Europe is the weak grower.** Marc Chandler expects Europe's second-quarter growth at roughly 0.2% for the quarter, under 1% annualised, against US growth he pegs at 1.7% to 2.2%. That growth gap, plus a rising energy-import bill, keeps the euro on the back foot. On At Any Rate, Chandan noted that European gas prices (the TTF benchmark) have "already exceeded the highs we saw in March, April," which is "quite problematic for the euro," which is exactly why J.P. Morgan likes using the euro itself as a funding currency to buy higher-yielders. - **Swiss exporters are wearing the strong franc.** On [Squawk Box Europe Express](http://url7324.matterfact.com/ls/click?upn=u001.idHmPrr2Geh7KYLAsTy7NkrIVb-2FgA4pmf2rMXQwGcOitA1oFoQbYHTKb0baI8jCQPLHa2GMwX0pk-2FTCXa0-2F210eJpRIvKcq-2BUtj-2FJtKFEvuG1nJu3to3hKIcTjJFi-2B12z7sN4hTr0t3vUCgVQZKVFg-3D-3DJE5l_7mLGwmUci-2BLaXswv9WX1yTgqn3Wad-2FotHhzHgSNAZbUB716ZNyhDpvXEaiMzV3cHe3kbIekJ2sqtWZ7Ctjml7o-2Fd0PthCAdiVjrd4L6lnf0GiLKcyoR87IRWQSO1nkfnoeo7IdouMNjWBkj3qfJ1K4ABL5NCyOS5E9dckr3EThK7hlMj6MDVxJIPTLv6DyP2gbLFjBrn7YPhaoznoDjuVg-3D-3D) (Jul 23), Roche CEO Thomas Schinecker acknowledged that "the Swiss franc continues to appreciate" and dented reported first-half sales (just over CHF 30 billion), the company grew 6% in constant currencies but "actually growing 8 percent" measured in dollars. His one piece of reassurance: if today's exchange rates simply hold, "there would be no impact" in the second half. It is a neat illustration of how a strong funding currency quietly taxes the earnings of Europe's exporters. - **Why the yen matters to a US stock investor.** Both The Rundown and Peter Schiff pointed at the same nightmare scenario, a replay of September 2024. When investors borrow cheap yen to buy US stocks and bonds, a sudden yen spike can force them to sell those assets in a hurry to repay their yen loans. As The Rundown put it, that "famously happened not too long ago, back in September of 2024. The yen rallied, and the markets tanked for a couple of days." Nobody expects it this week, but a surprise Bank of Japan hike, or a real intervention, is the fuse. ## What Changed Last week the frame was a slow, synchronised turn across the rich world away from rate cuts and toward rate hikes. That is still the backdrop, but this week it sharpened into three specific, near-term events. The Fed meeting went from "maybe a hike in September" to a genuine coin-flip *this week*, with roughly one-in-three odds priced in. The yen slid to a fresh 40-year low, quietly erasing the last trace of the $74 billion the Japanese government spent defending it in the spring, and put the Bank of Japan's Friday decision, plus the growing chatter about an October hike, front and centre. And Britain's political drama got real names and real numbers: a new prime minister, a surprisingly market-friendly new chancellor, a long-term borrowing cost now above its 2022 crisis peak, and a financial safety margin cut roughly in half. The through-line is the same as it has been all summer, a firm dollar, a cornered yen, and a carry trade that keeps paying right up until the moment it doesn't. But this is the week the calendar forces the issue. --- ## Get the full transcripts on Matterfact This briefing was produced with Matterfact, which indexes the complete, full-text transcripts of 120M+ podcast episodes alongside SEC filings, earnings calls, and financial datasets.
