Air pockets and political landmines: Asia eyes a tricky Tokyo Tuesday open

Asian markets tiptoe into Tuesday with more tension than conviction. U.S. stocks gave back most of Monday’s early gains as traders sifted through earnings with one eye nervously fixed on the calendar—August 1 is fast approaching, and with it, the specter of tariff escalation. Like April lore, the “Tariff Bogeyman” could leap out of the bushes at any moment, especially in these summer tapes filled with air pockets and thin liquidity.

Layered on top of that is yet another frontal assault on the Fed, this time from Treasury Secretary Scott Bessent I, who openly called for a sweeping internal review of the Federal Reserve’s non-monetary operations. Translation: the Fed’s wandering into policy areas that could undermine its core mission. His comments weren’t just a shot across the bow—they practically set the table on fire. Safe to say Powell’s next breakfast with Bessent will be less "coffee and croissants" and more "eggshells and daggers."

Meanwhile, Japan returns from its Monday holiday to a political hangover. Prime Minister Ishiba is still clinging to power despite his coalition's upper house setback, and while that offers a sliver of continuity, it’s a wobbly kind. The Tokyo cash open is under scrutiny, not just because of the election results, but because Japan's markets—true to form—are capable of being both insular and emotionally fragile.

Initial investor reaction was evident through the yen, which rose nearly 1% against the dollar on Monday, more out of a reflex to unwind weekend hedges than conviction, though. Nikkei futures in Osaka barely moved, but the mood feels anything but settled. Japan may find some short-term shelter from the relief rally in global debt markets, but that cover is thin as rice paper. This week, Japan risks a full-blown “triple dunk tank”—stocks, bonds, and currency all plunging in sync—if fiscal clarity remains elusive. And if super-long JGB yields continue their upward march, the yen could be next on the chopping block.

Traders are bracing for a bearish steepening in the JGB curve, especially in the 20- to 40-year zone, as pressure mounts on Ishiba to appease voters demanding tax cuts and inflation relief. Any fiscal concessions will likely push yields higher and rattle an already jumpy market. As one strategist put it, “policy uncertainty and political fragility is a recipe for yen depreciation—not strength.”

While the Topix has bounced since April’s tariff tantrum, it’s still well off last year’s highs, and the latest round of political noise threatens to erode broader investor confidence. Short-term, a weaker yen might offer exporters a tailwind, but sectors like utilities, construction, and banking—those most tied to domestic policy—could take the brunt of any pullback. Defensives like healthcare may provide a haven, but the broader outlook remains fragile.

With earnings surprising to the upside, it’s tempting to think the market might take full flight. But between tariffs, central bank drama, and political fragility in Japan, this rally still feels like it’s being piloted with one eye closed and the eject button half-pressed.
