Boboo the bear flies above a forest in a hot-air balloon

This week, the trees shook wildly. One day +4.4%, the next −5.7%.
But rise in a hot-air balloon, and the river's direction barely changed.
Following the paths of money, we look down on today's forest.

Five Stories in the Forest

A slightly bigger picture among the shaking trees
1

Rates, Not War, Hold the Controls Now

When oil rises, "the Fed might hike" → stocks and gold fall. When oil falls, a relief rally follows. War news now reaches share prices only through the inflation → interest-rate channel. Ceasefire reports were therefore digested not as a peace rally, but as an interest-rate rally.

2

The AI Forest: Fourth Doubt, Unbeaten Prices

Doubts over demand → funding → efficiency (Kimi K3) → now competition (China's CXMT listing +500%). Yet actual memory prices were still +168.5% year on year in June; through the entire crash, DDR5 spot prices never fell for even one day. This week's SK hynix and Samsung earnings provide the first judgment.

3

The Ceasefire Learning Curve — Faster the Third Time

Repeated news makes prices move faster. The premium built up to $139 in the opening war panic was erased on the third ceasefire attempt by the headline alone, in a day. Next week's Red Sea observations — whether ships actually sail — will tell us whether it is real.

4

Only the Won Is All-Weather

The won strengthened through rallies, crashes, and ceasefires. That is not a bet on one scenario, but structure: a reversal in foreign flows + policy (pension-fund FX hedging) + spillover benefits from a weak yen. The next thresholds are 1,450 and the early-August balance of payments.

5

Pieces of a Bottom — Collected, Not Assembled

Crypto, the canary in the coal mine, turned up after 21 months. Today, as foreign investors sold KRW 2.9tn, retail investors and institutions absorbed it for the first time. New catalysts appeared too: NVDA → Naver $1bn and a Korea–US $950bn AI partnership. On the other side are the CXMT competition narrative, continued foreign selling, and depleted deposits. From last week's "no bottom signal," we have moved just one step to "pieces exist, but are not assembled".

The Neighboring Forest, Japan — A Mirror Image

If Korea is "won strength + an exporter correction," in Japan the weak yen itself divides sectors across the forest.

But this whole picture hinges on Thursday and Friday's BOJ meeting. A hawkish surprise or FX intervention would unwind the entire weak-yen trade (mining, shipbuilding, exporters), benefiting depressed domestic-demand and property stocks. Some money that left Japan has already reached Korean government bonds — when the yen turns, that bridge shakes too.
