Stocks and oil prices rise with eyes on Iran; yen touches 40-year low vs dollar

JPY plumbing: the 40-year print

USD/JPY tagged a level not seen since the mid-1980s. Demand at the bid is one-sided; sellers are thin on every retracement. The move is not narrative — it is depth-of-book asymmetry. Per Reuters, the pair's trajectory tracks directly to the Iran-watch tape, not domestic flow.

For execution: expect widened quote gaps on tops during Tokyo handover and elevated slippage on market-on-close JPY crosses. Routing through London liquidity peaks will remain the cleanest path for size.

Cross-asset footprint

Reuters reports oil firmed alongside equities on the Iran headline. FXStreet simultaneously flags CAD stuck at 14-month lows on Fed hike re-pricing and lower crude — a clean divergence signal. Energy beta and rate-beta are decoupling session-to-session.

S&P Global notes EUR/USD-driven European corn firmed on heat-wave supply concern — a second-order rate channel propagating into softs. Sterling, Canadian, and Antipodean liquidity pools all show the same pattern: thinner resting depth, faster mean-reversion on stop runs.

Liquidity concentration

매일경제 flags a deeper concentration trend across global capital pools — order flow aggregating into fewer venues, fewer crosses. For the FX desk this translates into: fewer printed mid-prices off-session, wider effective spreads on minor pairs, and a premium on FIX-session timestamps during London and NY overlap.

Watch the next Reuters wire on Iran. A confirmed escalation risks a gap-fill in WTI and a snap re-pricing of JPY funding. Order book state at 14:30 GMT will be the first tell.
