Thesis
Post-Iran-shock, the G4 central banks are diverging rather than moving in lockstep: ECB skipping (Sept live), BoE looking through the oil shock toward eventual easing, BoJ the hawkish holdout with an October-hike setup, and the Fed hold-then-cut. Mechanism: relative-policy paths drive the FX crosses (6E/6B/6J) and the front-end differentials (SR3 vs European/JGB rates). Successor framing to the now-fractured global-tightening-cycle meta-theme.
Development timeline
- Jul 13: REVIVED from declining — LBMacro reframes the Iran energy shock as pushing G4 CBs hawkish SIMULTANEOUSLY (a convergence, cutting against the divergence framing): ECB house view now another +25bp on energy-driven upside inflation; BoE at risk of ABANDONING 'look-through' toward a hike on second-round effects; BoJ Oct hike now ~65% priced on wage growth >3% for a 4th month + 3yr-high PPI; Fed two more hikes on hawkish Minutes. Euro/US yields already +10bp last week on the repricing; Stoxx 600 worst week since April even as US tech-led indices rose. Single primary source (LBMacro) — one desk's read, not yet cross-outlet.

- Jul 6: new theme — independent research (lbmacro weekly) maps a G4 divergence now that the coordinated-tightening read has fractured: ECB expected to SKIP in July (softer Sintra + June core HICP undershoot, Sept hike still open); BoE's Bailey seen 'looking through' the oil shock as consumer inflation expectations fall; BoJ Q2 Tankan firmed record inflation expectations + easy credit, reinforcing an October BoJ-hike call despite political pressure. Single-source, not yet corroborated.Sources: independent channels
Upcoming catalysts
- ECB July meeting — expected skip (Sept hike still on table)
- BoJ October hike call (lbmacro, on firm Q2 Tankan) — UNCONFIRMED
