## 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.

## Watching

ECB July skip confirmation + Sept guidance; BoE 'look-through' vs Mann's activist-hike threat; BoJ Q2 Tankan follow-through into Oct-hike pricing; whether other channels corroborate lbmacro's divergence read.

## Development timeline (dated, source-cited)

- 2026-07-15: Jul 15: the convergence-hawkish read (logged Jul 13) partially UNWOUND by the CPI reversal — Monday's parallel jump (ECB 2-hike-by-YE 35%→60%, BoE 15%→64%, Fed July 35%→45%) reversed Tuesday post-CPI on the US leg, though ECB 2-hike odds still sit ~60% into next week's decision (hike risk elevated) — leaving cross-CB paths less lockstep than Monday implied.

- 2026-07-13: 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. Sources: independent channels. [independent channels]
- 2026-07-06: 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. [independent channels]
