GBP/USD opened the week recovering part of Friday’s slide and stalled below the mid-1.3500s, having closed Friday at 1.35307 after a 0.43% decline. The pair briefly climbed above 1.3550 during the European session before retreating, and it sits at one-week lows following another failure at resistance near 1.3650. UK markets are closed for the Summer Bank Holiday, which removes the domestic bid entirely. Sterling has no fresh catalyst from its own side of the pair today, and it has not had one for weeks. The Bank of England has been on hold since July, the next decision is September 17, and the domestic calendar between here and then is essentially empty. That is the defining structural feature of this pair right now. Every pip of movement in cable has to come from the dollar leg. Friday demonstrated it. Federal Reserve Chair Kevin Warsh’s Jackson Hole address pushed September hike odds from 35.4% to 59.7%, the dollar index rose 0.4% to 99.57 in its strongest single-day gain in about two months, and every major fell against it. Sterling lost 0.43% to 1.35307, the euro 0.57% to 1.15830, the Australian dollar 0.40%, the New Zealand dollar 0.63%. USD/JPY rose 0.42% to 159.972 and has since broken 160. Notice the ranking. Sterling fell less than the euro, less than the New Zealand dollar, and roughly in line with the Aussie. That relative resilience is not accidental and it is the core of this forecast.
The cross rates confirm the same picture. GBP/JPY trades around 216.40, retreating from an intraday high near 216.85 as the yen firms on Bank of Japan hike expectations running near 84% for September. GBP/EUR sits near 1.1696 with 1.1650 as the level bulls need to defend. The thesis: sterling is trading a dollar story with a domestic anchor that neither helps nor hurts. The Bank of England is neither hiking nor cutting, September odds sit at roughly 15%, and the pound’s support comes from carry — a 150 basis point advantage over the euro and a 35 to 45 basis point gilt premium over Treasuries — rather than from anything happening in Britain. The technical structure is a well-defined range with a ceiling the pair keeps failing to clear. GBP/USD reached roughly 1.36 in late August, its strongest level since mid-February and a six-month high. It failed. It approached 1.3650 again and failed. Friday’s decline took it back below 1.3550 and Monday’s bounce stalled beneath the same zone. The prior structure explains the level. Sterling bottomed at 1.3165 on June 24 near a seven-month low and based again at 1.3280 on July 28. It printed a swing high close to 1.3520 around July 31 into August 1 on the back-to-back central bank holds, pulled back to 1.3420 to 1.3430, and climbed through 1.3460 by August 5 and 1.3490 by August 10. A dotted resistance line near 1.3480 marked the level the rally kept failing to clear before it finally broke.
The 2026 range frames how much room exists. The low is 1.3204 and the high is 1.3817, a spread of just over 4.5%. That high was set in late January, before a March tariff shock dragged the pair to approximately 1.31 and a June political event pushed it back toward 1.32. Monday’s intraday map is tight. On the four-hour chart the 100-period simple moving average at 1.3559 is capping the upside, reinforced by the 23.6% Fibonacci retracement at 1.3579 sitting just above the consolidation zone. Initial support is the 38.2% retracement at 1.3521. Below that, 1.3480 to 1.3500 flips from broken resistance to first structural support. Beneath it, 1.3420 to 1.3430 is the August base and 1.3340 marks the ascending boundary of the summer structure. A break of 1.3340 targets 1.3204 and then the major 1.3000 to 1.3170 zone. Overhead, clearing 1.3579 opens 1.3650, and above that the 1.36 to 1.37 band is the first meaningful obstacle before the 1.3817 January high. The dollar move that hit cable was not sterling-specific and it was not subtle. Warsh told Jackson Hole that inflation data are more concerning than labor-market trends, that inflation is unlikely to return to target on its own, and that the Fed will have work to do if policymakers are not confident underlying inflation is heading to 2%. He cited PCE at 3.7% against the 2% objective, noted that more than half of tracked goods and services saw price increases of 3% or higher over the past year against roughly one-third in the two decades before the pandemic, and described financial conditions as not restrictive.
September hike odds jumped to 59.7% from 35.4% on Thursday and 39.9% a week earlier. December odds moved to 80%. The two-year Treasury yield ripped 11.97 basis points in a single session to 4.352%, its highest since July 24, while the thirty-year held flat at 5.19% and the ten-year rose less than four basis points — a bear flattener. That curve shape matters for cable specifically. A bear flattener says the market expects tightening that works, containing long-end inflation compensation rather than signalling a prolonged cycle. Sterling’s carry advantage sits at the front end, where the damage was concentrated, but the gilt premium sits further out, where nothing moved. Monday brought partial relief. The two-year eased two basis points to 4.32%, the dollar backed off from Friday’s spike, and cable recovered part of its loss. One session of consolidation is not a reversal, but the market declining to extend the move on a day carrying a live U.S.-Iran escalation is informative. The renewed Middle East tension is the second dollar support. U.S. forces struck Iranian rocket launchers on Larak Island in the Strait of Hormuz on Sunday, Iran fired on U.S. air bases in Jordan, and Brent gained 3.5% to $91.20. Safe-haven demand into the dollar compounds the rate story. Market pricing at 58% is a lean rather than a done deal — the Fed tends to validate expectations once pricing crosses 60% to 70%, and certainty reads above 90%. That gap is where sterling’s recovery room lives.
