Range-bound, rolling over within the range · RSI 49 · price 1.33679

Multi-quarter range 1.3010-1.3870; price back in the lower half after losing ema50.

Cable has been range-bound between the 1.3010 range low and the 1.3869 range top for four quarters, and the last two months' grind up to 1.3675 failed to break that ceiling. Last week's wide bearish weekly bar erased the advance and closed at 1.33679, back below the W1 EMA(50) at 1.3422 — the macro filter that has capped and supported alternately since Q1, and which also sits on the 50% retracement of the Nov-Jan swing. The driver is the policy differential flip: the Fed hiked to 3.75-4.00% while the BoE held at 3.75% on a 6-3 vote, compressing sterling's carry advantage. RSI(14) at 48 is mid-range and carries no information at this scale.

Support: 1.3300, 1.3140, 1.3010

Resistance: 1.3422, 1.3675, 1.3869

What it said to watch

  • Weekly close below the 1.3300 psych level would expose the 1.3140 swing low as the next range reference
  • Reclaiming the 1.3422 ema50 on a weekly close would restore balance in the upper half of the range
  • A weekly close above 1.3675 prior high is the only condition that puts the 1.3869 range top back in play
  • Failure to hold 1.3010 range low would end the four-quarter range regime
  • UK Retail Sales and next week's flash PMIs are the near-term tests of the below-capacity narrative behind GBP's carry erosion

Range-bound, lower highs since January · RSI 48 · price 1.33679

Wide 1.3160-1.3675 range, price back in lower half.

Cable has been range-bound between roughly 1.3160 and the 1.3675 range high since February, with the January print at 1.3869 standing as the prior-yr high and each subsequent rally topping lower. The latest week erased the summer advance and closed at 1.33679, back under both the W1 EMA20 and the 1.3422 EMA50 — the macro filter now sits above price for the first time in the current up-leg. The driver is the policy gap: the Fed hiked to 3.75-4.00% while the BoE held at 3.75% on a 6-3 vote, compressing sterling's rate advantage.

Support: 1.3315, 1.3160

Resistance: 1.3422, 1.3675, 1.3869

What it said to watch

  • Weekly close back above the 1.3422 w1 ema50 would restore the mid-range read
  • Loss of the 1.3315 swing low on a weekly close opens the 1.3160 range floor
  • Sustained trade above 1.3675 range high needed to reopen the 1.3869 prior-yr high
  • UK Retail Sales and next week's flash PMIs are the near-term tests of the below-capacity narrative
