The Bank of England’s sterling effective exchange rate strengthened on the month in July, and ONS import-price inflation cooled from June’s peak. Local retailers and manufacturers should still plan on imported materials and finished goods costing more than a year ago, without treating any short-run FX move as a forecast.
Colchester’s High Street, Tollgate-style retail parks and light-industrial estates around Severalls and the Northern Gateway all sit downstream of the UK’s import bill. A weaker pound tends to raise sterling prices of overseas goods; a stronger pound can ease that pressure with a lag. The latest official data point to a modest sterling firming in July alongside cooler annual import-price inflation, not a clean return to cheap imports.
What the exchange-rate data show
The Office for National Statistics publishes the Bank of England’s sterling effective exchange rate index (ERI, series BK67, January 2005 = 100) alongside producer-price statistics. In July 2026 the monthly-average sterling ERI stood at 85.6. That was a 0.9% rise on June (84.8) and a 0.6% rise on July 2025.
The path through 2026 has not been one-way. The same ONS table shows the index at 85.1 in January, dipping to 84.5 in March, then fluctuating around the mid-84s before July’s rebound. Annual rates switched from a 1.4% fall in the year to June to a 0.6% rise in the year to July. Sterling’s trade-weighted value was a little firmer in July than in June, but the year-on-year gain is small.
The next ONS trade release that updates related monthly series is 11 September 2026. July remains the latest full monthly average in the producer-price bulletin of 19 August 2026. Spot rates move daily; this piece does not invent a September forecast or a Colchester-specific FX path.
Import prices and factory costs
The Import Price Index (IPI) measures sterling prices of materials and fuels imported by UK manufacturers. In the year to July 2026 the IPI rose by 5.2%, down from a revised 9.0% in the year to June. Monthly import prices fell 2.5% between June and July. The ONS attributes the annual rise mainly to non-EU imports of refined petroleum products. That matters for Essex manufacturers and logistics even when finished retail goods are the public face of imports: fuel and feedstock feed into distribution and process costs before shelf prices move.
Broader producer input prices rose 4.9% in the year to July (down from a revised 7.4% in June). Monthly input prices fell 1.7%. Factory-gate output prices rose 3.1% on the year. Cost pressure has eased from the spring peak but remains clearly positive. August PPI is due 16 September 2026.
Trade volumes: June and Quarter 2
The latest UK trade bulletin covers June 2026 (released 13 August 2026). Goods imports excluding precious metals were £54.0 billion, down 0.7% on May. Non-EU imports fell 1.0% and EU imports 0.3%. In chained-volume terms, goods imports rose 1.1% in June. In Quarter 2, goods imports rose 4.3% on Quarter 1; the ONS links large fuel swings partly to higher oil prices associated with Middle East disruption. These are national figures, not Colchester or Essex port breakdowns, but they confirm a large ongoing import stream.
Local implications
Retail stockists buy a mix of EU and non-EU finished goods. A 5.2% annual IPI rise is not identical to retail cost of goods sold, but it is a verified signal that imported materials and related factory costs remain higher than a year earlier. July’s monthly IPI fall and sterling’s monthly rise, if sustained, could ease replacement costs with a lag. Contracts and earlier inventory still sit on balance sheets.
Light manufacturers and food processors are more directly exposed to the IPI and input PPI. Petroleum-related import strength can dominate the annual rate even when sterling is stable. Firms should separate the verified July cooling from any assumption that costs will keep falling.
Pricing. Pass-through depends on demand, online competition and when stock was bought. This desk will not invent a Colchester margin figure. Import costs remain elevated on a year-ago basis; July’s FX and IPI moves lean slightly towards relief, not a guarantee.
Uncertainty flags
- July is the latest complete month for sterling ERI and IPI; August PPI is due 16 September.
- July UK trade is due 11 September; June figures can be revised.
- FX pass-through to local shelf prices is lagged; no local survey is cited here.
