Sterling exchange rates: Economic indicators

Economic indicators are quick-read summaries of the latest data focusing on different aspects of the UK economy. The full suite of indicators can be found on the main Economic Indicators page.

The Sterling Exchange Rate Index (SERI) measures sterling’s value against a ‘basket’ of currencies, ‘trade‑weighted’ (based on currencies’ relative importance in UK trade).

The SERI fell by 0.6% between August and September, having increased by 0.2% between July and August. It was 0.3% higher in September compared with a year earlier. It is 19.3% below its January 2007 peak.

Between August and September, the value of the pound decreased by 1.0% against the dollar, to $1.34. The value of the pound reached $1.43 in April 2018, its highest level since the EU referendum. The pound fell to $1.08, its lowest ever level, in September 2022 (based on daily spot exchange rates). Sterling fell by 0.3% against the euro between August and September, to €1.17.
