Historical analysis · current-data companion
The dashboard now uses the July 2026 WDI vintage through 2025. Ghana’s 2025 GDP is US$114.21 billion, but its 2025 trade ratio is missing. This archived calculation retains its original 2019–2023 vintage; use the refreshed dashboard for available later observations and do not combine vintages.
Read the September 2026 data briefing →Key finding
The reconstructed trade total increased by about 0.06%, while trade relative to GDP fell by 5.73 percentage points in 2023.
The denominator changes the interpretation
Multiplying the published ratio by nominal GDP gives an indicative trade total of US$51,832.0 million in 2022 and US$51,864.2 million in 2023. The difference is only about US$32.2 million. GDP in the same extract increased from US$73,919 million to US$80,547 million. Consequently, a sizeable reduction in the ratio can occur without a comparably large fall in its dollar numerator. The ratio alone would therefore be a poor basis for asserting that cross-border commercial activity contracted sharply.

The longer comparison remains mixed
The 2019 trade ratio was higher still, at 76.82%. Across 2019–2023 it fell by 12.43 percentage points. Yet this is an annual national-accounts series expressed against a changing GDP denominator. It cannot isolate whether changes came from traded quantities, prices, currency conversion, domestic activity or revisions. Describing this movement as a decline in real trade would add a conclusion that the available observations do not establish. The useful finding is narrower: relative exposure changed more than the nominal trade total.

What a business research team should investigate
An importer should examine its own purchase volumes, unit costs and settlement currency alongside aggregate trade. A services exporter needs a series that includes its activity and a clear distinction between invoices and receipts. A market-sizing model should retain both the ratio and the underlying value, with consistent dates and units. These checks would help determine whether a sales movement reflects customer demand, prices or the way a national indicator is expressed. No firm-level effect is estimated in this brief.
Method and reference period
The calculation is trade value = GDP in current US$ million × trade (% of GDP) / 100. It uses WDI observations as presented by WITS, rather than customs merchandise totals. The indicator includes goods and services. Values are indicative because GDP is rounded to whole millions and ratios to two decimals in the source extract. Displayed changes use unrounded intermediate calculations.
Limitations
Current-dollar values are not measures of real growth and include exchange-rate and price effects. The reconstruction is an arithmetic check, not a replacement official series. It is not directly comparable with the merchandise export values used in the separate sector brief. These historical observations end in 2023 and are not a 2026 forecast.
