Gas riches and the original 'Dutch disease'

The discovery of the giant Groningen gas field in 1959 and the rapid ramp-up of production through the 1960s and 1970s - reaching roughly 85 billion cubic meters a year by 1976 - turned the Netherlands into a major energy exporter almost overnight, and gas revenue rose from under 1% of GDP in 1973 to around 5% by 1981, nearing a tenth of total state income by the early 1980s. De Nederlandsche Bank's own occasional study of the episode traced how that windfall financed a rapid expansion of welfare spending while the associated appreciation of the guilder made the rest of Dutch industry steadily less competitive abroad, hollowing out manufacturing even as the broader economy looked prosperous on paper. The Economist coined the term 'Dutch disease' in a 1977 article describing exactly this combination of resource wealth, a strong currency, and industrial decline. The pattern is visible in the Netherlands' own long-run charts as a period of comparatively weak non-energy export growth and elevated government spending through the late 1970s and 1980s, before the 'Polder Model' reforms of the 1980s and 1990s restored competitiveness ahead of eurozone entry in 1999.
