With a further reduction in the government budget surplus corresponding to half a per cent of GDP each year for the next ten years, the budget surplus excluding the return from the Petroleum Fund will gradually be reduced by 5 per cent of GDP compared with the traditional calculations in the generational accounts. At the same time, the accumulation of capital in and hence the return on the Petroleum Fund will be smaller. Given an oil price of NOK 90 per barrel, the expected increase in the budget deficit will fail to materialise.
