New Zealand household wealth shot up 14.1% and wealth per adult rose 12.9%. Japan’s was a spectacular 19% plus jump for both households and individuals.
No other countries increased by double figures, though there were plenty who lost a lot of wealth – for example, Argentina down 27.3%, Ukraine at 18.5% and Russia at 15%.
At the global level, overall wealth was up less than 2% and that is basically static when population growth is taken into account.
The wealth is calculated on financial assets including stocks and bonds, non-financial assets – mainly property, and subtracts debt. The change in New Zealand’s household wealth is due to three major reasons: a rise in house/property prices, a 23% rise in the sharemarket and a dollar that rose 5.3% against the US dollar.
Currency appreciation, or depreciation, has an important impact in measuring world wealth trends as the report is based on US dollar values.
For example, Japan and the US had the greatest increase in wealth because their currencies rose, while the Brexit-induced 15% fall in the UK pound depressed the total wealth of Britons by $US1.5 trillion – or $US288,000.
Wealth in Switzerland and Norway also fell, because European currencies were weaker, though it didn't affect their country rankings that much.
