Out of total global investible assets worth $230trn, commodity futures make up less than $500bn, or 0.2%.

在价值 230 万亿美元的全球可投资资产总额中，商品期货不到 5000 亿美元，即 0.2%。

Investment represents the demand for investible resources and saving represents the supply, whilst the rate of interest is the 'price' of investible resources at which the two are equated.

投资代表对可投资资源的需求，储蓄代表供给，而利率是使两者相等的可投资资源的“价格”。
