**Note: As of 1 July 2021, this dataset now includes several enhancements, which we believe improve the accuracy and usability of the data.
- Fund aggregation: funds that include more than one asset or sub-asset class are now grouped and displayed as a single product. This allows tracking of total assets of individual funds over time more easily. This change applies mainly to various European funds (and a few other regions) which, for example, offer different listings of the same fund structure and that were previously treated in our universe, for simplicity, as distinct products.
- Holdings accuracy: the estimation of gold holdings by converting net asset values (NAVs) of the different funds to tonnage now uses relevant regional gold price benchmarks for funds in China and India, which we believe is more precise. Previously, for ease of calculation, we used the LBMA Gold Price PM for all funds. Thus, differences between those benchmarks and the LBMA Gold Price, whether due to timing or due to local premiums, could result in a less accurate estimation of the gold holdings. This was especially noticeable for funds listed in China and India during days when the gold price experienced significant moves or there were regional holidays.
- Previously, changes in tonnes were calculated by converting a fund’s AUM (in USD) into gold holdings (in tonnes) and computing the difference over periods. However, currency movements and large daily and weekly gold price movements could distort the difference between tonnage change and US-dollar fund flows during short time horizons. We therefore adjusted tonnage change as a function of fund flows versus AUM and replaced the tonnage change field with fund flows (tonnes).
- Now, for most funds, we estimate US-dollar fund flows, as described in section 2.3.2 below, and then convert those flows to fund flows (tonnes).
Fund flows (tonnes) and US-dollar fund flows will now represent a more aligned explanation of investment demand for gold ETFs, while the true holdings of a fund, in US dollars and tonnage, will remain a close estimate, impacted by the currency and price volatility described above. - Based on our initial analysis, the changes are not likely to have a material long-term effect on historical information, particularly on a global or regional aggregate basis, but will adjust short-term fluctuations that can sometimes occur due to input data and timing variations.
- As of 1st September the fund flows data includes an additional tab showing tonnage flows (Delta tonnes) for monthly and daily periods.
These changes may lead to some – generally minor – revisions of historical data.
