One fund that owns about 1,500 large companies across 23 wealthy countries: the US, Europe, Japan, Australia and others. The US still dominates at roughly 70% of the fund because American companies are by far the most valuable. A solid 'one and done' core for a long-term portfolio.
See full IWDA details →Same idea as the Vanguard all-world fund: every major listed company on the planet, including both wealthy and emerging countries. This is the iShares version, on the London exchange in pence. Holdings overlap almost entirely with VWCE.
See full SSAC details →Both IWDA and SSACare Irish-domiciled UCITS ETFs, so dividends from their US holdings are taxed at 15% under Ireland's US treaty, rather than the 30% that applies to US-domiciled funds for many non-US investors, and they sit outside US estate tax. Your own local tax still depends on where you live, so check your country's rules; for most investors the main ongoing cost to watch is each fund's annual fee.

Frequently asked questions
Which is cheaper, IWDA.L or SSAC.L?
They cost the same, 0.20% per year each, so choose based on what each fund actually holds rather than on fees.
Are IWDA.L and SSAC.L accumulating or distributing?
IWDA.L is accumulating, so dividends are reinvested automatically inside the fund. SSAC.L is accumulating, so dividends are reinvested automatically inside the fund. Accumulating funds suit investors who want hands-off compounding with no cash dividends to reinvest manually.
Are IWDA.L and SSAC.L both UCITS ETFs?
Yes, both are UCITS ETFs (IWDA.L domiciled in Ireland, SSAC.L in Ireland), so both give non-US investors the 15% US dividend withholding rate and sit outside US estate tax, unlike US-domiciled ETFs.
