Zakat on Foreign Stocks and Multi-Currency Portfolios

Short answer: Convert everything into one currency (normally your home currency) at the prevailing exchange rate of your zakat day and add it all up. If the total exceeds nisab, pay 2.5% — in any currency, so long as the full value is delivered. Wealth spread across currencies or countries does not get separate nisabs — one owner, one reckoning. Details: All fiat currencies stand in the place of gold and silver as one money-type class — switching dollars/taka/riyal never breaks the hawl. Use the rate at which you could actually convert (bank/lawful market rate). Foreign-brokerage shares follow the same rules as local ones — market value if trading, the long-term method otherwise; net dividends after withholding tax are what enter the books. Evidence: Quran 9:103 (wealth wherever and in whatever form); Sahih al-Bukhari 1454; Sahih Muslim 1587 (exchange of monetary metals hand-to-hand); the Permanent Committee and Shaykh Ibn Baz on fiat currencies as money whose values consolidate for zakat.
