Notes & assumptions: Daily = P × rate / 365; Monthly = P × rate / 12. "3-Day Interest" approximates the opportunity cost of funds in transit for three calendar days. Monthly Interest calculated as (Annual Rate ÷ 12) × 100M local currency, then converted to USD. USD conversions use spot rates captured at ~16:00 UTC on 30 Sep 2025. Real provider rates/fees vary; adjust inputs as needed. Brazil rate reflects latest BACEN Selic target (15.00%); Singapore uses SORA benchmark (~1.50%); Qatar uses QCB lending rate (5.10%); Hong Kong uses HKMA base rate (4.50%).
