When you purchase a bank instrument like a BG or SBLC, you pay roughly 50% of its face value upfront. The provider reinvests your funds—say €50 M—into trading ventures over the year, often securing returns well above 10% weekly, enabling the full payment of the instrument at maturity. Remember: banks themselves don’t issue these they simply deliver instruments on behalf of vetted providers, confirming underlying funds via SWIFT messages like MT‑760. Only high‑net‑worth clients with custodial accounts can access these private bank instruments, making genuine providers rare and selective. Curious how the purchase‑own a bank instrument works? When you buy a BG or SBLC at half its face value, you hold the full face value at maturity—doubling your investment. For example, acquire a €100 M instrument for €50 M, then cash it after one year. The provider reinvests your €50 M in trading programs (like commodities), earning around 10 % weekly. Over 52 weeks, that compounds to massive returns—enough to cover the full payout and share profits.
