It's June 2020. You're a senior treasury engineer at Wirecard AG in Munich. Wirecard is a DAX 30 component, market cap once €24 billion, marketed as Germany's only true Silicon-Valley-style fintech. The balance sheet shows €1.9 billion of cash held in escrow in two Philippine banks, BDO Unibank and Bank of the Philippine Islands, supporting Wirecard's Third-Party Acquiring business. For three years your reconciliation script has accepted PDF statements provided by an external 'trustee' rather than direct API or letter responses from the banks themselves. This week, after the Financial Times' Dan McCrum spent five years documenting irregularities and EY refused to accept trustee-routed evidence any longer, the COO has finally green-lit a direct reconciliation against the banks' systems. You are the engineer who has to run it. The result will end Wirecard within 72 hours.
