# Source Document Not Available

The source document for the "Foreign Exchange Reserves" release by the Central Bank of Turkey (TCMB) for the period ending March 20 could not be retrieved.

**Reason:** 
The institutional website (tcmb.gov.tr) returned 404 Not Found for all predicted URL paths for the "Weekly Money and Banking Statistics" release. Direct search via Perplexity AI failed due to an unauthorized API key (401), and manual navigation via `curl` was inhibited by deep URL structures and potentially dynamic content or strict user-agent/session requirements that couldn't be resolved within the tool call limit.

**Indicators requested:** 
- Foreign Exchange Reserves (TR)
  - Actual: 61.29 (TRY Billion/USD Billion equivalent)
  - Previous: 55.49
