# Source Document Not Available

The source document for the 30-Year KTB Auction (KR) on 2026-03-31 could not be retrieved.

**Reason:** 
1. **Network Access Denied:** Direct attempts to reach the Korea Ministry of Economy and Finance (MOEF) and the KTB portal resulted in `Connection reset by peer`. This typically indicates that the host's IP range is blocked or the server has strict anti-scraping measures.
2. **Search Verification Failure:** A deep search via Perplexity (sonar-pro) failed to locate an official press release or auction result matching the specific yield (3.78%) and date (March 31). The official MOEF issuance plan for March 2026 scheduled the 30-year auction for March 4, not March 31.
3. **Market Mismatch:** While secondary market yields for the 30-year bond were trading around 3.80% on March 30, no primary auction announcement from the official issuer was found to confirm the 3.78% result for this specific date.

**Indicators requested:**
- 30 Year Bond Yield (Actual: 3.78%, Previous: 3.52%)
