CNB (Czech National Bank)

Overview

CNB provides monetary policy data, including the 2-week repo rate used to estimate mortgage rates.

Data access

The ARAD REST API requires registration. Instead, we use freely available plain-text history files at cnb.cz/cs/casto-kladene-dotazy/.galleries/.

Format

• Pipe-delimited text files
• Czech decimal commas (, instead of .)
• Approximately 306 records

Mortgage rate

The mortgage rate is synthesized as repo_rate_2w + 2.5 percentage points (spread). If real MFI data (mortgage_rate_avg) is available, it takes priority.
