Answer: LOOP

Based on the Snowflake documentation and community consensus with 100% agreement and upvoted comments, the LOOP construct requires an explicit BREAK statement to terminate execution. Unlike WHILE, FOR, and REPEAT loops that have built-in termination conditions, the basic LOOP continues indefinitely until a BREAK statement is encountered. The community discussion clearly supports this with multiple references to official Snowflake documentation stating that BREAK is required in LOOP but not necessary in WHILE, FOR, and REPEAT loops.
