# razor thin (margin)

*Ordinarily means:* Very small in thickness or amount.

The range between two walls has narrowed so far that no drift can occur without crossing one, and maintenance can no longer act without risk of breakage.

## Examples
- In 2023, Taiwan Semiconductor's 3nm chip production faced yield drops when voltage margins narrowed to under 50mV, leaving no room for thermal drift. *(engineering)*
- The 2008 financial collapse followed decades of shrinking capital reserve ratios, until banks held less than 2% against obligations. *(economics)*
- During the 1961 Berlin Crisis, U.S. and Soviet tanks at Checkpoint Charlie were separated by 10 meters, with no room for maneuver without collision. *(institutions)*
