Can I insure my business against capital loss?
No, but you can insure against certain things that may be the root cause of a capital loss. You can insure nearly any physical assets (building, cars, etc.) that you own. You can negotiate for lease or loan terms so that rental and interest expense is more predictable. You can possibly hedge against price volatility for your raw materials (depending on what your input materials are). You can make sure that you have sufficient liability insurance. Etc.
