I can't overplay this issue though. UK gilts vs UK bills are not that far apart in terms of benefits. I asked the computer to find the best Sortino but only using UK stocks, gilts and bills so it couldn't go running to gold for protection. This is what I found:
using gilts instead to see the effects
as measured by the Sharpe
using gilts instead to see the effects
So the Sortino and Sharpe drop a little bit and the downside standard deviation increase by 1.5-2 percentage points. It's not a huge difference, one might even call it a technical tie in order to avoid being to fixed in historical data. One might even say that gilts were better because of all the fiscal problems, wars, etc and it still came close to bills. Had those bad events not happened, they would have been a much better hedge asset. So as a matter of policy, one could be better off by using them because they can still do ok in a bad enviroment. I don't know. The UK experience is certaintly not the worst that can happen, the worst is Germany in the 20's and other tail events. When these happen bills and duration bonds both get wiped out. So more research and thinking needs to be done in terms of using duration as a hedge asset
One thing that I can say is that both of them (bills and gilts) got their ass kicked by gold as hedge assets
