So back to topicdoes anybody knows if this loans for the british government were secured to 100% of value ?
Few if any loans are ever secured at 100% of their value.
The amount of collateral put up by the Entente for each loan waxed and waned over the course of the war as "informed" opinion; i.e. bankers and the Federal Reserve, waxed and waned regarding the possibility of an Entente victory. That means you can't say loans in 1914 needed X% collateral, loans in 1915 needed Y% collateral, and so forth. Each new group of loans would have had collateral levels set by the size of the loan, it's provisions, the course of the war, and other concerns at the time the loan was guaranteed.
One thing is certain in all of this however. In late 1916 the Federal Reserve had circulated a memo to US banks stating that all Entente loans made in 1917 would require collateral levels so high as to make those loans impossible for the Entente to receive. While the Entente wasn't exactly going to run out of money, the Entente's "credit card" was going to be frozen.
Then Germany restarted USW, sent the Zimmerman Telegram, and basically committed suicide.
Blondie pretty much explained what an Entente default or partial default would have meant to the US economy. There would have been a short, sharp depression, but not a Great Depression, because real assets, not those primarily valued by bubble prices as in the recent worldwide real estate crash, would still exist.
