Maybe not all, but certainly the vast majority of the most popular asset bubbles since before even the Tulip Mania of 1637 (including the Kipper and Wipper [3]currency debasement of the German 30 years War, circa 1621, which is appropriately enough deja vu in contemporary retrospect, only the war is missing). While it may be worth noting that all the bubbles to the right of center have been central-bank induced (except for that amulet bubble of 2006, although even that is likely debatable), we will not note it as it is quite obvious even without us highlighting this simple fact. One can only imagine what would happen to asset prices - all of them - when the world's central banks, which are now collectively and voluntarily "all in" on reflating the biggest asset bubble of all time across all asset classes, decide to close the liquidity spigots (if ever).
