"Lords of Finance" is surely a book worth reading, albeit not easily. While I link one review for anyone's reading, I share my observations.
While the issue of the gold standard is no longer relevant as it was during the period under study (1920-1944), the other issues of addressing the value of one's own currency as it impacted the currencies of other nations and vice-versa remains perennially pertinent. The balance between the need for liquidity and credit within one's own nation can never be isolated from what is happening elsewhere. The author's ability to capture the ever changing landscape of international finance following WWI through 1944 is singularly insightful and clear, given the inherent difficulty in understanding the underlying transactions occurring within and between nations.
In short, I may not be any smarter, but I am more aware of the problems in maintaining an appropriate balance among all the factors included in monetary policies.
