Why the dollar reigns supreme

This is from an older article.  The author's thesis is that the dollar's reign is about to end, but I get a different conclusion.

==============
"To understand the dollar's future, it's important to understand the dollar's past—why the dollar became so dominant in the first place. Let me offer three reasons.

First, its allure reflects the singular depth of markets in dollar-denominated debt securities. The sheer scale of those markets allows dealers to offer low bid-ask spreads. The availability of derivative instruments with which to hedge dollar exchange-rate risk is unsurpassed. This makes the dollar the most convenient currency in which to do business for corporations, central banks and governments alike.

Second, there is the fact that the dollar is the world's safe haven. In crises, investors instinctively flock to it, as they did following the 2008 failure of Lehman Brothers. This tendency reflects the exceptional liquidity of markets in dollar instruments, liquidity being the most precious of all commodities in a crisis. It is a product of the fact that U.S. Treasury securities, the single most important asset bought and sold by international investors, have long had a reputation for stability.

Finally, the dollar benefits from a dearth of alternatives. Other countries that have long enjoyed a reputation for stability, such as Switzerland, or that have recently acquired one, like Australia, are too small for their currencies to account for more than a tiny fraction of international financial transactions."
