That is not true. Yield is going up globally, so you need to adjust for the difference in yield.

For example, the US and Euro (average) yield have gone up by almost the same amount in that period, and other currencies like Japan and Australia have experienced an even larger increase.

Its because bond yields and fixed income in general isn't well understood by the public. Even in finance, its often not correctly understood except by those working in fixed income or the IT teams that support them. Funny thing is, often the devs in those departments understand global finance better than the CEOs running those firms because of how fixed incomes is seen by other departments. Basically, its the lowest department because it doesn't get great yield while ironically requiring the best math and economics knowledge to do.
