Will world interest rates fall further?

This chart shows the GDP-weighted world central bank discount rate (bank rate/Fed Funds rate/central bank lending rate) covering 83% of the world economy, as well as the median of world interest rates that I monitor . The median is the point in a series of data values at which half the observations are above and half below.  It is unweighted.  

The two different kinds of average interest rates usually move in more or less the same direction, though not always.  The GDP-weighted average will be dominated by the largest economies, the median is skewed more towards smaller economies, because they are more numerous.  Note how the median interest rate rose much more than the average before the 2009 GFC, likely making the recession worse; and how the jump in the median rate in 2011-2012 signalled that smaller economies were in trouble, worsening the downturn linked to the euro crisis.

Right now, the median is falling faster than the GDP-weighted average, which is consistent with my "small 15" average PMI index, which has been much weaker than the "big 8" index.  

Will interest rates fall further?  Well, yes, but not by much.  The ECB (European Central Bank) seems happy with its bank rate; the Fed is muttering about not cutting rates again; and the "small 15" PMI is rising fast, meaning smaller economies have become more reluctant to cut rates.  At the same time, world inflation has levelled off after falling from the post-Covid highs.  What is certain is that the low interest rates of the 2009 to 2021 years will not be reached again in this cycle.  Unless the AI-bubble pops .....
