Why the M2 counter moves: reading the HKD trend estimate
Understand the clock-based M2 projection, its reference month, annual growth assumption and the difference from published statistics.
What does a moving number represent?
The moving HKD total illustrates what a smooth continuation of an observed annual M2 trend would look like at the displayed time. It is not a measurement of actual money creation during the last second. More decimal places make motion visible; they do not increase the accuracy of the forecast. The displayed currency unit is a scale for readability, separate from the source reporting unit.

How is the estimate calculated?
Let B be the latest available observation and P the observation exactly 12 months earlier. The continuous annual rate is ln(B/P), and the displayed estimate is B × exp(ln(B/P) × t/Y), where Y=31,556,952 seconds and t is time since the reference month ended. The site anchors t at the next month’s first day, 00:00 UTC. This is a modelling convention, including for monthly-average source series. If B or the exact year-earlier observation is unavailable, no trend is invented.
What happens on a later visit or a data update?
The value depends on the current clock, not the time you opened the page. Reloading later therefore continues the trajectory. Pause freezes the display; resume catches up to the clock. A newly deployed observation changes the base and growth rate, so a jump is possible. An already-open page needs reloading to receive the new dataset. A declining annual trend produces a falling counter; a flat trend stays flat.

What should you cite or compare?
Use observed monthly data for historical comparisons. If you quote the counter, record the currency, displayed unit, reference month, timestamp and “trend estimate” label. It has no probability range and is not an official forecast. Demo data remain synthetic even when the counter moves. The projection does not establish future inflation, an investment return or a policy outcome.
Questions & answers
Does the counter reset whenever I open the site?
No. It uses elapsed time from a fixed reference point. The device clock affects the displayed instant, and a new dataset can change the projection.
Why can the counter differ from a chart total?
The chart uses published monthly observations. The counter extends a trend beyond its reference point, so the two describe different things.
