Withdrawals were down roughly 33% in April from March - just barely staying above December's low rate. A reminder that December's low rate lead to the LBMA running into trouble in January. This level of flow from COMEX to LBMA was not sufficient support for the LBMA to satisfy physical demand from India and China (and @Viking ).
This is the reason that my run rate estimates have blown out lately. The 5 DMA withdrawal rate is reflecting near record low withdrawals lately.
I expect the withdrawal rates to climb again as they did in January. May is going to be an interesting month for silver flows.
