The LBMA is due to report their end of January silver stock report on Friday, Feb 6. I fully expect them to report another ridiculous number. In the meantime, we know some of the variables to the free float equation and we can play at estimating the others:
X = A - B + (C * D) - E - F
X = LBMA free float vault stock (end of January)
A = (27,818 Official | 24,994.5 Realistic*) LBMA vault stock (end of December)
B = (20,957 + 1,023**) ETF vault stock
C = (1,370.91) COMEX withdrawn for January
D = An estimated percentage of COMEX withdrawn that was shipped to London
E = Export to China (SGE/SFE) in January
F = Export to India in January
*Realistic
25,939 November realistic estimate - 944.5 drain
COMEX
It is unreasonable to assume that 100% of the COMEX withdrawals across the entire month were shipped to London. I think 90% for a high side conservative estimate would be reasonable. Plugging 90% in for "D" yields 1,234 metric tons.
**ETFs
SLV added 1,023 tons on Feb 2. That's 1,023 tons that end of January ETF totals won't count, but really were not LBMA free float IMO as it likely represents repayment of shares borrowed throughout January.
China
SFE silver vault drained 236 metric tons in January. SGE silver vault drained 280 metric tons in January. I think it fair to estimate that China did not export silver to London. Given the persistent SGE premium to LBMA spot, China is likely to have received silver from London. It is really difficult to estimate how much silver China may have imported from London. Let's be conservative and estimate that the LBMA exported nothing to China in January (E=0).
India
India reportedly (per Metals Focus) imported :
~480 metric tons from the UK (~1,600 tons total all sources) in October
~390 metric tons from the UK (~750 tons total all source) in November
~70 metric tons from the UK (~370 tons total all source) in December
Given that Indian silver markets have tracked China through January (at a premium to the West), it seems safe to estimate that likely did not receive much silver from the LBMA (maybe 20-30 tons is realistic?). Let's be conservative and estimate that the LBMA exported nothing to India in January (F=0).
LBMA
The following conservative estimates are upper bound base cases for LBMA vault stock assuming the LBMA exported nothing to China and India. They are likely overshooting as the LBMA probably did export at least some silver to China and/or India, but we have no idea how much yet. You can fiddle with the variables to suit your own ideas:
Feb 6 LBMA silver vault stock report will likely reflect:
Vault stock = 27,818 + (1,370.91 * 0.90) - 0 - 0 = 29,052 tons
My realistic free float estimate:
Free float = 24,994.5 - 21,980 + (1,370.91 * 0.90) - 0 - 0 = 4,248.5 (versus 3,554 tons last month)
4,248.5 metric tons is ~136.6M ozt. The LBMA ran into trouble in October when their free float was in the range of 110M ozt. As silver lease rates have been falling recently, it makes sense that the LBMA free float has some cushion at the moment.
If you want to see how ridiculous the LBMA report is on Friday, compare their report to:
29,052 tons (estimated based upon their already ridiculous report from last month)
27,173 tons (estimated using last month's realistic estimate [with import/export data])
We'll see what they say on Friday!
Final thought
I'm estimating the LBMA's *liquid* free float (136.6M ozt total FF - 110M ozt illiquid FF) for silver to be in the neighborhood of 26.6M ozt. At at spot price of $100, that's only ~$2.7B.
