[socialcredit] Capital adequacy (was: 10 can't pay 11 fallacy, again) Date:

Hi John,
By using the search facility in
the web site of the Reserve Bank of New Zealand under the heading 'capital
adequacy', one encounters the following page: http://www.rbnz.govt.nz/search/index.asp?q=capital+adequacy&submit=Search
According to article number 3, entitled Capital adequacy ratios for
banks , we learn that the following conditions must be fulfilled as a requirement for
the registration of banks in in New
Zealand:
1. The ratio of tier 1 capital to risk weighted assets must be no
smaller than 4%. 2. The ratio of total capital to risk weighted assets (capital
adequacy ratio) must be no smaller than 8%. 3. Tier 2 capital must not exceed
tier 1 capital. 4. Lower tier 2 capital must not exceed 50% of tier 1 capital. 5.
Lower tier 2 capital must be amortized over the last five years of its
life.
This conforms to an international standard known as the Basle 1
convention, which was promulgated in 1988 by the Bank for International
Settlements. A complete explanation of what tier 1 and tier 2 capital are
comprised of can be found in the above article. And for some reason the RBNZ
article prefers to use the term 'credit exposures' rather than 'assets'.
The
minimum capital adequacy ratio of 8% implies that the ratio of risk weighted
assets RWA to total bank capital
K (ie, the weighted financial assets which may be 'supported' by that capital)
is 100 / 8 = 12.5. For loans to entities within New Zealand, and considering only
on-balance sheet exposures, the risk weightings are:
1. Claims on banks
(A1) 20% 2. Claims on the public sector (A2) 20% 3. Residential
mortgages (A3) 50% 4. All other credit (A4)
100%
For off-balance sheet exposures the risk weightings are even more
complicated. The ratio of total supported assets A to capital K is only equal to
12.5 in the special case where all loans fall into risk category 4. In general
the ratio A/K will be somewhat greater than 12.5. For example if A1=X, A2=0,
A3=3X and A4=3X (where X is some arbitrary quantity of money), then A/K = 18.6.

Thanks. Anything as precise as "12.5" inferring a high degree of accuracy is
unusual, to say the least. I certainly had never heard of it, and obviously our
Royal Commission had not, but bnthen that is half a century dated now. Just what
is it based on, and when was it propounded? Regards. John R.
- Hi John,
- The ratio that I mentioned has nothing to do with reserves as such or the
reserve ratio. It is the capital adequacy ratio, and to my knowledge it applies
all over the planet, even in countries like New Zealand which have a zero reserve
requirement. Moreover reserves don't matter much these days, even in countries
like the U.S. which retains a significant statutory reserve requirement (that's
because banks can always borrow whatever excess reserves they require - from
within the financial system - for their volume of lending). Each bank's lending
is now primarily constrained by the magnitude of its regulatory capital in
relation to its assets.
