International Issues

Putting aside domestic payments for
the moment, international dollar payment system risk issues involve both
onshore and offshore privately
operated networks that transfer dollars
between domestic and/or foreignrelated banking institutions. Participants accumulate net credit or debit
positions as payments clear during the
day. At the end of the day, net debit
positions are paid from Federal
Reserve Bank deposits (directly or via
correspondents) and are redistributed
to participants in net credit positions.
The Clearing House Interbank Payments System (CHIPS), operated by
the New York Clearing House, is the
onshore example of such a network for
multilateral position netting. The
Chase-Tokyo Clearing is an offshore
example.
Systemic risk is the central regulatory
concem in these private networks.
Using current CHIPS as an example,
total payments of about $700 billion are
made through CHIPS each day, involving an average $45 billion peak daylight overdraft exposure of net creditposition banks to net debit-position
banks. CHIPS agreements among participants don't protect against systemic
risk: a defaulting participant's payments
and receipts are to be backed-out of the
day's transactions, and a new settlement
struck, but with no mechanism for

In any case, moral hazard implications
should make the presumption of rescue
unacceptable to the Federal Reserve,
whether implicit or explicit. That is, if
the Federal Reserve could be counted
on to mount a rescue, the probability of
needing a rescue would increase as the
market discipline of counterparty credit
scrutiny eroded.
Which nation's authorities are responsible in payment systems with multina. tional participants is an issue that is
only beginning to receive attention,
partly instigated by the larger
regulatory issues of host country versus
country of residence questions arising
in banking. Which authorities should
be concerned with dollar payment networks operating offshore, and for dollar payment system activities of foreign
banking institutions participating in onshore networks are complicated issues.
The central banks of the 10 major
developed nations, the G-l 0, are currently exploring these issues, with the
assistance of the Bank for International
Settlements (BIS).
The Federal Reserve has been urging,
and CHIPS has now agreed to adopt, internal guarantees of shared funding by
all network participants in the event that
any participant is unable to cover its
deficit position on the network at the
end of a day. This would reduce or
eliminate systemic risk by assuring settlement without a chain-reaction of
failures.

shared funding are required of all onshore private payment networks, offshore networks may become more attractive. Or pairs of banks may simply

tle those payments directly.
The second important implication of a
CHIPS risk-sharing agreement is that
the Federal Reserve can toughen requirements for users of its own networks because of the reduced concem
that removing direct credit risk might
simply add to systemic risk. This might
be the result if users of Federal Reserve
networks could avoid their risk controls
by moving payments traffic to private
networks with less constraining controls .

Domestic Issues

The Federal Reserve in effect operates
two large-dollar-value electronic payment networks, Fedwire and the
securities wire. Fedwire simply transfers reserve deposits between banks as
they send payments. A common transaction would be one in which the corporate customer of one bank instructs it to
pay the corporate customer of another
bank. But the lion's share of the dollar
value of payments arises from interbank
overnight federal funds lending and
repayment, and from trading in securities markets. The securities wire transfers U.S. Government securities in
book-entry form against payment from
reserve deposits, reflecting transactions
involving U.S. Government securities,
Daylight overdrafts originating on Fedwire became subject to a generally nOI1constraining upper limit in 1986. Each
user has a self-determined daylight overdraft limit, calculated within Federal Reserve guidelines. The Federal Reserve
Banks record each bank's daylight over-

Daylight overdrafts originating on the
securities wire have not been subject to
any explicit limitations. Reducing daylight overdrafts from this source is
made difficult by their concentration at
a handful of banks intimately involved
in the clearing and settlement of most
daily trading in U.S. Government
securities,
The paramount issue here is whether to
treat daylight overdrafts from this
source on a par with those on Fedwire,
or to develop a policy that accommodates them. The latter alternative would
minimize potential disruption of the
U.S. Government securities market, although it could discourage development of private book-entry systems.
Collateralization of overdrafts with the
securities being transferred would
reduce Federal Reserve risk exposure,
but acquiring a perfected interest in the
securities is not always possible.
The Federal Reserve Board of Governors has concluded that it will combine
overdrafts originating from funds transfers and securities transfers into a
single total, subject to a quantitative
limit. While an overdraft originating
from funds transfers alone will not be
allowed to exceed the limit, an excess
originating from securities transfers
can exceed the limit provided that the
entire overdraft is collateralized by
some combination of securities being
transferred and other acceptable collateral. This avoids disruption of the
Government-securities market by al-

Pricing Daylight Overdrafts

How to price daylight overdrafts on the
Federal Reserve networks was one
issue that emerged in recent System
staff studies. Initially, three proposals
gained attention. One was Federal
Reserve Governor Wayne Angell's suggestion that banks borrow the amount
of any daylight overdraft as a collateralized loan from the discount window at
a penalty rate. In conjunction with the
further proposal that the System pay a
below-market rate of interest on excess
reserves, the Angell proposal amounted
to a stick and a carrot that would induce banks to hold sufficient excess
reserves to avoid daylight overdrafts.
A second proposal, originating with the
Federal Reserve Bank of New York,
would have had banks hold interest
earning supplemental reserve balances
in proportion to their daylight overdrafts. This would have required banks
to hold more excess reserves directly,
but not necessarily by enough to eliminate daylight overdrafts completely.
The third proposal, and the one that the
Board of Governors has published for
public comment, simply would phase
in a slight fee of a quarter of one percent at an annual rate on the average
daily overdraft position of a bank in excess of a deductible. For example, a
very large bank with a $1 billion daily
average overdraft in excess of the deductible would pay $6,850 per business
day, or $1.8 million per year.
How high this

issue. Pricing can resystem risk to the extent
banks to make risk-

reducing changes in their payment practices, For example, many banks that
borrow overnight federal funds go into
daylight overdraft when they repay at
the beginning of the next day. They
then reborrow from identical sources
toward the end of the day. A large share
of daylight overdrafts represents this
Federal Reserve daylight bridge-

One alternative, expected to gain
widespread use, is for borrowing
banks to repay only the net difference,
if any, between the amount borrowed
from another institution on successive
days. The balance would be held as a
repeated overnight loan on terms
renegotiated daily. The fee would be
effective not because banks paid it, but
because they avoided paying it by
reducing dependence on daylight credit.
For another example, banks might
switch payments to existing or newly
formed private payment networks that.
under the Board's policy, must include
arrangements for assuring settlement
finality. The fee would be effective in
reducing direct credit risk of the
Federal Reserve, while risk-sharing
agreements like those about to be introduced in CHIPS would protect against
increased systemic risk.

•

An Operational Issue

Developing a long-run Federal Reserve
payment system risk reduction program
requires a robust definition of a daylight
overdraft. To be operational, the definition must allow banks to monitor their
daylight overdraft positions on a realtime basis during the day.
The issue is how a daylight overdraft
monitor should incorporate credits and
debits to a bank's balance from offline
activities such as check clearing, currency shipments, ACH payments, Treasury
items, etc. Rules applicable to these activities only specify the day, not the
time of day, on which funds are available. Currently, the System's ex-post
daylight overdraft monitor adds the net
amount of almost all of these offline activities to the monitor as a single daily
adjustment. The adjustment is to the
opening balance, if a net credit, or to the
closing balance, if a net debit.
The current procedure cannot continue,
if banks are expected to pay for daylight overdrafts, because a bank could
