    One of the main reasons the economic and financial crisis became sosevere was that the banking sectors of many countries had built upexcessive on- and off-balance sheet leverage.

    This was accompanied by a gradual erosion of the level and quality of thecapital base.

    At the same time, many banks were holding insufficient liquidity buffers. The banking system therefore was not able to absorb the resulting systemic

    trading and credit losses nor could it cope with the re-intermediation oflarge off-balance sheet exposures that had built up in the shadow bankingsystem.

    The crisis was further amplified by a procyclical deleveraging process andby the interconnectedness of systemic institutions through an array ofcomplex transactions

    Liquidity

    Asset and liability mismatch generates not only interest raterisk liquidity risk

    Different meaning of liquidity:

    Security ease with which it can be cashed back or traded, even

    in large amounts, on a secondary market

    Market liquidity of the securities traded in the market differentproxies of liquidity (e.g. bid-ask spread, volume)

    Affected by many factors: n. mkt participants, size & frequency of trades,degree of informational asymmetry, time needed to carry out a trade

    Function of tightness (markets ability to match supply and demand at lowcost) and depth (ability to absorb large trades without significant price impact)

    Financial institutionability to fund increases in assets and meetobligations as they come due, without incurring high losses

    Generally proxied by the difference between the average liquidity of assetsand that of liabilities

    11/54

    Liquidity risk

    Liquidity risk risk that a financial institution may not be able to pay back its

    liabilities in a timely manner because of an unexpectedly largeamount of claims

    more realistically, it may be able to meet those requests only byquickly selling (fire sale) large amounts of assets, at a price that isbelow their current market value, thereby suffering a loss

    The role of banks in the maturity transformation of short-term deposits into long-term loans makes banks

    inherently vulnerable to liquidity risk

    Liquidity risk depends not only on the final maturity ofassets and liabilities, but also on the maturity of eachintermediate cash flow, including the early pre-payment

    of loans or the unforeseen usage of credit lines

  • 7/29/2019 8 Liquidity Risk

    12/54

    Liquidity risk

    2 types of liquidity risk

    Funding risk risk that a F.I. may not be able to faceefficiently (i.e. without jeopardising its orderly operationsand its financial balance) any expected or unexpected

    cash outflows Market liquidity risk risk that a F.I., to liquidate a sizable

    amount of assets, will affect the price in a considerable(and unfavourable) manner, because of the limited depthof the market where the assets are traded

    The two risk types are connected a F.I. wishing to faceunexpected cash outflows may need to sell a largeamount of securities potential sharp fall in price

    Funding liquidity risk

    Relevant factors Contractual maturity of assets and liabilities Optionality in bank products e.g. demand deposits,

    guarantees issued, irrevocable loan commitments (e.g.

    SPVs related to securitization or CP programs),derivatives involving margin requirements

    Two main type of events

    Bank specific events events that distress the

    confidence of third parties rating downgrades(especially relevant when covenants or triggers minimum rating required)

    Systemic events e.g. market disruption, liquidity dry up(e.g. recent financial crisis)

  • 7/29/2019 8 Liquidity Risk

    14/54

    Funding liquidity risk

    Three main measurement approaches Stock based approach

    Measures the stock of financial assets that can promptly beliquidated to face a possible liquidity shock

    Cash flow based approach Compares expected cash inflows and outflows, grouping them in

    homogeneous maturity buckets and checking that cash inflowsare large enough to cover cash outflows

    Hybrid approach Potential cash flows coming from the sale (or use as collateral) of

    financial assets are added to actual expected cash flows

    Actual cash flows - adjusted to take into account expectedcounterparties behaviour are used in all approaches(not contractual ones)

  • 7/29/2019 8 Liquidity Risk

    15/54

    Stock based approach

    Measures the stock of financial assets that can promptlybe liquidated to face a liquidity shock

    Requires the banks BS be re-stated contribution eachitem gives to creating/hedging funding risks

    Cashable assets (CA) all assets that can quickly beconverted into cash

    Volatile liabilities (VL) short term funds for which there isa risk that they may not be rolled over (wholesale fundingand volatile portion of customer deposits)

    Commitments to lend (CL) OBS items representingirrevocable commitment to issue funds upon request

    Steadily available credit lines (AL) irrevocablecommitments to lend issued to the bank by third parties(usually, other F.I.s)

  • 7/29/2019 8 Liquidity Risk

    16/54

    Stock based approach

    Cashable assets (CA)

    Short-term deposits

    Loans short-term credit lines (e.g., o/n and other interbankfacilities) than can be easily and effectively claimed back

    without endangering the customer relationships Securities only unencumbered positions (not used as

    collateral against loans or derivative contracts) may alsoinclude long term bonds or shares. Does not include securitiesnot traded on a liquid market and not eligible not accepted

    as collateral (e.g., shares in private companies held formerchant banking purposes, unrated bonds, etc.)

    Need of a haircut for: possible loss relative to the market price

    difference between current value and value of the short-term loans that

    could be obtained by pledging them as collateral

    Example of a reclassified B/S

  • 7/29/2019 8 Liquidity Risk

    18/54

    Stock based approach

    Cash Capital Position (CCP)

    Share of cashable assets not absorbed by volatile liabilities

    Signals banks ability to withstand liquidity shortages due to:

    greater-than-expected volatility in funding sources unexpected difficulties in the mgmt of cashable assets

    (e.g. increase haircuts due to unfavourable fin. markets)

    To control for banks size, CCP sometimes scaled by total

    assets

    Example previous slide

    CCP = CA VL = 390 = 9.75% TA

    CCP = CA VL CL = 90 = 2.25% TA

    CCP CA VL CL

  • 7/29/2019 8 Liquidity Risk

    19/54

    Stock based approach

    Long term funding ratios (LTFR) alternative measure ofliquidity based on stocks

    % of assets with a maturity > 5 years funded with

    liabilities with maturity > 5 years or with capital

    Portion of assets with a maturity greater than n years

    which is being funded with liabilities having an equally

    great maturity

    Banks transform ST liabilities into MTL term loans

    LTFR usually below 100%

    Low values (or a deterioration over time) may indicate

    unbalances/weaknesses in the maturity structure of

    assets & liabilities

  • 7/29/2019 8 Liquidity Risk

    20/54

    Cash flow based approach

    CCP based on simplified approach assets and liabilitiesare either stable or unstable (binary approach)

    In reality many different degrees of stability/liquidity exist

    Underlying logic of CF based approaches: restate BS items going beyond a binary logic maturity ladder

    also called mismatch based approach

    Cash flows are sorted across the different maturitiesbased on:

    contractual maturities (including intermediate cash flows)

    banks expectations

    past experience

    Mismatch or liquidity gap (Gt) net unbalance inflowsand outflows

    Example of expected cash flows

    As in the stock-based approaches, demand deposits and loans are dealt with based on

    their expected actual maturity

  • 7/29/2019 8 Liquidity Risk

    22/54

    Cash flow based approach

    Two type of indicators

    Cumulative liquidity gap unbalance between flowsassociated with a given band and all shorter maturities

    Marginal liquidity gaps Gts related to one time band

    Note that, when sorting assets and liabilities across time

    bands, we are considering: cash flows not stocks

    their expected maturity, not their repricing period

    titt GCG

  • 7/29/2019 8 Liquidity Risk

    23/54

    Cash flow based approach

    Negative cumulative liquidity gap bank cannot cover

    foreseeable cash payments with expected inflows

    severe warning of potential liquidity shortage

    However, one weakness cash flows associated with

    securities (including unencumbered assets) are basedon contractual maturities and coupons assets can be

    used as collateral to get new loans, also at a very short

    notice

    re-write the maturity ladder taking into account role ofunencumbered assetsin facing liquidity risks

    Hybrid approach

  • 7/29/2019 8 Liquidity Risk

    24/54

    Hybrid approach

    CF based approach CFs from securities are sorted

    into maturity buckets based on contractual maturity a

    10-year ZC bond face value10 mln entirely associated

    with 10 year band

    Banks treasurer can manage liquidity shortages by

    selling the bond or using it to get funded through a

    collateralised loan or repo

    Haircut funds raised would only be a share (e.g.,

    90%) of the bonds mkt value (which would be less thanface value) e.g. 7 million 70% can be cashed

    quickly, rest (interest and haircut) available in 10 years

    This only applies to unencumbered eligible assets

    assets the bank can freely sell or pledge as collateral

    27/54

    Hybrid approach

    Results achieved so far are affected by

    assumptions on timing and amounts uncertainty

    concerning:

    Amount e.g. floating rate securities, IRS, European options Timing e.g. long-term mortgages being pre-paid, demand

    deposits left with the bank for years

    Both amount and timing cash flows associated to open

    credit lines or commitments to lend

    It is important to consider not only an expected scenario, but

    also check how the liquidity gaps would deteriorate in worst

    case scenarios stress test

  • 7/29/2019 8 Liquidity Risk

    28/54

    Stress test

    Stress test simulation exercise aimed at quantifying the

    effects of an especially adverse scenario

    Three main approaches

    Historical approach historical scenarios (e.g., % of demand deposits

    unexpectedly withdrawn within 2 or 4 weeks) Statistical approach historical data to infer probability distribution of risk

    factors reasonable estimate of potential shocks (e.g., on deposits,

    haircuts, interbank loans, etc.)

    Judgement-based approach subjective appraisals by the banks

    management (support of risk management, supervisors or consultants)

    These approaches can be used to simulate individual risk

    factors separately or jointly (worst case scenarios)

    A. bank run on demand deposits

    B. increase in market volatility increase haircuts on unencumbered assets

    C. A+B jointly

  • 7/29/2019 8 Liquidity Risk

    29/54

    Stress test

    Stressed scenarios are rather intuitive in principle, but theirpractical implementation can prove difficult:1. A stress exercise is usually limited to a number of selected B/S

    items (e.g. effect of an extreme scenario on the time profile of cash

    flows associated only with securities, ignoring other assets andliabilities) a market turmoil may be accompanied by an increasein customer deposits as investors would postpone their assetallocation choices indirect effects should also be included

    2. When more risk factors are considered jointly (e.g., a bank run andan increase in market volatility) a simple algebraic summation of

    their effects may not be correct pessimistic if risk factors are not strongly correlated (probability)

    optimistic., if the two shocks are mutually reinforcing (impact) e.g.confidence crisis hitting a bank in the midst of a market-wide currencycrisis the pressure on deposits might be stronger than it would be ina quiet macroeconomic environment

  • 7/29/2019 8 Liquidity Risk

    30/54

    Contingency funding plans (CFP)

    Stressed scenarios can prove useful in building contingency

    funding plans (CFP) to be triggered in case of extreme scenario

    CFP surveys all possible sources of extra funds in the event of a

    liquidity shock (e.g. temporary withdrawals of compulsory

    reserves, repos with CB, secured or unsecured interbank loans)

    CFP sets priority order (ranking) in which they should be tapped

    cost and flexibility of the sources and type of liquidity shock

    (e.g. interbank loans in case of an institution-specific shock vs.

    intervention of Central Bank in case of a market-wide crisis CFP describes people and structures responsible for

    implementing emergency policies and actions to be taken

    A credible CFP can quickly bring panic under control, limiting

    the duration and breadth of the liquidity shortage

  • 7/29/2019 8 Liquidity Risk

    31/54

    Funding liquidity risk

    Some peculiarities of funding liquidity risk vs other risks

    Liquidity risk not necessarily risk of losses

    Assets & Liabilities mismatch does not need to be faced

    by capital by high quality liquid (unencumbered)assets more capital simply makes a liquidity crisis

    less likely

    If the bank is made up of different legal entities, in the

    event of a liquidity crisis liquid funds cannot freely bemoved from one entity to the other due to the opposition

    of some supervisory authorities

  • 7/29/2019 8 Liquidity Risk

    32/54

    Organizational issues

    Liquidity risk management requires systematic approach with clear

    organizational rules systematic approach also required by Basel

    E.g. Liquidity risk management (LRM)

    LRM policy key role of board of directors

    ensures liquidity risk is correctly identified, measured, monitored andcontrolled

    defines risk tolerance and strategy for liquidity risk management

    identifies roles and responsibilities of the LRM Unit

    receives periodic reports on the liquidity situation

    Examples of periodic reports

    analysis of the flow of funds contingency funding plan

    list of largest providers of funds

    funding gap and maturity structure

    structure and composition of the bank's balance sheet

    size and cost of more recent very short term funding

  • 7/29/2019 8 Liquidity Risk

    33/54

    Organizational issues

    Limits are generally imposed to risk-taking units they may

    refer to different measures examples:

    Max absolute maturity gap

    Max volume of overnight funding in relation to total assets

    Max gap between liquid assets and ST liabilities Min liquid assets net of expected erosion in case of stress

    Max concentration of liabilities across counterparties

    Key role internal audit in LRM process e.g. consistency

    between policies set by senior mgmt and day-by-day risk mgmt,

    adequacy of processes and soundness of measures Often an ALM Committee (ALCO) representatives of all

    business areas that affect liquidity risk responsible for development of specific policies for LRM

    ensuring adequacy of measurement system

  • 7/29/2019 8 Liquidity Risk

    34/54

    Organizational issues

    Liquidity Risk Management unit responsible for:

    identifying liquidity risks incurred by the bank

    monitoring evolution of liquidity profile

    developing policies for controlling and mitigating liquidity risk

    developing appropriate rules for liquidity risk management

    roles,responsibilities and organizational structure; limits; policies and formats for

    reporting to senior management

    Developing liquidity contingency plan

    Early warnings events signalling liquidity shortages in

    advance Internal early warnings e.g. increased concentration of assets orliabilities, increase of assets funded by volatile funding

    External indicators e.g. rating downgrades, decline in the banks stock

    price; increase in the banks CDS spread; increase in the trading volume

    of securities issued by the bank, increase in requests for guarantees,

    increase in the cost of funding, request for (additional) collateral by

    liquidity riskFundamental principle for the mgmt and supervision of liquidity risk 1. A bank is responsible for the sound management of liquidity risk. A

    bank should establish a robust liquidity risk management frameworkthat ensures it maintains sufficient liquidity, including a cushion ofunencumbered, high quality liquid assets, to withstand a range ofstress events, including those involving the loss or impairment of both

    unsecured and secured funding sources.Governance of liquidity risk management

    2: A bank should clearly articulate a liquidity risk tolerance that isappropriate for its business strategy and its role in the financialsystem.

    3: Senior management should develop a strategy, policies and

    practices to manage liquidity risk in accordance with the risk toleranceand to ensure that the bank maintains sufficient liquidity.

    4: A bank should incorporate liquidity costs, benefits and risks in theinternal pricing, performance measurement and new product approvalprocess for all significant business activities (both on- and off-balancesheet)

    and controlling liquidity risk projecting cash flows arising from assets,liabilities and off-balance sheet items

    6: A bank should actively monitor and control liquidity risk and funding needswithin and across legal entities, business lines and currencies

    7: A bank should establish a funding strategy that provides effectivediversification in the sources and tenor of funding.

    8: A bank should actively manage its intraday liquidity positions and risks tomeet payment and settlement obligations on a timely basis under both normaland stressed conditions

    9: A bank should actively manage its collateral positions, differentiatingbetween encumbered and unencumbered assets

    10: A bank should conduct stress tests on a regular basis and use stress testoutcomes to adjust its liquidity risk management strategies, policies, andpositions

    11: A bank should have a formal contingency funding plan (CFP) that clearlysets out the strategies for addressing liquidity shortfalls in emergencysituations

    12: A bank should maintain a cushion of unencumbered, high quality liquidassets to be held as insurance against liquidity stress scenarios

    The role of supervisors 14: Supervisors should regularly perform a comprehensive

    assessment of a banks overall liquidity risk management frameworkand liquidity position

    15: Supervisors should supplement their regular assessments of abanks liquidity risk management framework and liquidity position bymonitoring a combination of internal reports, prudential reports and

    market information 16: Supervisors should intervene to require effective and timely

    remedial action by a bank to address deficiencies in its liquidity riskmanagement processes or liquidity position.

    17: Supervisors should communicate with other supervisors andpublic authorities, to facilitate effective cooperation regarding the

    supervision and oversight of liquidity risk management

    Net cumulative liquidity mismatch position under the

    stress scenario measured at the test horizon

    Cumulative expected cash outflows are calculated by multiplying

    outstanding balances of various categories of liabilities by

    Liquidity risk has been overlooked in the recent past

    As clearly shown by the financial crisis, liquidity risk is

    crucial for individual financial institutions and for the

    stability of the financial system as a whole

    Liquidity risk measurement methodologies are still at an

    initial stage in the financial services industry

    Some indicators are already used by most banks cashcapital position, liquidity gaps, long term funding ratios

    It is more complex to deviate from expected future cash

    flows and take into account stress scenarios

    The regulators are stepping in with some new

    requirements and general principles
