Q

Convexity

A
  • For large changes in yield: % price change not the same for increases vs. decreases in yield.
    o % price increase > % price decrease
    o “convexity adjustment needed for accurate estimate in price changes

Q

o On balance Sheet hedging (Liability Sensitive Banks)

A

 Shorten its assets, use more variable rate loans, lengthen its liabilities, use more fixed-rate liabilities.
 Banks might not want shorter term assets, or longer term liabilities because they would affect the banks liabilities.

Q

Future Markets and Contracts:

A
  • Similar to forwards:
    o Deliverable or cash settlements
    o Contract valued at 0 at the time it is created.
  • Differences:
    o Futures trade on organized exchanges, forwards are private and do not trade
    o Futures, are marked to market; contract price adjusted each day
    o Highly standardized vs customized forward contracts
    o A single clearinghouse is the counterparty to all futures contracts; forwards are contracts with the originating counterparty
    o The government regulates futures markets; forward contracts are not regulated.

Q

Basis Risk:

A
  • Spot bonds and futures on bonds are traded in different markets.
  • The shift in yields, ∆𝑅 (1+𝑅) , affecting the values of the on-balance sheet cash portfolio may differ from the shift in yields, ∆𝑅𝐹 1+𝑅𝐹 , affecting the value of the underlying bond in the futures contract.
  • Changes in spot and futures prices or values are not perfectly correlated; this lack of perfect correlation is called basis risk.
  • Basis = cash market price – futures market price

Q

How Investors Use CMOs

A
  • Investors who want longer term, more predictable cash flows will invest in C tranches.
  • Investors who want shorter term investments, and can live with some cash flow volatility, will invest in A tranches.
  • Higher tranches get lower coupon rates and less credit risk because they are paid off earlier

Q
  • Tranche x:
A

These investors get no coupon, and they get paid off last. They are exposed to the most credit risk.
o These investors have a special upside: They receive all remaining principal and interest cash flows after other tranches are paid off.
o This is called the “equity tranche.“ These investors benefit if the MBS pool contains fewer than expected loan defaults

Q

Credit default swap (CDS):

A

the most popular instrument used to mitigate credit risk; the CDS is similar to an insurance contract whereby the protection buyer makes premium payments to the protection seller in exchange for a contingent payoff in default or other credit event.

47
Q

CDS Contract

A
  • Protection seller receives periodic (e.g., quarterly) cash flow if the bond issuer has no credit event.
  • Protection seller suffers a loss (cash outflow) in case of credit event (e.g., bankruptcy of the bond issuer)
  • Protection seller receives a stream of cash flows that are similar to cash flows of the underlying bond.
48
Q

Synthetic Bond

A

Selling CDS protection + buying Treasuries (or other risk-free assets).

49
Q

Uses of CDSs

A
  • From buyer’s perspective:
    o Hedge against credit risk
    o Short (credit risk of) the underlying entities
  • From protection seller’ perspective
    o Long (credit risk of) the underlying entities
    o Create synthetic bonds/CMOs.
50
Q

Short

A

Sell Position. Sell now, buy later. Lock in a sale at the current rates.

51
Q

Long

A

Buy Position. Buy now, sell later. Lock in a buy at the current rates.

52
Q

CDS vs Insurance

A
  • CDS is considered insurance against non-payment.
  • Difference: Protection buyer in CDS does not need to hold the reference entity but can still collect payouts without risking actual loss from investments in the reference entity.
  • Light regulation, seller is not required to hold reserves to cover payouts.
53
Q

CDS Market:

A
  • CDS first introduced in early 1990s to help hedge credit risk in connection with their lending activities.
  • CDS was gradually extended to cover sovereign debt, corp. debt and MBS.
  • In the early 2000s, the credit default swap on a basket of reference entities (multi-name CDS, CDS index) was introduced into the market.
  • The CDS market experienced an enormous growth after the ISDA standardized the documentation for credit default swaps in 1999 until the 2008-09 crisis.
54
Q

CDS Market Participants:

A
  • Commercial banks: protection buyer/seller, mostly hedging
  • Investment banks: broker/dealer, hedging/speculating
  • Hedge funds: hedging/speculating
  • Insurance Companies: mostly protection seller
  • Mutual Funds: hedging/speculating
55
Q

Benefits of using CDSs:

A
  • Reduced transaction costs:
    o Do not include funding
    o No covenants, coupons, call provisions, etc.
    o Demand for the CDSs is bigger than for underlying bonds, because more participants in the CDS market.
  • Expanded investment scope: CDS investors can still get exposure to a bond issuer even if its bonds are not available (or are prohibitively expensive) on the bond market
  • Embedded leverage effect: the initial cost of selling CDS protection on a bond is usually a fraction of the cost of buying the bond outright.
  • Better utilization of information: CDSs enable investor to “short” bonds more easily
56
Q

Issues created by CDS

A
  • Empty creditor problem:
  • Transmit and amplify financial market shocks
    o Low transparency in the OTC market, hard to ascertain counterparty risk.
    o Concentrated counterparty risk: G14 brokers/dealers.
    o “Insurance is only as good as the insurer.”
    o “Run” on counterparty can occur in an interwoven and informationally opaque system.
57
Q

Liability Side Liquidity Risks

A

o Bank suffers temp. shortage of cash due to larger than exp. Deposit withdrawals. Caused by:
 Increase in interest rates on competing investments
 Sudden lack of trust in the financial condition of the bank, causes a “run” on the bank.

58
Q

Asset Side Liquidity Risks

A

o Bank suffers temp. shortage of cash due to larger than exp. Draw-downs of credit lines. Could be caused by:
 General economic or sector-specific slowdown that increases firms’ need for credit.

59
Q

Managing Liability-side Liquidity Risk

A
Options:
Use equity as cash buffer
Fire sale of loans at lower than long term prices
Purchase from the fed funds market
Borrow at the fed's discount window
  -Short Term solutions
60
Q

Managing Asset-side Liquidity Risk

A
Options:

Use equity as a cash buffer
Purchase from the fed funds market
Borrow at the fed's discount window
  - Short Term solutions
61
Q

“Natural Hedge” against liquidity risk

A

o During recessions, deposits flow into banks due to a flight to quality. (Bank liquidity increases.)
o These deposit inflows occur just as business firms begin to draw down their lines of credit.
o Hence, there is a “natural hedge” against liquidity risk embedded in the structure of banks.

62
Q

Managing Liquidity Risk on Balance Sheet

A

Stored liquidity
Core Deposit funding
Purchased liquidity

63
Q

Stored Liquidity

A

Hold large amounts of cash and liquid securities as a buffer. High opportunity costs: Banks make fewer loans.

64
Q

Core Deposit Funding

A

o Core deposits are more stable and less likely to be withdrawn, but develop only slowly over time since bank-depositor relationship should be created

65
Q

Purchased Liquidity

A

o Funds from other institutions: buy fed funds, sell repos, or use the discount window
o Short term fixes, which become increasingly expensive until the bank’s resources are exhausted.

66
Q

Public Policies that reduce liquidity risk

A
-	Deposit insurance (FDIC) 
o	Created a class of deposits that are unlikely to run even if the bank is rumored to be (or actually is) in financial trouble. 
-	Discount window (Fed) 
o	Provides a short-run stop-gap for banks that have too few deposits to fund their lending obligations.
67
Q

Net Liquidity

A

Sources of Liquidity - Uses of Liquidity
- Should never be negative:
o Actual borrowing should not exist beyond the limit and discount windows must be collateralized with treasury securities
- Tracked daily

68
Q

Sources of Liquidity

A

Cash, excess reserves at the fed, liquid securities, short-run borrowing limit

69
Q

Uses of liquidity

A

Short-run borrowing against the limit (fed funds, repos), Discount window loans (from the Fed)

70
Q

Financing Gap

A
  • Average Loans – Core Deposits
    o Often expressed as a ratio:
     Loans-to-core deposits ratio = average loans/ core deposits
71
Q

Average Loans

A

Loan balances over past month or quarter

72
Q

Core Deposits

A

Stable deposit balances

73
Q

Positive Financing Gap

A

 Positive = low liquidity, poor management, strong lending opportunities

74
Q

Negative Financing Gap

A

 Negative = high liquidity, careful/conservative management and relatively poor lending opportunities

75
Q

If loans grow quickly (Gap >0)

A

bank must fund them until new core deposits can be raised. Options: Draw down liquid assets or use short-run borrowing capacity. Return on assets increases, but liquidity position deteriorates.

76
Q

If Loans grow slowly (Gap<0)

A

bank must invest new deposits until new lending opportunities arise: Invest in low-yielding cash or liquid securities. Liquidity position improves, but return on assets declines.

77
Q

Liquidity Index:

A
  • a measure of the potential losses a bank could suffer as the result of a sudden disposal of assets.
78
Q

High Liquidation Value

A
  • Cash has a “liquidation value” (ratio in the formula) of 100%
  • Treasuries also have an extremely high liquidation value
79
Q

Low Liquidation Value

A
  • Loans have lower values:
    o Syndicated loans: only a small fire sale discounts
    o Loans to middle-market firms: large fire sale discounts
    o Loans to small, local businesses: very large fire sale discounts
    o Collateralized loans will have smaller discounts, all else equal
80
Q

BASEL III Liquidity Proposal

A

o May distort true solvency position, Greater discretion in loan loss recognition and write-downs or the impact of such losses on capital, Most commonly used by regulators.

84
Q

Problems with Capital to Asset Ratio

A

  • Unclear about risk weights across 5 categories and why they were chosen, doesn’t consider loan portfolio diversification opportunities, may reduce incentive for banks to make commercial loans, do not account for interest rate or liquidity risk.
102
Q

o Tier 1 Leverage Ratio:

A

Tier 1 Capital/ Assets

103
Q
  • Prompt Corrective Action:
A
  • In 1991, Federal Deposit Insurance Corporation Improvement Act (FDICIA) directed U.S. supervisors to take Prompt Corrective Action (PCA) if banks’ capital ratios fell below “adequately capitalized”
    o The primary regulatory influence over bank capital levels.
    o Implement more severe supervision as a bank’s capital declines.
    o Resolve banking problems at an early stage and at the least possible cost to the bank insurance fund.
104
Q

Basel II Bank Capital Regulation

A
  • 2004, the Basel Committee met again and devised the new BASEL Accord. These new standards included:
    o An “internal ratings-based” (IRB) approach for more sophisticated banks.
    o A framework for considering risks other than credit risk.
    o “Three-pillar” Concept
105
Q

Pillar I

A

Calculation of regulatory minimum capital requirement (1. Credit Risk 2. Market Risk 3. Operational Risk)
Standardized vs Internal Ratings based approach

106
Q

Pillar II

A

Regulatory supervisory review

107
Q

Pillar III

A

Requirements on rules for disclosure of capital structure, risk exposures, and capital adequacy.

Q

Basel III Capital Proposals for Reform

A
  • Quality, consistency, and transparency of the capital base is raised:
    o Predominant form of Tier 1 Capital must be common share and retained earnings.
    o Criteria for Tier2 capital will be tightened
  • Risk coverage will be strengthened:
    o More integrated management of market and counterparty credit risk.
    o Adding capital charges due to deterioration in counterparty’s credit rating.
  • Leverage ratio will be introduced:
    o Supplementary measure to the risk-based framework, put a floor to the build-up of leverage
  • Pro-cyclical capital standards is proposed:
    o Measures to address pro-cyclicality.
    o Banks would build up capital buffers during good times while holding less during bad times.
109
Q

Basel III – Liquidity Proposals

A
  • The liquidity coverage ratio (LCR)
  • The Net Stable Funding Ratio (NSFR)
  • Banks that rely too heavily on short-term wholesale funding or do not hold sufficient high quality liquid assets will face high cost of adjustments to meet these new minimum ratios.
110
Q
  • The liquidity coverage ratio (LCR)
A

o High Quality Liquid Assets / 30-day Net Cash Outflows >/= 100%
o To ensure banks always have a 30-day liquidity buffer for emergency situations.

111
Q

 High quality liquid assets

A

cash, central bank reserves, high-quality marketable securities

112
Q

 Net cash outflows:

A

stable deposits – less stable deposits – unsecured wholesale funding

113
Q
  • The Net Stable Funding Ratio (NSFR)
A

o Available Stable Funding / Required Stable Funding >/= 100% ~ (Stable Core Deposits/Medium And Long-term Loans >/= 100%)
o To ensure that banks hold sufficient stable funding to match their medium and long-term lending.

114
Q

Shortcomings of R GAP

A

Interest rates unlikely to change by same amount for assets and
liabilities (a constant “spread” is unlikely).
o Interest rate unlikely to change by same amount for all accounts
within the 1-year maturity bucket.
o A book-value method; but market values of assets and liabilities
change with interest rates.
o Deposits can run-off when rates increase (not measured).
o Loans can pre-pay when rates decrease (not measured).
o Ignores interest rate effects on assets and liabilities with longer
remaining maturities.
o Ignores interest rate effects on off-balance sheet activities (e.g.,
interest rate swaps, unused lines of credit).
