Free markets to Fed markets: How modern monetary policy impacts equity markets
Putnins, Talis J., 2022

Stock markets generally reflect the health and expected future health of the underlying real economy. Explain in what sense did stock markets appear to become disconnected from the real economy during COVID-19. And what were the key drivers of the disconnect?

A

When central banks intervene, positive correlation between the stock market and the future health of the economy breaks down and could even become negative because of the counter cyclicality of the central bank’s actions—expansionary monetary stimulus putting upward pressure on stock prices during periods of deteriorating economic outlook. The increased magnitude of central bank intervention amplifies these effects leading to a greater divergence between stock markets and the real economy.

Free markets to Fed markets: How modern monetary policy impacts equity markets
Putnins, Talis J., 2022

How did large central banks such as the US Federal Reserve respond to falling stock prices during COVID-19 and what are the channels through which the Fed’s actions impacted stock prices?

A

Response of aggressive balance sheet expansion (the FED).
Long-term bond yields: which tend to fall when the Fed buys fixed income securities, reducing the discount rate for equities and increasing stock prices.
The Fed’s actions impact expected future macroeconomic conditions and thereby expected future corporate earnings.

Free markets to Fed markets: How modern monetary policy impacts equity markets
Putnins, Talis J., 2022

In June 2022 global stock markets “crashed” according to market commentators. The key trigger, according to media, is expected actions of the US Central Bank, the Fed. For example, Bloomberg reports “Stock Traders Coming to Grips With a Fed as Baffled as They Are The S&P 500 lost 3.3% to trade at its lowest level since the end of 2020 speaks to the chaos gripping markets of late. The Nasdaq 100 was down 4% Thursday. Bonds, Bitcoin, every sector in the S&P 500 dropped – little was spared”. According to the reading what may have triggered the market crash?

A

???? decline in FED’s BS???

What is the reaction of a stock market to the FED’s balance sheet changes and vis-a-verse?

A

Negative lagged correlation is consistent with the
FED reacting to negative stock returns, or bad
economic outlook by expanding its BS.
Positive correlation being consistent with the idea that the stock market reacts positively to FED’s BS expansion.

Q

Free markets to Fed markets: How modern monetary policy impacts equity markets
Putnins, Talis J., 2022

What are the channels through which the FED’s Asset Purchasing programmes might have impacted the stock market movements?

A

The two major channels:
● Impact on long-term bond yields: FED’s QE in response to the GFC resulted in long-lasting reduction in longer-term interest rates.
● Impact on future health of the economy: QE is likely to have a positive impact on future economic conditions, using wealth effects (QE inflated stock prices), credit channels (lower interest rates i.e. more accessible borrowing).
Additionally, scope of the Asset Purchasing Programme during COVID: if FED has limited itself only to treasury or fixed income markets, their impact on stock markets would be limited to these classes, due to limited spillover effects. However, the FED’s willing to do “Whatever it takes’’ to avoid stock market collapse has signaled it could directly intervene in the market to buy equities (through ETFs). This signal sent by FED may have provided an additional positive shock to equities.

Q

Is there a zero lower bound? The effects of negative policy rates on banks and firms
Altavilla, Carlo, Lorenzo Burlon, Mariassunta Giannetti, and Sarah Holton, 2022

Interest rates are near zero or even well below zero in many countries right now. For example, the ECB key policy rate (deposit facility rate) is negative and current Eurozone yield curve showing negative yields at horizons out to 15 years.
The issues that arise in these circumstances, in particular the concerns that conventional monetary policy may become ineffective, are discussed in the article “Is there a zero lower bound? The effects of negative policy rates on banks and firms”.
Is conventional monetary policy effective when interest rates are below zero - explain the theoretical reasons or arguments why it might or might not be effective. Then discuss the recent evidence about the effectiveness of conventional monetary policy when rates are
negative compared to when rates hover around zero and when rates are positive.

Q

Is there a zero lower bound? The effects of negative policy rates on banks and firms
Altavilla, Carlo, Lorenzo Burlon, Mariassunta Giannetti, and Sarah Holton, 2022

What are the problems of low interest rates?

A

Macroeconomic problems (zero lower bound).
When the interest rates are low and the economy is in liquidity trap (i.e. monetary policy is severely limited), banks cannot lower the deposit rate. If they do so, their clients will just start hoarding (storing for themselves, out of the bank) the paper money. However, this would severely affect banks because big part of their BS comprises of deposits.
Negative interest rate policies
Negative rates reduce banks’ profits and lead banks to reduce lending. However, it could work if there was particular mechanism to increase the costs of hoarding paper currency.

What “liquidity trap”?

A

A liquidity trap is an adverse economic situation that can occur when consumers and investors hoard cash rather than spending or investing it even when interest rates are low.

Q

Is there a zero lower bound? The effects of negative policy rates on banks and firms
Altavilla, Carlo, Lorenzo Burlon, Mariassunta Giannetti, and Sarah Holton, 2022

Is is unclear how and which investors are affected by negative interest rate environment. How do the effects vary if the rate cut happens above, around and under the ZLB?

A

When the cut is happening and rates still remain above the ZLB, banks pass on most of the policy rate cuts within 12 months.
When the cut is happening and rates still remain around ZLB, there is little pass through even after a year of only 20% of the original cut is reflected. This supports hard ZLB - concentration around 0%.
When cut happens and rates pass the ZLB, pass through
increases but only for financial sound banks. ZLB stops being temporary policy.

Is there a zero lower bound? The effects of negative policy rates on banks and firms
Altavilla, Carlo, Lorenzo Burlon, Mariassunta Giannetti, and Sarah Holton, 2022

A

Safe banks, may have particularly strong market power when weak economies require NIRP. This is because firms often deposit the cash in banks whose deposits have high ratings => firms have a demand for safe assets.
Due to such market power, on average the banks in non-stressed countries are more likely to charge
negative rates on corporate deposits.

How does the excess liquidity affect banks’ profits when interest rate drops?

A

The profits of banks with high excess liquidity are more negatively affected when the interest rate drops, as these banks are more likely to impose negative rates.

A

!!!!!wtf

Deposit growth is higher after banks start imposing negative rates on deposits. And weak banks experience lower deposit growth in the first months.

Q

Is there a zero lower bound? The effects of negative policy rates on banks and firms
Altavilla, Carlo, Lorenzo Burlon, Mariassunta Giannetti, and Sarah Holton, 2022

A

Corporate channel of monetary policy
Since negative rates increase the cost of holding cash, this discourages the corporate savings glut. Ultimately, the firms rebalance their assets and spend cash to expand their investments i.e. promote economic growth.
Firms associated with banks who charge negative rates and are more exposed to negative rates via higher liquidity experience higher fixed asset growth and decrease in liquidity. The effect is even stronger for smaller firms, as they highly rely on the relationship with bank for credit.
● Firms with high liquidity experience a small drop in profitability in the year in which their bank starts to charge negative rates, they increase investment and the investments start to pay off. Before NIRP firms hoarded liquidity and applied too high discount rates to investment.

Q

Is there a zero lower bound? The effects of negative policy rates on banks and firms
Altavilla, Carlo, Lorenzo Burlon, Mariassunta Giannetti, and Sarah Holton, 2022

How does the effect of lowered interest rates offset itself?

A

Banks are more profitable and could lend more.
Banks do lend more due because cheaper lending promoted firms to borrow more. Hence, the boosted
economy offsets the negative effects of NIRP that is decreased intermediation margins.

29
Q

Is there a zero lower bound? The effects of negative policy rates on banks and firms
Altavilla, Carlo, Lorenzo Burlon, Mariassunta Giannetti, and Sarah Holton, 2022

A

There is a finding that effects of the NIRP on the economy are stronger if the banks are healthy and can charge negative rates on deposits. Hence, the mechanisms aiming to preserve banks’ profitability and intermediation capacity in periods of negative rates may therefore be particularly desirable.

Q

Exchange-traded funds 101 for economists
Lettau, Martin, and Ananth Madhavan, 2018

ETFs have grown tremendously during the past decade and during the recent COVID-19 turmoil in markets they accounted for 30-40% of total trading volume in some markets.
(i) Why are ETFs popular among investors? What are their attractive features?
(ii) Explain the role of an authorized participant in ETFs?
(iii) Explain the “liquidity mismatch” concern relating to ETFs.

A

Authorized participants are typically large firms who can access the capital markets and bring commodities to ETFs.
“Liquidity mismatch” measures the mismatch between the market liquidity of assets and the funding liquidity of liabilities, at a firm level.

ETFs have grown substantially during the past decade. The authors propose several concerns and misconceptions around the ETFs.
(i) What are the concerns? Explain.
(ii) What impact are ETFs having on traditional active mutual funds? You may draw on materials discussed in lectures or other sources.

A

Flash crash, closure of ETF, short selling of ETF….

32
Q

Exchange-traded funds 101 for economists

33
Q

Exchange-traded funds 101 for economists
Lettau, Martin, and Ananth Madhavan, 2018

What is the difference between ETFs and mutual funds regarding interaction with capital markets?

A

ETFs do interact through authorized participants, mutual funds interact directly with capital markets.

34
Q

Exchange-traded funds 101 for economists
Lettau, Martin, and Ananth Madhavan, 2018

How are the trades of ETF happening? How is the ETF share price determined? What about transaction costs?

A

● Investors mostly do not trade the fund directly. Instead, they trade on an exchange or with Authorized
Participants.
● Although shares of ETFs can be created/redeemed at the end of trading day, the Authorized Participants will
typically lock in any profits intraday (ex. to eliminate
arbitrage opportunity).
● Trades occur at a market determined price. Externalized i.e. net selling does not require ETF manager to interact with capital market.
● Greater transparency because activity is listed; Holding are the intraday trading also listed and ETF’s
investment strategy are specified in advance
● Investors can short shares, lend shares or buy on
margin.

35
Q

Exchange-traded funds 101 for economists
Lettau, Martin, and Ananth Madhavan, 2018

How are the trades of mutual fund happening? How is the mutual funds’ share price determined? What about transaction costs?

A

● Investors trade with the fund directly. Hence, there is no counterparty needed
● Trades occur at the end of the day and at net asset value
● Remaining investors in the fund bear the transaction
costs incurred by participants who remeed or subscribed.
● Holding are listed quarterly
● Investors cannot short shares, lend shares or buy on margin.

36
Q

Exchange-traded funds 101 for economists
Lettau, Martin, and Ananth Madhavan, 2018

What are the types of ETFs?

A

EQUITY ETFs
● Market cap based ETFs
● Sector ETFs: track market-weighted capitalization benchmark for a sector (e.g. real estate)
● Factor/Smart driven by
beta ETFs: desire to outperform the market by focusing on certain factors linked to stock returns (e.g. size factor). It is a cross between active and passive investment strategies
FIXED INCOME ETFs
Initially, investment government portfolios grade of and bonds. Recently, bond ETFs have been created based on bank loans and high-yield bonds The market of FI ETFs has been growing because:
● Bond ETFs are traded on exchange transparency spreads
● Higher (bid-ask available)
COMMODITY ETFs
Are viewed as a hedge against inflation or a source of diversification in the portfolio.

37
Q

Exchange-traded funds 101 for economists
Lettau, Martin, and Ananth Madhavan, 2018

What are the potential problems with ETFs?

A

● Investors may have poor financial knowledge to distinguish between the types of ETFs.
● Intraday liquidity can cause “too much” trading. Investors who trade actively in stocks suffer lower returns than those who trade less.
● The proliferation of indices, some custom and others concentrated. Asset managers may create indices that are designed to do well in backtesting but might not
do well going forward.

38
Q

Exchange-traded funds 101 for economists
Lettau, Martin, and Ananth Madhavan, 2018

A

● Closure of ETFs
When the ETF closes, its price should converge to its NAV and underlying assets may be returned.
● Short selling of ETFs
May cause bankruptcy of the fund if the aggregate long and synthetic long positions exceeds the total actual number of outstanding ETF shares.
● Securities lending by ETFs
May pose a threat to investors but it is very unlikely due to the presence of different safeguards on lending of securities by ETFs. Moreover, it enhances short-selling → improved price liquidity and efficiency.
● Flash Crash
ETFs were represented among the securities most affected with prices diverging from their NAVs – could cause the Flash Crash, yet most likely flash events are not driven by structural problems with ETFs (e.g. a lot of trading venues, fragmented market).
● Liquidity Mismatch
Liquidity in the primary market refers to the ability of Authorized Participants (APs) to acquire the underlying assets and transfer them to the ETF. The chance that an AP steps away in a crisis may pose systematic risk. Yet, if
a particular AP stops its activities, remaining APs continue providing liquidity → can be a problem only for small ETFs which have few APs.
● Impact on underlying markets
○ Index trackers are typically based on market capitalization weighted schemes → pricing errors in underlying stocks might feed on themselves
○ Index funds are price-takers, not price-makers
○ The impact of a “basket” security on liquidity and distortion of prices of the underlying market is
unclear

Q

Decentralized finance: On blockchain-and smart contract-based financial markets
Schär, F., 2021

What is decentralized finance (DeFi)?

A

An alternative financial infrastructure built on top of the
Ethereum blockchain. In general, this architecture can create an immutable and highly interoperable financial system with unprecedented transparency, equal access rights, and little need for custodians, central clearing houses, or escrow services, as most of these roles can be assumed by “smart contracts”.

40
Q

Decentralized finance: On blockchain-and smart contract-based financial markets
Schär, F., 2021

What is a smart contract?

A

A small applications stored on a blockchain and executed in parallel by a large set of validators. Executed as specified and allow anyone to verify the resulting state changes independently – provides security.
Regular server-based applications: cannot observe internal logic, user is not in control of
execution environment – leads to risks
● Counterparty risks are eliminated, since in order to start the process certain conditions need to be satisfied on both sides – no need for custodian
● Smart contracts on one Blockchain (the vast majority is on Ethereum) provide composability – easy to build new processes based on existing ones

41
Q

Decentralized finance: On blockchain-and smart contract-based financial markets
Schär, F., 2021

What is tokenization?

A

A process of adding new assets to a blockchain. Tokenised assets are more efficient – much easier and faster to transfer them. Most prominent type - stablecoins (track a real-world asset/commodity).

42
Q

Decentralized finance: On blockchain-and smart contract-based financial markets
Schär, F., 2021

What kind of collaterals (of tokens) there appear?

A

Three types of collateral: off-chain collateral, on-chain collateral, and no collateral
● Off-chain – self explanatory, assets in the boring physical world
● On-chain – most transparent, lock native blockchain assets, assets at a certain ratio to the token value; Dai token – lock 150 USD in Ether and get 100 USD-tracking tokens
● No collateral – pure vibes (and maybe fraud)
● Other types of tokens: NFTs, governance tokens, commodity-tracking assets etc.

43
Q

Decentralized finance: On blockchain-and smart contract-based financial markets
Schär, F., 2021

What are the differences between centralized and decentralized exchanges?

A

Centralised exchange implies transferring your crypto to an account on that exchange, kind of defeating the whole purpose and value proposition of crypto, yet remains the most popular due to lower costs
Decentralised exchange, on the contrary, allows one to be in control of their own assets until the trade is executed.

44
Q

Decentralized finance: On blockchain-and smart contract-based financial markets
Schär, F., 2021

What are the types of decentralized exchanges?

A
  1. Decentralized Order Book Exchanges: use smart contracts to execute trades between two individual parties. This type is further divided into on-chain and offchain.
  2. Constant Function Market Maker (CFMM): smart contract-liquidity pool that holds (at least) two crypto assets in reserve and allows anyone to deposit tokens of one type and thereby to withdraw tokens of the other type
  3. Smart Contract-Based Reserve Aggregation: gives user a chance to get the best deal among various liquidity providers using a smart contract automatically choosing the best exchange rate
  4. Peer-to-Peer Protocols: are simply two-party agreements to exchange a pair of assets
45
Q

Decentralized finance: On blockchain-and smart contract-based financial markets
Schär, F., 2021

What are flash loans?

A

The borrower receives the funds, uses, and repays them— all within the same blockchain transaction. If the funds are not returned by due date, the loan is cancelled, and assets come back to the lender.

46
Q

Decentralized finance: On blockchain-and smart contract-based financial markets
Schär, F., 2021

What are the advantages of decentralized lending platforms?

A

It allows both the lender and the borrower of the loan to remain anonymous and this does not lead to counterparty risk, thanks to smart contracts or collateral.

47
Q

Decentralized finance: On blockchain-and smart contract-based financial markets
Schär, F., 2021

What are other options of lending in decentralized market?

A
  1. Collateralized Debt Positions – a user can create new tokens by locking cryptoassets in a smart contract; the user is then able to receive a stability fee – interest rate set by the community
  2. Collateralized Debt Markets – a simpler option where a user can borrow existing cryptoassets from another user, while locking the collateral in a smart contract (this one is arguably less smart)
48
Q

Decentralized finance: On blockchain-and smart contract-based financial markets
Schär, F., 2021

What are decetralized derivatives?

A

Decentralized derivatives are tokens that derive their value from an underlying asset’s performance, the outcome of an event, or the development of any other observable variable.
There are two types:
1. Asset-Based Derivative Tokens – synthetic tokens that are tied to a wide variety of real-world assets (e.g., USD, gold, maybe Latvenergo stock)
2. Event-Based Derivative Tokens – tokens that can be based on any objectively observable variable with a known set of potential outcomes, a specified observation time, and a resolution source. A complete set of sub-tokens consists of 1 sub-token for each potential outcome. These sub-tokens can be traded individually, the price of each should reflect the priced-in probability.

49
Q

Decentralized finance: On blockchain-and smart contract-based financial markets
Schär, F., 2021

What are oracles?

A

Compex systems that connect the boring off-chain events to the exciting on-chain world required by decentralized derivatives.

50
Q

Decentralized finance: On blockchain-and smart contract-based financial markets
Schär, F., 2021

What opportunities does DeFi provide?

A

● Efficiency – DeFi relies on smart contracts (no need for a third party in transactions and transfers, token transfers are faster than any of the transfers in the traditional financial system).
● Transparency - DeFi applications are transparent. All transactions are publicly observable, and the smart contract code can be analysed on-chain.
● Accessibility - DeFi protocols can be used by anyone, the risk of discrimination is almost inexistent due to the lack of identities.
● Composability – DeFi protocols are like lego, one can stack something new on top almost indefinitely, creating new, hopefully useful, processes.

51
Q

Decentralized finance: On blockchain-and smart contract-based financial markets
Schär, F., 2021

What risks does DeFi provide?

A

● Smart Contract Execution – coding errors can deem the whole system vulnerable. Since average users cannot check the security of a given contract code.
● Operational Security – many DeFi protocols and applications use admin keys that allow to change the contracts. Might be stored insecurely.
● Dependencies – if one block in a complex smart contract structure fails, everything built on top becomes virtually useless.
● External Data - the so-called oracles (data from outside) introduce dependencies and may, in some cases, lead to heavily centralized contract execution.
● Illicit Activity - cryptoassets may be used by individuals who want to avoid records and monitoring.
● Scalability – Blockchains face the ultimate trade-off between decentralization, security and scalability.

○ CAPM betas are sizeable but statistically significant only for Fama French 5- and 6- factor models
○ Alphas are large and statistically significant for all models (including CAPM, 3- and 4-factor models)
○ Cryptos had negative and significant exposure to HML – crypto currencies comove with growth rather than value stocks
○ Authors look at 155 other factors documented in the finance literature and find no discernible patterns of loadings

Is there any evidence that cryptocurrencies might be exposed to other commodities or economic factors?

A

No.
○ Precious metal commodities (expect for ETH which positively and significantly exposed to Gold)
○ Macroeconomic factors (except for ETH which has negative and significant loading on durable
consumption growth factor)

A

● Significant and positive time-series momentum
1 standard deviation increase in current day’s bitcoin return predicts 0.33% increase in daily return the
next day. Daily returns also significantly predict 1,3,5 and 6 days ahead returns.
1s.d. increase in Bitcoin’s weekly return predicts a 3.16% increase in next week’s return; weekly returns
statistically significantly predicts 1,2, 3 and 4-week ahead returns
For Ethereum the momentum effect is less significant

A

● No predictive power for “price to “dividend” “proxy.
There are no dividends in Bitcoin. However, the author uses the amount of Bitcoin wallet users as a proxy.
● Weak Relationship with realized volatility. Realized volatility also does not predict returns of Bitcoin and Ethereum. Though it predicts Ripple returns at 4, 5 and 7-day ahead frequencies.

Why the crypto universe is unsuitable as the basis for a monetary system?

A

Because of structural flaws: it lacks a stable nominal anchor, while limits to its scalability result in fragmentation.

What are the three features of DeFi that can potentially improve the current financial system?

A
  1. Programmability – this concept refers to the ability of smart contracts to automate certain actions. This can eliminate the middle man in different processes (e.g., lending, borrowing, paying taxes (no more fraud ))
  2. Composability - the capacity to combine different components in a system, which would allow to create complex multi-layered monetary system processes.
  3. Tokenization – “tokenised” assets can be exchanged much quicker and efficient, utilizing the blockchain system.
    ● In addition, the borderless nature of crypto allows for faster and safer cross-border transactions

Q

The future monetary system
Bank of International Settlements (BIS), 2022

What are the flaws of cryptocurrencies?

A

● The crypto sector in its current form cannot fulfil all the high-level goals of a digital monetary system
● One of the main issues is the security decentralization scalability trilemma, as it is impossible to scale as fast maintaining the security and decentralization
● This led to fragmentation, as new blockchains cut corners on security
● There is a lack of nominal anchor, with crypto having to borrow it off-chain from real-world currencies
● There is a tendency to centralization (ironic) in crypto, with a lot of decisions made through governance tokens with centralised control and most of the trading occurring on centralised exchanges. With weak regulation, it creates significant risks of rug pulling or unprofessionalism
● These flaws would persist even if regulation and oversight were to address the financial instability problems and risk of loss implicit in crypto

64
Q

The future monetary system
Bank of International Settlements (BIS), 2022

What is the role of CB in pictured in the future?

A

The future monetary system should meld new technological capabilities with a superior representation of central bank money at its core
1. Central banks are uniquely positioned to provide the core of the future monetary system, as one of their fundamental roles is to issue central bank money (M0)
2. To provide the means for the ultimate finality of payments by using its balance sheet
3. To support the smooth functioning of the payment system by providing sufficient liquidity for settlement
4. To safeguard the integrity of the payment system through regulation, supervision and oversight

Q

The future monetary system
Bank of International Settlements (BIS), 2022

The common theme is that decentralisation can be achieved without the structural flaws of crypto. What are the roles in future monetary system?

A

●The division of roles between the central bank – which
provides the foundations of the system – and private sector entities that conduct the customer facing activities
● On top of this traditional division of labour come new standards such as application programming interfaces to ensure programmability, composability and tokenisation
● CBs can utilise permissioned (as opposed to permissionless in blockchain) distributed ledger
technology to create central bank digital currencies (CBDCs) that can streamline a wide array of innovations - multi-CBDC arrangements, much wider range of financial intermediaries (not just commercial banks, interoperability between customer-facing platforms provided by intermediaries, instant payments, inclusive design, verification through zero-knowledge proofs etc.)
