Wall Street’s main indexes registered marginal gains and the benchmark 10-year US Treasury bond retreated slightly below 4.3% on Tuesday. In the European morning, US stock index futures modestly lower and the 10-year yield moves sideways near 4.29%. The Fed is widely expected to leave the policy rate unchanged following the March meeting. Investors will scrutinize the dot plot for hints at the timing of the policy pivot and the total amount of rate reduction policymakers are forecasting for this year.

Fed Preview: Forecasts from 15 major banks, risk of a hawkish shift in the dot plot.

The UK’s Office for National Statistics reported early Wednesday that inflation, as measured by the change in the Consumer Price Index (CPI), declined to 3.4% on a yearly basis in February from 4% in January. Other details of the report showed that the annual Retail Price Index increased 4.5% as forecast, while the Producer Price Index – Input decreased 2.7%. GBP/USD holds steady slightly above 1.2700 after these data.

Breaking: UK CPI inflation softens to 3.4% in February vs. 3.6% expected.

USD/JPY rose sharply and gained more than 1% on Tuesday following the Bank of Japan’s (BoJ) monetary policy announcements. The pair preserves its bullish momentum early Wednesday and was last seen trading at its highest level since November above 151.50.

Japanese Yen adds to post-BoJ losses, approaches multi-decade low ahead of Fed.

NZD/USD lost more than 0.5% on Tuesday and touched its lowest level in nearly four months near 0.6030. The pair struggles to stage a rebound and was last seen trading modestly lower on the day at around 0.6050. Statistics New Zealand will publish fourth-quarter Gross Domestic Product (GDP) data in the early trading hours of the Asian session.

EUR/USD erased its daily losses after dropping below 1.0850 and closed the day virtually unchanged on Tuesday. The European economic docket will feature Construction Output data for January. During the European trading hours, European Central Bank (ECB) President Christine Lagarde will deliver a speech at the ECB and Its Watchers conference in Frankfurt.

Gold extended its sideways grind and posted small losses on Tuesday. XAU/USD continues to move up and down in a relatively tight range between $2,150 and $2,160 midweek.

Gold price extends the range play above $2,150 level ahead of the key FOMC decision.

 

Fed FAQs

Monetary policy in the US is shaped by the Federal Reserve (Fed). The Fed has two mandates: to achieve price stability and foster full employment. Its primary tool to achieve these goals is by adjusting interest rates. When prices are rising too quickly and inflation is above the Fed’s 2% target, it raises interest rates, increasing borrowing costs throughout the economy. This results in a stronger US Dollar (USD) as it makes the US a more attractive place for international investors to park their money. When inflation falls below 2% or the Unemployment Rate is too high, the Fed may lower interest rates to encourage borrowing, which weighs on the Greenback.

The Federal Reserve (Fed) holds eight policy meetings a year, where the Federal Open Market Committee (FOMC) assesses economic conditions and makes monetary policy decisions. The FOMC is attended by twelve Fed officials – the seven members of the Board of Governors, the president of the Federal Reserve Bank of New York, and four of the remaining eleven regional Reserve Bank presidents, who serve one-year terms on a rotating basis.

In extreme situations, the Federal Reserve may resort to a policy named Quantitative Easing (QE). QE is the process by which the Fed substantially increases the flow of credit in a stuck financial system. It is a non-standard policy measure used during crises or when inflation is extremely low. It was the Fed’s weapon of choice during the Great Financial Crisis in 2008. It involves the Fed printing more Dollars and using them to buy high grade bonds from financial institutions. QE usually weakens the US Dollar.

Quantitative tightening (QT) is the reverse process of QE, whereby the Federal Reserve stops buying bonds from financial institutions and does not reinvest the principal from the bonds it holds maturing, to purchase new bonds. It is usually positive for the value of the US Dollar.

Decentralized Finance (DeFi) offers a captivating landscape teeming with potential for investors seeking high ROI. However, navigating this dynamic ecosystem necessitates a comprehensive understanding of its underlying principles and functionalities. Unlike traditional finance, DeFi operates on a peer-to-peer basis, eliminating the need for intermediaries like banks.

SCORP will launch on April 15th!

This fosters greater accessibility and transparency and introduces inherent risks associated with smart contract vulnerabilities and market volatility. Astute investors must carefully assess DeFi projects to identify those boasting robust utility, sustainable growth models, and a commitment to user security.

This analysis delves into three distinct DeFi players, Scorpion Casino (SCORP), Polygon (MATIC), and Uniswap (UNI), to illuminate their unique value propositions and potential impact on investor portfolios. By meticulously dissecting these projects, we aim to empower investors to make informed decisions as they explore DeFi’s exciting possibilities.

SCROP GameFi Experts Rocking Presale

Scorpion Casino’s presale has garnered significant attention, exceeding $7.5 million in raised capital. This impressive feat underscores the project’s strong market appeal and positions SCORP as one of the top altcoins to consider. Scorpion Casino’s allure stems from its comprehensive GameFi ecosystem, boasting a diverse offering of over 210 casino games and numerous betting options.

The announcement of an upcoming exchange listing on March 25th further amplifies the presale’s success. This strategic move broadens Scorpion Casino’s reach and accessibility, making it an even more attractive option for DeFi investors seeking lucrative presale opportunities.

Crude Oil News Today: Gains Capped by Profit-Taking as Dollar Strengthens

By |2024-03-20T11:43:51+02:00March 20, 2024|Forex News|0 Comments


Federal Reserve’s Rate Decision in Focus

The trading community’s attention is firmly on the Federal Reserve’s imminent interest rate decision. The general expectation is for rates to remain steady, but the real interest lies in the Fed’s dot plot. Traders are seeking insights into future rate cuts, with some predictions pointing towards a mid-year start. However, unexpectedly high inflation reports might restrict the extent of these cuts, injecting a degree of uncertainty into the oil markets.

Russian Supply Disruptions

Geopolitical tensions are critically influencing oil supply, especially from Russia. The conflict has led to a marked reduction in Russia’s refining capacity, resulting in increased crude exports. This shift is under close scrutiny, as prolonged disruptions could lead to a supply squeeze, particularly if Russian producers are compelled to reduce production due to export challenges.

US Inventory Data: A Key Indicator

Recent data from the American Petroleum Institute (API) shows a drop in U.S. crude and gasoline stockpiles, providing some support to oil prices. The market is now awaiting official data from the U.S. Energy Information Administration (EIA) for further direction. These figures are key in assessing U.S. oil supply levels and can significantly influence market sentiment.

Short-Term Outlook

Considering these factors, the short-term forecast for the oil market is cautiously bullish. The Federal Reserve’s decision could lead to market volatility, while supply concerns, particularly from Russia, offer a supportive backdrop. However, the strength of the U.S. dollar and evolving global economic conditions will be crucial in shaping this bullish trend.

Conduct your own research by contacting financial experts before making any investment decisions.

The cryptocurrency market is experiencing a significant correction that is not stopping. With over $500 million worth of positions liquidated, traders wonder if this signals the end of the recent bull market.  

A sharp sell-off prevails on the market, as indicated by the high number of liquidations. Within just a 24-hour window, liquidations have mounted, with Bitcoin (BTC) witnessing $107.14 million in liquidations and the total volume of liquidation exceeding $500 million.  

Bitcoin’s price performance

Bitcoin has clearly retreated from recent highs, currently sitting below the $60,000 mark. On the chart, BTC shows it has fallen below the short-term moving averages, which typically act as support levels. This could indicate that the bullish momentum has weakened.

BTCUSD
BTC/USDT Chart by TradingView

It reveals a sharp decline from a peak, with the price now approaching the 50-day moving average (around $56,276). If this level fails to hold, the next significant support is near the 100-day moving average (around $51,819). A breach below this level might lead to increased selling pressure, potentially indicating a more extended bearish phase.

This prolonged correction is unsettling for the market, as it indicates that investor sentiment may be shifting from overwhelmingly positive to cautious, if not outright pessimistic. It is a worrisome sign, particularly when the market was expected to stabilize after an initial correction at around $70,000.

The current severity of volatility has taken many by surprise. As the market navigates through this severe correction and faces a potential trend reversal, it is crucial for participants to stay cautious and, most importantly, as liquid as possible. Focusing on the longer-term outlook rather than short-term fluctuations might be the most viable strategy amid the unexpected market fluctuations we are witnessing now.

EUR/USD Forecast. Growth in the final wave of the diagonal triangle

By |2024-03-20T08:35:46+02:00March 20, 2024|Forex News|0 Comments


The market once again provides an opportunity for the euro to change the situation in its favor. After pushing the price beyond the channel and thus indicating that the rise is canceled, the price dropped slightly but quickly reversed and began to cautiously rise. Most likely, as previously assumed, this was manipulation, and wave iv took the form of a double zigzag, explaining the recent decline.

Therefore, the observed cautious rise is the beginning of the development of wave v. Thus, it may be worth trying to start buying at current market values, aiming to catch the movement in the final wave of the forming diagonal triangle.

Investment idea: Buy at 1.0870, Stop Loss at 1.0840, Take Profit at 1.1000.

EUR/USD. Growth in the final wave of the diagonal triangle.

Investing.com– Most Asian currencies moved little on Wednesday amid caution before more signals on interest rate cuts from the Federal Reserve due later in the day, with the dollar sitting at two-week highs. 

The Japanese yen extended its declines after the Bank of Japan struck a largely dovish chord, despite for the first time in 17 years. 

Dollar at 2-week high before Fed signals on rate cuts 

The and rose slightly in Asian trade, with focus largely on the conclusion of a Fed meeting later in the day.

The central bank is widely expected to . But any signals on potential rate cuts, specifically from a with Fed Chair Jerome Powell after the meeting, will be awaited.

Traders fear a potentially hawkish tilt from the central bank, given that inflation read hotter-than-expected for the past two months.

USDJPY at 4-mth high, EURJPY tests 2008 peaks 

Weakness in the yen saw the pair surge nearly 2% since Tuesday to around 151.30- its highest level since mid-November. Losses in the yen came even with Japanese markets closed for a holiday.

The yen fared even worse against the euro, with the pair surging to its highest level since 2008. 

Weakness in the yen came chiefly after BOJ Governor Kazuo Ueda said the central bank will maintain accommodative conditions to support the Japanese economy. His comments largely overshadowed the bank move away from negative interest rates and yield curve control.

Analysts at Citi said that U.S. interest rates remained the main drivers of the yen, and that the currency only stood to strengthen later in 2024, if U.S. rates began falling.

They also cautioned over potential intervention in currency markets by the Japanese government, especially if USDJPY crossed 152. 

Broader Asian currencies moved little, as anticipation of the Fed deterred any big bets. The Australian dollar rose 0.1%, with the pair recovering from sharp losses in the prior session after the Reserve Bank of Australia kept interest rates steady and struck a somewhat dovish chord.

The Chinese yuan was flat, with the pair trading just a whisker away from the psychologically important 7.2 level. The People’s Bank of China kept its benchmark unchanged as expected on Wednesday. 

The South Korean won’s pair rose 0.1%, while the Singapore dollar’s moved little. The pair rose above the 83 level.

Price Oracles in DeFi Explained

By |2024-03-20T07:11:13+02:00March 20, 2024|Forex News|0 Comments


HodlX Guest Post  Submit Your Post

 

In the world of DeFi (decentralized finance), oracles play a crucial role in ensuring the accuracy and reliability of data especially pricing data used within various protocols and platforms.

What are price oracles

A price oracle is a specific type of oracle that provides off-chain (external) price information to on-chain (blockchain) smart contracts.

Given the isolated nature of blockchains, smart contracts cannot access external information directly, and oracles serve as a bridge to bring this external data onto the blockchain.

Why price oracles are so important in DeFi

Price oracles are widely spread in DeFi. They are a core element of many crypto projects.

Lending protocols determine with oracles the correct collateralization levels and initiate liquidations when necessary. Algorithmic stablecoins maintain their peg to external assets.

Synthetic assets track prices of RWAs (real-world assets) to manage synthetic versions on the blockchain.

Any project that uses asset prices needs some kind of price oracle.

As oracles are widely used in crypto projects and almost always play a crucial part in them, oracle attacks have become one of the most popular types of attacks on crypto projects.

Types of prices oracles, their advantages, disadvantages and security issues

Chainlink price oracle

Arguably the most well-known oracle provider, the solution consists of a network of oracles (data feeds) that convey data into the blockchain.

Overview

A group of independent operators updates each data feed. Subsequently, a smart contract validates and aggregates data from these operators.

Operators are rewarded for their data-publishing activities.

Each data feed has its specific parameters, such as the minimum number of oracles, the minimum number of oracles required to update the price and the frequency of updates.

Data aggregation

Given that the data is supplied by various operators, a crucial step involves amalgamating them into a single value.

This process unfolds in two steps initially, operators utilize off-chain reporting, and then the data is supplied to the aggregator contract.

Off-chain reporting embodies a P2P (peer-to-peer) network of operators consisting of multiple nodes.

Every node signs and submits its price, and via a consensus mechanism, an aggregate transaction is crafted.

This transaction includes operators’ signatures and submitted prices and is subsequently validated on-chain.

Utilizing a network of operators with a consensus mechanism significantly reduces the cost of forming the final price  all aggregation calculations are performed off-chain, and only one final transaction is recorded while also maintaining the solution’s decentralization.

It’s worth noting that Chainlink price data feeds are not available in all networks and certainly not for all currencies.

The addition of additional currencies is possible, but they must meet specific Chainlink requirements, which can be expensive.

Therefore, when the necessary currency for a project is absent, other types of oracles must be considered.

Pyth price oracles

Another popular price oracle provider operates across more than 12 chains. Similar to Chainlink oracles, it comprises three main components, which are as follows.

  • Publishers who provide price data
  • Pyth’s oracle program, a module that aggregates data from publishers
  • Consumers, which are protocols that request price data

Let’s examine how the Pyth architecture works for the majority of the systems supported by Pyth.

For data aggregation, a protocol named Pythnet is used. It’s a Solana-powered application blockchain utilized by Pyth’s data providers.

These providers supply price quotes for each asset. Pythnet combines these prices to produce a single aggregated price.

Subsequently, the combined prices are transferred to target chains using the Wormhole protocol. Finally, the consumer contracts retrieve the prices from on-chain storage.

TWAP oracles

TWAP oracles compute the average price of a particular asset over a specific time interval.

As implied by the name, these on-chain oracles operate based on a principle that calculates the mean asset price over a predetermined time period.

While seeming straightforward in their functionality, deploying them securely presents notable challenges.

One of the pronounced advantages of utilizing TWAP oracles lies in addressing the issue of price manipulation within DEX pools.

In scenarios where a project is pegged to the instantaneous price of an asset, malefactors may exploit this by utilizing a flash loan to skew the asset’s price and subsequently execute an attack.

By leveraging TWAPs, the manipulator is compelled to maintain the distorted price over a particular duration, allowing arbitrage mechanisms to come into play and counteract the malicious intent.

Despite the apparent simplicity of TWAP oracles, ensuring their secure implementation can be a complex undertaking.

The resilience to attacks is contingent upon several factors, such as the effectiveness of the arbitrage mechanism, the pool’s capital volume, the protocol’s immunity to price manipulations, the network’s consensus mechanism and various other elements.

Generally, it can be posited that relying solely on TWAP oracles cannot be deemed entirely secure.

However, they can proficiently function as a complementary measure alongside other types of price oracles.

In synthesizing, while TWAP oracles serve to inhibit and complicate exploitative price manipulations in DEX pools by necessitating the maintenance of manipulated prices over a specified timeframe, their deployment should be approached with a meticulous understanding of their complexities and potential vulnerabilities.

Considering them as part of a wider, multi-faceted oracle strategy is instrumental in enhancing the robustness and security of blockchain projects in navigating the volatile and sometimes adversarial landscapes of cryptocurrency markets.

Open price feed

This is an oracle developed by the Compound protocol.

The main idea of the oracle is to combine prices from different sources originally Chainlink and Uniswap markets

The Open price feed oracle uses a special contract that allows a trusted source to update prices.

Once the price is updated, it’s compared to an anchor price from Uniswap pool.

If the price deviates from the anchor price more than initially set boundaries, the price update is discarded.

The anchor price is fetched with the TWAP mechanism described above.

Open price feed defends from incorrect data posted by an external price provider.

The downside is when the price fluctuates frequently, the TWAP price may be not updated and the actual asset price provided by an external source would be discarded.

Maker DAO oracles

Maker oracles are one of the oldest oracles in the EVM ecosystem.

Like Chainlink and Pyth, it uses an off-chain network where price broadcasters supply asset price evaluations.

The on-chain oracle module has two main contracts – median and OSM (oracle security module).

The ‘median’ component provides the Marker’s trusted reference price. It computes a median of received prices and stores its value.

The ‘OSM’ contract ensures that the stored price values are not taken before a certain delay has passed.

It should be noted that this price oracle is available only for whitelisted contracts.

Conclusion

Price oracles are a crucial part of the DeFi ecosystem. The security of numerous crypto projects depends on oracles.

Unfortunately, there is no best solution for a price oracle each oracle has its own limitations, advantages and disadvantages.

That’s why it’s important to know what oracles are available and to choose the best solution for a crypto project.

FAQ

In which crypto projects can price oracles be used?

Price oracles can be used in a multitude of crypto projects, especially those within the DeFi sector.

Examples of use cases include lending protocols which need to ensure correct collateralization levels, algorithmic stablecoins which require reliable price pegs to external assets and synthetic asset platforms which need to track RWA prices to manage their on-chain synthetic counterparts.

Is there a best solution for oracles currently available?

No, there is no one-size-fits-all best solution for oracles at the moment.

Each oracle has its own advantages and disadvantages, depending on specific use cases, security models and network compatibility.

Therefore, it’s pivotal to understand the available oracles and choose one that aligns best with a particular crypto project’s requirements and goals.

What are the dangers of using TWAP oracles?

While TWAP oracles offer certain merits, such as mitigating immediate price manipulations by averaging the asset price over a specified time, they are not impervious to threats and complexities.

Deploying TWAP oracles securely is notably challenging, and their resilience to attacks hinges on several variables including the arbitrage mechanism’s effectiveness, the liquidity pool’s capital and the network’s consensus mechanism, among others.

They might be used effectively in conjunction with other types of oracles to ensure enhanced security and functionality in a multi-oracle strategy.
