Following is a list of company earnings scheduled for release March April 2, along with an earnings preview for select companies. Items that protect you from the virus are medical expenses, the tax agency says.
But on Monday, when Abu Dhabi begins selling futures contracts for its oil and then shipping the barrels from Fujairah, it will mark an aggressive shift by the emirate. Investors globally are clamoring for commodities because of their high yields relative to other assets and to protect themselves against any rise in inflation. Creating a new benchmark will hardly be easy. Oil traders dislike change, especially when they believe markets already do a good job matching supply and demand. It was forced to shelve the plan indefinitely.
Murban will also face competition regionally. Platts publishes price assessments for Dubai oil and the Dubai Mercantile Exchange trades futures for Omani crude. Both act as benchmarks for Middle Eastern shipments to Asia. Abu Dhabi says the combination of high supply, easy access to oil-consuming markets from Fujairah and the absence of trading restrictions will attract plenty of buyers to its exchange.
The futures platform will be run by Atlanta-based Intercontinental Exchange Inc. The Murban exchange and the capacity boost could raise tension within the Organization of Petroleum Exporting Countries, according to Hari of Vanda Insights. The Gulf states dominate the cartel and tend to prize unity.
They also began unprecedented production cuts last year to bolster prices as the coronavirus pandemic spread.
West Texas Intermediate lost as much as 2. Crude has been hit by rising volatility in recent sessions, with WTI swinging between gains and losses last week. Traders were also tracking the advent on Monday of a significant new contract, with Abu Dhabi kicking off futures for its oil in a bid to establish a new regional benchmark. Oil is still set to close out a fourth consecutive quarterly gain this week, aided by sustained supply curbs imposed by the Organization of Petroleum Exporting Countries and its allies, and optimism that global demand will expand as coronavirus vaccines get rolled out.
Rates for tankers had increased, boosting the cost of shipping crude around the world. Despite progress with vaccines, the Covid pandemic remains a challenge. Global cases rose for a fifth week, with several European nations facing a resurgence.

Also in Asia, the Philippine capital is also back under strict curbs. This time around, Goldman Sachs Group Inc. Citigroup Inc. Bloomberg -- As the global economy picks up speed, investors are dusting off the Canada playbook. Covid vaccinations are gaining momentum and fiscal support is helping the growth outlook, lifting bond yields.
Global investors have overlooked Canada for years in favor of countries with greater choice in high-growth technology stocks, primarily the U. Canadian equity exposure is also increasing, according to Bank of Nova Scotia analysts. They say the valuation gap with U. Financials are nearly one-third of the benchmark; rising rates and an improving economy help insurers such as Manulife Financial Corp.
The first decade of this century was better for emerging markets such as Brazil and commodities-driven developed countries including Canada. Bloomberg -- Nomura Holdings Inc. The Tokyo-based firm also canceled plans to sell dollar-denominated bonds. While the Nikkei newspaper reported that the losses arose at its U. Nomura said the estimate of the claim against the client may change depending on unwinding of the transactions and market price fluctuations. It will continue to take steps to address the issue and make a further disclosure once the impact of the potential loss has been determined.
Bitcoin’s mining difficulty just had its biggest increase since early

Or, if the price of Bitcoin starts rising, you may see an influx of miners turning on and bumping the hashrate. Similarly, a halving is going to affect who's mining and the hashrate in the system, which is what we saw this past May. In May, the reward went from Now, you'll only receive half the reward for the work you put in, or you'll need to do double the work to receive the same reward as in the past.
After a halving, miners may decide that mining Bitcoin is going to take too much of an investment for any return, and may leave the system, dropping the hashrate. That's what we saw happen in May after the halving: Difficulty went down because of the drop in hashrate.
So then why did the difficulty rise again, and just hit a record high? The halving didn't affect Bitcoin prices, which have still been skyrocketing, so many of those miners who left may be back — along with upgraded equipment that will hash faster. Because of the lower difficulty after the halving, new miners may have jumped into the network, bumping the hashrate as well.

But rising difficulty is going to mean that miners need to seriously consider the state of their equipment. Older hardware isn't going to be profitable anymore, so miners will have to invest in upgrades to keep their mining efforts sustainable. Higher difficulty may force individual miners to turn off for good — or may prompt them to start looking at outsourcing their mining to farms who can easily handle the hashpower. So, to return to the original question: Have the swings in difficulty in the past few months in Bitcoin mining been good for the system, or bad for the system…?
To remedy this, the protocol increases the difficulty of the puzzle when hashing power is increased. Ethereum uses this style of consensus algorithm , but it also includes a difficulty bomb, which increases the overall difficulty at specified block heights. In turn, such an increase decreases the profitability of mining — this is the intended effect.

As time goes on, it becomes exponentially harder to generate blocks, and rational miners will abandon the practice. The network is expected to transition to staking in the future — the difficulty bomb seeks to dissuade anyone from continuing to generate blocks on the old chain.
Amongst other things, this could prevent the chain from being split into two contentious forks. It has a secondary effect of preventing the stagnation of development on the Ethereum chain, as developers must frequently upgrade it to prevent it from becoming unusable.
