Rupee falls to 63 per dollar

The rupee fell to a record low on Monday and looked poised for further losses, with a series of measures unveiled last week failing to stall its decline.
The currency fell as far as 63.22 to the dollar, breaching the previous low of 62.03 hit on Friday.
Some dealers are expecting further dollar selling by the central bank as well as other measures to prop up a currency that is down 10.8% in 2013, making it the worst performer in emerging Asia.

  • Who was behind Friday's market crash

Traders seemed unconvinced about the efficacy of steps unveiled last week to contain the current account deficit at 3.7% of gross domestic product (GDP) during the current fiscal year, sharply lower than the record high 4.8% in the previous year.
"Forex intervention will continue by the central bank. Further measures are expected from the RBI but are unlikely to be effective. The rupee is expected to touch 63 in no time," said Param Sarma, chief executive at Brokerage NSP Forex.
The partially convertible rupee closed trading at 61.65/66 last week.
The rupee's tumble has fuelled expectations of more action from the Reserve Bank of India (RBI), which last week curbed outflows from companies and individuals, roiling stock and bond markets on Friday.
Policymakers later stepped in to assuage nerves that the government was not looking at curbing foreign money outflows.
"Our primary concern is that the policy authorities still don't 'get it' - thinking this is a fairly minor squall which will simmer down relatively quickly with fairly minor actions," Robert Prior-Wandesforde, an economist at Credit Suisse, wrote in a note on Monday.
"If this remains the case, then a swift move to 65 against the US dollar is probable, which in turn should help focus minds."
The rupee has been the worst performer in Asia since late May, when the US Federal Reserve first signaled that it may begin tapering its monetary stimulus this year, sparking an exodus of cheap money from emerging markets worldwide.
"The panic is overdone. Foreign exchange reserves are more than adequate. We also think inflows would gradually start to come in while the RBI will also continue to intervene in the market," said Samir Lodha, managing director at QuantArt Market Solutions, a consultancy and brokerage in Mumbai.
Net outflows from the bond and equity markets have totalled $11.4 billion since late May.
The bond market has borne the brunt of the outflows, with foreigners taking out around $10 billion since May 22.
Equity markets have remained relatively insulated with outflows from the cash market at less than $100 million on Friday, when the main stock benchmarks fell about 4%, the most in nearly two years. Heightened selling in equities could exacerbate the rupee's falls, dealers feared.
Mumbai's main stock index fell 1.2% on Monday.
Traders in Hong Kong reported continued selling in Indian bank cash bonds as fast money increased short positions and increased protection buying widened credit default swap spreads.
Analysts also are concerned about growing bad loans in the June-quarter earnings of lenders like State Bank of India as slowing economic growth spurs defaults by companies and individuals.
State Bank of India at mid-315 basis points (bpd) has soared from end-May lows of 180 bps. Government bond yields remained at 21-month highs with the 10-year bond at 8.95%, up 7 bps.

Here's how sailors can be saved in INS Sindhurakshak type disasters

 The Indian Navy's Sindhurakshak submarine is seen in Visakhapatnam in this February 13, 2006 file photo.



A major fire broke on INS Sindhurakshak on August 14, sinking the vessel at its dock in Mumbai.
What happened to 18 sailors that were onboard is not yet known, apart from 4 whose dead bodies were recovered recently.
If a tragedy like this would have happened with a U.S. Navy vessel, could the personnel onboard be saved.
The answer is yes and there are two ways to go about it: one is that a tethered chamber is lowered to the crippled submarine and then raised with the sailors, another is by using a deep submergence rescue vehicle (DSRV), Discovery News reported.
The U.S. Navy is known to use tethered method, which has three components - one each for every stage of a rescue operation.
In the first stage of Submarine Rescue Diving Recompression System (SRDRS), a diver wearing a specialized suit, called an atmospheric dive system, which is capable of reaching depths of 2,000 feet, swims to the sub to make sure that the hatch is accessible and if there are any survivors.
Once it is clear that people have survived and are trapped inside and the hatch is in working condition, the next step taken is to call in a remotely operated vehicle, called a pressurized rescue module (PRM) - typically crewed by two people, the vehicle - which is also capable of diving to 2,000 feet, is able to hold an additional 16 people. It links to the submarine hatch using a ‘skirt,’ which is essentially a tube covering the hatch and pushes out the water with pressurized air.
The outside water pressure is able to seal the tube onto the hatch the same way air pressure holds a suction cup to a wall.
The sailors then make an exit from the submarine through the skirt, they then board the PRM and go up to the surface where it docks with a larger pressure chamber.
The chamber then lowers the air pressure inside until it matches that outside in order to avoid giving the rescued sailors decompression sickness.

Kepler Supernova, Famous 1604 Star Explosion, May Have Been Triggered By White Dwarf


 Kepler Supernova

Scientists have conducted a postmortem exam on the last gigantic star explosion ever observed by the naked eye in our galaxy, revealing that the supernova was triggered by a compact white dwarf containing more heavy elements than the sun.
The supernova suddenly appeared in the night sky in 1604. Brighter than all other stars and planets at its peak, it was observed by German astronomer Johannes Kepler, who thought he was looking at a new star. Centuries later, scientists determined that what Kepler saw was actually an exploding star, and they named it Kepler's supernova.
The recent cosmic autopsy — made possible by X-ray observations from the Japan-led Suzaku satellite — could help scientists better understand phenomena known as Type Ia supernovae. [Supernova Photos: Great Images of Star Explosions]
"Kepler's supernova is one of the most recent Type Ia explosions known in our galaxy, so it represents an essential link to improving our knowledge of these events," Carles Badenes, an assistant professor of physics and astronomy at the University of Pittsburgh, said in a statement from NASA.
Type Ia supernovae are thought to originate from binary systems where one at least one star is a white dwarf — a tiny, superdense core of a star that has ceased undergoing nuclear fusion reactions.
Gas transferred from a "normal" star in the pair may accumulate on the white dwarf, or if both stars in the system are white dwarfs, their orbits around each other may shrink until they fuse together. In either case, when the white dwarf or white dwarf conglomerate puts on too much weight (around 1.4 times the sun's mass), a runaway nuclear reaction begins inside, eventually leading to a brilliant supernova.
To get a better picture of the star's makeup before it blew up, Badenes and colleagues probed the chemical signatures in the shell of hot, rapidly expanding gas left by Kepler's supernova using 2009 and 2011 observations from the Suzaku satellite's X-ray Imaging Spectrometer.
The X-ray spectrum revealed faint emissions from highly ionized chromium, manganese and nickel, as well as a bright emission line from iron. The ratios of these trace elements in the supernova remnant show that that the original white dwarf likely had about three times the amount of metals found in the sun, the researchers said.
Kepler's supernova remnant is thought to be 23,000 light-years away. Compared with our solar system, it is much closer to the Milky Way's crowded central region, where star formation was probably more rapid and efficient, leaving interstellar gas enriched with greater proportions of metals. This would explain why Kepler's supernova seems to have formed out of material that already had a higher fraction of metals.

The study didn't solve which type of binary system triggered the supernova, but the researchers say the white dwarf was relatively young when it exploded — no more than a billion years old, or less than a quarter of the sun's current age.
"Theories indicate that the star's age and metal content affect the peak luminosity of Type Ia supernovae," Sangwook Park, an assistant professor of physics at the University of Texas at Arlington, explained in a statement. "Younger stars likely produce brighter explosions than older ones, which is why understanding the spread of ages among Type Ia supernovae is so important."
By better understanding Type Ia supernovae, Park added, "we can fine-tune our knowledge of the universe beyond our galaxy and improve cosmological models that depend on those measurements."
Astrophysicists from the United States and Australia won the Nobel Prize in physics in 2011 for their discovery that the universe's expansion is accelerating — a revelation based on measurements of Type Ia supernovae that led to the concept of dark energy.
