■ LISA pathfinder would help LIGO’s (a ground based gravitational waves observatory) work.
■ Seismic, thermal and other noise sources limit LIGO to higher-frequency gravitational waves.
■ But finding signals from more exotic events, such as mergers of supermassive black holes in colliding galaxies, requires the ability to see subtle frequencies, a sensitivity level only possible from space.
■ So, LISA Pathfinder was intended as a stepping stone to the level of performance needed for a full-scale gravitational wave observatory.
• Statements 2 is incorrect: The size of this auction is $5 billion and the tenor for swap is three years. Dollar-Rupee (USD/INR) swap auction • The RBI has different tools through which it injects liquidity into financial markets. Adjusting repo rates and purchasing bonds by conducting open market operations (OMO) is a couple of tools which the RBI uses regularly either to increase or decrease the currency supply in the market. • The recently announced ‘swap auction’ is one such tool. This is being done to increase the supply of rupees in the market. Technically, this activity is being termed as a USD/INR Buy/Sell Swap Auction. • Through this auction, the RBI will buy US dollars from banks totaling to $5 billion. In turn the RBI will pay rupees to the participating banks at the current spot rate. At an average spot rate of 70 per dollar, the RBI will able to infuse about Rs 35,000 crore into the system through this auction process. • Simultaneously, the banks will agree to buy-back the same amount of dollars from the RBI after three years — the tenor of this auction. • The participating banks have to bid in the auction by quoting a forward premium in terms of paisa that they will pay to buy back the dollars. • For example, if the spot exchange rate is 70 to a dollar, say Bank A quotes a premium of 150 paisa and bids for $25 million. • So, the bank will get Rs 175 crore ($25 million multiplied by the exchange rate of 70). • After three years, the bank has to pay back approximately Rs179 crore ($25 million multiplied by the exchange rate of 71.5) to the RBI to buy back $25 million. Why is it important? • Indian financial markets have been undergoing liquidity problems since the IL&FS crisis emerged last year. The market is likely to see even tighter liquidity from a rush to pay advance tax as the financial year-end is less than a week away. • For the RBI, the auction will help boost its forex reserves by another $5 billion.
