Bank for International Settlements: Swap spreads are reflecting investors' concerns about excessive bond supply. The Bank for International Settlements (BIS) pointed out that huge government loans are having an impact on the global interest rate market, saying that investors have demanded higher premiums for buying sovereign bonds. In its quarterly report released on Tuesday, the agency pointed out that the swap spreads of various currencies and maturities have narrowed rapidly in recent months, which are "signs of possible oversupply". As investors are worried about huge debt and deficit expansion, the yields of government bonds in the euro zone and Japan have recently exceeded comparable swap rates. This leads to the so-called swap spread becoming negative. Because national debt is usually regarded as a safer investment than interest rate swap, it is unusual for the swap spread to enter the negative range. According to the Bank for International Settlements, the negative swap spread seems to reflect the pressure faced by investors and intermediaries because they need to absorb more government bonds in the near future. In the United States, the swap spreads for some maturities have been negative for many years.The Economic Affairs Committee of the Brazilian Senate approved Nilton David as the director of the central bank's monetary policy.At least six Syrian naval vessels were attacked by Israeli troops on Monday.
