LONDON (Reuters) - Central banks could help reduce volatility in short-term funding markets used by banks and big business by lending out more securities used as collateral, a group of policymakers from around the world said on Wednesday.
A committee of the Bank for International Settlements also said in a study on how repurchase agreements, or repos, function, that debt management agencies could sell more securities that were becoming scarce.
The $9 trillion global repo market, which allows borrowers to pawn securities for short-term loans, is seen as essential for the functioning of global financial markets.
However, the entire sector is struggling to adjust to the after effects of a series of financial crises and the regulatory environment that has followed them, the committee said.
Some high-quality euro zone government bonds -- typically used as collateral in repo markets -- have deeply negative yields mainly because of scarce supply created by the European Central Bank's asset-purchase program.
The ECB has a scheme to lend bonds it has purchases but that has done little to prevent short-dated German government bond yields hitting record lows in recent months. DE2YT=TWEB
"Where such facilities already exist, central banks might consider ways to increase their efficacy by reducing barriers to access," the committee said in the study, released on Wednesday.
