Liquidity and Transparency in Bank Risk Management. By Lev Ratnovski
IMF Working Paper No. 13/16
http://www.imf.org/external/pubs/cat/longres.aspx?sk=40258.0

Summary: Banks may be unable to refinance short-term liabilities in case of solvency concerns. To manage this risk, banks can accumulate a buffer of liquid assets, or strengthen transparency to communicate solvency. While a liquidity buffer provides complete insurance against small shocks, transparency covers also large shocks but imperfectly. Due to leverage, an unregulated bank may choose insufficient liquidity buffers and transparency. The regulatory response is constained: while liquidity buffers can be imposed, transparency is not verifiable. Moreover, liquidity requirements can compromise banks' transparency choices, and increase refinancing risk. To be effective, liquidity requirements should be complemented by measures that increase bank incentives to adopt transparency.

Conclusion

The paper emphasized that both liquidity buffers and — in a novel perspective — bank transparency (better communication that enhances access to external refinancing) are important in bank liquidity risk management. In a liquidity event, a liquidity buffer can cover small withdrawals with certainty. Transparency allows the bank to refinance large withdrawals too, but it is not always effective. Banks may choose insufficient liquidity and transparency; the optimal policy response is constrained by the fact that bank transparency is not verifiable.

The paper offers important policy implications, particularly for the ongoing liquidity regulation debate. The results caution that the focus on liquidity requirements needs to be complemented by measures to improve bank transparency and access to market refinancing. Without such measures, liquidity requirements may not achieve the full potential of improvements in social welfare, and under some conditions may have unintended effects. We also highlight the need for better corporate governance as a way to improve bank transparency, and the scope to use net stable funding ratios to increase the effectiveness of liquidity requirements.

Q&A session with a Japanese citizen on contemporary politics

The comments of a Japanese citizens on politics and our questions:

[...]

- what do supporters of Tokyo's governor say about him? I always read comments against him, but he wins the elections, so there are lots of (silent) supporters.

our present PM Shinzo Abe is supported by citizens pretty well so far. he showed a policy for economics called "Abenomics" lately. then even though nothing's done yet just show it to us, stock prises' been rising and rising, curency rate's been much better (Yen got too much strong and international exporting companies as even Sony, Panasonic or Toyota were getting big loss for these 3 years).

also, his strategy of international is evaluated. former government always compromised to Chinese or Korean's unreasonable accusations just for economical reasons. but he is trying to build a strong relationships between South-east Asian countries, Australia, India and Russia. especially SE Asian countries welcome this because they've been threatened by Chinese forces, they've actually wanted Japan to have leadership against China.

he seems doing very fine now.

i have to say many of japanese medias have big problems... many people in medias are kind of "traitor". they pick up "noisy minority" and show it just like the majority to give Japan bad names to the world... it's fine if their opinions are to make things better, but just critisise. it will be too long if i explain this.

Question: what do supporters of nuclear arms say? I always read assurances about the Japanese not wanting the A-bomb, but from time to time some politician says that Japan is considering protecting herself (against North Korea and China)

i think there are not many supporters of nuclear arms. some polititians and scholars are saying to discuss it. because almost all of Japanese has a sort of allergy for nuclear weapons (it comes from trauma of WW2) and even discussions are taboo. indeed, even though we have been aimed by Chinese and maybe Korean A-missiles. so they are claiming to get out of trauma now. also they say even only discussion will be a detterent to the countries. (personally i agree with them, we don't need to have it, but it's nonsense not to even talk). recently it seems peoples who agree with it has been increasing.

PM Abe is trying to have a good relationship between US, but on the other hand, trying to protect ourself with proper forces. and it's generally supported by majority (at least it seems so to me). almost all of people likes US better than China in politics, but lately people started to think stand by ourselvs.

actually now is the turning point of Japan after WW2 i think...

if you want to understand how Japanese are, it might be important to understand "Shinto". it's a domestic thoughts/philosophy of Japan, quite religious but not religion. it says we have 8 million gods in our land - god of fire, god of wood, god of sea, god of marrige, god of traffic, god of study... so we should thank to everything, be good and respect others. it is the base of moral of Japanese, we are brought up with it by our parents. it's easy to accept other religion for Shinto, because any god or buddha of other religions can be one of the god. (Japanese buddism are a lot influenced and mixed with Shinto). our Tenno (emperor) is regarded as offspring of the god. http://en.wikipedia.org/wiki/Shinto

last year, South Korean president insulted Tenno, then all of Japanese citizens got angry, (i have never seen such angry Japanese ever!), i understood Tenno is the symbol of this country and Shinto at the moment.

sorry it's getting out of focus.

[...]

take care,
