comment Is inverted Japanese style curve persistent when negative rates are real / market - observed?
Thank you a lot for the article-link @haginile. I'll edit the question, as you pointed on the June14 JPY curve. My question is about the JPY curve/inverted style, in general: will real market negative rates become more negative in1 year, and then inflect to positive values, or will they grow in magnitude and "stay" negative?

comment Implied Probability of Default from Bond Prices
I understand survival as a function of delta t (you are non dead between the moments t0 and T) while I understand non-default as a function of t (you are not dead at moment T). Survival is the investment point of view and non-default is the liquidation approach.

comment How popular is the IRR as a tool for capital budgeting, nowadays?
what I meant is that you make the comparison of "standard" IRR with the funding rate in order to decide if investment is profitable or not, assuming that all CFs are discounted at it. But this does not correctly take into account the RF/devaluation of the different future cashflows, as the FUTURE interest free risk rate is unknown, while you assume that you keep getting funded at the CURRENT funding rate, in a dynamic analysis (you estimate future parameters). By saying that the future funding rate is going to be the RF and future investment R=RF, you are almost sure to make a true assumption.

comment What is the difference between Option Adjusted Spread (OAS) and Z-spread?
Mathematically, there is an interesting paper related to the non-linearity of this relationship (practically credit spread/o), in "Next Generation Models for Convertible Bonds with Credit Risk", p70, at wilmott.com/pdfs/030813_ayache.pdf

comment Why for one year (and not two or three) government bonds (there is a spike for Switzerland & Denmark)?
Less demand for the 1year in Denmark because of the eurozone resque fund to come (anticipated/known few months in advance). Is Switzerland expected/going to issue 1Y positive bonds as well? Nov 27: The eurozone rescue fund opened books this morning via JP Morgan, Morgan Stanley and Natixis at guidance of 0.23% to 0.25% with pricing scheduled for later on Tuesday. The transaction will be rated A-1+/P-1/F1+, which are EFSF's short-term debt ratings.

comment Government bonds with negative yield
Cash is limited and the monetary mass is not sufficient. Also cash is on its dissapearance road. Here there is the governmental view of the French government, to replace cash with software money, for example economie.gouv.fr/files/rapport-moyens-paiement-2012.pdf. A sort of English-ed version: knowledge.wharton.upenn.edu/article.cfm?articleid=3017

Yes. But you are still exposed to the credit risk of the company issuing the bond.

comment Should portfolio be optimized by marking to the future than marking to market (excluding currencies)?
I mean marking to the t_f - "future"'s market, not to t_0 -today's market: it is the value at t_f that counts. It is a sort of liquidity premium/spread for a given liquidity horizon: Say you have i_0=10^9 CHF invested/given at t_0 and you want/need to be sure that you have l_f=9*10^9 CHF liquid/received at t_f. Than you optimize/calibrate your model to show that you have l_f at t_f, and not to have i_0 at t_0.(Because the utility of the l_f is larger than the utility of i_o where involving in the utility your line of business: FX, if you want to pay retirement, fixed equity if in housing...)

comment Observed market price for the August-Greece-paid bonds where the NPV of the bond or of an option?
by the defintion of the NPV, one is supposed to have a model which has the NPV of the bond equal to the market value. The way to do the calibration is via the (credit) spread, which is supposed to express in a continuous way the rating state/probability of default. But (from the accounting point of view) one does not discount the incoming cash flows based on the credit state of the borrower, because it has already entered in the interest rate that you are charging for giving the principal away :(

Thank you, @BlueTrin. NPV is supposed to be the difference between an investment's market value and its cost. The market value has been very low. There are 3 options: 1. the cost of the investment is negative, 2. the NPV did not match the market value (it should be even lower than the market value), 3. this definition of NPV is no longer exact. What you are talking about is the expected (credit) gain, which favours option 3?
