Today I began an investigation to analyze this claim.</p><p>Here&#8217;s my bias: at the first investment shop I worked in, the high yield manager told me that there is a nominal yield for high yield bonds which reflects the risk.  It doesn&#8217;t matter where Treasury yields are, high yield bonds don&#8217;t care.  As a result, when people in the media, or writing blogs those argue that high yield is cheap because yield spreads are wide, it is time to disregard then when Treasury yields are artificially low, because of government interference.  (Financial Repression)</p><p>High yield bonds do care about credit conditions.  High yield bonds do care about the stock market.  From all of my research, high yield bonds are highly sensitive to credit conditions, particularly those of its industry.  They are also sensitive to the stock market.  After all, if the high yield bonds are doing badly, the stock is doing worse.</p><p>And here&#8217;s the rub: high yield bonds do not react to yields on Treasuries, except negatively, because when Treasuries rally hard, times are not good, and high yield bonds do poorly, with yields rising.</p><p><a

src='http://alephblog.com/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </em></p></blockquote><p>My personal approach to asset allocation is similar to Warren Buffett, or Value Line.  I invest mostly in stocks, and keep a bunch of safe assets for liquidity.  As the market rises, I add to my safe assets.  As the market falls, I buy stocks.  In October of 2002, things were so bad that I depleted my safe assets, an everything was in stocks.</p><p>In general, I think most complex asset allocation strategies are overly complex.  In general, there are safe and risky assets.  Asset allocation should first focus on the division between the two.  Typically the safe assets are high quality bonds and cash equivalents.  Sometimes there are more opportunities, sometimes fewer.  Safe asset levels should reflect that.</p><p>The second focus of asset allocation should be liquidity needs.  Even if there are a lot of promising opportunities to deploy cash, if the liability that funds the assets needs cash, have cash ready for it.  If you invest in limited partnerships or private companies where the assets are locked up for a period of time, have a sense of what your maximum level of illiquidity is (what will you with certainty never need to tap?), and ladder the investments so that like a laddered bond portfolio, you always have some illiquid investments maturing each year, providing fresh cash for deployment where current opportunities are most promising.  These top two ideas are very basic, but <a
href="http://alephblog.com/2009/09/17/alternative-investments-illiquidity-and-endowment-management/" target="_blank">even experts neglect them at times</a>.</p><p>The third focus of asset allocation is choice of risk assets, which is how I view your question.  There my view of asset allocation is like that of GMO.  Forecast future returns off of free cash flow yields; invest accordingly.</p><p>Don&#8217;t pay much attention to volatility, but aim for what is most likely, and bend a little in the direction of what can go wrong.  Most of the time, over longer periods of time, what is most likely happens on average; that&#8217;s why it is most likely.</p><p>Maybe &#8220;Too many cooks spoil the broth.&#8221;  I have enough trouble trying to work with momentum versus mean reversion.  I would lean toward having one AA strategy that fits with my broader asset management practices.  But on the other hand&#8230;</p><p>Suppose we did have five asset allocation models, and what their results were encouraging various investors to do.  If we thought that one of the models had been too hot of late, and was attracting too much money, and distorting ordinary market relationships, maybe that could give us a signal to make sure our asset allocation de-emphasized the results of that method.  Timing of course would be difficult, it always is, but seeing the results of the five methods could provide a fuller view of choices faced by our competitors.</p><p>I&#8217;m not sure that using the average of a number of asset allocation models will provide the best result, but I think that understanding what other players in the market are doing could lead to better decisions.</p><p>I&#8217;m open to your thoughts, and the thoughts of other readers here.  Anyone have a better idea?</p> ]]></content:encoded> <wfw:commentRss>http://alephblog.com/2012/02/10/4550/feed/</wfw:commentRss> <slash:comments>9</slash:comments> </item> <item><title>Against Risk Parity, Redux</title><link>http://alephblog.com/2012/02/07/against-risk-parity-redux/</link> <comments>http://alephblog.com/2012/02/07/against-risk-parity-redux/#comments</comments> <pubDate>Tue, 07 Feb 2012 14:54:13 +0000</pubDate> <dc:creator>David Merkel</dc:creator> <category><![CDATA[Asset Allocation]]></category> <category><![CDATA[Banks]]></category> <category><![CDATA[Bonds]]></category> <category><![CDATA[Macroeconomics]]></category> <category><![CDATA[Portfolio Management]]></category> <category><![CDATA[Quantitative Methods]]></category> <category><![CDATA[Real Estate and Mortgages]]></category> <category><![CDATA[Stocks]]></category> <category><![CDATA[Structured Products and Derivatives]]></category> <category><![CDATA[Value Investing]]></category> <guid

href="http://alephblog.com/2010/08/06/the-education-of-a-corporate-bond-manager-part-x/" target="_blank">The Education of a Corporate Bond Manager, Part X</a>.&#8221; There is no generic risk in the markets.  There are many risks.  Interest rate risk and credit risk are different topics.   There are bonds that have interest rate risk but not credit risk &#8212; long Treasuries.  There are bonds that have credit risk but not interest rate risk &#8212; corporate floating rate notes, my favorite example being floating rate bank trust preferred securities.</p><p>It is not raw price volatility that drives investment results as much as the underlying drivers of the volatility.  For fixed income, I described those in the two articles linked in the last paragraph.  During non-credit-stressed times, a bank&#8217;s 30-year floating rate trust preferred security is roughly as volatile as a five-year noncallable bond that it issues.  But during times of credit stress, the first security becomes volatile, whereas the second one doesn&#8217;t.  The first moves in line with 30-year swap yields, LIBOR, and long junior bank spreads.  The second moves in line with 5-year Treasury yields, and short senior bank spreads.  The underlying drivers have little in common, and when things are calm, their volatilities are similar, because the drivers aren&#8217;t moving.  But when the drivers move, which in this case is one correlated driver, credit stress (30-year swap &amp; junior bank spreads go a lot higher), the volatilities are very different, the first one being high and the second one low.</p><p>Thus equating volatilities across a bunch of asset subclasses, investing less in the volatile, and levering up the non-volatile, is hard to do.  History embeds all the curiosities of the study period, and calls them normal, and that past is prologue.</p><p>From the <a
href="http://www.forbes.com/forbes/2012/0213/investing-jeffrey-gundlach-rise-interest-rates-recession-pick-poison.html" target="_blank">Pick Your Poison</a> article above, what I think is the (lose) money quote:</p><blockquote><p><em>Gundlach insists most money managers misunderstand junk bonds, comparing them to 5-year Treasurys to determine how rich their yields are, when the correct comparison should be to 30-year Treasurys.</em></p><p><em>How can Gundlach compare junk bonds, which do better when the economy heats up, with long-term Treasurys, which get killed when the economy revs up and the Fed raises interest rates?</em></p><p><em>That’s irrelevant, he responds. The thing to look at is volatility, because that tells you the odds you will have to sell at a loss when you need to raise cash in an emergency. On that basis, junk bonds that were trading at a seemingly reasonable spread of 5 percentage points, or 500 basis points, to 5-year Treasurys in mid-2011 were actually trading at an intolerably low 250-basis-point spread to the proper bond. (By then DoubleLine had cut its junk bond allocation from 10% to 1%.) Sure enough, junk fell 12% as the year went on, and the spread to 30-year Treasurys has doubled since mid-2011.</em></p><p><em>“It’s called risk parity,” Gundlach says. “There’s only two investors who seem to understand it—me and Ray Dalio,” the highly successful manager of $122 billion (assets) Bridgewater Associates.</em></p></blockquote><p>Personally, I don&#8217;t think Gundlach makes his money that way for his funds, but in case he does, how should a good bond manager view junk bonds?</p><p>First, ignore Treasuries &#8212; they aren&#8217;t relevant to the price performance of junk bonds.  I&#8217;ve run the regression of Treasuries vs junk bond index yields many times.  It&#8217;s barely significant for BBs, and insignificant thereafter.  Second, look at stock market indexes of industries that lever up and issue junk debt.  Junk corporate debt is a milder version of junk stocks, i.e., the stocks that issue junk debt.</p><p>Third, a corollary of my first reason, realize that risks with junk aren&#8217;t driven by spreads, but yields.  With highly levered, or very junior debt, it does not trade on a spread basis, but on a price basis.  Anyone looking at spreads will see too much volatility versus yields and prices.</p><p>But mere volatility won&#8217;t tell you the riskiness.  Indeed, when economic times are good, junk will do well, and long Treasuries do poorly.  Now, maybe that makes for a very noisy hedge, but I wouldn&#8217;t rely on it.</p><p>And, volatility is a symmetric measure, which as bond yields get closer to zero, the symmetry disappears.  Most asset classes display negative skew and fat tails, which also makes volatility problematic as a risk measure.</p><p>Going back to <a
href="http://alephblog.com/2012/02/04/against-risk-parity/" target="_blank">my first piece on the topic</a>, if I were applying risk parity to a bond portfolio, it would mean that I would have to buy considerably more of shorter and higher quality instruments, and lever them up to my target volatility level, somehow with spreads large enough that they overcome my financing costs.  Now, maybe I could do that with mispriced mortgage securities, but with the problem that those aren&#8217;t the most liquid beasties, particularly not in a crisis if real estate is weak.</p><p>I guess my main misgiving is that levered portfolios are path-dependent, as pointed out in the GMO piece above.  You can&#8217;t be certain that you will be able to ride through the storm.  The ability to finance short-term disappears at the time it is most needed.</p><p>Now, if you can get leverage after the bust, and invest in beaten-up asset classes, you can be a hero.  But that&#8217;s a time when only the most solvent can get leverage, so plan ahead, if that&#8217;s the strategy.  If an investor could consistently time the liquidity/credit cycle, he could make a lot of money.</p><p>As the GMO piece concludes, the only benchmark that everyone could hold would be a proportionate slice of all of the assets in the world, which implicitly, would strip out all of the leverage, because one would own both the shares of the company, and the debt it owes, and in the right proportion.</p><p>So I don&#8217;t see risk parity as a silver bullet for asset allocation.  I think it will become more problematic, as all strategies do, as more people show up and use it, <a

Under theoretical conditions, one could make extra money doing this, and with less risk than just a common stock portfolio.</p><p>That makes sense when few are doing it, but not when many are doing it.  When I worked for Hovde Capital Advisors, I highlighted to the group how hedge funds were forcing every asset class to the same level of riskiness.  A <em>Grants Interest Rate Observer</em> article on Leveraged Non-prime Commercial Paper is etched on my mind as emblematic of that era.</p><p>Risk parity can work so long as the total riskiness of the system does not get too high, as it did in 2007-8.  But if it does get too high, the assets that are levered face disadvantages versus volatile unlevered assets.  Failures of leverage feed on themselves, and lead to a real washout.  Failures of growth stocks don&#8217;t do that to the economy.</p><p>Risk parity turns managers into bankers, or worse yet, asset managers that specialize in non-AAA investment grade portions of structured securities deals.  Most asset managers are not used to thinking like bankers, largely because they think in terms of total return, and because they don&#8217;t have a balance sheet.  Their capital can run at will, unlike banks that have deposit stickiness, savings accounts, CDs, ability to borrow from the FHLBs, etc.  The banks can hold the assets to maturity, they have a buffer against losses in their capital, and don&#8217;t have to mark to market in an assiduous manner (though they *should* have to do so).</p><p>Think of the mortgage REITs in the most recent crisis &#8212; the ones that did the best were the least levered and had the longest terms for their repo lines.  In the short run, that costs more than the vain idea that one can roll over their repo lines every night, and that repo haircuts won&#8217;t rise.  Crises lead to a failure of both ideas, together with a set of forced sellers driving down the price of assets being repo-ed, which sometimes leads to a cascade where repo terms get progressively tighter, and only those that were the most conservative at the start of the crisis survive.</p><p>There is a Wall Street aphorism, &#8220;The fool does at the end of a bull market what the wise man does at its beginning.&#8221;  Risk parity falls into that bucket.  Early adopters of new asset classes and liability structures typically do well, but when they become mainstream, the dynamics can be ugly, as we learned in 2007-present.</p><p>So ignore the idea of risk parity.  Risk managers are not bankers, they don&#8217;t have the capacity to play leveraged spread games to maturity.  Risk parity if practiced on a large scale will produce wipeouts akin to the recent crisis.</p> ]]></content:encoded> <wfw:commentRss>http://alephblog.com/2012/02/04/against-risk-parity/feed/</wfw:commentRss> <slash:comments>5</slash:comments> </item> <item><title>Industry Ranks February 2012</title><link>http://alephblog.com/2012/02/04/industry-ranks-february-2012/</link> <comments>http://alephblog.com/2012/02/04/industry-ranks-february-2012/#comments</comments> <pubDate>Sat, 04 Feb 2012 14:49:53 +0000</pubDate> <dc:creator>David Merkel</dc:creator> <category><![CDATA[Industry Rotation]]></category> <category><![CDATA[Portfolio Management]]></category> <category><![CDATA[Quantitative Methods]]></category> <category><![CDATA[Stocks]]></category> <category><![CDATA[Value Investing]]></category> <guid

class="wp-caption-text">Industry-Ranks-2-2012</p></div><p>I’m working on my quarterly reshaping — where I choose new companies to enter my portfolio.  The first part of this is industry analysis.</p><p>My main industry model is illustrated in the graphic.  Green industries are cold.  Red industries are hot.  If you like to play momentum, look at the red zone, and ask the question, “Where are trends under-discounted?”  Price momentum tends to persist, but look for areas where it might be even better in the near term.</p><p>If you are a value player, look at the green zone, and ask where trends are over-discounted.  Yes, things are bad, but are they all that bad?  Perhaps the is room for mean reversion.</p><p>My candidates from both categories are in the column labeled “Dig through.”</p><p>If you use any of this, choose what you use off of your own trading style.  If you trade frequently, stay in the red zone.  Trading infrequently, play in the green zone — don’t look for momentum, look for mean reversion.</p><p>Whatever you do, be consistent in your methods regarding momentum/mean-reversion, and only change methods if your current method is working well.</p><p>Huh?  Why change if things are working well?  I’m not saying to change if things are working well.  I’m saying don’t change if things are working badly.  Price momentum and mean-reversion are cyclical, and we tend to make changes at the worst possible moments, just before the pattern changes.  Maximum pain drives changes for most people, which is why average investors don’t make much money.</p><p>Maximum pleasure when things are going right leaves investors fat, dumb, and happy — no one thinks of changing then.  This is why a disciplined approach that forces changes on a portfolio is useful, as I do 3-4 times a year.  It forces me to be bloodless and sell stocks with less potential for those with more potential over the next 1-5 years.</p><p>I like some technology names here, some energy some healthcare-related names, P&amp;C Insurance and Reinsurance, particularly those that are strongly capitalized.  I’m not concerned about the healthcare bill; necessary services will be delivered, and healthcare companies will get paid.</p><p>A word on banks and REITs: the credit cycle has not been repealed, and there are still issues unresolved from the last cycle — I am not interested there even at present levels.  The modest unwind currently happening in the credit markets, if it expands, would imply significant issues for banks and their “regulators.”</p><p>I’m looking for undervalued and stable industries.  I’m not saying that there is always a bull market out there, and I will find it for you.  But there are places that are relatively better, and I have done relatively well in finding them.</p><p>At present, I am trying to be defensive.  I don’t have a lot of faith in the market as a whole, so I am biased toward the green zone, looking for mean-reversion, rather than momentum persisting.  The red zone is pretty cyclical at present.  I will be very happy hanging out in dull stocks for a while.</p><p><strong>P&amp;C Insurers and Reinsurers Look Cheap</strong></p><p>After the heavy disaster year of 2011, P&amp;C insurers and reinsurers look cheap.  Many trade below tangible book, and at single-digit P/Es, which has always been a strong area for me, if the companies are well-capitalized, which they are.</p><p>I already own a spread of well-run, inexpensive P&amp;C insurers &amp; reinsurers.  Would I increase the overweight here?  Yes, I might, because I view the group as absolutely cheap; it could make me money even in a down market.  Now, I would do my series of analyses such that I would be happy with the reserving and the investing policies of each insurer, but after that, I would be willing to add to my holdings.</p><p>Do your own due diligence on this, because I am often wrong.  One more note, I am still not tempted by banks or real estate related stocks.  I am beginning to wonder when the right time to buy them as a sector is.  As for that, I am open to advice.</p><p><strong>Implications</strong></p><p>So, given that the Industry Rank categories above come from Value Line, I went to their stock screener, selected the industries, and asked for all of the companies that:</p><ul><li>are in their top 5 (of 9) categories for balance sheet strength, and</li><li>their horribly overworked analysts think can return at least 15%/yr over the next 3-5 years.</li></ul><p>This combines safety, growth potential, valuation, and in my view, how promising industry prospects are.  Here are the results:</p><p>ABC ADM ADTN AKAM ALL AMAT AMX AOL APOL ARB ARRS BIDU BRKR BX CAH CBEY CECO CELL CKP CL CNQ CPB CPSI CREE CTRP DNR DRIV DV EBAY EDU EFX ERIC ESI FST GMCR GOOG HCC HRC IN INFA INTC ISIL ITRI IVC JNPR K KKR KR LIFE LRCX LTRE MASI MCHP MDCI MKC NFLX NIHD NILE NOK NTRI NVDA NXY ONNN OTEX QGEN QLGC QSII RAX RIMM RMD SHEN SOHU STM STRA SWKS SWY SYY T THG TMO TNDM TRH TRI TSM TSRA TUP TXN UNTD UPL UTHR VOD VOLC VZ WBMD WBSN YHOO ZBRA</p><p>When I do my next portfolio reshaping for clients in the next week or so, these stocks (and a few others) will compete against the 35 existing portfolio names for the 34-36 slots in the portfolio.</p><p>Full disclosure: Long HCC, INTC, THG, VOD</p> ]]></content:encoded> <wfw:commentRss>http://alephblog.com/2012/02/04/industry-ranks-february-2012/feed/</wfw:commentRss> <slash:comments>0</slash:comments> </item> <item><title>We Eat Dollar Weighted Returns &#8212;

The rest of the risk stems from speculation.</p><p>I am a fan of junk bonds when nobody likes them, but there are too many fans now, and for bad reasons, most of which boil down to &#8220;I am old and I need income.  The fed has eliminated good choices for income, but I need income anyway, so get me yield.&#8221;</p><p>I had a conversation with a friend of mine in her upper 70s today where she asked &#8220;why are you suggesting I sell my funds that provide the most income?&#8221;  I said that I did not trust junk bonds at present and would look to lighten up, besides, the fund she owned has underperformed over the last 10 years.  If she really wanted income from junk bonds, I would look for a new fund for her.  So I am looking for a new HY fund, with an arm twisted behind my back.  It&#8217;s not the right idea, but she won&#8217;t listen.  (She&#8217;s not paying me.  I help my friends as best I can.)</p><p>The illusion of yield drives many older investors; they need income, and the delusional Fed thinks that low yields will yield prosperity.  It may make some people take more risk, but it will not yield prosperity.  There will be a lot of impoverished old people at the end of this, and they will be angry &#8212; at themselves, their advisors,  and the powers that be.</p><p>-==-=-=&#8211;=-==&#8211;=-=-=-=-=-=-=-==&#8211;=-=-=-=-=-=-=-=</p><p>This is not to say say that junk spreads are low; they are moderate to high at present.  But the spread relationship is manipulated by the Fed at present, making spreads seem high.  No market is truly free, but the Treasury market is affected by the Fed to a high degree.  The high quality bond market follows Treasuries closely.  Junk bonds don&#8217;t.  Junk bonds follow a hybrid of what Treasuries and common stocks are doing.  With stocks doing well, junk bonds run as well.</p><p>But we are still in an environment where more things can go wrong than right.  Until the US government figures out how to finance itself, we are in dangerous territory.  Given present political conditions, I don&#8217;t see how that works out; everything looks like a stalemate at present.</p><p>So be wary, and don&#8217;t overcommit to risk assets.  I would be neutral on risk assets at presemt, but ready to be bearish if there are problems in Europe or China.</p><p>&nbsp;</p><p>&nbsp;</p> ]]></content:encoded> <wfw:commentRss>http://alephblog.com/2012/01/27/on-junk-bonds/feed/</wfw:commentRss> <slash:comments>8</slash:comments> </item> <item><title>Against Simple Valuation Metrics</title><link>http://alephblog.com/2012/01/24/against-simple-valuation-metrics/</link> <comments>http://alephblog.com/2012/01/24/against-simple-valuation-metrics/#comments</comments> <pubDate>Tue, 24 Jan 2012 08:47:48 +0000</pubDate> <dc:creator>David Merkel</dc:creator> <category><![CDATA[Portfolio Management]]></category> <category><![CDATA[Quantitative Methods]]></category> <category><![CDATA[Stocks]]></category> <category><![CDATA[Value Investing]]></category> <guid

Finance, and they have some canned and wrong way of identifying competitors.</p><p>Avoid these articles, and instead, look for some degree of qualitative reasoning &#8212; some depth that shows genuine industry knowledge, and not an ability to automate the provision of web &#8220;content.&#8221;</p><p>-=-=-=- end rant mode -=-=-=-</p><p>Maybe I should be quiet.  After all, the provision of bad advice on the web is a good thing for me.  The more people are misled, the better value investors with broader skill sets do.</p><p>But that&#8217;s not why I started writing on investments.  I was not a professional investor until I turned 39.  I read widely, and spent a lot of time reading the works of many different investors as I worked to develop a theory that encompassed most of it.  No, I don&#8217;t see how to encompass all of it&#8230; and what I can encompass is understood with some amount of error.</p><p>My view as I write is not so much to give &#8220;buy this&#8221; or &#8220;sell this&#8221; ideas so much as to get people to think differently about investing.  I recently looked at the amount of business/economics/finance/investment books that I have read over the past 25 (post-academic) years, and it would fill 3-4 bookcases.</p><p>So try to think of the companies that you own, or might own, like businesses.  Look at the dividends, and to buybacks at bargain prices, and analyze sustainability and growth prospects, but also look at opportunities for growth.  Many aspects of value can&#8217;t be encapsulated in simple ratios or rankings, but sadly, the majority of articles touting stocks will do just that, and for the most part, they are useless.</p><p>There.  I said it.  But it needs to be said.  The practical question to me is whether I should stop submitting my content to sites like Seeking Alpha, which to me have become a lot of noise, and which I wish I could get Yahoo! Finance to allow users to filter out of the news stream.</p><p>I let almost anyone republish my content, so dropping anyone would be unusual for me.  Or, should I drop all external users of my content, and allow no republishing?  If you have a strong opinion, submit it in the comments.  I&#8217;ve been a nice guy with all of this, but if you have good reasons for exclusivity, let me know, and I will consider it.</p><p>But to close I will say, look at a full range of valuation and performance metrics when buying a stock, and consider the industry dynamics to understand what matters most given the maturity of the industry.  That takes some work, but guess what?  Working intelligently and hard leads to better profits in investing.</p> ]]></content:encoded> <wfw:commentRss>http://alephblog.com/2012/01/24/against-simple-valuation-metrics/feed/</wfw:commentRss> <slash:comments>9</slash:comments> </item> <item><title>The Rules, Part XXIX</title><link>http://alephblog.com/2012/01/20/the-rules-part-xxix/</link> <comments>http://alephblog.com/2012/01/20/the-rules-part-xxix/#comments</comments> <pubDate>Fri, 20 Jan 2012 06:23:26 +0000</pubDate> <dc:creator>David Merkel</dc:creator> <category><![CDATA[Banks]]></category> <category><![CDATA[Bonds]]></category> <category><![CDATA[Macroeconomics]]></category> <category><![CDATA[public policy]]></category> <category><![CDATA[Quantitative Methods]]></category> <category><![CDATA[Real Estate and Mortgages]]></category> <category><![CDATA[The Rules]]></category> <guid

They hate them because they are a convenient target, and most people don&#8217;t understand what they do. Rating agencies provide opinions. Nothing more, nothing less.</p><p>Many people would like to get rid of the rating agencies. But it&#8217;s not that easy. Regulators outsource their credit rating function to the rating agencies because they don&#8217;t want to do that work.</p><p>There is a way to eliminate the rating agencies, and I have written about that before. But the idea is so radical, that the banks would rather have the rating agencies exist, than use my idea.</p><p>So what&#8217;s my idea? Simple. If you were setting up a portfolio, what would you assume would be the minimum that you could earn on the portfolio? My minimum would be buying Treasury bonds and earning interest on them.</p><p>So if I am looking at a portfolio of risky assets, I would split each asset into two. I would mirror the cash flow pattern of each asset, and construct an equivalent Treasury portfolio to mimic the cash flows. All of the cash flows above that amount from the risky asset are the risky cash flows. The amount of capital that banks hold as reserve against losses should be proportionate to the present value of risky cash flows.</p><p>Unlike my last piece on this, I am not saying that the whole present value of risky cash flows should be held as capital against losses. But the regulators should use this, if we are not using rating agencies, as a proxy for credit risk in bank asset portfolios.</p><p>Why is this a good measure of credit risk inside banks? The market for lending is fairly efficient. Debts that have more risk have higher interest rates.</p><p>This measure of risk benefits from the concept of simplicity. It can be applied everywhere. And, there is good theoretical justification for it. Any return that is upon the government bonds is subject to question.</p><p>But suppose we decided to use this as a major portion of our formula for regulating bank capital. What would happen to monetary policy?</p><p>Well, if the Fed tries to do something similar to “operation twist&#8221; it would require banks to hold more capital against their positions, because the safe interest rate falls, it causes the risky portion of each loan to rise. As such, any sort of “operation twist&#8221; would fail, because the rise in capital levels, would blunt any advantage from over Treasury interest rates.</p><p>From my vantage point, it would be a real plus to have monetary policy neutered in that way. The Fed, should it deserve to exist, should be concerned with the banking system and its solvency. It should not be concerned with the overall level of interest rates. If lowering interest rates lowers the judgment of solvency, then that would restrain the Fed from being too aggressive in lowering rates. And that would be good. The Fed has generally not succeeded with monetary policy. They have been too loose in the past, leading to the problems of the present.</p><p>And, as I have said before, we should not have unelected bureaucrats driving our economy, rather, we should have Congress do it because we can vote them out.</p><p>That&#8217;s all for now. Thanks for reading me. I appreciate all of my readers.</p> ]]></content:encoded> <wfw:commentRss>http://alephblog.com/2012/01/20/the-rules-part-xxix/feed/</wfw:commentRss> <slash:comments>2</slash:comments> </item> <item><title>On Predicting the Future, Redux</title><link>http://alephblog.com/2012/01/20/on-predicting-the-future-redux/</link> <comments>http://alephblog.com/2012/01/20/on-predicting-the-future-redux/#comments</comments> <pubDate>Fri, 20 Jan 2012 05:29:56 +0000</pubDate> <dc:creator>David Merkel</dc:creator> <category><![CDATA[Macroeconomics]]></category> <category><![CDATA[Quantitative Methods]]></category> <guid
