Professor Charles Goodhart of the London School of Economics explains the difference between inflation targeting and price level targeting in the lobby of Jackson Lake Lodge after taking part in an animated discussion of whether central banks should target price levels rather than inflation.

A paper University of California, Santa Cruz economist Carl Walsh presented at the Federal Reserve’s annual mountain retreat suggested that one lesson from the recent financial crisis is that central banks would benefit from the greater flexibility that price level targeting might give them.

A former Fed governor,  Frederic Mishkin, said that while in theory price level targeting may sound attractive, in actual practice it is more difficult to use effectively. One difficulty he cited was in explaining to consumers how it works. 

 Juergen Stark of the inflation-targeting European Central Bank, said that inflation targeting was working well for the ECB, and that changing tactics in a crisis would be inappropriate.

Five things to think about this week:

APPETITE TO CHASE? 
- Equity bulls have managed to retain the upper hand so far and the MSCI world index is up almost 50 percent from its March lows. However, earnings may need to show signs of rebounding for the rally's momentum to be sustained. Even those looking for further equity gains think the rise in stock prices will lag that in earnings once the earnings recovery gets underway, as was the case in past cycles. The symmetry/asymmetry of market reaction to data this week -- as much from China as from the major developed economies -- will show how much appetite there is to keep chasing the rally higher. 

TAKING CONSUMERS' PULSE 
- A better picture of the health of the consumer will emerge this week as U.S. retailers' earnings coincides with the release of U.S. July retail sales data and the UK BRC retail survey comes out on the other side of the Atlantic. With joblessness still rising, the reports will show how willing households are to spend and whether deep discounts, which eat into retailers' profit margins, are the only thing that will tempt them to shop -- both key issues for the macroeconomic and corporate outlook. 

CENTRAL BANK WATCH 
- After last week's Bank of England surprise, all eyes turn to what sort of signals the U.S. Federal Reserve and Bank of Japan will send on the outlook for their respective economies and QE programmes. After the BOE's expansion of its QE programme the short sterling strip repriced how soon UK rates would rise. But the broader trend recently in the U.S., euro zone and the UK has been to discount rate rises in 2010 -- and possibly as soon as this year in Australia. Benchmark interbank euro rates have risen for the first time in two months, and central bankers everywhere, including China, face the delicate balancing act of managing monetary tightening expectations in the months ahead. 

PRICE PROTECTION
-This week's inflation data (from Germany, France, Italy, euro zone, U.S.) is unlikely to contain any nasty surprises. But the U.S. Treasury's willingness to consider bringing back the 30-year TIPS suggests that enough investors and reserve managers are looking beyond current subdued price data to future inflation risks from QE programmes, etc. That will ensure a close eye is kept on breakevens and whether the main issuers of inflation-linked products in the euro zone are inclined to increase issuance of such products.

TRADE 
- Official resistance to currency appreciation has been evident in some developed countries (Switzerland, RBA, RBNZ, among others) and there are suspicions that some Asian central banks may also be inclined to check such trends given the fierce competition among the world's exporters to grab what orders there are. Trade data this week will show how trade flows are faringand the extent to which Chinese economic activity is driving them.

Central bankers have not had much reason to be happy over the last two years, as the financial crisis has lurched from bad to worse.

But the European Central Bank at least is now finding comfort in the fruits of its injection of close to half a trillion euros in 12-month funds last week, which has pushed money market interest rates to new record lows. 

“We are very happy, we see clearly that we decreased the risk premia,” ECB President Jean-Claude Trichet said on Thursday, after the ECB kept its benchmark rate on hold at 1 percent.

Still, the ECB’s generosity in filling bank coffers with cheap cash could paradoxically help financial institutions defer the day of reckoning when they will have to write down bad loans and toxic assets on their books, and adjust their balance sheets. Flush with ECB cash, banks could be encouraged to think they can hang on to past investment mistakes, rather than writing them down now. 

The Swiss-based Bank for International Settlements, a forum for the world’s central banks, says this painful process is a prerequisite for financial and economic recovery, and the International Monetary Fund  says the euro zone is lagging the United States in writedowns.

Maybe the ECB is not helping.

Five things to think about this week:

STALLING RALLY
- The global equity market rally has stalled in June and is threatening to go into reverse. With this week effectively the last full week of the second quarter, the temptation for many funds to book profits on such a lucrative quarter will be high. Any knock on boost to volatility would pose more risks for some of the trades that looked the most attractive in a lower volatility environment, such as cyclical versus defensives plays, emerging markets, and foreign exchange carry trades.

POLICY, SUPPLY RISKS FOR BONDS
- How the U.S. Federal Reserve will respond to the interest rate market gyrations of the past month has been a key market talking point. Questions centre on whether it will expand the size of buybacks, whether there will be any change in the length of time the buyback programme lasts, whether the central bank makes any effort to unwind the rise in bond yields seen in the past months, and whether there will be any talk of an exit strategy. Another risk to the front end will be the Treasury refinancing, which resumes after a week of no supply and will be concentrating on the shorter end.

WHAT COLOUR ARE THE SHOOTS
- This week's data will show both whether the inventory rebuilding that was priced in over recent months is actually materialising and whether there are any other drivers of economic activity out there. The flash PMI in Europe and sentiment indicators will be particularly relevant in deciding on the latter issue, with consumer and income data out from both sides of the Atlantic providing an additional window on how domestic demand is shaping up.

CENTRAL BANK CASH
- There is potential for significant take up at the ECB's first one-year tender this week and some are speculating that the injection of large amounts of money into the market could drive down short end rates sharply. Most recent anecdotal evidence suggests firms are still facing tight credit conditions but confidence in financial stabilisation is a pre-requisite if banks are to lend on. This is leading to speculation of where else the money might be parked in the interest rate or fixed income universe. There are also question marks over whether any of the money might leak outside the euro zone -- and what, if any, are the potential FX implications of such seepage.

EMERGING MARKET RISKS
- Higher volatility spells underperformance in the emerging market universe and has raised questions over the risks in individual countries -- e.g. Turkey's IMF deal; Latvia's political difficulties in winning acceptance for budget cuts; the possibility of the Iranian domestic upheaval gaining market attention; and ructions within the Saudi banking sector. The shifting sentiment suggests potential hurdles for heavy third quarter corporate and government refinancing needs, especially in central and eastern Europe, not least given that the heavy issuance plans of better-rated developed market sovereigns pose crowding out risks.

Five things to think about this week:

BOND YIELDS 
- Nominal bond yields have risen across the curve, while term premiums and fixed income volatility are higher in an environment of uncertainty about how central banks will exit from quantitative easing policies once recovery takes hold. Bonds have turned into the worst-performing asset class this year according to Citi and none of the factors which markets have blamed for this are about to disappear. Curve steepening seen in April/May has started to reverse and whether it continues is being viewed as a more open question than whether yields head higher still.

RATTLING EQUITIES? 
- World stocks’ are struggling to extend the near-50 percent gains seen since March 9 but they have yet to succumb to gravity despite a back up in government bond yields. Citigroup analysts reckon global equity markets can rally as long as Treasury yields stay below 5-6 percent but it might be the speed of yield moves that determines whether equities get rattled or keep looking past higher borrowing costs to the recovery story. 

INFLATION EXPECTATIONS 
-  Increases in the prices of oil and other commodities have seen the CRB index rise about 30 percent in less than four months and sustained gains will risk filtering through to prices and price expectations. Inflation reports are due out on both sides of the Atlantic next week but markets are looking further out and starting to price in the risks of a pick up in price pressures. Breakevens have turned positive all along the U.S. yield curve for the first time since autumn and euro zone breakevens have risen. Also, a Bank of England survey indicates public price expectations are up. Bid/cover ratios and tails at inflation-linked bond auctions will tell their own story on extent of demand for inflation hedges.

CENTRAL BANK POLICY 
- Futures pricing after the U.S. non-farm payrolls showed the ebbing and flowing of rate rise expectations in the U.S. and UK and a feedback loop is increasingly evident between markets, which are keenly attuned to every nuance of how QE exit strategies might play out, and policymakers, who are puzzled by what drove the dramatic swing in rate rise expectations and what is pushing up bond yields. Policymakers are treading a fine line between actions (pursuing QE) and anti-inflation rhetoric, and central bank reports (BOJ), policy meeting minutes (BOE, BOJ), and SNB policy meetings will shed more light on how they plan to manage this tightrope act. 

BRIC POWER 
-  FX reserve plans, IMF financing, and the nature of the new IMF bond are on financial markets’ radar in the run-up to the first BRIC summit that will be held in Russia this week. How much the big emerging powers can agree on and how much unity they show at their first such summit will shape expectations of how much they can influence international policy and the market fallout of any proposals they table.

Five things to think about this week:

VOLATILITY
- World stocks' near-50 percent gain since early March may be levelling off -- investors have factored in much of the output recovery that is in the pipeline and fresh impetus could be needed from further improvements in economic indicators or the corporate outlook. With many fund managers yet to wade in with the cash piles on which they have been sitting, a bout of volatility looks more likely than a dramatic pullback.

GROUP OF 8
- Talk of green shoots of economic recovery has removed some of the threat of global economic meltdown and therefore reduced the pressure to come up with coordinated international policy response. The Lecce finance ministers' meeting will test G8 nations' commitment to putting up extra money for the IMF and an SDR allocation increase. The risk is that cracks appear on these and other issues (eg QE, fiscal stimulus, etc). Given expanded IMF resourcing was one of the planks on which the equity market/emerging market rebound was built, any signs of pullback could fuel volatility and throw up risks for the assets which have benefited most from that rally.

DOLLAR STANCE
- Asian reserve managers' reassurance on Treasuries holdings came in the same week as rumblings of discomfort from some emerging market countries (eg South Africa, Israel) on the dollar's slide and its fallout. Soothing noises from Asia about their dollar-denominated holdings and its FX impact risk being cancelled out by the chatter about international reserve currencies building in the run-up to the first BRIC summit later in June.

BALTICS AND THE FALLOUT
- How much international help Latvia gets to fend off devaluation pressures will determine fate of assets well beyond its own borders. CEEU assets as well as Nordics are affected by fallout and the ripple effects have been seen in euro zone countries with biggest exposure to Baltics and its banking sector.

DEBT ABSORPTION
- Strong demand for long-dated German and UK debt helped reverse part of the recent yield curve steepening. Fed, ECB and market watchers are having a hard time disentangling how much of that steepening was down to economic activity pick up expectations and how much should be attributed to issuance, longer-term price pressure concerns. The market's appetite to absorb more long-dated paper (from U.S. and Japan this week) will shed more light on how soon central banks might have to fret about longer-term borrowing costs backing up.

Five things to think about this week:

EYE ON CENTRAL BANKS
-  Investors will be on the lookout for any further signals on quantitative easing when the European Central Bank and the Bank of England announce their decisions on Thursday. Analysts see the ECB leaving rates on hold but pushing ahead with and possibly extending a plan to buy up to 60 billion euros in covered bonds. The focus will also be on growth forecasts for the next year and the message they send about the pace of any recovery.

COMMODITIES SUPERCYCLE, CYCLICAL SURGE
- Oil prices are nearly double their four-year low set in December and the Baltic Dry Index, which tracks rates to ship dry commodities, has risen more than 300 percent since the start of the year. Coupled with a weakening dollar, investors might be bracing for the return of the supercycle in commodities. The resultant inflationary pressures could push investors away from government bonds and into the arms of equities.

EMERGING DISCONNECT
- High-yielding emerging market currencies remain weak, weighed down by poor domestic growth prospects even as emerging equities rise along with their developed market peers, buoyed by hopes of a global economic recovery. The disconnect is likely to persist with governments, particularly in emerging Europe, looking likely to lower interest rates further.

IN SEARCH OF MORE POSITIVE DATA
- Green shoots have been popping up at an encouraging rate, with consumer confidence and home sales data in the United States, and improved Euro zone economic sentiment being the latest signs that a downturn may not be as steep as many originally feared. The week provides more key tests for this hypothesis: U.S. non-farm payrolls, core personal consumption expenditure, factory orders and ISM data.

TREASURY YIELDS
- A sharp rise in Treasury yields driven by worries over a record U.S. budget deficit has pushed the yield curve to its steepest on record, and Treasuries yielded more than euro zone government bonds for the first time in seven months. While surging yields could threaten the equities rally as businesses and consumers fret about increased borrowing costs, auctions attracted strong buying from foreign central banks, putting a floor under the dollar.

Five things to think about this week:

VALUATIONS
- The MSCI world stocks index has rebounded 37 percent since March, the VIX fear gauge has hit its lowest level since September 2008, and positive earnings surprises in Europe are marginally outstripping negative ones. But there are serious questions over the equity market's ability to sustain its rise.

MACRO SIGNALS
- Trade data from the U.S., Canada and the UK, all out in this week, will be combed for signs of any recovery in global commerce. Also due are flash GDP data from the euro zone, industry output for the U.S., France, Italy, the euro zone and the UK, and Japan machinery orders.  
  
QUANTITATIVE EASING
- The ECB has finally shown willingness to deploy unconventional easing measures but it's hard to judge the success of such steps. Narrowing credit spreads, stock markets' bounce and gains in emerging market assets all show efforts to restore confidence in the financial system are having an effect. But if getting and keeping bond yields down is the yardstick for success, it's unfortunate that 10-year UK and U.S. government bond yields are back up to levels seen before the announcement of quantitative easing in those countries. And diminishing returns on further balance sheet expansion raise questions over how much more money central banks can print before inflation fears start to preoccupy policymakers and markets.
  
COMMODITIES
- Confusion over the reasons for the commodities rally has reduced the usefulness of commodities prices as indicators of the industrial outlook. An apparent economic recovery in China has helped to boost the CRB commodities index by 21 percent from February's lows. But how much does the rise reflect a change in supply/demand for commodities, and how much is it simply due to idle money flooding back to unstable markets? Similarly, why has spot gold remained strong above $900 as jitters over the financial system decrease? Gold could be reflecting expectations that recovering economies will boost physical demand for the metal, but it may also be responding to fears of currency debasement after central banks' radical monetary easing.

EMERGING MARKETS 
- Rising commodity prices and an easing dollar have offered a perfect environment to re-enter emerging markets. The coming week's  EBRD meeting will focus attention on central and eastern Europe and how it is coping with a nasty period of refinancing (albeit less dire than the IMF initially estimated).
