    How to win the battle against inflation

    Over the past year we have examined the economic fortunes of Hikelandia. In this group of eight countries—Brazil, Chile, Hungary, New Zealand, Norway, Peru, Poland and South Korea—central banks have fought inflation with unparalleled aggression. Hikelandia started raising interest rates a whole year before America’s Federal Reserve, putting it well ahead of the curve. Since then its average policy rate has risen by more than seven percentage points, compared with around five for the Fed. Yet for months Hikelandia’s central bankers had little joy: inflation kept rising.Now, at long last, that is changing. Although Hikelandia’s “core” inflation, a measure that strips out volatile prices such as for food and energy, is still too high, at around 9% year on year, it is on the way down, in part because higher rates are starting to bite (see chart). Hikelandia’s experience offers a glimmer of hope for other inflation-fighting central banks.Wage inflation is moderating across the land. In Chile, for example, pay growth is down a little from the outrageously high 11% year-on-year rate reached in January. This, in turn, is helping cut measures of inflationary pressure. In October South Korea’s inflation rate in the labour-intensive service sector was 4.2% year on year; it has since fallen to 3.3%. Poland’s has slipped from 13.4% in December to 12.3%.Inflation expectations are also dropping, influenced by falling energy and food prices. The average Brazilian expects inflation of 4% over the next year, down from 6% for much of 2022. Kiwis reckon inflation in five years’ time will be around 1%, half their forecast in December.Norway is the only member of Hikelandia that seems to be making no progress. In May core prices unexpectedly rose by 6.7% year on year, a new high. A weaker krone is raising the cost of imports. Strong domestic demand is playing a role, too. In June the central bank surprised markets in an attempt to cool things down, raising the policy rate by 0.5 percentage points.Outside Oslo, the mood music in Hikelandia’s central banks has changed. Officials are still talking tough, of course. South Korea’s rate-setters insist that they will maintain hawkish policy for a “considerable time”. Brazil’s monetary-policy committee worries about “a larger or more persistent de-anchoring of long-term inflation expectations”. Yet this hides the fact that Hikelandia’s central banks have largely stopped raising rates. Chile’s bank believes inflationary risks “have been balancing out”. Hungary’s rate-setters expect that “disinflation will continue to accelerate”.Success has come at a cost, though. In 2021 the world economy and Hikelandia grew at the same speed. Now, global growth is 2.5% at an annualised rate, and Hikelandia is stagnating. The unemployment rate has risen by close to a percentage point from a recent low in Chile, and is inching up in Brazil and New Zealand. At least for a while, Hikelandia’s policymakers will probably see a slower economy as a price worth paying. Inflation will have to fall an awfully long way before we start calling these countries “Cutlandia”. ■For more expert analysis of the biggest stories in economics, finance and markets, sign up to Money Talks, our weekly subscriber-only newsletter.

    Economists draw swords over how to fix inflation

    For as long as inflation has been high economists have fought about where it came from and what must be done to bring it down. Since central bankers have raised interest rates and headline inflation is falling, this debate may seem increasingly academic. In fact, it is increasingly important. Inflation is falling mostly because energy prices are down, a trend that will not last for ever. Underlying or “core” inflation is more stubborn (see chart 1). History suggests that even a small amount of sticky underlying inflation is hard to dislodge. So the chiefs of the world’s most important central banks are now warning that their job is far from done. “Getting inflation back down to 2% has a long way to go,” said Jerome Powell, chairman of the Federal Reserve, on June 29th. “We cannot waver, and we cannot declare victory,” Christine Lagarde, president of the European Central Bank, told a meeting of policymakers in Portugal just two days earlier. Andrew Bailey, governor of the Bank of England, recently said that interest rates will probably stay higher than markets expect. This means that there will be no let-up in the economists’ wars. The first front is partly ideological, and concerns who should shoulder the blame for rising prices. An unconventional but popular theory suggests greedy firms are at fault. This idea first emerged in America in mid-2021, when profit margins for non-financial companies were unusually strong and inflation was taking off. It is now gaining a second wind, propelled by the IMF, which recently found that rising profits “account for almost half the increase” in euro-zone inflation over the past two years. Ms Lagarde appears to be entertaining the thesis, too, telling the European Parliament that “certain sectors” had “taken advantage” of the economic turmoil, and that “it’s important that competition authorities could actually look at those behaviours.”Greedflation is a comforting idea for left-leaning types who feel that blame for inflation is too often pinned on workers. Yet it would be strange to think firms suddenly became greedier, making prices accelerate. Inflation is caused by demand exceeding supply—something that offers plentiful profit opportunities. The greedflation thesis thus “muddles inflation’s symptoms with its cause”, according to Neil Shearing of Capital Economics, a consultancy. Wages have tended to play catch-up with prices, not vice versa, because, as the IMF’s economists note, “wages are slower than prices to react to shocks”. That is a crucial lesson from today’s inflationary episode for those who always view economic stimulus as being pro-worker.The second front in the inflation wars concerns geography. America’s inflation was at first more home-grown than the euro zone’s. Uncle Sam spent 26% of GDP on fiscal stimulus during covid-19, compared with 8-15% in Europe’s big economies. And Europe faced a worse energy shock than America after Russia invaded Ukraine, both because of its dependence on Russian natural gas and the greater share of income that is spent on energy. A recent paper by Pierre-Olivier Gourinchas, chief economist at the IMF, and colleagues attributes just 6% of the euro zone’s underlying inflation surge to economic overheating, compared with 80% of America’s. This implies that Europe can get away with looser policy. The 3% of GDP of extra fiscal stimulus the euro zone has recently unleashed by subsidising energy bills, the authors find, has not contributed to overheating, and by reducing measured energy prices may even have stopped an inflationary mindset from taking hold. (The authors caution that things might have been different had energy prices not fallen, reducing the subsidy.) Interest rates are lower in Europe, too. Financial markets expect them to peak at around 4% in the euro zone, compared with 5.5% in America. Despite all this, inflation problems on each side of the Atlantic actually seem to be becoming more alike over time. In both places, inflation is increasingly driven by the price of local services, rather than food and energy (see chart 2). The pattern suggests that price rises in both places are being driven by strong domestic spending. Calculated on a comparable basis, core inflation is higher in the euro zone. So is wage growth. According to trackers produced by Goldman Sachs, a bank, wages are growing at an annualised pace of 4-4.5% in America, and nearly 5.5% in the euro area.Hence the importance of a final front: the labour market. Even if profit margins fall, central banks cannot hit their 2% inflation targets on a sustained basis without the demand for and supply of workers coming into better balance. Last year economists debated whether in America this required a higher unemployment rate. Chris Waller of the Fed said no: it was plausible job vacancies, which had been unusually high, could fall instead. Olivier Blanchard, Alex Domash and Lawrence Summers were more pessimistic. In past economic cycles, they pointed out, vacancies fell only as unemployment rose. Since then Mr Waller’s vision has in part materialised. Vacancies have fallen enough that, according to Goldman, the rebalancing of the labour market is three-quarters complete. Unemployment remains remarkably low, at 3.7%.Yet the process seems to have stalled of late (fresh data were due to be released as we published this article). Mr Blanchard and Ben Bernanke, a former Fed chairman, recently estimated that, given the most recent relationship between vacancies and joblessness, getting inflation to the Fed’s target would require the unemployment rate to exceed 4.3% for “a period of time”. Luca Gagliardone and Mark Gertler, two economists, reckon that unemployment might rise to 5.5% in 2024, resulting in inflation dropping to 3% in a year and then falling towards 2% “at a very slow pace”. Rises in unemployment of such a size are not enormous, but in the past have typically been associated with recessions. Meanwhile, in the euro zone, vacancies have not been particularly elevated relative to unemployment, making the route to a painless disinflation even more difficult to foresee. It is this front of the inflation wars which is most finely poised—and where the stakes are highest. ■For more expert analysis of the biggest stories in economics, finance and markets, sign up to Money Talks, our weekly subscriber-only newsletter.

    Fed sees more rate hikes ahead, but at a slower pace, meeting minutes show

    Fed officials at their June meeting decided to hold off on raising interest rates, opting for a pause to assess the impact of 10 previous hikes.
    Minutes released Wednesday indicated disagreement among members, with some saying that rates should go higher as inflation remains elevated.

    Almost all Federal Reserve officials at their June meeting indicated further tightening is likely, if at a slower pace than the rapid-fire rate increases that had characterized monetary policy since early 2022, according to minutes released Wednesday.Policymakers decided against a rate rise amid concerns over economic growth, even though most members think further hikes are on the way. Citing the lagged impact of policy and other concerns, they saw room to skip the June meeting after enacting 10 straight rate increases.Officials felt that “leaving the target range unchanged at this meeting would allow them more time to assess the economy’s progress toward the Committee’s goals of maximum employment and price stability.”Federal Open Market Committee members voiced hesitance over a multitude of factors.They said that a brief pause would give the committee time to assess the impacts of the hikes, which have totaled 5 percentage points, the most aggressive moves since the early 1980s.”The economy was facing headwinds from tighter credit conditions, including higher interest rates, for households and businesses, which would likely weigh on economic activity, hiring, and inflation, although the extent of these effect remained uncertain,” the minutes said.The unanimous decision not to raise rates came in “consideration of the significant cumulative tightening in the stance of monetary policy and the lags with which policy affects economic activity and inflation.”
    Markets showed little reaction to the release. The Dow Jones Industrial Average was off about 120 points nearing the final hour of trading while Treasury yields were sharply higher.

    Disagreement at the Fed

    The document reflected some disagreement among members. According to projection materials released after the June 13-14 session, all but two of the 18 participants expected that at least one hike would be appropriate this year, and 12 expected two or more.”The participants favoring a 25 basis point increase noted that the labor market remained very tight, momentum in economic activity had been stronger than earlier anticipated, and there were few clear signs that inflation was on a path to return to the Committee’s 2 percent objective over time,” the minutes said.Even among those favoring tightening, there was a general feeling that the pace of hikes, which included four straight 0.75 percentage point increases at consecutive meetings, would abate.”Many [officials] also noted that, after rapidly tightening the stance of monetary policy last year, the Committee had slowed the pace of tightening and that a further moderation in the pace of policy firming was appropriate in order to provide additional time to observe the effects of cumulative tightening and assess their implications for policy,” the minutes said.Since the meeting, policymakers mostly have stuck with the narrative that they don’t want to give in too quickly on the inflation fight.In remarks to Congress a week after the June 13-14 meeting, Fed Chairman Jerome Powell said the central bank has “a long way to go” to bring inflation back to the Fed’s 2% goal.He also has emphasized a united front among the 18 Federal Open Market Committee members, noting that all of them foresee rates staying at least where they are through the end of the year, and all but two see rates rising.That has been largely true, despite some misgivings. Atlanta Fed President Raphael Bostic, for instance, has said he thinks rates are sufficiently restrictive and officials can back off now as they wait for the lagged impact from the 10 hikes making their way through economy.Data also has been largely on the Fed’s side, even though inflation remains well above the target.Most recently, the Fed’s preferred inflation gauge saw just a 0.3% increase in May, though it was still reflecting a 4.6% annual rate.The labor market also has showed some signs of loosening, though job openings still outnumber available workers by a nearly 2-to-1 margin. Fed officials have stressed the importance of reducing that disparity as they look to tamp down the demand that pushed inflation higher. More

    FTC warns about student loan scams following Supreme Court decision

    The Supreme Court struck down the Biden administration’s student loan forgiveness plan Friday in a 6-3 ruling. Loan payments are poised to restart in October.
    The Federal Trade Commission warned in a consumer alert that scammers would likely target borrowers, perhaps posing as U.S. Department of Education personnel and offering loan assistance.
    The FTC offered tips for borrowers to protect themselves.

    Scammers are likely to target student loan borrowers after the Supreme Court struck down the Biden administration’s debt forgiveness plan Friday and as loan repayments are poised to restart in the fall, according to the Federal Trade Commission.
    Scammers often “take advantage of confusion around big news like this,” the FTC said in a consumer alert issued Saturday.

    “If you’re worried about repaying your loans, the offers to ‘help’ can be tempting,” the alert said. “Scammers are likely to start blasting out robocalls and texts about ‘helping’ you with your loans.”
    More from Personal Finance:Biden administration gives student loan holders payment leewaySteps student borrowers should take after Supreme Court rulingWhat Supreme Court student loan ruling could mean for economy
    The Biden administration forgiveness plan would have erased up to $20,000 of federal student loans for tens of millions of borrowers.
    Estimates suggest the student debts of about 14 million people would have been fully erased. Now, they and other borrowers must brace for monthly loan payments to restart in October, after more than three years of an interest-free pause.
    President Joe Biden said Friday after the Supreme Court’s ruling that his administration would pursue another way to deliver debt forgiveness. And when payments restart, there will also be a 12-month period during which borrowers won’t face the harshest consequences of missing payments, including default or negative marks on a credit report, Biden said.

    In the meantime, here are three ways to spot a student loan scam should a fraudster try to contact you, according to the FTC.
    1. Don’t trust anyone who promises debt relief or loan forgiveness
    Scammers try to look real, with official-looking names, seals and logos, the FTC said. They may say they’re affiliated with the U.S. Department of Education.
    “They promise special access to repayment plans or forgiveness options — which don’t exist,” the FTC said. “If you’re tempted, slow down, hang up and log into your student loan account to review your options.”
    2. Don’t give away your FSA ID login information
    Anyone who says they need your Federal Student Aid ID to help you is a scammer, the FTC said.
    “If you share it, the scammer can cut off contact between you and your servicer — and even steal your identity,” the agency wrote.
    3. Never pay for help with your student loans
    “There’s nothing a company can do that you can’t do yourself for free,” the FTC said.
    You can get help at StudentAid.gov/repay. Go directly to your loan servicer if your loans are private, the FTC said. More

    Check out the companies making the biggest moves before the bell:
    Rivian — Shares popped 6.5% in premarket trading, adding to Monday’s gains after the electric vehicle maker reported 12,640 deliveries during the second quarter. The deliveries were up 59% from the previous quarter and beat analyst expectations of 11,000 vehicles, according to StreetAccount.

    United Parcel Service — Shares of the logistics and delivery company fell more than 1% in premarket trading as negotiations between UPS and the Teamsters union appeared to hit an impasse. The union said in a statement Wednesday that negotiations had collapsed after UPS “walked away from the table.” UPS said in response that it had not walked away and was encouraging the union to return to the table. The current UPS Teamsters contract expires at the end of July.
    Coinbase — The crypto services company fell more than 2% after Piper Sandler downgraded the stock and said that, despite the recent market rally following the SEC’s lawsuit against Coinbase, the increase in crypto prices haven’t translated to an increase in trading volume. The firm also expects Coinbase to report its lowest trading volumes and monthly transacting users in over two years for the third quarter.
    AstraZeneca — The drugmaker climbed nearly 3%, after sinking 8% on Monday when AstraZeneca announced preliminary results of its phase three lung cancer treatment. The company said data for overall survival was “not mature” and results were not statistically significant, but the trial will continue. 
    Transocean — Shares of the offshore oil drilling company rose 3.7% after Citi upgraded them to buy from neutral. “We think Transocean is favorably positioned among offshore drilling peers given its sizable available fleet of idle rigs returning to work in the coming years,” Citi said.
    Hertz — Hertz shares gained more than 1% after Jefferies initiated coverage of the car rental company with a buy rating, citing the potential for stronger margins.

    American Equity Investment Life Holding — The stock added more than 2% after the company announced it will be acquired by Brookfield Reinsurance for about $4.3 billion. As part of the agreement, each AEL shareholder will receive $55 per AEL share.
    Wolfspeed — Shares soared more than 17% after the company signed a decade-long supply deal with Renesas to provide silicon carbide bare and epitaxial waters for $2 billion.

    Can anything pop the everything bubble?

    For a certain type of investor, last year came as a relief. True, the losses were grim. But at least markets were starting to make sense. Over the previous decade, central banks had pumped out floods of new money to buy bonds. Interest rates were kept unnaturally low, or even negative. The result was an “everything bubble”, a speculative mania in which valuations surged everywhere from stocks to housing to baffling crypto assets. It was never going to end well, and in 2022 it didn’t: inflation killed off cheap money; the everything bubble popped; asset prices plunged. Some were even approaching rationality. A return to reassuringly dull investing—based on fundamentals, not hype—beckoned.If this sounds familiar, and you were one of these relieved investors, you may have found yourself wrongfooted by developments over the past few months. It is not just stockmarkets, though both in America and globally they have risen to within striking distance of all-time highs. It is that risky assets across the board have proved astonishingly resilient to seemingly disastrous news. An index of American high-yield (or “junk”) bonds compiled by Bank of America suffered a peak-to-trough loss of 15% in 2022. It has since recovered half that loss. So has a similar index for junk bonds in Europe. The housing slump already shows signs of petering out, even though global prices have fallen by just 3% from their peak, or 8-10% adjusting for inflation, after a boom in which they rose at their fastest rate ever.The biggest surprise is how well even more speculative assets have held up. Bitcoin—once an emblem of the cheap-money era, seen by many as a digital token with no intrinsic value—has proved indestructible. Anyone who bought it before 2021 and held on is once again sitting on a profit, albeit just a fraction of that which they could have booked two years ago. Even sales of non-fungible tokens, records that represent pieces of digital media, were 70 times higher in 2022 than in 2020, at $1.5bn. In other words, the everything bubble in risky assets seems to have survived the return of inflation, rising interest rates, war in Europe and the threat of recession. Could anything pop it?One oft-mentioned candidate is liquidity, which is draining from the financial system. The main exit pipes run to the Federal Reserve and America’s Treasury department. The Fed is sucking out $95bn a month by allowing some of its portfolio of Treasuries and mortgage-backed securities to mature without reinvesting the proceeds. The Treasury, by one estimate, must sell $1trn of new debt during the summer to rebuild its cash buffers after Washington’s debt-ceiling stand-off.Most obviously, this depresses Treasury prices by increasing supply and removing the Fed as a monthly buyer. (Tellingly, government bonds are the one asset class to have barely recovered from last year’s shellacking.) By raising “safe” Treasury yields, this makes riskier assets relatively less attractive. It also means that investors, in aggregate, end up holding more Treasuries and less cash. As a result, they are less able to buy riskier assets even if their prices fall. The likelihood of a crash, and of it being a severe one, is therefore creeping up.Such a crash is certainly not what markets are betting on. In fact, the vix, a measure of expected stock-price volatility, often dubbed Wall Street’s “fear gauge”, has this year fallen to its lowest since before the covid-19 pandemic. Yet analysts at ubs, a Swiss bank, point out that this is less reassuring than it might appear at first glance. They find that the vix has fallen mainly because correlations between stocks are unusually low, meaning their movements cancel each other out. Should they start moving in lockstep, volatility could suddenly jump, which is what has tended to happen after past spells of low correlation.Meanwhile, as in any bubble, asset valuations have become maddeningly difficult to justify. America’s stockmarket, where the earnings yield of the s&p 500 index of major firms is now roughly level with the Fed’s risk-free rate, is the most audacious example. But it is not alone. The ubs team analysed prices across credit, commodities, stocks and currencies, backing out an implicit assumption that the world economy would grow at 3.6% per year. That is a little more than its long-term growth rate, and double its present one. Time to bet on a correction? Tempting, but perhaps more foolish than brave. Based on recent experience, everything bubbles can survive for an awfully long time.■ More
