THE STONES ON THE BLACK EARTH

Civil war over unpaid debt was a real possibility in Athens by around 594 BC. Farmers who had fallen behind had put up their own land as security for what they owed, and the ones with nothing left to offer had put up their own bodies instead, so that the day a debt went unpaid was also the day a person became property. Athens responded by giving one man, Solon, a degree of authority the city had never handed anyone before, hoping he could settle the quarrel before it tore the place apart. He held the office of archon, chief magistrate of Athens, though the citizens leaned on him mainly as a mediator brought in from outside the fight, trusted by neither side completely and by both sides just enough.

History came to call his reform the seisachtheia, a Greek word usually translated as the shaking-off of burdens. Solon’s own verses on the subject survive in part because a later writer quoted them in what remains of the Athenian Constitution attributed to Aristotle’s school, and in them he boasts, with no false modesty at all, of pulling the horoi, the stone markers that recorded a debt against every mortgaged field, out of the ground himself, until the earth that had been enslaved alongside its farmers was free of them too. He also cancelled the debts outright, freed everyone already enslaved for failing to pay one, and banned any future loan secured on a borrower’s own body. Creditors who had been expecting repayment in full almost certainly told a less flattering version of the same events. Later Greek writers nonetheless remembered Solon as one of the Seven Sages, a reputation resting mainly on the simple, durable fact that he had walked away from the whole affair without a war breaking out behind him.

The quarrel between creditor and debtor is considerably older than any central bank, and it persists today in barely altered form, carried forward through a different instrument. Today that same argument runs through a single published number, read out several times a year at a press conference, dressed in language borrowed from engineering rather than from any argument about justice.

A single rate change produces two completely different biographies out of the same morning’s announcement. When the rate rises, a saver’s deposit finally earns something again, and anyone living on a fixed income breathes a little easier. The same morning, a household carrying a variable mortgage, or an employer carrying a bank loan, feels that same announcement less like news and more like a belt pulled one notch tighter around the chest. Nobody involved voted on which biography they would get.

Cutting the rate runs the same machine in reverse. Mortgage payments fall, a struggling business finds it easier to refinance a loan that was about to break it, and a government carrying its own debt pays less to service it. The saver living on the interest from a lifetime of deposits watches that same income shrink, often just as retirement removes any remaining chance to earn more elsewhere. Every cut that rescues one household is quietly paid for by another household that did nothing wrong except hold its wealth in the particular form the cut happens to penalise.

American history has its own version of Solon’s farmers, organised and loud rather than quietly facing slavery for debt. William Jennings Bryan built an entire presidential campaign in 1896 on the side of indebted farmers, who wanted easier money and the inflation that would come with it to erode what they owed, against creditors and bankers who wanted the currency kept hard and the debts repaid in full value. He lost the election, but the underlying argument, whether money should be managed to favour whoever owes it or whoever is owed it, simply relocated a few decades later into a room with a very different set of furniture.

Paul Volcker took the saver’s side of that ledger more decisively than any Federal Reserve chairman before or since. From late 1979 he pushed the key American interest rate to levels nobody alive had seen, eventually touching close to twenty per cent, specifically to break an inflation that had been running for most of the decade. Builders and contractors, unable to sell a single house at mortgage rates that high, took to posting him two-by-four studs through the mail, a protest built from lumber nobody could afford to turn into a house any longer.

That inflation, the one Volcker spent the early 1980s breaking, traced back to a specific decision a decade earlier. President Nixon had leaned hard on his own Federal Reserve chairman, Arthur Burns, to keep rates low heading into the 1972 election, reportedly threatening legislation that would have curtailed the Fed’s independence if Burns refused. Burns largely gave way. Inflation, already a live concern at the time, went on to get substantially worse across the rest of the decade, which is roughly the bill Volcker was handed a few years later.

Independence exists, in its current form, mainly because of stories exactly like that one. Central banks in most developed economies have been deliberately placed one awkward step removed from whoever is currently facing re-election, precisely because an elected official given direct control of the one lever that can make borrowing cheap right before a vote would, with depressing reliability, find the lever too tempting to leave alone.

Solon arrived at roughly the same insight some twenty five centuries earlier, by a different route. Having bound the Athenians by oath to keep his new laws unchanged for ten years, he then left Athens for that same decade, travelling as far as Egypt and Lydia, specifically so that no one, including himself, could talk him into quietly repealing what he had just written. He removed the one person capable of revising the rule from the argument about whether to revise it.

Modern independence achieves the same effect through the job’s structure itself, with no actual holiday required. Governors of the United States Federal Reserve serve staggered fourteen-year terms, considerably longer than any single president’s own time in office, specifically so that no single election can ever install a majority of the people setting the rate. This insulation runs on statute and the calendar, and the underlying instinct behind it, remove the rule-maker from the immediate reach of whoever most wants the rule changed this quarter, is exactly Solon’s.

New Zealand went further than any of them and simply gave the lever away: the Reserve Bank of New Zealand Act, passed in 1989, wrote price stability into the governor’s own job description and made him personally accountable for missing it, regardless of which party held office, a reform driven partly by years of concern that monetary policy had been too easy for strong-willed governments to lean on. The country is now generally credited with pioneering the complete, modern form of inflation targeting, copied since by central banks across the developed world, on the calculation that a currency people trusted to resist short-term pressure was worth more than a lever kept within easy reach.

Central bankers have no equivalent exit available to them. There is no decade abroad, no Solon’s holiday from the argument. A rate-setting committee meets again every six weeks or so, indefinitely, and each meeting reopens the identical quarrel between the saver and the borrower that Solon settled, for one city, with a single afternoon of pulling stones out of the ground.

None of this is entirely theatre. Transmission mechanisms, lag structures and a theoretical neutral rate are all real, measurable features of how a rate change actually moves through an economy, and the central bankers who study them are doing genuine technical work. The underlying decision is still a transfer from one group of citizens to another, now carried out through genuinely technical machinery where a magistrate once pulled stones from the ground by hand.

This transfer shows up fastest in the price of existing debt itself. A pension fund holding last year’s bond at last year’s coupon watches its price fall the instant a better one is issued, a mechanical repricing that happens within minutes of the announcement and hands a loss to the fund’s members that nobody there voted for either.

Quantitative easing extended the same redistribution through a different mechanism, on a far larger scale, across the major central banks’ response to the 2008 crisis and the pandemic that followed it. Buying enormous quantities of government bonds and other assets pushed their prices up and their yields down, which supported the wider economy but also lifted the value of shares, property and anything else priced relative to a government bond, overwhelmingly for the benefit of whoever already owned those assets before the purchases began. Nobody who held no assets at all received any direct transfer through that particular channel; the mechanism simply has no instrument for reaching them. Pension funds, insurers and ordinary savers absorb this every time the number moves, usually without ever being told that is what just happened to their statement.

Somewhere this afternoon, a young couple is signing a variable-rate mortgage without reading the clause about what happens if the rate resets higher, and an elderly saver two streets away is quietly relieved that her building society account finally pays something worth checking again. Neither of them attended the press conference that decided which of those two mornings they would be having. Both of them are living inside an argument that started, as arguments about debt generally do, with somebody’s land.
