Why Argentina Cannot Have a Normal Central Bank
为何阿根廷不能拥有一家正常的央行
In most countries, the central bank has one fundamental mandate: price stability. In Argentina, the BCRA has historically been required to perform four incompatible functions simultaneously: (1) maintain price stability, (2) finance the fiscal deficit by printing money, (3) hold sufficient reserves to defend whatever exchange rate regime is in place, and (4) control capital flows to prevent a run on the peso. These functions conflict structurally. When the government needs to finance social spending, the BCRA monetizes the deficit, undermining price stability. When reserves fall, the BCRA raises rates to attract capital, raising the quasi-fiscal cost of sterilization, generating a new debt bomb.
在大多数国家，央行有一个基本职责：价格稳定。在阿根廷，BCRA历史上被要求同时执行四项不相容的功能：（1）维持价格稳定；（2）通过印钞为财政赤字融资；（3）持有足够储备捍卫任何在位的汇率制度；（4）控制资本流动以防止比索被挤兑。这些功能在结构上相互冲突。当政府需要为社会支出融资时，BCRA将赤字货币化，破坏价格稳定。当储备下降时，BCRA提高利率以吸引资本，提高了冲销的准财政成本，制造了新的债务炸弹。
The Lebac–Leliq Doom Loop
莱巴克-莱利克死亡螺旋
Argentina's quasi-fiscal time bomb is one of the most distinctive institutional features of its monetary dysfunction. The mechanics are specific but the logic repeats: the BCRA issues high-interest short-term bonds to "sterilize" money it has printed to finance the deficit. The interest payments on these bonds are themselves financed by printing more money. The stock of sterilization debt grows faster than any conceivable tax base can service it. This creates a monetary bomb beneath any apparent stabilization.
阿根廷的准财政定时炸弹是其货币失调最具体特征性的制度特征之一。机制有特定性，但逻辑反复重现：BCRA发行高利率短期债券以"冲销"它为财政赤字融资所印制的货币。这些债券的利息支付本身由印钞融资。冲销债务的存量增长速度超过任何可设想的税基所能偿付的速度。这在任何表面稳定之下制造了一颗货币炸弹。
Lebacs (2016–18, Macri era): Macri lifted Kirchnerist capital controls and attempted stabilization via inflation targeting. The BCRA issued Lebacs (Letras del Banco Central) at rates of 25–40% to absorb pesos. By 2018, the Lebac stock was ~$30B — larger than the central bank's net reserves. A sudden rollover crisis in April 2018 triggered the capital flight that required the $57B IMF program. The Lebac resolved into the Macri crisis.
莱巴克（2016-18年，马克里时代）：马克里解除了基什内尔主义的资本管制，通过通胀目标制尝试稳定。BCRA以25-40%的利率发行莱巴克（央行短期债券）以吸收比索。到2018年，莱巴克存量约300亿美元——大于央行净储备。2018年4月突然出现的滚动危机引发了需要570亿美元IMF计划的资本外逃。莱巴克演变为马克里危机。
Leliqs (2019–23, Alberto era): The Leliq (Letras de Liquidez) replaced Lebacs as the sterilization instrument, but at even higher rates — reaching 97% annual by August 2023. The stock of Leliqs ballooned to ~$27 trillion pesos by end-2023. Milei dismantled the Leliq system in his first 100 days, replacing them with Treasury bills (Lecaps) — shifting the quasi-fiscal debt from the BCRA balance sheet to the Treasury balance sheet and eventually extinguishing it through fiscal surplus.
莱利克（2019-23年，阿尔韦托时代）：莱利克（流动性票据）取代莱巴克成为冲销工具，但利率更高——到2023年8月达到年化97%。到2023年底，莱利克存量膨胀至约27万亿比索。米莱在上任100天内拆除了莱利克体系，用国库券（Lecaps）取代——将准财政债务从BCRA资产负债表转移到财政部资产负债表，并最终通过财政盈余将其消灭。
A History of Exchange Rate Regimes
汇率制度历史
Each regime below was presented as the permanent solution to Argentina's monetary problem. Each lasted until the structural contradiction between the two economies overwhelmed it.
下面的每种制度都被作为阿根廷货币问题的永久解决方案提出。每种制度都持续到两个经济体之间的结构性矛盾将其压垮为止。
1 peso = 1 dollar, backed by gold/reserves. Ended inflation overnight. Provided decade of stability — and accumulated a structural trap. Collapsed 2001: $100B default, 5 presidents, unemployment 20%+.
1比索=1美元，以黄金/储备为支撑。一夜之间终结通胀。提供了十年稳定——并积累了结构性陷阱。2001年崩溃：1000亿美元违约，五位总统，失业率超20%。
Post-2001 devaluation to 3:1, then managed float. Soy boom provided dollar cushion. From 2011: capital controls ("cepo"), multiple exchange rates. Structural: suppressed real exchange rate eventually re-accumulated overvaluation.
2001年后贬值至3:1，随后实施管理浮动。大豆繁荣提供了美元缓冲。2011年后：资本管制（"枷锁"），多重汇率。结构上：被压制的实际汇率最终重新积累了高估。
Macri lifted controls, floated peso, set BCRA inflation targets. BCRA raised rates to 40%+ to attract capital. Worked briefly — then the Lebac time bomb exploded in 2018. Rate-hiking cycle accelerated capital flight.
马克里解除管制，比索浮动，设定BCRA通胀目标。BCRA将利率提高至40%以上以吸引资本。短暂奏效——随后莱巴克定时炸弹在2018年爆炸。加息周期加速资本外逃。
Kirchnerist governments imposed increasingly elaborate capital controls. By 2023: 5+ exchange rates, 150%+ blue dollar premium, BCRA reserves negative in net terms. The regime rationed dollars by decree rather than price.
基什内尔主义政府实施了日益复杂的资本管制。到2023年：5种以上汇率、150%以上的蓝市溢价、BCRA净储备为负。该制度通过行政令而非价格来分配美元。
Immediate 54% devaluation on entry, then a "crawling peg" at 2%/month. Multiple rates unified. BCRA cleared Leliq balance sheet. By mid-2025: exchange rate bands introduced, peso broadly stable. Inflation: 211% → 43% annual. Net reserves rebuilding.
上任后立即50%贬值，随后爬行钉住2%/月。多重汇率统一。BCRA清理了莱利克资产负债表。到2025年中：引入汇率区间，比索基本稳定。通胀：211%→43%年化。净储备重建中。

The Dollarization Debate
美元化辩论
Milei campaigned on closing the BCRA and dollarizing Argentina's economy — replacing the peso with the US dollar as legal tender. The appeal is structural: if the BCRA cannot be trusted not to monetize fiscal deficits, remove the capacity to monetize. Ecuador and El Salvador have operated under full dollarization, with mixed results. Ecuador gained monetary credibility but lost the devaluation adjustment tool; during downturns, the entire adjustment falls on wages and employment.
米莱以关闭BCRA并将阿根廷经济美元化为竞选纲领——用美元取代比索作为法定货币。其吸引力是结构性的：如果无法信任BCRA不将财政赤字货币化，就去除货币化的能力。厄瓜多尔和萨尔瓦多已在完全美元化下运营，结果好坏参半。厄瓜多尔获得了货币可信度，但失去了贬值调节工具；在经济下行期，所有调整都落在工资和就业上。
Once in office, Milei effectively dropped formal dollarization as an operational target — Argentina did not hold sufficient dollar reserves to buy back the peso money supply. Instead, he pursued a "de-facto peso stabilization": fiscal surplus eliminates the need for monetary financing, the Leliq bomb is defused, and the peso is stabilized against the dollar via exchange rate bands. Whether this achieves dollarization's benefits without requiring actual dollarization is the central monetary question of the Milei era.
一旦执政，米莱实际上放弃了正式美元化作为操作目标——阿根廷没有足够的美元储备来回购比索货币供应量。相反，他追求"事实上的比索稳定"：财政盈余消除了货币融资需求，莱利克炸弹被拆除，比索通过汇率区间对美元实现稳定。这是否能在不需要实际美元化的情况下实现美元化的好处，是米莱时代的核心货币问题。
"The peso is not the source of Argentina's monetary problem. The peso is the symptom. The source is the structural imbalance between what the economy earns and what the state needs to spend."
"比索不是阿根廷货币问题的根源。比索是症状。根源是经济所赚取的与国家需要支出的之间的结构性失衡。"
After Guillermo Calvo and Carmen Reinhart, on original sin and Latin American monetary regimes 基于吉列尔莫·卡尔沃与卡门·莱因哈特，关于原罪与拉美货币制度Structural verdict. The BCRA's chronic dysfunction is not a story of bad central bankers. It is a story of a monetary institution being asked to solve a problem that cannot be solved by monetary policy: the structural mismatch between an export sector that earns dollars in commodities and an industrial sector that requires subsidized pesos to survive. When export revenues decline, the state runs a deficit. The BCRA monetizes it. Inflation follows. Capital controls stop it from becoming a full run on the peso. Then the controls create the multiple exchange rate distortions that undermine investment and productivity — which reduce export competitiveness — which reduce export revenues — which bring the next deficit. Milei's 2024 achievement (first surplus, inflation falling, reserves rebuilding) is the first time in two decades the monetary cycle has appeared to break. The test is whether the structural productive cycle allows it to hold.
结构性评判。BCRA长期功能失调的故事不是糟糕的央行行长的故事。而是一家货币机构被要求解决货币政策无法解决的问题的故事：以大宗商品赚取美元的出口部门与需要补贴比索才能生存的工业部门之间的结构性错配。当出口收入下降时，国家出现赤字。BCRA将赤字货币化。通胀随之而来。资本管制阻止其演变为对比索的全面挤兑。然后管制制造了破坏投资和生产率的多重汇率扭曲——进而降低出口竞争力——进而减少出口收入——从而带来下一次赤字。米莱2024年的成就（首次盈余、通胀下降、储备重建）是二十年来货币周期看似打破的首次。考验在于结构性生产周期是否允许其持续。
