Green Party's Economic Vision Under Scrutiny as Advisors Push Modern Monetary Theory
In a surprising political shift, the Green Party has surged to the top of recent polls, tying for first place while Labour languishes in fourth. This rise brings renewed attention to their economic policies, particularly the advocacy of Modern Monetary Theory (MMT) by several key advisors. MMT posits that governments with control over their own currency can finance unlimited spending by simply printing money, a concept that has sparked intense debate among economists and policymakers.
The Seductive Allure of Unlimited Public Spending
At its core, MMT offers a seemingly simple solution to fiscal challenges: if the NHS requires more funding or benefits need boosting, the Bank of England can just create more money. This approach contrasts sharply with traditional methods, where public sector deficits—the gap between government spending and tax revenue—are typically financed by issuing bonds. These bonds incur interest payments and eventual repayment obligations, whereas printed money, as MMT theorists argue, carries no such burdens. In technical terms, money can be viewed as a "zero coupon perpetual bond," though this terminology is not commonly used by MMT proponents.
The appeal of MMT is not new; it once attracted figures like Jeremy Corbyn during his tenure as Labour Leader. However, his shadow chancellor, John McDonnell, wisely distanced himself from the theory, recognizing the importance of evidence-based policy. McDonnell's caution was informed by historical precedents, such as the experience of Greece's left-wing Syriza party in the late 2010s.
Historical Warnings: Greece and the UK's Financial Missteps
In Greece, soaring public debt and deficits led to demands for austerity from the European Commission, ECB, and IMF. Prime Minister Tsipras called a referendum in June 2015, where voters rejected bailout conditions by a 61-39% margin. Yet, this rejection only intensified external pressure, forcing Tsipras to implement even harsher austerity measures by early July. Despite Greece's inability to print its own money due to Eurozone constraints, the outcome highlighted how perceptions of uncontrolled public finances can trigger market-driven policy reversals.
Closer to home, the UK under Prime Minister Liz Truss provides another cautionary tale. Her unfunded spending plans caused the yield on 10-year bonds to spike from 3% to 4.25% in just one month, precipitating a crisis that ended her brief tenure. Currently, yields hover just under 5%, underscoring the ongoing volatility. Unlike Greece, the UK could print money, but this made no difference; bond markets still forced a rapid policy reversal when finances appeared unstable.
The Fantasy of Unlimited Spending and Its Political Consequences
Advocates of MMT often attract voters with promises of pain-free public investment, but reality tells a different story. The Greek experiment ended in tragedy, and if the Green Party were to embrace similar policies, it could result in farce. The world of unlimited public spending remains a fantasy, as evidenced by past failures. While wishful thinking may appeal to some, the lessons from history are clear: financial markets will not tolerate perceived fiscal irresponsibility, regardless of monetary sovereignty.
Paul Ormerod, an Honorary Professor at the Alliance Business School at the University of Manchester, emphasizes that evidence should guide economic policy, not ideological fervor. As the Green Party gains traction, their reliance on MMT could prove a critical vulnerability, risking a repeat of past disasters.
