NEW YORK – China’s management of its exchange-rate peg continues to rattle global financial markets. Ongoing uncertainty about renminbi devaluation is fueling fears that deflationary forces will sweep through emerging markets and deliver a body blow to developed economies, where interest rates are at or near zero (and thus cannot be lowered to defend against imported deflation). Fiscal gridlock in both Europe and the United States is heightening the angst.

But the current bout of exchange-rate anxiety is really just a symptom of the fact that China’s transition from an export-led growth strategy to one propelled by domestic consumption is proceeding far less smoothly than hoped.

For some people, visions of the wonders of capitalism with Chinese characteristics remain undiminished. They are certain that, after more than three decades of state-directed growth, China’s leaders know what to do to turn their slumping economy around.

The optimists’ unreality is rivaled by that of supply-siders, who would apply shock therapy to China’s slumping state sector and immediately integrate the country’s underdeveloped capital markets into today’s turbulent global financial system. That is a profoundly dangerous prescription. The power of the market to transform China will not be unleashed in a stagnant economy, where such measures would aggravate deflationary forces and produce a calamity.

The persistent downward pressure on the renminbi reflects a growing fear that Chinese policymakers have no coherent solution to the dilemmas they face. Floating the renminbi, for example, is a dangerous option. After all, with the Chinese economy undergoing wholesale economic transformation, estimating a long-term equilibrium exchange rate that will anchor speculation is virtually impossible, particularly given persistent doubts about data quality, disclosure, and opaque policymaking processes.

But if the current exchange-rate peg to a basket of currencies fails to anchor the renminbi and prevent sharp depreciation, the deflationary consequences for the world economy will be profound. Moreover, they will feed back on the Chinese export sector, thus dampening the stimulative impact of a weakened currency.

The key to stabilizing the exchange rate lies in creating a credible development policy. Only then will the pressure on the renminbi, and on China’s foreign-exchange reserves, subside, because investors both within and outside the country will see a clear way forward.

Establishing policy credibility will require diminishing the muddled microeconomic incentives of state control and guarantees. It will also require reinvigorating aggregate demand by targeting fiscal policy to support the emerging economic sectors that will underpin the new growth model.

But, as usual with China, such a strategy is riddled with contradictions. For example, reducing the size of the state-enterprise sector is necessary, yet would be certain to depress aggregate demand at a time when demand is already soft. Likewise, cutting fiscal support (via government-directed bank lending) to zombie firms would free up fiscal capacity and enable resources to be redirected to new sectors that facilitate services and urban employment; but this would exacerbate – at least at first – today’s demand shortfall.

Slashing the state sector abruptly and expecting to achieve transformation through austerity is not the way forward. Economic historians, notably Michael A. Bernstein in his study of the Great Depression in the United States, have convincingly shown that an economy in transition requires strong aggregate demand to pull resources into new sectors. If both the old and new sectors of an economy are in a slump, capital formation will sputter, investment in upgrading human capital will decline, and structural adjustment will stall. Robust aggregate demand is always essential to successful transformation.

An equally large obstacle to China’s economic transition – the problem that almost dare not speak its name – is the widespread worship of China’s hybrid market economy. Simply put, today’s muddled market incentives impede transformation by favoring state-owned enterprises.In early 2012, when the Chinese leadership moved toward stronger private ownership, stocks in the private-sector sub-index outperformed the state-owned sector sub-index on both the Shanghai and Hong Kong stock exchanges. But since the spring of 2014, this trend has reversed, and the state-owned sector sub-index has outperformed the private-sector sub-index. As the Chinese economy slows and default risk grows, the value of state guarantees rises, directing capital away from private-sector growth.
