The legendary Prussian army chief of staff Helmuth von Moltke the Elder famously remarked that no battle plan survives first contact with the enemy.
The implication was that commanders who win wars are not necessarily those with the best initial plans, but those who quickly adapt to new information and to conditions on the ground.
The Ukrainian military’s brilliant counteroffensive, which has forced Russian troops to retreat in eastern and southern Ukraine, is a case in point. A less brilliant example is the West’s effort to use trade and financial sanctions to crimp Russia’s ability to wage war.
Here, things have not gone according to plan, and it is clear that the strategy must be adjusted. To this end, there are several steps that would make the Western sanctions regime more effective.
That regime’s opening salvo looked impressive. Immediately after the invasion, the US, the EU and their allies froze the bulk of Russia’s international reserves, excluded most of its banks from the SWIFT international payment system, and banned the sale of many goods to Russia — including aircraft parts and crucial weapons systems.
They also clumsily tried to curtail Russia’s ability to fund itself through oil and gas exports: The US imposed an immediate oil embargo, while the EU announced it would ban most Russian oil imports within six to eight months.
In addition, hundreds of foreign companies announced that they were exiting the Russian market.
However, while initial forecasts anticipated a double-digit GDP contraction and a ruble collapse, that did not happen. The IMF expects Russian GDP to decline by 3.4 percent this year, while the ruble has increased by about 20 percent relative to prewar levels.
This does not mean that EU-US-led sanctions have not significantly affected Russian President Vladimir Putin’s war-making power.
However, they have been less effective than the US and European governments had hoped.
What went wrong, and what could be done to achieve greater impact?
Financial sanctions aim to leverage the power of the US and its allies over international finance. They are particularly effective when used against countries that run current-account deficits. By preventing those countries from funding themselves, financial sanctions cause a macroeconomic shock that typically leads to a collapse in imports, output and the local currency.
However, financial sanctions are far less effective against countries that, like Russia, run current-account surpluses, because these countries can afford to pay for imports with their earnings from exports. While financial sanctions reduce economic efficiency and affect the ability to fund large, complex projects, these effects apply to future growth, not current output.
The effectiveness of trade sanctions also depends on the context in which they are imposed. In particular, their success depends on each party’s ability to redirect its exports or imports. Sanctioning exports to Russia is not the same as banning imports from Russia in terms of costs and benefits.
Before the war, the EU was almost as dependent on imports of Russian energy as Russia was on selling its oil and gas to the EU, resulting in a de facto bilateral monopoly.
However, while Russian oil giant Rosneft has a dominant position on the Russian side, the EU has many energy-importing firms across 27 member states. Thus, whereas Russia can act, the EU can only struggle to get its act together. By contrast, before the war, Russia sourced 40 percent of its imports from the EU, while the Russian market represented 4 percent of European exports.
The numbers look even more favorable to the anti-Putin coalition as the US and the EU — together with the remaining G7 members, Taiwan, South Korea and Australia — dominate many industries, including aircraft, machinery and medical instruments.
For 30 percent of the products imported by Russia, the coalition’s share of the Russian market exceeded 70 percent before the war. This enables the US and its allies to restrict Russia’s access to critical supplies, which, according to internal Russian documents, might have devastating economic effects in the years to come.
However, current sanctions do not leverage the full potential of restricting exports to Russia. Because these sanctions are biased toward capital goods, they affect production only gradually, as existing Russian equipment depreciates and requires replacement. They do not have the immediate effect on production that disrupting key intermediate inputs would have.
Given the urgency of the war effort, countries must work together to identify and disrupt imports that Russia needs.
The members of the anti-Putin coalition also seem to have serious coordination problems. As of the middle of last month, the EU had banned the export of about 37 percent of all European-made products to Russia, data from the Global Trade Alert showed.
These products account for 45 percent of the EU’s prewar exports to Russia.
However, almost half the products the EU banned are not subject to US export restrictions, and vice versa, enabling Russia to substitute between coalition suppliers.
The Harvard Growth Lab developed a framework for assessing the effectiveness of current export restrictions, synthesizing insights into a single criterion that allows prioritizing bans on exports to Russia of narrowly defined products.
The bottom line is simple: Sanctions on exports to Russia are in general very effective, leading to a percentage loss of GDP that is about 100 times larger for Russia than for the sanctioning countries.
If sanctions were based on the criterion and better coordinated across coalition members, the costs incurred by Russia would increase by about 60 percent with no extra cost for the sanctioning countries. Moreover, there is significant scope for increasing Russia’s losses by restricting more products.
The Ukraine war is being fought both on the battlefield and on the economic front, with millions making sacrifices to protect the country and its democracy. We must support them by ensuring that trade sanctions are as effective as they can be.

A recent report concerning a student who is suing his teacher posed the question in its headline: Does failing a student in two subjects constitute bullying? The college student in Chiayi County apparently sought NT$2 million (US$63,603) in state compensation, but a court dismissed the case. The first reaction of many might have been to ask: What has happened to students nowadays? Some say that teachers have lost their authority, while others say students are overindulged. Some even start reminiscing over the days when “whatever the teacher says goes.” However, the real issue might be overlooked if emotional reactions like that are the
When I visited Taiwan last summer, I called on the nation to use its status as a technology superpower to build superweapons. It is obvious to me as I return a year later that Taiwan is now answering that call. By 2030, Taiwan envisions a domestic drone hub, capable of producing large quantities of drones per year. The nation continues to tighten cooperation across the private sector, scientific researchers and the elected government, on creating new and innovative production avenues for defense, while efforts to become central to the “democratic supply chain” are only increasing. Anduril is seeing all of these positive
Singaporean former Prime Minister and current senior minister Lee Hsien- Loong(李顯龍) last month stood on Chinese soil and told Beijing that Singapore cooperates because of “shared interests”, not because of common “ethnic descent,” a significant statement that has upended China’s cognitive warfare tactics of “ethnic nationalism.” Along with using its military buildup and economic growth to expand its international dominance, China has long deployed ethnic politics to promote the idea that all ethnic Chinese around the world, regardless of citizenship, share a tight bond with the Chinese motherland, by which it means the regime of the People’s Republic of China (PRC)
Taiwan’s economic momentum, driven by demand for artificial intelligence (AI) products, remains strong, with booming demand for advanced semiconductors, servers and key components. In the first quarter, GDP expanded 14.55 percent year-on-year, the second consecutive quarter of double-digit percentage growth and accelerating from the 12.95 percent expansion in the previous quarter, the Directorate-General of Budget, Accounting and Statistics (DGBAS) reported on Friday. Net exports remained the dominant driver of growth, contributing 10.33 percentage points to Taiwan’s GDP growth in the first quarter. That came as exports rose 35.76 percent year-on-year in the first quarter, outpacing 26.34 percent growth in imports, the
