Foreign holdings of U.S. Treasuries and U.S. Treasury yields

Foreign official holdings of U.S. Treasuries increased from $400 billion in January 1994 to about $3 trillion in June 2010. Most of this growth is accounted for by a handful of emerging market economies that have been running large current account surpluses. These countries are channeling their savings through the official sector, which is then acquiring foreign exchange reserves. Any shift in policy to reduce their current account surpluses or dampen the rate of reserves accumulation would likely slow the pace of foreign official purchases of U.S. Treasuries. Would such a slowing of foreign official purchases of Treasury notes and bonds affect long-term Treasury yields? Most likely yes, and the effects appear to be large. By our estimates, if foreign official inflows into U.S. Treasuries were to decrease in a given month by $100 billion, 5-year Treasury rates would rise by about 40–60 basis points in the short run. But once we allow foreign private investors to react to the yield change induced by the shock to foreign official inflows, the long-run effect is about 20 basis points.     

美国国际投资头寸的规模与结构变迁

20世纪80年代以来,美国的对外债权和对外债务相对快速增长,由于对外债务的增速快于对外债权的增速,形成了庞大的美国国际投资净债务头寸,美国已经由一个对外净债权国演变成一个对外净债务国,而且对外净债务还在急速膨胀。美国政府部门对外净债务是美国对外净债务头寸的主要构成部分,外国政府部门则持有大部分对美国的净债券,正是庞大的美国政府财政赤字造成了美国的对外净债务,也正是外国政府部门持有的外汇储备支撑了美国政府的财政赤字。     

Analysis of U.S. savings bonds

U.S. savings bonds are complex contracts. Financial planners have traditionally paid little attention to savings bonds, in part because they often offer below-market interest rates. However, they sometimes offer above-market interest rates, especially when one learns how to view and value their option features. All savings bonds contain put options that protect the investor against a rise in interest rates. Thus, they can be viewed as short-term, intermediate-term, or long-term bonds. The EE bonds also offer several tax options. We show how savings bonds can be used to beat the kiddie tax, to finance postsecondary education, and in retirement planning.     

中国外汇储备的构成、收益与风险

基于美国财政部国际资本系统(TIC)的数据,本文对中国外汇储备的币种和证券资产构成进行推测,并估算其成本与收益,分析潜在的资本风险。本文结论显示,绝大部分中国外汇储备被用于美元、欧元资产的投资,其中,美国的国债和机构债券占主体地位。若以美元计价,2000~2009年中国外汇储备的平均收益率尚达4%~5%;若以人民币计价,汇改前的平均收益率为5.54%,汇改后仅为1%。在剔除外汇冲销成本之后,汇改前的平均净收益率为3.59%,汇改后为-1.64%。与低收益率不相匹配的是,中国外汇储备面临着较高的资本损失风险,如两房机构债券违约风险、利率(通货膨胀)风险和汇率风险等。     

Convergence of Real Capital Market Interest Rates—Evidence from Inflation Indexed Bonds

This paper investigates the convergence of long‐term ex ante real interest rates (RIRs) obtained from Canadian, French, UK, and U.S. inflation indexed government bonds. In contrast to previous research, our evidence suggests full convergence in the long run and, hence, capital market integration. For the same sample period, global convergence is rejected for RIRs measured in conventional terms. From these results, we conclude that previous tests of the long‐run real interest rate parity might have suffered from weak measurement of real capital market interest rates.     

Interest Rates and Exchange Rate Movements: Analyzing Short-term Investments in Long-term Bonds

Tests of the uncovered interest rate parity (UIP) are subject to various data problems when long-term interest rates are applied: due to the long investment period, time intervals for measuring exchange rate movements are usually overlapping and therefore not independent. This shortfall can be prevented by considering short-term investments in long-term bonds instead of investments to maturity. This article analyzes the explanatory power of long-term interest rates with regard to 1- and 3-month exchange rate movements by relating return differences from 1- and 3-month investments in domestic and foreign 10-year government bonds to nine different exchange rates. From a Swiss perspective, there is only weak support for an interrelation between return differences and the corresponding exchange rate movements, whereas from a US perspective, the resulting estimates are much more in line with UIP.The reader may for instance consider Engel (1996) and Froot and Thaler (1990).     

一个有远见的税收制度应当关注未来的税基——特朗普新税法的成本分析及政策建议

20世纪50年代以来,美国企业所得税税率持续下降,政府税收收入也处于较低水平。2017年,特朗普新税法的实施大幅度降低了企业所得税税率,导致政府税收损失远超预期。然而,新税法实施后,美国企业投资和长期经济增长并没有明显改善。本文认为,一个国家经济效率主要取决于税基而非税率,美国政府应通过税收制度改革,增加对企业投资和研发投入的激励,从而扩大税基,实现经济的长期改善。     

从中美经济相互依存看我国高额外汇储备管理

美债危机爆发后,中国作为美国在海外最大的债券持有者仍然不得不继续增持美债,一方面是由于人民币汇率长期与美元挂钩,国际贸易和金融交易主要以美元结算以及我国出口导向型经济增长方式短期内无法改变均导致外汇储备被动积累,另一方面更是因为一旦我国大规模减持美元资产,将引起全球外汇市场对美元的恐慌性抛售,并最终危及我国在美金融资产安全。美债危机表明我国经济对美国高度依赖,并凸显了经济增长方式转变以及对高额外汇储备有效管理的重要性与紧迫性。     

Using Financial Accounting Data to Examine the Effect of Foreign Operations Located in Tax Havens and Other Countries on U.S. Multinational Firms' Tax Rates

This paper investigates the effect tax havens and other foreign jurisdictions have on the income tax rates of multinational firms based in the United States. We develop a new regression methodology using financial accounting data to estimate the average worldwide, federal, and foreign tax rates on worldwide, federal, and foreign pretax book income for a large sample of U.S. firms with and without tax haven operations. We find that on average U.S. firms that disclosed material operations in at least one tax haven country have a worldwide tax burden on worldwide income that is approximately 1.5 percentage points lower than firms without operations in at least one tax haven country. Our results also show that U.S. firms face a 4.4% current federal tax rate on foreign income whether or not they have tax haven operations. Finally, we find that U.S. firms with operations in some tax haven countries have higher federal tax rates on foreign income than other firms. This result suggests that in some cases, tax haven operations may increase U.S. tax collections at the expense of foreign country tax collections.     

美国量化宽松货币政策与人民币的国际化

2008年国际金融危机的爆发和美国量化宽松货币政策的实施,导致我国外汇储备管理风险剧增,由此,我国加快推进人民币国际化战略目标下各项政策措施的出台。为应对量化宽松货币政策下美元流动性的泛滥,我国连续上调了金融机构的存贷款利率和存款准备金率。人民币升值压力增大,套汇、套利等投机交易下的短期资本流动风险加剧,增加了人民币国际化进程中的风险。对此,本文提出了在当前国际经济金融环境下人民币国际化发展的对策建议。     

U.S. Monetary Policy and International Bond Markets

This paper analyzes how U.S. monetary policy affects the pricing of dollar‐denominated sovereign debt. We document that yields on dollar‐denominated sovereign bonds are highly responsive to U.S. monetary policy surprises—during both the conventional and unconventional policy regimes—and that the passthrough of unconventional policy to foreign bond yields is, on balance, comparable to that of conventional policy. In addition, a conventional U.S. monetary easing (tightening) leads to a significant narrowing (widening) of credit spreads on sovereign bonds issued by countries with a speculative‐grade credit rating but has no effect on the corresponding weighted average of bilateral exchange rates for a basket of currencies from the same set of risky countries; this indicates that an unanticipated tightening of U.S. monetary policy widens credit spreads on risky sovereign debt directly through the financial channel, as opposed to indirectly through the exchange rate channel. During the unconventional policy regime, yields on both investment‐ and speculative‐grade sovereign bonds move one‐to‐one with policy‐induced fluctuations in yields on comparable U.S. Treasuries. We also examine whether the response of sovereign credit spreads to US monetary policy differs between policy easings and tightenings and find no evidence of such asymmetry.     

Foreign issuers in the U.S. PIPE market

We document that the use of private investment in public equity (PIPE) by foreign firms listed on U.S. exchanges is growing even faster than its use by U.S. firms. On average, foreign firm PIPE stock deals represent a similar proportion of the firm's market capitalization to U.S. firm PIPEs, but suffer less of a share price discount than U.S. firm PIPE issuances, a relation that is robust to consideration of exchange, deal size, share turnover and return volatility. We document that hedge funds are only small investors in foreign firm PIPEs issued in the U.S., which tend to be purchased by pensions, government funds and corporations. PIPE, in combination with the reverse merger method of going public, provides a cost-effective means for foreign firms to raise capital in the U.S. capital market.     

Impact of foreign operations on reported effective tax rates: interplay of foreign taxes, U.S. taxes and U.S. GAAP

Effective tax rates can have a significant effect on a firm’s cash flows and reported earnings. As the operations of U.S. companies become increasingly global in scope, an important issue is how their foreign operations impact their effective tax rates, and, in turn, their reported earnings. This study describes how foreign taxes, U.S. taxes, and U.S. accounting principles interact to determine the impact of foreign operations on a firm’s effective tax rate. This analysis will assist users of financial statements in assessing the quality of earnings, making interfirm comparisons, evaluating the performance of management, judging the risks of additional tax assessments, and predicting future effective tax rates.     

Co-integrating currencies and yield differentials

This study investigates the relationship between currencies and interest rates of different maturity horizons. The real exchange rate is found to depend both on short-term real domestic and foreign interest rate difference and on long-term real domestic and foreign interest rate difference. Co-integrating regressions of contemporaneous currency rates generate negative and significant coefficients for long-term rate differentials, consistent with uncovered interest parity. Therefore, the expectations hypothesis holds for long horizons. On the other hand, positive coefficients for real short-term interest rate differentials reveal the forward premium puzzle: the failure of uncovered interest parity for short-horizons. Results are partly driven by the very different risk characteristics of short-term bonds and foreign bonds.     

Official Demand for U.S. Debt: Implications for U.S. Real Rates

We estimate a structural term-structure model of U.S. real rates, where arbitrageurs accommodate demand pressures exerted by domestic and foreign official investors. Official demand affects rates by altering the aggregate price of duration risk, and thereby bond risk premiums. Although foreign central banks' demand contributed to reduce long-term real rates mainly in the years prior to the global-financial crisis, the Federal Reserve's demand lowered rates during the quantitative easing period. Overall, the two-factor model, augmented to account for changing liquidity conditions, offers a good representation of real rates during the 2001–16 period; however, we flag some caveats and possible extensions.     

The Effects of Inverted Yield Curves on Asset Returns

Between 1954 and 1991, U.S. stocks, long-term government bonds, and corporate bonds show negative risk premiums during periods preceded by inverted yield curves. Intermediate-term government bonds do not. Going from safer to riskier asset classes, the negative risk premiums increase in absolute value and statistical significance. The consumption CAPM offers a possible explanation for the negative risk premiums. A negative covariance between the growth rate of consumption and the premium on the risky assets will result in a negative risk premium. Empirical tests of the conditional covariance show that the consumption CAPM does not explain the phenomena.     

Do foreign purchases of U.S. stocks help the U.S. stock market?

This paper investigates the relationship between the U.S. S&P 500 stock market and purchases of U.S. corporation stocks by foreign investors. Estimations using monthly data from 1978:1 to 2008:7 under various methodologies show that, controlling for asset prices (interest rates and the yield curve) and inflation, purchases of U.S. stocks by foreign investors have a positive and statistically significant impact on the U.S. stock market performance. We also show that their relationship is time variant. In a global world, the demand-side variable captured by the foreign appetite for U.S. stocks attenuates the negative effects associated with the domestic forces.     

One-Way Treaty with the World: The U.S. Withholding Tax and the Netherlands Antilles

This paper chronicles the experiences of the U.S. withholding tax on interest income. In 1984, the U.S. repealed its 30 percent withholding tax on interest income paid to foreign persons or corporations. While the tax raised little revenue, it had imposed substantial implicit costs on U.S. corporate borrowers. Since, prior to repeal, domestically issued bonds were subject either to withholding or strict information requirements, many U.S. multinationals raised funds through foreign finance subsidiaries, primarily in the Netherlands Antilles, to avoid the tax. Although the withholding tax rate was effectively reduced to zero in the U.S., this paper demonstrates that interest flows were highly sensitive to their after-tax cost.     

U.S. Equity Investment in Emerging Stock Markets

This article examines U.S. equity flows to emerging stock marketsfrom 1978 to 1991 and draws three main conclusions. First, despitethe recent increase in U.S. equity investment in emerging stockmarkets, the U.S. portfolio remains strongly biased toward domesticequities. Second, of the fraction of the U.S. portfolio thatis allocated to foreign equity investment, the share investedin emerging stock markets is roughly proportional to the shareof the emerging stock markets in the global market capitalizationvalue. Third, the volatility of U.S. transactions in emerging-marketequities is higher than in other foreign equities. The normalizedvolatility of U.S. transactions appears to be falling over time,however, and we find no relation between the volume of U.S.transactions in foreign equity and local turnover rates or volatilityof stock returns.     

Investor yield and gross underwriting spread comparisons among U.S. dollar domestic,Yankee, Eurodollar,and global bonds

The characteristics and features of domestic, foreign, Eurobonds, and global bonds differ from one another, as do their regulation. We develop regression models to compare investor yield differences that should logically exist at issuance for these bond market segments for U.S. dollar denominated bonds. Our empirical results show that, ceteris paribus, both privately placed and Rule 144A Eurodollar issues yield more than publicly placed bonds; Yankee bonds yield insignificantly more than domestic bonds; and, the bearer feature common to Eurodollar bonds is not prized enough by institutional investors for them to accept a lower yield relative to domestic or Yankee bonds. We do not find a statistically significant difference between the investor yield spread on U.S. dollar global bonds and U.S. domestic bonds, or Yankee bonds, or Eurodollar bonds. We also study underwriting costs of publicly traded bonds and find, ceteris paribus, that Eurodollar bonds are far more costly for the firm to issue than domestic bonds, Yankee bonds, or global bonds; domestic and Yankee bonds are more expensive than global bonds; and, there is no significant cost difference between domestic and Yankee bonds.
